To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance of studied climatic, host-related and geographic factors on differences in tree-associated communities.

To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance of studied climatic, host-related and geographic factors on differences in tree-associated communities.

Altogether 54 species and 876 individuals of birds were captured during 24 days of eight trapping sessions (in 84 m of mist-nets at 7.3 ha study plot). The highest number of mist-netted species and individuals was found in July (36 species, 290 individuals), the lowest was in December (16 species, 153 individuals), pooled for both years. The most abundant species were breeding species Sylvia atricapilla, Parus major, Cyanistes caeruleus and Turdus merula. The characteristic reedbed birds included four Acrocephalus species, Locustella luscinioides, Emberiza schoeniclus, and scrubland species Luscinia megarhynchos, Sylvia communis and Remiz pendulinus. Seasonal differences in species number and abundance are discussed. Regular wintering was found in migratory species Prunella modularis and Erithacus rubecula north of the known winter quarters of their central European breeding populations.

Altogether 54 species and 876 individuals of birds were captured during 24 days of eight trapping sessions (in 84 m of mist-nets at 7.3 ha study plot). The highest number of mist-netted species and individuals was found in July (36 species, 290 individuals), the lowest was in December (16 species, 153 individuals), pooled for both years. The most abundant species were breeding species Sylvia atricapilla, Parus major, Cyanistes caeruleus and Turdus merula. The characteristic reedbed birds included four Acrocephalus species, Locustella luscinioides, Emberiza schoeniclus, and scrubland species Luscinia megarhynchos, Sylvia communis and Remiz pendulinus. Seasonal differences in species number and abundance are discussed. Regular wintering was found in migratory species Prunella modularis and Erithacus rubecula north of the known winter quarters of their central European breeding populations.

The insecticide potential of Greek oregano, Origanum vulgare subsp. hirtum, essential oil (EO) and the entomopathogenic fungus Metarhizium pemphigi were evaluated against WCR adults in laboratory conditions as alternative control agents. Pure undissolved Greek oregano EO applied at a volume of 3, 5 and 10 µl caused 97–100% mean corrected mortality of the test individuals with a rapid lethal effect. Treatment of WCR with four concentrations of EO (0.01, 0.1, 1 and 10 µl/ml) showed a strong concentration–time effect. Mortality rate increased with increasing concentration and exposure time. The median lethal concentration LC50 was 0.03 µl/ml.

We compared results from both methods and analysed seasonal and habitat associations with bat species that utilize the semi-arid Mediterranean landscape. Six selected bat species were associated with a total of 20 habitat types. The most frequent species, Pipistrellus kuhlii, was associated with almost all habitat types, with the highest flight activity in agricultural, urbanized and forested / seminatural habitats. Eptesicus serotinus and Hypsugo savii indicated preference of agricultural areas and avoidance of artificial surfaces. A χ2 test of independence revealed stronger habitat associations for stationary surveys, while habitat associations were weak for mobile transects. Given the vulnerability of Mediterranean landscapes, our study could be considered as a basis for establishing a long-term monitoring scheme with the goal of documenting predicted changes in bat communities as habitat is altered and as global temperatures rise. |

Based on multiplex PCR analysis of 11 microsatellite markers screened on 253 D. septosporum isolates obtained from 32 sites across Slovakia, a total of 137 unique multilocus haplotypes (MLHs) were detected. The majority of MLHs (n = 91) were represented by a single isolate, but 13 MLHs were found at two different sites, and in some cases, these were separated by large distances. Four population clusters were identified using a discriminant analysis of principal components (DAPC). The genetic clusters obtained from the DAPC were mixed throughout the country and were not restricted to particular host species. Although both mating types of D. septosporum were found to be in an almost perfect 1:1 ratio in both the non-clone-corrected and clone-corrected datasets, random mating was rejected in the entire dataset. Random mating was only supported in the Pinus mugo group planted in urban areas and on a smaller spatial scale in two sites (Kálnica and Litava) using the clonecorrected dataset.

Based on multiplex PCR analysis of 11 microsatellite markers screened on 253 D. septosporum isolates obtained from 32 sites across Slovakia, a total of 137 unique multilocus haplotypes (MLHs) were detected. The majority of MLHs (n = 91) were represented by a single isolate, but 13 MLHs were found at two different sites, and in some cases, these were separated by large distances. Four population clusters were identified using a discriminant analysis of principal components (DAPC). The genetic clusters obtained from the DAPC were mixed throughout the country and were not restricted to particular host species. Although both mating types of D. septosporum were found to be in an almost perfect 1:1 ratio in both the non-clone-corrected and clone-corrected datasets, random mating was rejected in the entire dataset. Random mating was only supported in the Pinus mugo group planted in urban areas and on a smaller spatial scale in two sites (Kálnica and Litava) using the clonecorrected dataset. These findings suggest a mixed mode of reproduction with an important component of sexual reproduction, although the sexual stage of the fungus (teleomorph) has not been physically observed in Slovakia yet.

Two techniques of chlorophyll a fluorescence and analyses of assimilatory pigments were used to detect the changes in photosynthesis functioning.

We investigated the state of three disturbed spruce stands along an altitudinal gradient in Tatra National Park (Slovakia) through various physiological processes. Tree-growth characteristics, the mineral nutrition in the needles, and photosynthetic efficiency were assessed. Two techniques of chlorophyll a fluorescence and analyses of assimilatory pigments were used to detect the changes in photosynthesis functioning.

Large-scale windthrows trigger population growth of the European spruce bark beetle (Ips typographus L.) from endemic to epidemic levels, thereby allowing the killing of Norway spruce trees over several consecutive years. Background and Objectives: There is a lack of evidence to differentiate how outbreaks are promoted by the effects of environmental variables versus beetle preferences of trees from endemic to outbreak. However, little is known about how individual downed-tree characteristics and local conditions such as tree orientation and solar radiation affect beetle colonization of downed trees. Materials and Methods: To answer this question, we investigated the infestation rates and determined tree death categories (uprooted, broken, and stump) in wind-damaged areas in Western Tatra Mts. in Carpathians (Slovakia) from 2014–2016, following a windthrow in May 2014. In total, we investigated 225 trees over eight transects. For every tree, we measured its morphological (tree height, crown characteristics), environmental (solar radiation, terrain conditions, trunk zenith), temporal (time since wind damage), and beetle infestation (presence, location of attack, bark desiccation) parameters. We applied Generalized Additive Mixed Models (GAMM) to unravel the main drivers of I. typographus infestations. Results: Over the first year, beetles preferred to attack broken trees and sun-exposed trunk sides over uprooted trees; the infestation on shaded sides started in the second year along with the infestation of uprooted trees with lower desiccation rates. We found that time since wind damage, stem length, and incident solar radiation increased the probability of beetle infestation, although both solar radiation and trunk zenith exhibited nonlinear variability. Our novel variable trunk zenith appeared to be an important predictor of bark beetle infestation probability. We conclude that trunk zenith as a simple measure defining the position of downed trees over the terrain can anticipate beetle infestation. Conclusions: Our findings contribute to understanding of the bark beetle’s preferences to colonize windthrown trees in the initial years after the primary wind damage.

This paper describes the step-by-step process that developed a comprehensive and shared definition of CSF, and the process for selecting indicators that assess the “climate-smartness” of forest management. Adaptation, mitigation and social dimensions are the core focus of the CSF definition, which recognises the need to integrate and avoid development of these aspects in isolation. An iterative participatory process was used with a range of experts in forest-related fields from the CLIMO project, this was subsequently supported by a network analysis to identify sustainable forest management indicators important to CSF.

Specific CSF strategies are viewed as a way forward for developing suitable management responses and enhancing the provision of ecosystem services. However, there is currently a lack of comprehensive and cohesive assessment to implement CSF. This paper describes the step-by-step process that developed a comprehensive and shared definition of CSF, and the process for selecting indicators that assess the “climate-smartness” of forest management. Adaptation, mitigation and social dimensions are the core focus of the CSF definition, which recognises the need to integrate and avoid development of these aspects in isolation. An iterative participatory process was used with a range of experts in forest-related fields from the CLIMO project, this was subsequently supported by a network analysis to identify sustainable forest management indicators important to CSF. The definition developed here, is an important first step in to promote CSF that will aid practice in the forestry sector. It can be used as a template across Europe, tailored to local contexts. Further work communicating CSF to practitioners and policy-makers will create a CSF practice and culture that will help to safeguard future forest economies and communities. |

Altogether, we found 129 species (59 Ensifera, 70 Caelifera) in the fauna of Slovakia, based on a critical revision of museum collections, all records published since 1826 and our own unpublished data from mapping in 1994–2019 (~2000 sites located in 97.5% of the mapping grid cells). Forty-four species reach the limit of their distributional range within the country, and 31 have their northern limit there. Four species are endemic to Slovakia. In total, 11 species were erroneously reported from the country and are not included in this checklist. The relatively rich species spectrum reflects the diversity of habitats in an area of about 50 thousand km2 and elevations from 94 to 2,655 masl. We found 30 species exclusive for the Pannonian and 18 for the Alpine biogeographical region in the study area. We emphasize changes compared to previous species lists published in 1977 and 1999, when nine species were first recorded after 1999, and eight other species have been missing for more than 50 years. Distributional patterns, accompanied by site maps, are commented for 42 species. Taxonomic, nomenclatural and zoogeographical problems are discussed for a further 23 species. Based on the actual IUCN Red List criteria, we assessed all 129 species. The species were red-listed as follows: regional extinct (Celes variabilis), critically endangered (Isophya beybienkoi, I. costata, Poecilimon fussii, Pachytrachis gracilis, Saga pedo, Paracaloptenus caloptenoides, Acrotylus insubricus, Stenobothrus fischeri), endangered (Poecilimon intermedius, Gampsocleis glabra, Pholidoptera frivaldszkyi, Myrmeleotettix antennatus), vulnerable (nine species), near threatened (18) and data deficient (12).

Altogether, we found 129 species (59 Ensifera, 70 Caelifera) in the fauna of Slovakia, based on a critical revision of museum collections, all records published since 1826 and our own unpublished data from mapping in 1994–2019 (~2000 sites located in 97.5% of the mapping grid cells). Forty-four species reach the limit of their distributional range within the country, and 31 have their northern limit there. Four species are endemic to Slovakia. In total, 11 species were erroneously reported from the country and are not included in this checklist. The relatively rich species spectrum reflects the diversity of habitats in an area of about 50 thousand km2 and elevations from 94 to 2,655 masl. We found 30 species exclusive for the Pannonian and 18 for the Alpine biogeographical region in the study area. We emphasize changes compared to previous species lists published in 1977 and 1999, when nine species were first recorded after 1999, and eight other species have been missing for more than 50 years. Distributional patterns, accompanied by site maps, are commented for 42 species. Taxonomic, nomenclatural and zoogeographical problems are discussed for a further 23 species. Based on the actual IUCN Red List criteria, we assessed all 129 species. The species were red-listed as follows: regional extinct (Celes variabilis), critically endangered (Isophya beybienkoi, I. costata, Poecilimon fussii, Pachytrachis gracilis, Saga pedo, Paracaloptenus caloptenoides, Acrotylus insubricus, Stenobothrus fischeri), endangered (Poecilimon intermedius, Gampsocleis glabra, Pholidoptera frivaldszkyi, Myrmeleotettix antennatus), vulnerable (nine species), near threatened (18) and data deficient (12).

The aim of the study was to investigate the physiological responses of eight-month-old seedlings, as a most vulnerable phase of forest tree life, for different spruce provenances, to find out variable strategies in relation to controlled drought stress. Materials and Methods: We performed an experiment under controlled conditions with spruce seedlings from a climatologically warmer stand of 410 m above sea level (a.s.l.), and a moderately cool stand of 931 m a.s.l. The soil water content, leaf predawn water potential, the osmotic potential of needles, the relative water content of needles, and the photosynthetic performance and the contents of primary metabolites (proline and abscisic acid) were investigated as indicators of the spruce seedlings’ responses to water stress. The status of the indicators was analyzed at different temporal intervals, using repeated measures analysis of variance (ANOVA), reflecting the seedlings’ water conditions (early drought, drought, or recovery). On a daily basis, the differences among the indicators were tested with one-way ANOVA. A principal component analysis (PCA) was used to identify the provenance-specific responses of tree drought indicators in a multi-dimensional data set. Results: The responses to drought stress differed between the provenances. Whereas seedlings of ‘warm’ provenance from a low altitude performed a conservation strategy, with high amounts of accumulated abscisic acid and closing the stomata faster, the reactions of ‘cool’ provenance seedlings from a higher altitude were not so sensitive and the plants’ water supply and photosynthetic performance remained significantly higher. These findings indicate that a higher drought resistance in ‘cool’ provenance could be related to greater amounts of proline amino-acids, which are accumulated from the beginning of the drought simulation. Furthermore, proline accumulation resulting in increased stress tolerance is controlled through another mechanism than osmotic adjustment. Conclusions: The observed variations in the regulatory mechanisms used to develop adaptive strategies in different provenances are an important factor for seedling survival under a changing climate.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Research Highlights: In this study, we found different regulatory mechanisms in two contrasting provenances of Norway spruce responding to progressive drought stress.

While the consumption of herb seeds has been intensively studied, little attention has been paid to the consumption of seeds of gymnosperm plants. Here, we determined the consumption of seeds of six coniferous species by four common carabid species and compared carabid preference for conifer and selected common angiosperm weed seed species. In no-choice experiments, the large carabid species Pseudoophonus rufipes preferentially consumed the seeds of Picea abies, Larix decidua and Pinus sylvestris. Pinus sylvestris was also preferred by another large carabid, Pterostichus melanarius. The smaller carabids Harpalus affinis and H. rubripes consumed conifer seeds reluctantly. The intensity of seed consumption by carabids decreased with increasing seed size.

While the consumption of herb seeds has been intensively studied, little attention has been paid to the consumption of seeds of gymnosperm plants. Here, we determined the consumption of seeds of six coniferous species by four common carabid species and compared carabid preference for conifer and selected common angiosperm weed seed species. In no-choice experiments, the large carabid species Pseudoophonus rufipes preferentially consumed the seeds of Picea abies, Larix decidua and Pinus sylvestris. Pinus sylvestris was also preferred by another large carabid, Pterostichus melanarius. The smaller carabids Harpalus affinis and H. rubripes consumed conifer seeds reluctantly. The intensity of seed consumption by carabids decreased with increasing seed size. In choice experiments, both of the large carabid species preferred the small conifer seeds of P. sylvestris and L. decidua over herb seeds of similar size (Dipsacus fullonum, Galeopsis speciosa, Polygonum lapathifolium). Carabids may prefer conifer seeds because of their soft seed coats, regardless of their chemical protections. Postdispersal predation of seeds by carabids may be an important mortality factor in some conifer species. |

The selected strains demonstrated high virulence to leaf miner pupae after a topical treatment with spore suspensions. LC50 ranged between 2.49 and 3.19 × 106 conidia ml−1. Horse-chestnut saplings were inoculated with the fungi through their direct immersion into spore suspensions (107 conidia ml−1). Endophytic colonization was successful and a mean colonization rate reached 57.44–66.08% 15 days post-inoculation. It decreased over time for all strains, but the fungi were still present in leaf tissue 54 days post-inoculation. AM_EF0111 strain was significantly more effective in colonizing saplings than AM_SO1015 and AM_EP0715. Fungus-colonized and untreated (control) saplings were infested with the leaf miner 31 days after inoculation and development of larval mines was monitored. In Beauveria-colonized saplings, damage by leaf miner was significantly lower compared to control plants. On day 23 post-infestation, the damaged leaf area of colonized leaves was 5-times smaller compared to control saplings. The negative effect on larval tunneling was significantly greater for strain AM_EP0715 than for the other two strains. Survival of leaf miners was considerably affected in colonized leaves, but mycosis was detected only in 5.41–9.23% of cadavers. No mycosed individuals were collected from control saplings.

The selected strains demonstrated high virulence to leaf miner pupae after a topical treatment with spore suspensions. LC50 ranged between 2.49 and 3.19 × 106 conidia ml−1. Horse-chestnut saplings were inoculated with the fungi through their direct immersion into spore suspensions (107 conidia ml−1). Endophytic colonization was successful and a mean colonization rate reached 57.44–66.08% 15 days post-inoculation. It decreased over time for all strains, but the fungi were still present in leaf tissue 54 days post-inoculation. AM_EF0111 strain was significantly more effective in colonizing saplings than AM_SO1015 and AM_EP0715. Fungus-colonized and untreated (control) saplings were infested with the leaf miner 31 days after inoculation and development of larval mines was monitored. In Beauveria-colonized saplings, damage by leaf miner was significantly lower compared to control plants. On day 23 post-infestation, the damaged leaf area of colonized leaves was 5-times smaller compared to control saplings. The negative effect on larval tunneling was significantly greater for strain AM_EP0715 than for the other two strains. Survival of leaf miners was considerably affected in colonized leaves, but mycosis was detected only in 5.41–9.23% of cadavers. No mycosed individuals were collected from control saplings. Pupae from colonized leaves were smaller in dimensions with lower weight than pupae form control plants. The same Beauveria strains recovered from leaves at the end of colonization bioassays showed no significant decrease in LC50 values. |

Multi-locus phylogenetic reconstruction recognised two distinct clades morphologically corresponding to this species concept. The limited morphological description in the protologue of H. atropunctus and absence of a type specimen were limitations in an assignment of this name to one of the recognised phylogenetic species. The emended species concept and the selection of a neotype are based on careful analyses of the colour of the basidiomata and how this changes during maturation and drying. The name H. atropunctus is assigned to the paler of the two species which also shows colour change across the pileus and along the length of the stipe when dry.

To assess the rhododendron collection´s stability, its drought and frost injury level were tested in field, in summer 2015 and winter 2017, respectively. The tested parameters were: leaf wilting and electrolyte leakage combined with shrub leaf area, insolation level and overall health state. We found that the drought effect was strong or very strong in only ca. 30% rhododendron species and ca. 10% rhododendron cultivars, and that around 60% shrubs showed no or only moderate symptoms of water deficit. The drought injury level was only associated with the genotype. The most tolerant / sensitive genotypes, commonly occurring in the park, were: R. catawbiense, R. ponticum, R. smirnowii, cv. ´Boursault´, cv. ´Cunningham´s White´ and cv. ´Purpureum Elegans´ / R. fortunei and cv. ´Tamarindos´. On the other hand, the most frequent response to frost in the observed rhododendron genotypes was moderate injury (28 and 37% for species and cultivars, respectively), nevertheless more than 18% species and almost 6% cultivars exhibited strong frost damage.

Two spring phenological phases – bud-burst and leaf unfolding 50% as well as two autumnal phases – leaf discolouration 10% and 50%, respectively were monitored over the period of twenty years (1995–2014). Analysis of the air temperature showed its increasing values mainly in the period from April to August. On the other hand, the values of cumulative rainfall totals for the period from May to August had not clear trend. They were strongly volatile among the years with oscillation around the longterm average. Results of phenological research referred to the interannual variability in dating of phenological phases within the species, also the differences among the species were found.

Quercus dalechampii Ten.) was studied in a submountain beech forest stand in central Slovakia. Two spring phenological phases – bud-burst and leaf unfolding 50% as well as two autumnal phases – leaf discolouration 10% and 50%, respectively were monitored over the period of twenty years (1995–2014). Analysis of the air temperature showed its increasing values mainly in the period from April to August. On the other hand, the values of cumulative rainfall totals for the period from May to August had not clear trend. They were strongly volatile among the years with oscillation around the longterm average. Results of phenological research referred to the interannual variability in dating of phenological phases within the species, also the differences among the species were found. The significant correlations (P < 0.05) were detected between dating of leaf unfolding and air temperature; the coefficients of correlation (r) moved from 0.83 (hornbeam) to 0.90 (oak).

Spol.}, volume = {44}, pages = {7-16}, abstract = {Viacerí, najmä starší členovia dnešnej Slovenskej mykologickej spoločnosti pri SAV si ešte spomenú na rok 1989, kedy sa členovia vtedajšej pracovnej skupiny Základnej organizácie č. 10 Slovenského zväzu ochrancov prírody a krajiny v Bratislave (od roku 1993 Spolok slovenských mykológov, resp. Spoločnosť slovenských mykológov) rozhodli založiť sériu mykologických trvalých výskumných plôch (TVP) v smrekových monokultúrach, rastúcich na bývalej nelesnej pôde na lokalite Vrch Dobroč. Idea dlhodobého monitoringu dynamiky mykocenóz v rôznovekých porastoch pochádza od RNDr. Pavla Lizoňa, PhD., vtedajšieho pracovníka Slovenského národného múzea v Bratislave, dnes pracovníka Botanického ústavu SAV v Bratislave. Pre praktickú realizáciu tejto myšlienky Prof. Ing. Jozef Kodrík, CSc., profesor vtedajšej Vysokej školy lesníckej a drevárskej (dnes Technickej univerzity vo Zvolene), navrhol lokalitu Vrch Dobroč. Spolu s ďalšími poprednými slovenskými mykológmi, Prof. RNDr. Dušanom Mlynarčíkom, DrSc., MUDr. Miloslavom Procházkom, Ing. Vincentom Kabátom, Ing. Pavlom Škublom, CSc., Ľudovítom Varjú, Prof. RNDr. Jánom Gáperom, CSc., na jar v r. 1989 priamo v smrekových porastoch lokality Vrch Dobroč založili štyri TVP o výmere 1250 m2 v porastoch rôzneho veku (TVP A a TVP B v 24-ročných porastoch, TVP C v 7-ročnom poraste a TVP D v 2-ročnej sadenicovej kultúre smreka). Od r. 1989 uvedení mykológovia a niektorí ďalší pracovníci na týchto plochách uskutočnili viacero mykologických exkurzií. Mykofloristický a mykocenologický výskum na mykologických TVP na lokalite Vrch Dobroč bol hlavným cieľom aj kandidátskej dizertačnej práce RNDr. Ivana Mihála, CSc., ktorý na problematike sukcesie a produkcie makromycétov na lokalite Vrch Dobroč intenzívne pracoval v rokoch 1992 až 1994. V ďalších rokoch (1996 až 1999 a v rokoch 2001 a 2003) tento autor na TVP uskutočňoval mykologický výskum spravidla len počas jesenných mesiacov (Mihál 1995, 2002, 2005). Mykologická problematika na lokalite Vrch Dobroč bola predmetom skúmania aj iných autorov, napr. doktorandov z TU Zvolen (Kunca 1997, Kocúrová 1996, 1997, Molnárová 2000 – pozri Gáper, Molnárová 2000 a Šurjanská 2000 – pozri Gáper, Šurjanská 2000). Treba však zdôrazniť, že počas zimy 1993/1994 porasty na lokalite Vrch Dobroč zasiahla silná snehová a vetrová víchrica, čo malo za následok rozsiahlu kalamitu, ktorá postihla aj mykologické TVP (čiastočný rozvrat porastu na TVP A a úplné zničenie porastu na TVP B). Ako náhrada za TVP A a B boli vo vekovo rovnakých porastoch v októbri 1994 vybrané TVP E a TVP F. V ďalších rokoch pokračoval na celej lokalite postupný rozvrat porastov, čo viedlo k sanačným opatreniam lesníckej praxe a po roku 2007 boli zlikvidované porasty aj na TVP C, E a F. Od roku 1989 do roku 2006 je z lokality VDO Vrch Dobroč (priamo z mykologických TVP ako aj mimo výmery TVP) doposiaľ známych 222 druhov makromycétov, ktoré prináležia do 104 rodov. Početnosť determinovaných druhov makromycétov na jednotlivých TVP počas nášho výskumu (od roku 1989 do roku 2003), bola viac-menej rovnaká. Vo veľkej väčšine išlo o bežné a typické druhy pre smrekové porasty. Medzi vzácnejšie nálezy z porastov VDO Vrch Dobroč môžeme zaradiť druhy Anthracobia macrocystis (Cooke) Boud. [podľa Škublu (Škubla 2003) ôsma lokalita na Slovensku], Entoloma lucidum (P. D. Orton) M. M. Moser [podľa Kuncu (Kunca 1996) prvá lokalita na Slovensku], Omphalina scyphiformis (Fr.) Quél. [podľa Škublu (Škubla 2003) druhá lokalita na Slovensku], Stropharia albonitens (Fr.) Quél. [podľa Škublu (Škubla 2003) štvrtá lokalita na Slovensku]. Celkové percentuálne zastúpenie parazitických a saprotrofných lignikolných druhov makromycétov (32,7%), saprotrofných humikolných, karbonikolných a koprofilných druhov (39,2%) a ektomykoríznych - symbiotických druhov makromycétov (28,1%) napovedá, že z ekofyziologického hľadiska môžeme mykocenózu smrekových monokultúr v porastoch TVP charakterizovať ako prevažne saprotrofnú s významným zastúpením ektomykoríznych symbiontov a nízkym zastúpením lignikolných parazitov. Okrem druhovej diverzity bola na mykologických TVP zaznamenávaná aj abundancia plodníc, t.j. početnosť vytvorených epigeických plodníc determinovaných druhov makromycétov na každej TVP. Zo získaných hodnôt abundancie bola následne vypočítaná produkcia biomasy plodníc makromycétov (pomocou hmotnosti priemernej plodnice daného druhu huby). U každého determinovaného druhu bola zaznamenávaná aj distribúcia plodníc, t.j. početnosť miest nálezu plodníc druhu na TVP. Počas výskumu hodnoty abundancie a distribúcie plodníc kolísali tak na jednotlivých TVP ako aj počas jednotlivých rokov hodnotenia, čo môžeme pripísať celkovým klimaticko-ekologickým podmienkam počas jednotlivých rokov (mykologicky chudobné roky 1993, 1997, resp. klimaticky vhodné, mykologicky bohaté roky 1996, 1998, 2001), ako aj pôdnym a humifikačným procesom a klimaticko-ekologickým pomerom, ktoré úzko súvisia aj s vekom porastov. Hodnoty dominancie druhov určovali sukcesný trend makromycétov od najmladších porastov po najstaršie porasty na jednotlivých TVP počas celej doby výskumu. Na TVP A a B boli stálymi dominantami druhy Hygrophorus pustulatus (Pers.) Fr. a Lycoperdon umbrinum Pers., na TVP D sú to druhy Laccaria laccata agg. a Cortinarius cinnamomeus (L.) Fr. V poraste TVP C sa ku konci doby výskumu začali ako dominantné makromycéty uplatňovať najmä druhy rodu Mycena, za účasti stálych dominantov Gymnopus perforans (Hoffm.) Antonín & Noordel., Clitocybe metachroa (Fr.) P. Kumm. alebo Lycoperdon umbrinum. K týmto druhom môžeme priradiť aj ďalšie druhy, ktoré sa v procese sukcesie zaradili do skupiny dominantných makromycétov. Na TVP D sú to druhy Thelephora terrestris Ehrh., Amanita muscaria (L.) Lam. a druhy rodu Mycena. Na TVP C druhy Amanita muscaria, Heyderia abietis (Fr.) Link a Mycena pura (Pers.) P. Kumm. V prípade TVP A a B možno uviesť druhy Gymnopus perforans, Clitocybe metachroa, Paralepista flaccida (Sowerby) Vizzini a Laccaria laccata agg. Do veľkej miery to korešponduje s výsledkami Gápera (Gáper 1992), ktorý v súvislosti s vekom porastu zistil nasledovné sukcesné tendencie: a) druhové spektrum narastá - najmä v rodoch Amanita, Clitocybe, Collybia a Cortinarius, b) druhové spektrum najprv rastie, potom klesá - najmä v rodoch Hebeloma a Marasmius, c) druhové spektrum sa s vekom porastu nemení - najmä v rodoch Chalciporus a Laccaria. Tu treba pripomenúť, že rod Hebeloma sa evidentne najviac vyskytoval na TVP C a iba v malej abundancii na TVP D. Za celú dobu výskumu (1993 až 2003) sme najvyššie hodnoty produkcie biomasy plodníc zaznamenali u druhov Amanita muscaria (1572,2 kg.ha-1 čerstvej hmotnosti plodníc), Lactarius deterrimus Gröger (389,6), Paralepista flaccida (316,4), Lycoperdon umbrinum (305,5), Mycena alcalina agg. (303,2) a Hypholoma fasciculare (Huds.) P. Kumm. (241,7). Najvyššie hodnoty produkcie boli zaznamenané na TVP C (3418,46 kg.ha-1 čerstvej hmotnosti plodníc) a najmenej na TVP B (136,16 kg.ha-1). Je to dané najmä tým, že TVP C predstavovala kompaktný mladý smrekový porast, kde pravidelne a vo veľkej abundancii fruktifikovalo mnoho najmä ektomykoríznych druhov makromycétov, pričom na TVP B boli abundančné a následne aj produkčné hodnoty plodníc všetkých druhov makromycétov veľmi nízke vďaka snehovej a veternej kalamite, ktorá TVP B prakticky zlikvidovala. Nižšie hodnoty produkcie sme z tohto dôvodu zistili aj na TVP A. Perspektívy ďalšieho výskumu Monitoring mykocenóz v rôznovekých smrekových porastoch na VDO Vrch Dobroč bude naisto pokračovať aj počas rokov 2016 až 2019 v rámci doktorandského štúdia a napĺňania cieľov vedeckého projektu VEGA. V máji 2016 boli v rôznovekých smrekových porastoch založené série nových mykologických TVP (A1, A2, A3 – plochy v 15 až 20-ročných porastoch, B1, B2, B3 – plochy v 25 až 30-ročných porastoch a C1, C2, C3 – plochy v 45 až 50-ročných porastoch). Na uvedených nových TVP sa pre najbližšie obdobie v rámci výskumu plánuje pokračovať v hodnotení dynamiky druhovej diverzity makromycétov a vybraných mykocenologických faktorov (abundancia a distribúcia plodníc, dominancia a sukcesia druhov, ekotrofia, produkcia biomasy plodníc). Zároveň sa bude venovať väčšia pozornosť hodnoteniu abiotických faktorov skúmaného prostredia (merania pôdnej vlhkosti, pH, stanovenie štruktúry a zrnitosti pôdy, obsahu biogénnych prvkov, pomeru C/N, množstvo humusu, atď.). Získaná charakteristika pedobiologických a pedochemických pomerov obohatí faktografiu abiotických a biotických pomerov výskumných plôch. Plánuje sa zhodnotiť zdravotný stav smrekových porastov (žltnutie a defoliácia asimilačných orgánov metodikou ICP – Forest) ako aj úroveň fytopatologického ataku porastov (abio – a biotické poškodenia kmeňov smrekov na výskumných plochách). V rámci autekologických pozorovaní sa plánuje výskum fylogenetickej príbuznosti a taxonomickej validity vybraných rodov a druhov makromycétov pomocou molekulárno-genetických metód, t.j. sekvenčnou analýzou klonov nr DNA (napr. rodov Armillaria s.l., Heterobasidion s.l., Laccaria s.l. a Scutellinia s.l.). Na základe predchádzajúceho výskumu z rokov 1989 až 2003 môžeme do určitej miery formulovať pracovné hypotézy, ktorých overenie bude náplňou budúceho výskumu mykoflóry na predmetnom území. Môžeme predpokladať zvýšenie druhovej diverzity a dominancie saprotrofných makromycétov od vekovo najmladších porastov k najstarším smrekovým porastom na jednotlivých TVP. Predpokladáme nárast produkcie biomasy plodníc makromycétov od vekovo najmladších porastov k najstarším smrekovým porastom na jednotlivých TVP, ako aj zvýšenie druhovej diverzity a dominancie lignikolných (parazitických a saprotrofných) makromycétov od vekovo najmladších porastov k najstarším smrekovým porastom. Nakoniec môžeme predpokladať aj pokles druhovej diverzity a dominancie ektomykoríznych makromycétov od vekovo najmladších porastov po vekovo najstaršie porasty na jednotlivých TVP.

Spoločnosť slovenských mykológov) rozhodli založiť sériu mykologických trvalých výskumných plôch (TVP) v smrekových monokultúrach, rastúcich na bývalej nelesnej pôde na lokalite Vrch Dobroč. Idea dlhodobého monitoringu dynamiky mykocenóz v rôznovekých porastoch pochádza od RNDr. Pavla Lizoňa, PhD., vtedajšieho pracovníka Slovenského národného múzea v Bratislave, dnes pracovníka Botanického ústavu SAV v Bratislave. Pre praktickú realizáciu tejto myšlienky Prof. Ing. Jozef Kodrík, CSc., profesor vtedajšej Vysokej školy lesníckej a drevárskej (dnes Technickej univerzity vo Zvolene), navrhol lokalitu Vrch Dobroč. Spolu s ďalšími poprednými slovenskými mykológmi, Prof. RNDr. Dušanom Mlynarčíkom, DrSc., MUDr. Miloslavom Procházkom, Ing. Vincentom Kabátom, Ing. Pavlom Škublom, CSc., Ľudovítom Varjú, Prof. RNDr. Jánom Gáperom, CSc., na jar v r. 1989 priamo v smrekových porastoch lokality Vrch Dobroč založili štyri TVP o výmere 1250 m2 v porastoch rôzneho veku (TVP A a TVP B v 24-ročných porastoch, TVP C v 7-ročnom poraste a TVP D v 2-ročnej sadenicovej kultúre smreka). Od r. 1989 uvedení mykológovia a niektorí ďalší pracovníci na týchto plochách uskutočnili viacero mykologických exkurzií. Mykofloristický a mykocenologický výskum na mykologických TVP na lokalite Vrch Dobroč bol hlavným cieľom aj kandidátskej dizertačnej práce RNDr. Ivana Mihála, CSc., ktorý na problematike sukcesie a produkcie makromycétov na lokalite Vrch Dobroč intenzívne pracoval v rokoch 1992 až 1994. V ďalších rokoch (1996 až 1999 a v rokoch 2001 a 2003) tento autor na TVP uskutočňoval mykologický výskum spravidla len počas jesenných mesiacov (Mihál 1995, 2002, 2005). Mykologická problematika na lokalite Vrch Dobroč bola predmetom skúmania aj iných autorov, napr. doktorandov z TU Zvolen (Kunca 1997, Kocúrová 1996, 1997, Molnárová 2000 – pozri Gáper, Molnárová 2000 a Šurjanská 2000 – pozri Gáper, Šurjanská 2000). Treba však zdôrazniť, že počas zimy 1993/1994 porasty na lokalite Vrch Dobroč zasiahla silná snehová a vetrová víchrica, čo malo za následok rozsiahlu kalamitu, ktorá postihla aj mykologické TVP (čiastočný rozvrat porastu na TVP A a úplné zničenie porastu na TVP B). Ako náhrada za TVP A a B boli vo vekovo rovnakých porastoch v októbri 1994 vybrané TVP E a TVP F. V ďalších rokoch pokračoval na celej lokalite postupný rozvrat porastov, čo viedlo k sanačným opatreniam lesníckej praxe a po roku 2007 boli zlikvidované porasty aj na TVP C, E a F. Od roku 1989 do roku 2006 je z lokality VDO Vrch Dobroč (priamo z mykologických TVP ako aj mimo výmery TVP) doposiaľ známych 222 druhov makromycétov, ktoré prináležia do 104 rodov. Početnosť determinovaných druhov makromycétov na jednotlivých TVP počas nášho výskumu (od roku 1989 do roku 2003), bola viac-menej rovnaká. Vo veľkej väčšine išlo o bežné a typické druhy pre smrekové porasty. Medzi vzácnejšie nálezy z porastov VDO Vrch Dobroč môžeme zaradiť druhy Anthracobia macrocystis (Cooke) Boud. [podľa Škublu (Škubla 2003) ôsma lokalita na Slovensku], Entoloma lucidum (P. D. Orton) M. M. Moser [podľa Kuncu (Kunca 1996) prvá lokalita na Slovensku], Omphalina scyphiformis (Fr.) Quél. [podľa Škublu (Škubla 2003) druhá lokalita na Slovensku], Stropharia albonitens (Fr.) Quél. [podľa Škublu (Škubla 2003) štvrtá lokalita na Slovensku]. Celkové percentuálne zastúpenie parazitických a saprotrofných lignikolných druhov makromycétov (32,7%), saprotrofných humikolných, karbonikolných a koprofilných druhov (39,2%) a ektomykoríznych - symbiotických druhov makromycétov (28,1%) napovedá, že z ekofyziologického hľadiska môžeme mykocenózu smrekových monokultúr v porastoch TVP charakterizovať ako prevažne saprotrofnú s významným zastúpením ektomykoríznych symbiontov a nízkym zastúpením lignikolných parazitov. Okrem druhovej diverzity bola na mykologických TVP zaznamenávaná aj abundancia plodníc, t.j. početnosť vytvorených epigeických plodníc determinovaných druhov makromycétov na každej TVP. Zo získaných hodnôt abundancie bola následne vypočítaná produkcia biomasy plodníc makromycétov (pomocou hmotnosti priemernej plodnice daného druhu huby). U každého determinovaného druhu bola zaznamenávaná aj distribúcia plodníc, t.j. početnosť miest nálezu plodníc druhu na TVP. Počas výskumu hodnoty abundancie a distribúcie plodníc kolísali tak na jednotlivých TVP ako aj počas jednotlivých rokov hodnotenia, čo môžeme pripísať celkovým klimaticko-ekologickým podmienkam počas jednotlivých rokov (mykologicky chudobné roky 1993, 1997, resp. klimaticky vhodné, mykologicky bohaté roky 1996, 1998, 2001), ako aj pôdnym a humifikačným procesom a klimaticko-ekologickým pomerom, ktoré úzko súvisia aj s vekom porastov. Hodnoty dominancie druhov určovali sukcesný trend makromycétov od najmladších porastov po najstaršie porasty na jednotlivých TVP počas celej doby výskumu. Na TVP A a B boli stálymi dominantami druhy Hygrophorus pustulatus (Pers.) Fr. a Lycoperdon umbrinum Pers., na TVP D sú to druhy Laccaria laccata agg. a Cortinarius cinnamomeus (L.) Fr. V poraste TVP C sa ku konci doby výskumu začali ako dominantné makromycéty uplatňovať najmä druhy rodu Mycena, za účasti stálych dominantov Gymnopus perforans (Hoffm.) Antonín & Noordel., Clitocybe metachroa (Fr.) P. Kumm. alebo Lycoperdon umbrinum. K týmto druhom môžeme priradiť aj ďalšie druhy, ktoré sa v procese sukcesie zaradili do skupiny dominantných makromycétov. Na TVP D sú to druhy Thelephora terrestris Ehrh., Amanita muscaria (L.) Lam. a druhy rodu Mycena. Na TVP C druhy Amanita muscaria, Heyderia abietis (Fr.) Link a Mycena pura (Pers.) P. Kumm. V prípade TVP A a B možno uviesť druhy Gymnopus perforans, Clitocybe metachroa, Paralepista flaccida (Sowerby) Vizzini a Laccaria laccata agg. Do veľkej miery to korešponduje s výsledkami Gápera (Gáper 1992), ktorý v súvislosti s vekom porastu zistil nasledovné sukcesné tendencie: a) druhové spektrum narastá - najmä v rodoch Amanita, Clitocybe, Collybia a Cortinarius, b) druhové spektrum najprv rastie, potom klesá - najmä v rodoch Hebeloma a Marasmius, c) druhové spektrum sa s vekom porastu nemení - najmä v rodoch Chalciporus a Laccaria. Tu treba pripomenúť, že rod Hebeloma sa evidentne najviac vyskytoval na TVP C a iba v malej abundancii na TVP D. Za celú dobu výskumu (1993 až 2003) sme najvyššie hodnoty produkcie biomasy plodníc zaznamenali u druhov Amanita muscaria (1572,2 kg.ha-1 čerstvej hmotnosti plodníc), Lactarius deterrimus Gröger (389,6), Paralepista flaccida (316,4), Lycoperdon umbrinum (305,5), Mycena alcalina agg. (303,2) a Hypholoma fasciculare (Huds.) P. Kumm. (241,7). Najvyššie hodnoty produkcie boli zaznamenané na TVP C (3418,46 kg.ha-1 čerstvej hmotnosti plodníc) a najmenej na TVP B (136,16 kg.ha-1). Je to dané najmä tým, že TVP C predstavovala kompaktný mladý smrekový porast, kde pravidelne a vo veľkej abundancii fruktifikovalo mnoho najmä ektomykoríznych druhov makromycétov, pričom na TVP B boli abundančné a následne aj produkčné hodnoty plodníc všetkých druhov makromycétov veľmi nízke vďaka snehovej a veternej kalamite, ktorá TVP B prakticky zlikvidovala. Nižšie hodnoty produkcie sme z tohto dôvodu zistili aj na TVP A. Perspektívy ďalšieho výskumu Monitoring mykocenóz v rôznovekých smrekových porastoch na VDO Vrch Dobroč bude naisto pokračovať aj počas rokov 2016 až 2019 v rámci doktorandského štúdia a napĺňania cieľov vedeckého projektu VEGA. V máji 2016 boli v rôznovekých smrekových porastoch založené série nových mykologických TVP (A1, A2, A3 – plochy v 15 až 20-ročných porastoch, B1, B2, B3 – plochy v 25 až 30-ročných porastoch a C1, C2, C3 – plochy v 45 až 50-ročných porastoch). Na uvedených nových TVP sa pre najbližšie obdobie v rámci výskumu plánuje pokračovať v hodnotení dynamiky druhovej diverzity makromycétov a vybraných mykocenologických faktorov (abundancia a distribúcia plodníc, dominancia a sukcesia druhov, ekotrofia, produkcia biomasy plodníc). Zároveň sa bude venovať väčšia pozornosť hodnoteniu abiotických faktorov skúmaného prostredia (merania pôdnej vlhkosti, pH, stanovenie štruktúry a zrnitosti pôdy, obsahu biogénnych prvkov, pomeru C/N, množstvo humusu, atď.). Získaná charakteristika pedobiologických a pedochemických pomerov obohatí faktografiu abiotických a biotických pomerov výskumných plôch. Plánuje sa zhodnotiť zdravotný stav smrekových porastov (žltnutie a defoliácia asimilačných orgánov metodikou ICP – Forest) ako aj úroveň fytopatologického ataku porastov (abio – a biotické poškodenia kmeňov smrekov na výskumných plochách). V rámci autekologických pozorovaní sa plánuje výskum fylogenetickej príbuznosti a taxonomickej validity vybraných rodov a druhov makromycétov pomocou molekulárno-genetických metód, t.j. sekvenčnou analýzou klonov nr DNA (napr. rodov Armillaria s.l., Heterobasidion s.l., Laccaria s.l. a Scutellinia s.l.). Na základe predchádzajúceho výskumu z rokov 1989 až 2003 môžeme do určitej miery formulovať pracovné hypotézy, ktorých overenie bude náplňou budúceho výskumu mykoflóry na predmetnom území. Môžeme predpokladať zvýšenie druhovej diverzity a dominancie saprotrofných makromycétov od vekovo najmladších porastov k najstarším smrekovým porastom na jednotlivých TVP. Predpokladáme nárast produkcie biomasy plodníc makromycétov od vekovo najmladších porastov k najstarším smrekovým porastom na jednotlivých TVP, ako aj zvýšenie druhovej diverzity a dominancie lignikolných (parazitických a saprotrofných) makromycétov od vekovo najmladších porastov k najstarším smrekovým porastom. Nakoniec môžeme predpokladať aj pokles druhovej diverzity a dominancie ektomykoríznych makromycétov od vekovo najmladších porastov po vekovo najstaršie porasty na jednotlivých TVP.

At present, its activity in Slovakia was discovered in the winter months. It also extends to higher altitudes. Therefore it is necessary to know the ecology and optimal conditions suitable for its existence. Although considerable attention is devoted to the health research of tick, little is known about its claim on the soil environment, because as a representative of a temporary edaphone initial ontogenetic stages (eggs and larvae) survives in the soil. For this reason, the research focused on the soil pH as an important environmental factor that can influence the development and abundance of tick. The research was carried out on the plots with tick high abundance in the Veľká Fatra Mts at an altitude of - 760 meters asl. We found that mull humus form with a thin film of last year’s litter fall (the Oon necrotic subhorizon) with a pH narrow range of 5.9–6.0 (rounded) was convenient for developmental stages of this tick. Below this horizon the soil type of cambisol with pH values in the upper range of 5.45–5.79 was produced. The soil reaction was therefore a slight acid. In this environment, a relatively high density of tick was in May, with the secondary mild autumn peak.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Tick Ixodes ricinus is a carrier of several diseases.

Although considerable attention is devoted to the health research of tick, little is known about its claim on the soil environment, because as a representative of a temporary edaphone initial ontogenetic stages (eggs and larvae) survives in the soil. For this reason, the research focused on the soil pH as an important environmental factor that can influence the development and abundance of tick. The research was carried out on the plots with tick high abundance in the Veľká Fatra Mts at an altitude of - 760 meters asl. We found that mull humus form with a thin film of last year’s litter fall (the Oon necrotic subhorizon) with a pH narrow range of 5.9–6.0 (rounded) was convenient for developmental stages of this tick. Below this horizon the soil type of cambisol with pH values in the upper range of 5.45–5.79 was produced. The soil reaction was therefore a slight acid. In this environment, a relatively high density of tick was in May, with the secondary mild autumn peak. |

Aims: To define territorial borders that exist within a nuthatch population and to compare densities of trees and cavities between used and non-used parts of their available habitat in order to determine habitat preferences. Methods: The number and location of territories was estimated by mapping the individual positions of colour-ringed birds. We measured habitat characteristics in regular sampling grid (number of trees and number of cavities per 50×50 m) during three successive seasons and modelled probability of occurrence of nuthatch territories in the area. Results: Breeding pairs were observed to defend territories of median size between 1.46 and 2.93 ha. These sizes correspond well to high-quality habitat territories for this species. We found that pairs tended to occupy territories with higher densities of trees and cavities. Based on generalized linear mixed-effects model estimates, we found that in pastured oak woodland habitat with density of 60 trees per ha, the estimated probability of occurrence (with 95% confidence interval) of a nuthatch territory was about 96% (83−99). For cavity density, the probability of territory occurrence was about 74% (52−89) at the level of 60 cavities per ha.

The spatial analysis of molecular variance identified three geographically homogenous genetic clusters (one in Slovakia and two in Romania) with a high level of differentiation among them, suggesting restricted gene flow, whilst Bayesian skyline simulation reconstructed a negative demographic change through evolutionary time. Inferred genetic pattern clearly coincides with differences in males’ colour phenotype as the extent of pigmentation on the lateral pronotum varied significantly among genetic lineages. We suggest that geographical variation in the species populations has relict-like character and their isolated occurrence is not a result of recent introduction events. Identification of ‘evolutionary units’ may help in the conservation and management of this rare insect species. |

More than half of the explained variation was shared among four sets of variables in SE, contrary to CE. Except to U trees in SE, the effect of climate – pure or spatially structured – remained the highest also after partitioning of variance; more in SE than in CE.

We found a large variability in percentage of leaves longer than 70 mm (16–58%) and those of dark-green colour (28–78%), portion of half-full flowers (0–6%) and those of intense pink colour (0–100%), and percentage of hips longer than 20 mm (0–45%) and those of intense red colour (18–48%), among shrubs.

Caninae) from Malé Karpaty mountains (localities Modra – Pažite and Vrbové – Baraní dvor) and Zobor hills (locality Zobor – Lyžiarska lúka) were analysed. We found a large variability in percentage of leaves longer than 70 mm (16–58%) and those of dark-green colour (28–78%), portion of half-full flowers (0–6%) and those of intense pink colour (0–100%), and percentage of hips longer than 20 mm (0–45%) and those of intense red colour (18–48%), among shrubs.
