Megjegyzések:Steppe is among the most endangered biomes of the world, especially in Eastern Europe, where more than 90 % of original steppes have been destroyed due to conversion into croplands, afforestation and other human activities. Currently, steppe vegetation is often restricted to places unsuitable for ploughing, such as ancient burial mounds called kurgans. The aim of our study was to collect and synthesise existing knowledge on kurgans by a review of research papers and grey literature. The proportion of kurgans covered by steppe vegetation increases from west to east and from lowlands to uplands. Despite their small size, kurgans act as biodiversity hotspots and harbour many red-listed species. High overall species richness and a high proportion of grassland specialists are maintained by a pronounced fine-scale environmental heterogeneity. The main factors threatening the biodiversity of kurgans are intensified agriculture and construction works. We conclude that kurgans can play a crucial role in preserving steppe vegetation, especially in intensively used agricultural landscapes in the western part of the steppe zone. Despite the vital role of kurgans in sustaining steppe vegetation, we identified serious knowledge gaps on their distribution, vegetation, flora and fauna and their potential role in steppe restoration.

Cím:European grassland ecosystems : threatened hotspots of biodiversity / Jan Christian Habel, Jürgen Dengler, Monika Janišová, Péter Török, Camilla Wellstein, Michal Wiezik
Dátum:2013
ISSN:0960-3115 1572-9710
Megjegyzések:Biodiversity is not homogenously distributed over the globe, and ecosystems differ strongly in the number of species they provide. With this special issue we highlight the ecology and endangerment of one of the most diverse ecosystem of Europe: the European grassland ecosystems. The selected 16 contributions describe interactions from below-ground to the atmosphere and focus on (1) effects of abiotic and biotic on species diversity, (2) the impact of various factors along spatial and temporal gradients, (3) the relevance of falling abandoned and eutrophication-including countervailing management strategies like encroachment; and (4) intraspecific effects based on physiology, genetics and intraspecific plasticity. The contributions cover fungi, plants, and invertebrates and highlight effects taking place at the level of ecosystem, species community, species, populations, and also within individuals (physiology and genetics).

Cím:Integrating ongoing biodiversity monitoring: potential benefits and methods / Pierre-Yves Henry, Szabolcs Lengyel, Piotr Nowicki, Romain Julliard, Jean Clobert, Tatjana Čelik, Bernd Gruber, Dirk S. Schmeller, Valerija Babij, Klaus Henle
Dátum:2008
Megjegyzések:Halting the loss of biodiversity comes along with the need to quantify biodiversity composition and dynamics at large spatial and temporal scales. Highly standardized, international monitoring networks would be ideal, but they do not exist yet. If we are to assess changes in biodiversity now, combining output available from ongoing monitoring initiatives is the only option. However, integration of biodiversity information across schemes is still very poorly developed. In this paper, we outline practical issues to be considered when planning to combine existing monitoring information. First, we provide an overview of avenues for integration along the four dimensions that characterize a monitoring design: sample size, biological coverage, spatial coverage and temporal coverage. We also emphasize that complementarity in monitoring targets across schemes enables to describe complex processes of biodiversity dynamics, e.g. through relating species traits to the impacts of environmental changes. Second, we review some methods to overcome differences in designs among monitoring schemes, such as site selection, poststratification and measurement error. Finally, we point out some commonly used statistical methods that are at hand for combining data or parameter estimates. We especially emphasize the possible levels of data integration (raw data, parameter estimates, or effect size estimates), and the largely under-exploited potential of meta-analysis methods and weighted analyses. This contribution aims to bolster the practice and use of integration of ongoing monitoring initiatives for biodiversity assessment.

Cím:Both local and landscape-level factors are important drivers in shaping ground-dwelling spider assemblages of sandy grasslands / Horváth Roland, Magura Tibor, Tóthmérész Béla, Eichardt János, Szinetár Csaba
Dátum:2019
ISSN:0960-3115
Megjegyzések:Earlier studies emphasized that landscape-level factors were essential in shaping arthropod assemblages of semi-natural grasslands. Recently, several studies demonstrated that local factors were more important than landscape-level factors. We examined the importance of several local and landscape-level factors on spider assemblages using pitfall traps from eight sandy grassland fragments between 2001 and 2003. We tested three hypotheses: (i) species richness decreases with grazing intensity; (ii) species richness increasing with fragment size; (iii) the higher isolation of fragments results in decreasing species richness. We found that species richness of spiders did not depend on the grazing intensity, but there were changes in species composition and abundance of species among the variously grazed fragments. Out of the other two studied local factors (fragment size, and the shape of fragment), only the fragment size was a significant predictor of the diversity of specialist spiders, since the number of these species increased significantly with fragment size. Out of the four investigated landscape-level factors (isolation, total area of croplands in the landscape, total area of forests in the landscape, and landscape diversity), only the isolation was a significant predictor influencing spider diversity. The total number of species, the number of generalist species and the number of hunting species increased significantly with the isolation of fragments. Our results suggest that both local and landscape-level factors are important drivers in maintaining spider diversity in sandy grasslands; therefore, these factors should be considered simultaneously during the restoration and/or management of grasslands.

Cím:Large and least isolated fragments preserve habitat specialist spiders best in dry sandy grasslands in Hungary / Roland Horváth, Tibor Magura, Csaba Szinetár, János Eichardt, Béla Tóthmérész
Dátum:2013
ISSN:0960-3115
Megjegyzések:The role of fragment size, isolation and habitat diversity in the conservation ofspider assemblages living in fragmented landscape were studied in dry sandy grasslands(East Hungary, Nyírség). Spiders were collected using pitfall traps at eight dry grasslandfragments from 2001 to 2009 from March to October fortnightly. We tested the rules ofisland biogeography, which suggest that the species richness increases with the size anddecreases with the isolation of fragments. The habitat diversity is an important factor forspecies richness, since large areas usually have more habitats; therefore, the number ofspecies may be higher in these areas. During the 9-year study period, altogether 10,544individuals belonging to 106 species were collected. Contradicting the classical theory, wefound a significant negative relationship between the total number of spider species and thegrassland size, while the ratio of sandy grassland specialist spider species increased withfragment size. The relationship between the ratio of generalist species and the fragmentsize was not significant. The overall species richness and the isolation of studied grasslandsdid not show a significant relationship. The ratio of sandy grassland specialist speciesdecreased, while the ratio of generalist species increased with the increasing of isolation.The habitat diversity did not show any effect on spider species richness. We concluded thatto conserve the habitat specialist species it is recommended to preserve the large and leastisolated grassland fragments, furthermore to increase the size of small fragments with therestoration of the adjacent croplands.

Cím:Phylogeographic patterns of steppe species in Eastern Central Europe: a review and the implications for conservation / Łukasz Kajtoch, Elżbieta Cieślak, Zoltán Varga, Wojciech Paul, Miłosz A. Mazur, Gábor Sramkó, Daniel Kubisz
Dátum:2016
ISSN:0960-3115 1572-9710
Megjegyzések:The phylogeography of species associated with European steppes and extrazonal xeric grasslands is poorly understood. This paper summarizes the results of recent studies on the phylogeography and conservation genetics of animals (20 taxa of beetles, butterflies, reptiles and rodents) and flowering plants (18 taxa) of such, "steppic" habitats in Eastern Central Europe. Most species show a similar phylogeographic pattern: relatively high genetic similarity within regional groups of populations and moderate-to-high genetic distinctiveness of populations from currently isolated regions located in the studied area. This distinctiveness of populations suggests a survival here during glacial maxima, including areas north of the Bohemian Massif-Carpathians arc. Steppic species generally do not follow the paradigmatic patterns known for temperate biota (south-north "contraction?expansion"), but to some extent are similar to those of arctic-alpine taxa. There are three main groups of taxa within Eastern Central Europe that differ in their contemporary distribution pattern, which may reflect historical origin and expansion routes. Present diversity patterns of the studied steppic species suggest that they share a unique genetic signature and distinct assemblages exist in each of the now isolated areas rich in steppic habitats. At least some of these areas probably act as present "interglacial refugia" for steppic species. This study strongly supports the need to protect steppic species throughout their entire ranges in the region, as the continuous destruction of steppic habitats in some areas may lead not only to the disappearance of local populations, but also to the extinction of unique evolutionary units.

Cím:Sustaining recovered grasslands is not likely without proper management: vegetation changes after cessation of mowing / András Kelemen, Péter Török, Orsolya Valkó, Balázs Deák, Tamás Miglécz, Katalin Tóth, Tamás Ölvedi, Béla Tóthmérész
Dátum:2014

Megjegyzések:Grasslands recovered by sowing low diversity seed mixtures of local provenanceare usually managed by mowing. Besides restoration success only a few studies havefocused on the direct effects of post-restoration mowing on recovered grassland vegetation.In this study we followed vegetation changes in 13 successfully recovered grasslands in5 9 5-m-sized sites with continuous and ceased mowing at Hortoba?gy National Park, East-Hungary. We asked the following questions: (i) What are the effects of cessation ofmowing on the vegetation structure and diversity of recovered grasslands? (ii) What are theeffects of cessation of mowing on the abundance of sown grasses, target and undesirablespecies? (iii) Is yearly mowing an appropriate management tool for the maintenance ofrecovered grasslands? Our results showed that the cessation of mowing caused litteraccumulation, while diversity, total vegetation cover and the cover of sown grassesdecreased compared to the mown sites. The cover of undesirable perennial species wassignificantly higher in unmown sites than in mown ones. The species composition of mownsites remained more similar to near-natural grasslands than the unmown ones. Our resultssuggest that without regular post-restoration mowing the favourable status of recoveredgrasslands can rapidly decline due to litter accumulation and by the expansion of undesirablespecies, even in the short-run. We also stress that while yearly mowing is enough tomaintain grasslands recovered by low-diversity seed sowing, it cannot be considered to beenough to recover target vegetation composition.

Cím:A review and a framework for the integration of biodiversity monitoring at the habitat level / Szabolcs Lengyel, Andrej Kobler, Lado Kutnar, Erik Framstad, Pierre-Yves Henry, Valerija Babij, Bernd Gruber, Dirk Schmeller, Klaus Henle
Dátum:2008
Megjegyzések:The monitoring of biodiversity at the level of habitats is becoming widespread in Europe and elsewhere as countries establish national habitat monitoring systems and various organisations initiate regional and local schemes. Parallel to this growth, it is increasingly important to address biodiversity changes on large spatial (e.g. continental) and temporal (e.g. decade-long) scales, which requires the integration of currently ongoing monitoring efforts. Here we review habitat monitoring and develop a framework for integrating data or activities across habitat monitoring schemes. We first identify three basic properties of monitoring activities: spatial aspect (explicitly spatial vs. non-spatial), documentation of spatial variation (field mapping vs. remote sensing) and coverage of habitats (all habitats or specific habitats in an area), and six classes of monitoring schemes based on these properties. Then we explore tasks essential for integrating schemes both within and across the major classes. Finally, we evaluate the need and potential for integration of currently existing schemes by drawing on data collected on European habitat monitoring in the EuMon project. Our results suggest a dire need for integration if we are to measure biodiversity changes across large spatial and temporal scales regarding the 2010 target and beyond. We also make recommendations for an integrated pan-European habitat monitoring scheme. Such a scheme should be based on remote sensing to record changes in land cover and habitat types over large scales, with complementary field mapping using unified methodology to provide ground truthing and to monitor small-scale changes, at least in habitat types of conservation importance.

Cím:Forest edge and diversity: carabids along / Magura Tibor, Tóthmérész Béla, Molnár Tivadar
Dátum:2001
ISSN:0960-3115 1572-9710
Megjegyzések:Diversity relationships of carabids in forest edges and the neighbouring forest interior and the surrounding grassland are studied. Samples were taken along three replicated forest-grassland transects using pitfall traps in the Aggtelek National Park in Hungary during 2 years. The study revealed significant edge effect on the carabids. The Shannon diversity of carabids were significantly higher in the forest edge and the grassland than in the forest interior. Carabids of the forest interior, forest edge and grassland can be separated from each other by ordinations, both on the species composition and abundance, suggesting that all three habitats have a distinct species assemblage. Moreover, indicator species analysis detected significant edge associated species; based on the specificity and fidelity of the carabids we have distinguished five groups of species: habitat generalists, grassland-associated species, forest generalists, forest specialists, and edge-associated species. Multiple linear regression analyses showed that relative air moisture, temperature of the ground and cover of the herbs are the most important factors determining the diversity of carabids along the transects. Our results show that the high diversity of carabids in forest edges is due to the edge-associated species and the presence of species characteristic to the adjacent habitats. The significance of forest edges in nature conservation, serving as a source habitat for dispersal processes, contributing to the recolonization of carabids after habitat destruction or other disturbance is emphasized.

Cím:Impacts of Leaf-litter Addition on Carabids in a Conifer Plantation / Magura Tibor, Tóthmérész Béla, Elek Zoltán
Dátum:2005
ISSN:0960-3115 1572-9710
Megjegyzések:As a ?ne-scale, manipulative model experiment leaf litter was added in plots to increase habitat heterogeneity in a 50-year-old Norway spruce plantation, established after the clear-cutting of a native beech forest, during a 2-year period in the Hungarian Mountain Range. Pitfall trap catches of carabids from leaf-litter plots were compared with those from control plots to explore the effect of leaf-litter addition. Difference in the species composition was revealed by ordination; scores of the samples of the two plot types were signi?cantly separated along the ?rst MDS axis. The most numerous species (Pterostichus oblongopunctatus) was signi?cantly more abundant in the leaf-litter plots. However, there were no signi?cant differences for the other most frequently obtained species. Habitat generalist species were the most abundant, followed by forest generalists, then forest specialists, and there were some open habitat species. Enhanced habitat heterogeneity (leaf-litter addition) in homogeneous plantations in?uenced the spatial distribution and composition of carabids, through altered abiotic (lower ground temperature inthe leaf-litter plots) and biotic (more prey items) factors. Differencesinabundance,speciesrichnessandShannondiversitywerenotsigni?cantbetween the control and the manipulated plots, although carabidcatch was higher inthe leaf-litterplots during both years. Forestry practices to increase habitat heterogeneity should be considered to enhance biodiversity in managed forests.
