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: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:Step(pe) up! Raising the profile of the Palaearctic natural grasslands / Péter Török, Didem Ambarli, Johannes Kamp, Karsten Wesche, Jürgen Dengler
Dátum:2016
ISSN:0960-3115 1572-9710
Megjegyzések:Palaearctic steppes are primary grasslands dominating the landscape of the Eurasian Grassland Belt from Central and Eastern Europe to Northern China across the temperate zone of Eurasia. We also include structurally and floristically similar habitats in North Africa, Anatolia, and Iran. The biota of the steppes are diverse, including many endemic species. As a result of the high rate of anthropogenic conversion and widespread degradation, the Palaearctic steppes have become one of the most endangered terrestrial biomes of the world. These facts underline the importance of sustaining landscape-scale biodiversity in steppes and stress the necessity of their conservation and restoration. Literature about the ecology, biodiversity, and conservation of Palaearctic steppes is not easily accessible for an international audience. Therefore, summarising the current state of knowledge as well as knowledge gaps is very timely. This Special Issue on "Palaearctic steppes: ecology, biodiversity and conservation", comprises 17 research papers from many different regions throughout the biome, as well as a broad review synthesising current knowledge.

Cím:The Palaearctic steppe biome : a new synthesis / Karsten Wesche, Didem Ambarli, Johannes Kamp, Peter Török, Jan Treiber, Jürgen Dengler

Megjegyzések:The Palaearctic steppes range from the Mediterranean basin towards China, forming one of the largest continuous terrestrial biomes. The literature on steppe ecology and conservation is vast but scattered and often not available in English. We provide a review of some key topics based on a new definition of steppes, which includes also Mediterranean steppes and alpine rangelands of the Asian Highlands. Revisiting the terrestrial ecoregions of the world, we estimate that the Palaearctic steppe biome extends over ca. 10.5 million km2. Major chorological regions differ in their macroclimatic niche with a clear distinction between Middle Asia with its winter precipitation and the Central Asian summer-rain regions of the Mongolian plateau and of Tibet. Steppe soils store large amounts of carbon, yet the sequestration potential is debated and depends on land use. Major physiognomic-ecological steppe types include forest-, typical-, desert-, and alpine-steppe, which vary in the importance of grasses, mainly C3 species. The steppes host a specialised fauna, and Middle Asia, Tibet, and especially Mongolia, have large herds of migrating ungulates. The share of pristine and protected sites is low in the steppe regions, with conversion into croplands being the most important land use impact in Europe, Middle Asia, and the Mediterranean, while grazing has a severe impact in some parts of Mongolia and Tibet. There are major gaps in our knowledge on: (1) the effects of climate change on the crucial seasonal patterns; (2) the role of steppe soils in the global carbon budget; and (3) the ecology and distribution of most animal groups except vertebrates.
