“…Dry grasslands can be emphasized within this group (Janišová et al, 2011) because of their high importance in biodiversity conservation in Hungary (Kun, 1998;Valkó et al, 2013a). Grasslands evolved with herbivores, burrowing animals and experienced recurrent fire and adapted to natural disturbances by various life forms and plant behavioural types (Knapp et al, 1998;Strauss and Agrawal, 1999;Gibson, 2009, Valkó et al, 2013b.…”

Our aim was to investigate the species richness and diversity of a loess grassland influenced by the digging of the lesser blind mole rat [Nannospalax (superspecies leucodon)] and to study the effect of this disturbance to diversity. The study was conducted in the Külső-gulya loess grassland (Körös-Maros National Park), which is unique in Hungary due to its excellent soil quality and the large spatial extent of natural loess meadow steppe. We recorded the cover of species in 50x50 cm plots. Altogether 12 plots were sampled on mounds of mole rat and 12 plots as a control in the area with no mounds. Differences in species richness, Shannondiversity, evenness and total cover between disturbed and control plots were tested by One-Way ANOVA. There were no significant difference neither in the number of species, nor in the Shannondiversity and evenness. There were differences in the species composition detected by PCO ordination. We can conclude that the presence and disturbance of the mole rat influence the composition of the grassland significantly but it does not cause a difference in the species richness, diversity and total cover. Our results suggest that this grassland has adapted to these natural disturbances.

Palaearctic grasslands encompass a diverse variety of habitats, many of high nature value and vulnerability. The main challenges are climate-change, land-use change, agricultural intensification and abandonment. Many measures are in place to address these challenges, through restoration and appropriate management, though more work is necessary. We present eight studies from China/Germany, Greece, Kazakhstan, Russia and Ukraine. The papers cover a wide range of grassland and steppe habitats and cover vegetation ecology, syntaxonomy and zoology. We also conducted a systematic search on steppe and grassland diversity. The greatest number of studies was from China, followed by Germany and England. We conclude that the amount of research being carried out on Eurasian grasslands is inadequate considering their high levels of biodiversity and vulnerability. We hope to encourage readers to address current major challenges, such as how to manage grasslands for the benefit of diverse taxa, to ensure that conservation initiatives concentrate on sites where there is good potential for success and for the generation of realistic and viable conservation strategies. IzvlečekTravišča zmerne palearktične regije predstavljajo raznolika življenjska okolja, med katerimi so številna naravovarstveno pomembna in ogrožena. Glavni izzivi, kot so klimatske spremembe, spremembe rabe tal, intenzifikacija kmetijstva in opušča-nje rabe, so znani. Nanje skušamo odgovoriti z različnimi ukrepi, z obnovo in primernim gospodarjenjem s travišči, vendar bo potrebno še veliko postoriti. V tej številki predstavljamo osem raziskav travišč na Kitajskem in v Nemčiji, Grčiji, Kazahstanu, Rusiji in Ukrajini. Članki pokrivajo širok izbor travišč in stepskih habitatov in predstavljajo vegetacijsko ekološke, sintaksonomske in zoološke vidike. Naredili smo tudi sistematično poizvedbo o člankih s tematiko raznolikosti step in travišč. Največje število raziskav je s Kitajske, sledita Nemčija in Anglija. Zaključimo lahko, da je število raziskav evrazijskih travišč nezadostno, če upoštevamo njihovo veliko raznolikost in ogroženost zaradi okoljskih sprememb. Upamo, da bo ta posebna številka vzpodbudila bralce, da se bodo usmerili v raziskave glavnih izzivov, na primer kako gospodariti na rastiščih v prid različnim vrstam, da se bodo naravovarstvene pobude osredotočile na rastišča z dobrim potencialom za uspeh ali za izdelavo nove generacije realnih in izvedljivih strategij ohranjanja.

“…Most of them evolved under the combined effects of environmental conditions and traditional land use (Janisová et al, 2011). Although in the past xerophytic grasslands had a great extension in the temperate regions of Europe, particularly in the eastern and central parts of the continent, the change in the land use, intensification and expansion of agriculture practices led to their large scale fragmentation (Zulka et al, 2014).…”

Abstract. Dry grasslands are plant communities with major importance for biodiversity. In this study, xeric grasslands of the order Festucetalia valesiacae from North-Eastern Romania were analyzed, in 45 nested series, at seven grain sizes (0.0001-100 m 2 ), sampled in 5 plant communities within above mentioned phytosociological unit. The aim was to test the relative importance of different environmental factors on species richness (α-diversity) and species turnover (β-diversity), the last one expressed as the exponent of the power-law species-area relationship, and to detect which is the influence of spatial scale on diversity-environment relationship. Generalized linear models were used to assess the relative importance of predictors in shaping diversity in all seven spatial scales. The results showed that diversityenvironment relationships were dependent on the scale of analysis, different factors being influential at different spatial scales. Local environmental conditions and land use practices were more related to species richness while general soil characteristics explained a larger proportion of spatial species turnover. In conclusion, diversity-environment relationships in the xeric grasslands from North-Eastern Romania are scale dependent, with local factors more important at small spatial scales and soil parameters more important for larger scales.
