Grassland monitoring in juniper-poplar forests
Fire is one of the most important human disturbance in Homokhátság and its impact is increasing due to climate change. We monitor the long term post-fire regeneration of grasslands in juniper-poplar forests in two sites (Bugac and Orgovány) in four stands respectively. We sample 10 grassland patches in every stand with five 1x1 m quadrat in each patch. The sampling has been conducted twice a year since 1997 in Bugac and 2002 in Orgovány. This dataset is the longest among the yearly sampled biodiversity datasets of KISKUN LTER.
Traits for understanding plant community assembly: a new theoretical framework and testing with field data
The aim of the project is to study of community assembly within a trait-based theoretical framework. Two theories are considered: habitat filtering and limiting similarity. Habitat filtering means that the species traits are filtered by habitat conditions (e.g. soil properties) and disturbance regime. Not only the occurrence of filtering will be tested, but also the range of trait values before and after filtering will be measured. According to the limiting similarity principle, co-existing species have to differ in traits related to regulating factors.
(A növényzet-alapú természeti tőke index)
Az emberiség legtöbb tevékenysége meghatározó befolyást gyakorol a környező táj természetes élővilágára. A mindennapi életben sokszor kényszerülünk a táj állapotát befolyásoló döntések meghozatalára. Az elmúlt évtizedekben világszerte felerősödtek a törekvések olyan könnyen értelmezhető mérőszámok kifejlesztésére, melyek szakmailag megalapozott értékelést tudnak nyújtani az élővilág állapotáról a nagyközönség és a döntéshozók számára. Nemzetközi szinten számos durva léptékű, elsősorban globális szinten használható aggregált biodiverzitás-indikátor került kifejlesztésre.

Interactions between natural and human-dominated ecosystems: biodiversity, ecosystem functions and land-use in the Great Hungarian Plain
The Great Hungarian Plain is characterised by both unique natural values and intensive land-use. The on-going and future land-use changes may considerably affect ecological integrity, thus a further decline in biodiversity can only be avoided if nature conservation and socio-economic priorities are considered together. The overall objective of the proposed research is to assess the relationships between land-use, biodiversity and ecosystem functioning.
