Long-term development of different grassland insect communities in Central Europe since the 1950s
(2011-09-13)Central European landscape considerably changed during the second half of the 20th century. These changes are probably mainly caused by modern agriculture. Today, Central Europe consists ... -
The impact of ants on the aboveground and belowground ecological network - field studies in a grassland and experiments with microcosms
(2011-03-15)In this work, two areas of ants` functioning in ecosystem were studied. On the one hand, I investigated how ants affect the aboveground system by acting as mutualistic partners and predators ... -
Diversity and trophic structure of the soil fauna and its influence on litter decomposition in deciduous forests with increasing tree species diversity
(2009-09-29)The relationship between species diversity and ecosystem function is an important topic of modern ecological research. Plant diversity has often been found to affect structural and ... -
Ants and spiders in grassland food webs
(2008-08-29)A challenge in ecology is to uncover the link between food web interactions and ecosystem function. Recent studies have shown that top-down forces by invertebrate predators on their prey ... -

Ameisen als Schlüsseltiergruppe in einem Grasland
(2004-10-28)Ants as eusocial predators living in the soil and ground litter are able to directly or indirectly affect soil organisms, herbivores and plants via trophic interactions ("top-down") and ... -
Wechselwirkung zwischen Schwarzerlen und Erlenblattkäfer: Signaltransfer zwischen Bäumen und induzierte Resistenz
(2002-01-23)The presented work investigates the hypothesis of interplant communication between trees. According to this hypothesis, damaged plants release airborne chemical signals which can induce ...
