Soil fauna in lowland rainforest and agricultural systems of Sumatra: Changes in community composition and trophic structure with focus on Collembola
(2022-02-17)Rainforest conversion to agricultural plantations such as rubber and oil palm in Indonesia is increasing in the last decades. In this thesis, I investigated effects of rainforest conversion to rubber and oil palm plantations ... -
Plant - Invertebrate Interactions in Agriculturally Managed Grasslands Under Functional Group Manipulation
(2013-12-12)Within the last few centuries the rapid growth of the human population, along with increasing economic development, has caused increasing demands for agricultural products such as food and fuel. This has led to an extension ... -
Services and disservices driven by ant communities in tropical agroforests
(2013-05-30)Agricultural productivity and human well-being are built upon ecosystem services and disservices. Ants in tropical agroecosystems drive a complex network of direct and indirect interactions between crops and their mutualists ... -
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 ...
