Community dynamics and trophic niches of soil fauna in Central European forests
(2024-09-06)Global change is altering the state of forest ecosystems, threatening their integrity. A number of studies have reported declines in aboveground arthropod diversity over the last decade and indicated management practices ... -
Analyzing host shift patterns of Wolbachia (Alphaproteobacteria) among arthropods using comparative genomics
(2024-05-28)In this thesis, I investigated the host shift event and patterns of the endosymbiotic bacterium Wolbachia. I examined the molecular diversity and distribution of Wolbachia among arthropod communities of different terrestrial ... -
Changes in Microbial Resources and Trophic Niches of Microarthropods in Forest Ecosystems with Elevation
(2024-03-27)Mountain forests play a major role for biodiversity conservation, carbon storage and hydrological cycling. Therefore, understanding different components of mountain forest ecosystems is essential to predict potential ... -
Diversity and Trophic Ecology of Arboreal Spider (Araneae) Assemblages along a Transformation Gradient from Lowland Rainforest to Oil Palm Plantations in Jambi Province, Sumatra, Indonesia
(2023-03-02)In chapter 2, I investigated the canopy spider abundance, biomass, richness and community composition across a land-use gradient from tropical lowland rainforest via jungle rubber to monocultures of rubber and oil palm. ... -
The structure of coastal invertebrate communities and their temporal and spatial dynamics
(2022-11-22)The Wadden Sea is one of the largest tidal flats in the world, stretching across the coasts of the Netherlands, Germany and western Denmark. Along sheltered coastlines lie salt marshes which are essential habitats for a ... -
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 ... -
Cognition in narrow-striped mongooses, Mungotictis decemlineata, a Malagasy carnivore species
(2021-02-11)Carnivores include a wide variety of species that differ in social organization and brain-size, but these two characteristics do not seem to be linked to each other. Additionally, previous studies found no evidence of ... -
Reproductive strategies of alpine apomictic plants under different ecological conditions
(2019-06-06)The origin of apomixis in natural populations is still not well understood. Apomictic plants tend to expand their distribution range more to higher latitudes and altitudes compared to their sexual progenitors, a phenomenon ... -
Flooding in a grassland diversity experiment: response of microorganisms, microarthropods and predator prey interactions
(2018-06-26)Flooding frequency is predicted to increase during the next decades. This will need a better understanding of flood impacts on terrestrial ecosystems and the development of strategies to mitigate potential damage. Plant ... -
Roots of Primate Cognition. The Primate Cognition Test Battery applied to three species of lemurs (Varecia variegata, Lemur catta and Microcebus murinus).
(2018-05-16)Compared to other mammals, primates have evolved relatively large brains and outstanding cognitive skills. Given that brain tissue is energetically very costly, one major evolutionary question concerns possible selection ... -
Conservation physiology of two closely related, sympatric lemur species, the fat-tailed dwarf lemur (Cheirogaleus medius), and the gray mouse lemur (Microcebus murinus)
(2017-10-30)The detrimental effects of human-induced habitat loss and degradation on wildlife are pervasive and represent a primary concern for conservation biologists. Understanding how organisms accurately recognise and respond to ... -
Influence of warming on microbial ecosystems
(2017-02-13)Climate change is progressing fast causing losses in biodiversity to the extent that scientists believe the world to be on the brink of the sixth wave of mass extinction. While some global change drivers like pollution, ... -
Altitude, litter quality and availability of root derived resources as determinants of decomposition processes and soil microarthropod community composition in tropical montane rainforests in Southern Ecuador
(2016-11-03)Decomposition processes in the high tropical Andes are complex and influenced by a variety of biotic and abiotic factors. Tropical montane rainforests of the high Andes harbour large stocks of dead organic material and ... -
Trophic structure of soil animal food webs of deciduous forests as analyzed by stable isotope labeling
(2016-10-26)Forest soil invertebrates are extremely diverse and form complex food webs. Trophic interactions are concealed from direct observation by the heterogeneous soil system and small size of soil invertebrates and their basal ...
