Assembly processes in soil animal communities: Integrating phylogeny and trait-based approaches
(2018-03-02)Soils are among the most biodiverse systems on earth. The coexistence in soils of a multitude of animal species has long puzzled soil ecologists. How can so many species co-occur, and what are the processes driving and ... -
Carbon flow in belowground food webs assessed by isotope tracers
(2016-02-04)Soil food webs are complex networks that consist of several trophic levels and taxonomic groups including soil microorganisms, protists, nematodes, annelids and soil arthropods. Interactions between and within trophic ... -
Changes in trophic structure of decomposer communities with land use in Central European temperate forests
(2014-03-05)Soil animals affect major ecosystem processes, such as nutrient cycling and soil formation, and thereby play a central role in aboveground - belowground interactions. Soil animal food webs are complex trophic networks ... -
Community structure, trophic ecology and reproductive mode of oribatid mites (Oribatida, Acari) in forest ecosystems
(2012-12-19)Oribatid mites are predominantly soil-living organisms reaching densities of up to 400,000 individuals per square meter in forest soils, where they contribute to decomposition processes and nutrient cycling. In acidic ... -
Effects of temperature and body mass on soil communities
(2013-01-11)The Earth is undergoing a climate change with predicted increases in temperature by up to 6° C until 2100. How this warming affects soil food webs is of fundamental interest for mankind as it may influence global food ... -
Exploring patterns of phytodiversity, ethnobotany, plant geography and vegetation in the mountains of Miandam, Swat, Northern Pakistan
(2015-07-08)The study area of Miandam (35° 1′- 5′ N, 72°30′-37′ E) is located in the District of Swat in the Province of Khyber Pakhtunkhwa (formerly North West Frontier Province) in the North of Pakistan. The present project is a ... -
Fungal diversity in a transgenic poplar plantation and the role of ectomycorrhizal fungi for tree performance under field and controlled drought stress conditions
(2013-06-05)The worldw ide increasing energy demand comes along with diminishing fossil fuel resources. Thus, research on alternative bioenergy sources is urgently needed. Poplars with optimized properties for bioethanol ... -
Genetic diversity of sexual and parthenogenetic soil living arthropods (Collembola) in Europe: colonization patterns, pre-glacial diversifications and founder effects
(2016-04-01)Large parts of northern and central Europe were covered by ice sheets and permafrost due to climate changes in Europe during the last ice age (2.7 million to 11.7 kya). Plant and animal species had to adapt to lower ... -
Molecular Analysis of Centipede Predation
(2013-09-30)Soil food webs are an essential part of terrestrial ecosystem functioning and characterised by a high degree of cross linkage between the members of a highly diverse soil community. Centipedes are abundant predators in the ... -
Phylogeography in sexual and parthenogenetic European oribatida
(2011-01-20)Oribatid mites (Acari, Oribatida) are a species rich group which may form the oldest group of Chelicerata, as indicated by fossils from Devonian sediment (~380 million years) and molecular ... -
Soil animal food webs in temperate forests: effects of forest management on trophic structure as indicated by molecular gut content, stable isotope and fatty acid analyses
(2015-01-19)The soil system comprises a high diversity of coexisting species interacting in close association. Generally, soil animals are assumed to be trophic generalists feeding on resources of even different trophic levels. The ... -
Spread and performance of European earthworms invading North America as indicated by molecular markers and climate chamber experiments
(2018-10-15)European lumbricid earthworms were introduced into northern North America by European settlers about 400 years ago. They are invasive across the continent and cause notable changes in native forest ecosystems. Human-mediated ... -
Structure of and carbon flux through soil food webs of temperate grassland as affected by land use management
(2014-11-06)In Europe grasslands are among the most important agricultural systems. They are subject to continuous management intensification, which is potentially threatening ecosystem services. Since soil comprises the largest ... -
The nematode-based food-chain of a temperate deciduous forest
(2013-05-13)Soils are complex and heterogeneous habitats for soil animals. Trophic interactions between soil animals are depicted in soil food webs which form an essential component of terrestrial ecosystems. Soil food webs are based ... -
The soil food web of temperate deciduous forests: litter and root resources as driving factors, and soil fauna effects on ecosystem processes
(2016-12-16)Above- and belowground communities have been investigated independently for long, but there is increasing evidence that both are intimately linked and depend on each other. Plants provide energy and nutrients for the ... -
Towards a unified allometric and stoichiometric perspective in ecology
(2015-09-09)Ecosystem functioning is maintained by the interplay of a multitude of species. However, in a time of global change there are high rates of species extinctions which can drastically reduce the functionality of natural ... -
Tree species as determinants of the structure of oribatid mite communities (Oribatida) and the incorporation of plant carbon and nitrogen in the soil animal food web
(2013-08-23)In this dissertation I investigated the role of tree species for the structure and functioning of soil animal food webs in temperate forests. In the field, the role of tree species diversity as compared to tree species ...
