Effects of different energy cropping systems on plant diversity in Central German agricultural landscapes
(2015-08-17)The rich biodiversity of the Central European farmland is to a large extent directly dependent on human management decisions. Diverse and dynamic biocoenoses have developed in mutual interactions with farming practices, ... -
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 ... -
Effects of earthworms and tree species (Fagus sylvatica L., Fraxinus excelsior L.) on greenhouse trace gas fluxes in mixed deciduous broad-leaved forests
(2015-02-25)Despite the large number of studies and the associated knowledge gain uncertainties on the determinants of greenhouse gas fluxes from terrestrial ecosystems still exist. It is important to bridge these gaps as land use and ... -
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 ... -
Environmental heterogeneity–species richness relationships from a global perspective
(2014-12-11)Spatial environmental heterogeneity (EH) is regarded as one of the most important drivers of species richness gradients worldwide. Its association with increased available niche space, provision of refuges, and opportunities ... -
The Macroecology of Island Floras
(2014-12-09)Marine islands harbour a great part of our planet’s biological diversity and a high proportion of endemic species. However, island biota are particularly susceptible to anthropogenic threats like climate change, habitat ... -
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 ... -
Mycorrhizal fungi in deciduous forests of differing tree species diversity and their role for nutrient transfer
(2014-07-25)Mycorrhizal fungi are forming EcM on beech (Fagus sylvatica L.) and AM on ash (Fraxinus excelsior L.) and are an important component of several ecosystem processes in forests. One main functional role is nutrient acquisition, ... -
Intra- and interspecific variation of functional traits, growth performance and belowground competition in <i>Populus</i> species
(2014-06-06)Short-rotation forestry (SRF) systems provide sustaining resource supply that is needed to meet the rapidly increasing demand in wood products and renewable energy. Poplar species (Populus spp.) are frequently used ... -
Pollination ecology and spatial genetic population structure of wild and cultivated species of cacao (Theobroma) in Bolivia
(2014-03-19)Tropical forest in southwestern Amazonia is threatened by increasing human populations, economic exploitation, deforestation and burning activities for cattle raising and agriculture. Tropical rainforests are characterized ... -
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 ... -
Functional diversity of mycorrhizal fungi with regard to nutrient transfer
(2013-11-11)Mycorrhizal associations of tree species are important drivers of plant belowground interactions. The main objective of this study was to investigate the contribution of mycorrhizal fungi on plant competition for nutrients. ... -
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 ... -
Studies on late Quaternary environmental dynamics (vegetation, biodiversity, climate, soils, fire and human impact) on Mt Kilimanjaro
(2013-09-10)Sediments of buried soils from different key areas at Mt Kilimanjaro are studied to reconstruct former and to predict future landscape dynamics on Mt Kilimanjaro. This contributes to a better understanding of local and ... -
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 ... -
Respone of tree-ring width and regeneration in conifer forests of Mongolia to climate warming and land use
(2013-07-19)This thesis presents research results from isolated larch forest islands at high altitude (ca. 2300 m a.s.l.) in the Altai Mountain, which are used for mobile livestock husbandry. In addition, investigations from the central ... -
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 ... -
Phylogeography and impact of hybridization on the evolution of African green monkeys (Chlorocebus Gray, 1870)
(2013-06-04)The evolution of the current global biodiversity has been profoundly influenced by climatic and environmental changes over the past million years. While there is an obvious impact of Quaternary climate changes and glacial ... -
