Palynological studies and Holocene ecosystem dynamics in north western Khyber Pakhtunkhwa Province of Pakistan in the Hindu Kush Himalayan region
(2016-04-28)Khyber Pakhtunkhwa (31°49´N, 70°55´E to 35°50´N, 71°47´E) is located in north western Pakistan in south Asia. The Hindu Kush mountains of Afghanistan lies to its west, Indian Himalayas to the northeast and Karakorum Mountains ... -
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 ... -
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 ... -
Plant diversity and landscape-scale effects on multitrophic interactions involving invertebrates
(2018-11-12)Biodiversity in terrestrial ecosystems is declining due to increasing anthropogenic pressure. Urban and agricultural expansion lead to shrinking natural or seminatural habitats. In addition, management intensification of ... -
Plant species and global change agents as driving factors of rhizosphere processes and soil nematode communities
(2013-03-19)The soil system harbors important ecosystem functions. Understanding the factors influencing the functioning of soil systems is crucial to react adequately on changes induced by alteration in plant species compositions and ... -
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 ... -
Prey preferences of the Persian leopard and trophic competition with human hunters in Iran
(2016-09-14)Poaching is a global environmental threat, which drives populations of many species toward extinction. Current levels of poaching are unsustainable, causing substantial impacts on ecosystems and wildlife. By poaching, ... -
Prospects for climate change mitigation of Scots pine and European beech forests
(2022-06-03)The historic large-scale forest conversion in the northern German lowlands resulted in a man-made dominance of Scots pine, in a landscape that would naturally be dominated by forests of European beech. Since drawbacks of ... -
Resilience of Earthworm and Soil Microbial Communities to Agricultural Intensification and Climatic Extremes - A Case Study in the North German Lowlands
(2023-05-16)High demands for agricultural goods such as food, fiber and fodder and at the same time a decreasing farmland area result in an ongoing intensification of agricultural production. This is accompanied by high environmental ... -
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 ... -
Response of European beech to decreasing summer precipitation under global climate change
(2016-07-15)Global warming-related summer precipitation reduction represents a major threat on tree vitality and persistence and hence on forest productivity over large parts of the temperate zone. European beech (Fagus sylvatica L.) ... -
Seasonal habitat use and breeding performance of the Eurasian Skylark (Alauda arvensis) in Central European farmland
(2022-06-21)The Common Agricultural Policy (CAP) of the European Union has often been identified as a driver of recent agricultural intensification and thus of biodiversity loss. All major taxa, including vascular plants, arthropods, ... -
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 ... -
Spatial variation of photosynthetic capacity of early-, mid-, or late-successional broad-leaved tree species in a temperate mixed forest
(2013-03-22)Forests are important not only as a habitat for animal and plant species, but also for economy, protection of soil, local recreation areas and they provide air-purification. Forests which were earlier almost solely ... -
Species-specific fine root biomass, morphology and dynamics of six co-occurring deciduous tree species in the Hainich National Park and a conifer tree species at the alpine treeline
(2016-09-02)This thesis is subdivided into two main research areas. The first two studies were conducted in a mature mixed temperate broad leaved forest with regard to species identity effects on fine root traits, while the third study ... -
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 ... -
Structure, Productivity and Carbon Storage of Primeval European Beech Forests
(2018-06-06)A major part of the potential natural vegetation of central Europe consists of European beech forests (Fagus sylvatica L.). Beech is one of the most important broadleaf tree species for forestry within its distribution ... -
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 ...
