Ecological analysis of large floristic and plant-sociological datasets – opportunities and limitations
(2018-05-07)This thesis comprises opportunities and limitations for the analysis of floristic and plant-sociological datasets and presents four related exemplary case studies. Woody plant species, their isolated metapopulations and ... -
Ecological and socio-economic effects of industrial oil palm plantations in Southwest Cameroon
(2020-05-14)Rural agroforestry landscapes in West and Central Africa face a number of threats. Since decades, the ever escalating bushmeat crisis is pushing populations of threatened wildlife closer to extinction in many parts of West ... -
Ecological determinants of social systems: Comparative and experimental feeding ecology of two mouse lemur species (<i>Microcebus berthae, M. murinus</i>)
(2009-01-13)The socio-ecological model (SEM) integrates ecological factors with characteristics of social systems and allows predictions about the relationships between resource distribution, type ... -
Ecological groups of Collembola in agroecosystems as affected by farm-based management practices
(2022-12-15)Present day agriculture is identified as a main threat to biodiversity. At the same time, the productivity of agricultural systems is relying on ecosystem services provided by biota. In order to conserve critical ecosystem ... -
Ecological impacts of biodiversity enrichment in oil palm plantations
(2016-01-12)Land-use change is one of the major drivers of biodiversity loss. To satisfy the demand for palm oil in food and biofuel, complex, species-rich rainforests are converted into large, simply-structured mono-culture oil palm ... -
EEG-Kohärenzanalysen zu kognitiven Prozessen im Arbeitsgedächtnis
(2001-07-23)The thesis deals with short term cognitive processes that occur during the retrieval of verbal resp. nonverbal information from working memory. Particularly, it affects the question whether ... -
Effect of acute phase cytokines on iron uptake in hepatocytes and differential localization of Lipocalin-2 and Transferrin receptors in rat hepatic and extra hepatic organs
(2014-08-28)Acute phase response (APR) is the systemic reaction to tissue injury and inflammation. It is clinically characterized by systemic symptoms such as fever, weakness, and anemia, somnolence loss of appetite and cytokines ... -
Effect of nitric oxide and inflammatory mediators on axonal transport
(2005-11-04)Increased production of inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and reactive oxygen species by glia in the central nervous system (CNS) is a hallmark of a variety ... -
Effect of radiation on hepatic fat metabolism in rat and mouse: A role of radiation-induced TNF-α in the regulation of FAT/CD36
(2015-08-13)Radiotherapy is an important method to treat tumors. The positive effects of irradiation on tumoral tissue are thought to be due to the damage of the DNA of tumor cells and the damage of tumor vessels. Radiation as single ... -
Effect of Radiation on Leukocytes Migration and Gene expression of Rat Liver Chemokines: In-vivo and In-vitro Studies
(2010-02-01)Liver damage is a serious clinical complication of gamma-irradiation. CXC- and CC-chemokines, known to attract inflammatory cells, play a role in transmigration process during inflammation. Chemokines are generated locally ... -
Effects of agri-environmental measures in intensively managed farmland on the soil seed bank, butterflies and carabid beetles in Germany - Influence of local conditions and surrounding landscape on biodiversity
(2023-09-26)Monitoring of the soil seed bank, butterflies, and carabid beetles, representing different trophic groups, provides an insight into the broader effects of agri-environmental measures in intensively used arable landscapes. ... -
Effects of air humidity on development, physiology and distribution of temperate woodland herbs and tree saplings
(2008-04-14)How growth and morphology of wild plants are controlled by the relative air humidity is not sufficiently understood. The present study investigated long-term effects of contrasting air humidity levels on growth, physiology ... -
Effects of anle138b treatment on amyloid-β neurotoxicity
(2020-10-02)Alzheimer’s disease (AD), the leading etiology of dementia and the fifth cause of death worldwide, has been declared a public health priority by the World Health Organization in 2017. AD is incurable and no treatment can ... -
Effects of anthropogenic pressure on large mammal species in the Hyrcanian forest, Iran
(2018-01-24)Anthropogenic activities, such as overexploitation (poaching, logging) and farming (livestock grazing), are the most serious threats to biodiversity and ecosystem services. The effects of these drivers may be synergistic ... -
Effects of climate change and land use on the structure and function of earthworm communities
(2024-05-07)Human activity-induced global change is increasingly threatening biodiversity and composition of species assemblages worldwide, which reduces ecosystem resilience and provokes concerns about ecosystem functions. Over the ... -
Effects of cold stress on reproductive biology and epigenetic profiles of the alpine plant Ranunculus kuepferi (Ranunculaceae)
(2022-01-17)Alpine habitats are shaped by harsh abiotic conditions and cold climates. Plant life in such habitats is challenging, as environmental influence can alter the conditions for development and reproduction. More specifically, ... -
Effects of experimental drought on hydraulic properties and leaf traits of upper canopy and understory tree species in a perhumid tropical forest in Central Sulawesi, Indonesia
(2010-12-07)The remaining tropical moist forests may be threatened in future by more frequent and more severe droughts that come along with the predicted climate change in South-East Asia and South ... -
Effects of forest fragmentation on brown spider monkeys (Ateles hybridus) and red howler monkeys (Alouatta seniculus)
(2013-09-13)The increasing intensity of anthropogenic land use and conversion has immense impacts on ecosystems worldwide and often results in habitat fragmentation. Fragmentation and other anthropogenic disturbances (e.g. hunting and ... -
Effects of human disturbance on epiphyte assemblages in the Andes of Ecuador
(2009-03-04)The present dissertation aims at contributing to our understanding of the processes that determine epiphyte diversity in anthropogenic landscapes. At a dry forest site, epiphytic ... -
