Holocene vegetation and environmental changes with a focus on peat ecosystems in southwestern and northeastern Amazonia
(2024-03-27)Amazon rainforests are well-known for playing a significant role in the climate, hydrological cycle, and biodiversity on earth. Recent investigations found that Amazonia may contain the largest peat carbon (C) stock in the ... -
The phosphorus and nitrogen nutrition of European beech under a future warmer and drier climate: climate chamber experiments and transect studies
(2023-03-13)Productivity of temperate forests may increasingly be limited by phosphorus (P) shortage, as indicated by decreasing P concentrations and increasing nitrogen (N):P ratios in leaves and fine roots and reports on recent ... -
Plant community composition and biodiversity of irrigated rice ecosystems in Vietnam and the Philippines
(2021-11-26)Irrigated rice landscapes in tropical and subtropical Asia are complex agroecosystems that have evolved mostly from natural wetlands. Millennia of interaction between human communities and their surrounding ecosystems have ... -
Ploidy-dependent effect of prolonged photoperiod on mode of reproduction and photosynthesis in the Ranunculus auricomus complex (Ranunculaceae)
(2021-07-23)Polyploidy, whole-genome duplication, enhances stress-tolerance to drastic environmental compared to their diploid progenitor by enabling more extensive adaptation as advantages of gene and genome duplication. Polyploidy ... -
Vegetation and fire history in Araucaria forest and Grasslands, Southern Brazil
(2021-06-18)Southern Brazil offers a great opportunity to analyse woodland and grassland mosaics, their pollen-vegetation relationships and its long-term vegetation and fire history. This research was carried out in two stages; first ... -
Evolution of Melicope J.R.Forst & G.Forst (Rutaceae), the largest adaptive radiation of woody plants on the Hawaiian Islands.
(2020-11-27)Adaptive radiation describes the divergence of an ancestral taxon into multiple, phenotypically diverse species, adapted to a range of ecological niches by means of natural selection. The process is recognized as a fundamental ... -
Studies on vegetation-, fire-, climate- and human history in the mid- to late Holocene - a contribution to protection and management of the forest-steppe-biome in the Mongolian Altai
(2020-09-10)In this thesis, several sedimentological archives from Altai Tavan Bogd National Park are studied to reconstruct the vegetation-, fire-, climate- and human history of the forest-steppe biome in the Mongolian Altai. The ... -
The role of tree height and wood density for the water use, productivity and hydraulic architecture of tropical trees
(2020-06-24)Tropical forests are the world’s most productive terrestrial ecosystems and of central importance for global carbon and water cycles. Global climate projections predict increases in average temperature and an elevated ... -
Diversity, composition, and biogeography of trees in tropical mountain forests of Sulawesi, Indonesia
(2019-10-28)Human activities are increasingly threatening the integrity of Earth’s ecosystems. For successful conservation measures, one necessary prerequisite is an adequate level of understanding about the ecosystems and their ... -
Palaeoecological Evidence of Ecosystem Dynamics in Sumatra, Indonesia. Case Studies of Tropical Submountains and Mangroves
(2019-07-03)The mountain and mangrove ecosystems are an important component of Sumatra’s landscape. These highly diverse ecosystems provide numerous ecological services as well as socio-economic function, but they are also sensitive ... -
The effect of the mycorrhizal type on root-rhizosphere interactions in AM and ECM tree species: field studies and mesocosm experiments
(2019-02-20)Based on the two main types of mycorrhizal associations in temperate forests, which are arbuscular (AM) and ectomycorrhiza (ECM), the idea of a mycorrhizal-associated nutrient economy framework developed (Phillips et al., ... -
Late Quaternary vegetation, climate and ocean dynamics inferred from marine sediment cores off southeastern South America
(2018-09-04)Southeastern South America harbour highly diverse and species-rich ecosystems, such as the Atlantic rainforest, Araucaria forest and grasslands, which occur in a transitional zone from tropical to subtropical. This climatic ... -
Dendroecological investigations on subfossil mire pine woodland in northwest Germany
(2018-02-23)The present work is a dendrochronological investigation of peat-preserved pines (Pinus sylvestris) from northwest German mires (Fed. State of Lower Saxony). The project (DFG funded project LE 1805/2-2) continued the work ... -
Vegetation and functional diversity of sand dune habitats between and within different bioclimatic regions
(2017-08-08)Use of plant functional types has a long tradition in ecology from the time that von Humboldt offered the first physiognomic classification of plants based on growth form. In recent years, the application of functional ... -
Shade trees in cacao agroforestry systems: influence on roots and net primary production
(2016-09-19)Huge areas of natural forests are rapidly cleared worldwide to make way for agricultural cultivation systems. This has a substantial impact on the functioning of ecosystems, as well as on carbon cycling and hence effects ... -
Long-term dynamics of tropical rainforests, climate, fire, human impact and land-use change in Indonesia
(2016-05-09)The research conducted and compiled in this thesis contributes to the knowledge of the long-term vegetation, climate and fire dynamics as well as human impact on montane and peat-swamp rainforests of Indonesia. We applied ... -
Comparisons of modern pollen deposition with vegetation abundance and landscape pattern in NE-Germany
(2015-06-17)Since the introduction of pollen analysis for vegetation reconstruction, scientists have been concerned about the influence of different pollen productivities of individual taxa. A second long standing question focuses on ... -
Vascular plant species richness at the landscape scale: Patterns and processes
(2015-02-27)The heterogeneous geographic distribution of species richness has fascinated and challenged biologists over centuries. As a result, a large number of possible hypotheses that aim at explaining these patterns have been ... -
Landscape change and impoverishment in North German grasslands since the 1950s
(2014-09-05)Landscape and agricultural management has changed in Central Europe dramatically since the large-scale intensification processes (e.g. meliorations, synthetic fertilizer and herbicide use) started in the 1950/60s. Today, ... -
