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. ... -
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 ... -
Comparing northern German Scots pine plantations with natural beech forests: Soil carbon pools and growth dynamics
(2023-03-10)Forestry in the North German Lowlands has been historically characterized by pine in particular. Apart from pine, beech is one of the most important deciduous tree species in this region and would naturally also be the ... -
Variability of wood and leaf functional traits in response to structural and environmental changes in natural and transformed systems in Indonesia
(2020-11-20)Warming climate associated with increasing drought spells are threatening plants from both natural and transformed systems of Indonesia. On one side, Indonesian natural forests are home of an incredible plant diversity but ... -
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 ... -
Compositional and functional shifts in belowground fungal communities in tropical land-use systems
(2020-06-23)Tropical low-land rainforests are one of the most diverse ecosystems in the world and provide valuable ecosystem services such as climate change mitigation. They are immensely threatened by expanding human land-use. ... -
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 ... -
Spatial vegetation ecology: Understanding the ecosystem processes that influence plant diversity patterns at different spatial scales
(2019-09-10)The present thesis is based on a set of 16 peer-reviewed publications originating from ecological research work aimed at understanding how ecosystem processes may influence plant diversity patterns at different spatial ... -
Vascular plant and cryptogam diversity in Fagus sylvatica primeval forests and comparison to production stands in the western Carpathian Mountains, Slovakia
(2019-06-07)Summary Conflicting evidence exists with respect to the putative effect of forest management on plant species diversity. Various published studies have concluded that primeval forests are not that species-rich and that ... -
Belowground plasticity of European beech – Studies on the variability of beech fine root system size, structure, morphology, and anatomy, and on their impact on soil organic matter in the top- and subsoil of six beech forests with different bedrock types in Northern Germany
(2019-02-01)Trees’ rooting systems have a fundamental role in the acquisition of water and nutrients from the soil and they are thought to be inherently plastic with regards to their size, structure, morphology and anatomy in order ... -
Root system structure and functions across coastal saltmarsh flooding gradients
(2018-12-04)Salt marshes are ecosystems with extreme environmental conditions such as regular tidal inundation, mechanical disturbances, salinity, waterlogged and anoxic soils, and potentially toxic compounds in the soil. This adverse ... -
Untersuchung der Lebensraumansprüche des Grauspechts Picus canus und seiner Verbreitungsgrenze in Niedersachsen
(2018-06-11)The grey-headed woodpecker (Picus canus) is a semi-frequent species distributed worldwide from West France over Central Europe and East Russia up to Japan and Sumatra. The populated habitats vary and comprise boundary-abundant ... -
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 ... -
Effects of tree species diversity and soil drought on productivity, water consumption and hydraulic functioning of five temperate broad-leaved tree species
(2016-07-01)Biodiversity is by now widely known to strengthen functioning and services, like primary production and element cycling, for a broad range of ecosystem types. However, it is less clear yet if and how this relationship also ... -
Carbon pools and sequestration in vegetation, litter dynamics and hydraulic anatomic properties in rainforest transformation systems in Indonesia
(2015-11-23)Globally rising demand for cash crops such as oil palm, rubber, and cacao is driving the extensive conversion of natural rainforests in Southeast Asia with increasing speed. The consequences for humans and nature are immense ... -
Climate response of above- and belowground productivity and allocation in European beech
(2015-05-28)European beech (Fagus sylvatica L.) is by far the most abundant tree species of Central Europe’s natural forest vegetation and one of the economically most important trees in Germany. Although this late-successional tree ... -
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 ... -
Students’ Interests in Agriculture: The Impact of School Farms Regarding Fifth and Sixth Graders
(2015-02-24)The present way of intensive agricultural production is closely connected to central issues of sustainable development such as the loss of biodiversity and climate change. The corresponding importance of agriculture stands ... -
