The influence of temperature, nutrient availability and soil depth on root exudation in european beech forests
(2023-03-10)The availability of mineral nutrients (i.e. N, P) in unfertilized soils is often not adequate to meet plant demand, which in turn creates a necessity to fulfil the supply requirements from nutrient release from soil organic ... -
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 ... -
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 ... -
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 ... -
Effects of moderate Nitrogen and Phosphorus addition on the species composition and dynamics of the three seedlings community in tropical montane forests in southern Ecuador
(2016-10-28)Anthropogenic activities have produced changes in natural ecosystems worldwide. In tropical regions in South America, industrialization of cities and forest clearance via burning are the main activities releasing pollutants ... -
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 ... -
Conservation, biodiversity and governance of semi-natural grasslands in Southern Transylvania (Romania)
(2014-09-03)Semi-natural grasslands are species-rich habitats of major importance for many taxonomic groups and as a provider of ecosystem services, yet are becoming increasingly rare and thus a conservation priority in Europe. The ... -
Effects of tree species composition on fine root biomass and dynamics in the rhizosphere of deciduous tree stands in the Hainich National Park (Thuringia)
(2013-11-20)During the past two decades, much research has focused on understanding the role of biodiversity for ecosystem functioning and the provision of ecosystem goods and services for humanity. While several experiments with ... -
Hydraulic traits and their relevance for water use strategies in five broad-leaved tree species of a temperate mixed forest
(2013-11-14)Without anthropogenic intervention, Central Europe would be covered by about 65% by beech-dominated broad-leaved forests. However, large forest areas have been replaced by coniferous monocultures since the early 19th century ... -
Habitat ecology and long-term development of the macrophyte vegetation of north-west German streams and rivers since the 1950s
(2013-11-08)This PhD thesis deals with the habitat characterization and the long-term development over 60 years of the macrophyte vegetation of north-west German running waters in order to contribute to the knowledge about the ecology ... -
Impoverishment of the arable flora of Central Germany during the past 50 years: a multiple-scale analysis
(2013-05-30)Since the first creation of arable land a crop-adapted flora and fauna has developed as a byproduct of low-intensity agriculture. Intensification and economic optimization of agricultural production during the last few ... -
Variability of physiological traits and growth performance in aspen assemblages differing in genetic relatedness
(2011-03-25)Due to the increasing demand for wood and renewable energy sources, short-rotation forestry with its reliance on highly productive Populus species is in the focus of current ecological ... -
Diversity and tree neighborhood effects on the growth dynamics of European beech and the stand seed bank in temperate broad-leaved forests of variable tree diversity
(2010-06-11)Among the recent studies investigating species diversity s effect on ecosystem functioning, only few examine long-term changes. My study addresses this question based on seed bank analysis ... -
Water turnover in species-rich and species-poor deciduous forests: xylem sap flow and canopy transpiration
(2010-01-05)The importance of plant diversity for ecosystem functioning has been one of the central research topics in ecology during the past 15 years. While much research has focused on the role of ... -
Elevation Effects on Key Processes of Carbon Cycling in South Ecuadorian Mountain Forests
(2008-12-02)This study on forests in South Ecuador aims at filling some of the great gaps of knowledge on the carbon cycling in mountain rainforests at elevations between 1000 and 3000 m. Special ... -
Fine root dynamics in broad-leaved deciduous forest stands differing in tree species diversity
(2008-10-07)Biodiversity effects on ecosystem functioning in forests have attracted increasing attention only recently. The vast majority of studies in forests focussed on above-ground responses to ...
