Abundance, niche breadth and stress in the centre and at the border of the distribution range.
(2008-11-10)Macroecology investigates abundance and distribution patterns over large geographical scales. Some patterns, like the positive relationship between range size and abundance or niche ... -
Die Bedeutung der Epiphyten im ökosystemaren Wasser- und Nährstoffumsatz verschiedener Altersstadien eines Bergregenwaldes in Costa Rica
(2002-12-09)In a comparative study, conducted in the Costa Rican Cordillera Talamanca, a chronosequence of three different successional stages of an upper montane rain forest was investigated. This ... -
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 ... -
Blattwasserzustand und Wasserumsatz von vier Buchenwäldern entlang eines Niederschlagsgradienten in Mitteldeutschland
(2003-12-15)1. The aim of the study was to analyze the plasticity of common beech (Fagus sylvatica L.) in water use and the regulation of water balance in adaptation to forest sites with widely differing precipitation regimes. The ... -
Butterfly communities in the natural landscape of West Khentej, northern Mongolia: diversity and conservation value
(2006-01-16)This thesis provides an insight into the natural history of butterfly species which are found in the West Khentej mountains of northern Mongolia. The study area is located in the transition ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
Drought Adaptation of the Fine Root System and Hydraulic Architecture of Larix sibirica at its Southern Distribution Limit General introduction
(2015-01-12)Taiga-steppe ecotone is a natural grassland habitat with isolated forest islands and low precipitation (c. 100-250 mm yr-1), and is an important part of the boreal biome. The southernmost distribution limit of Siberian ... -
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 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 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 ... -
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 ... -
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 ... -
Experimentelle Untersuchung der Wasseraufnahme und der hydraulischen Eigenschaften des Wurzelsystems von sechs heimischen Baumarten
(2004-08-25)The aim of this study was to investigate the water uptake of the tree species sycamore (Acer pseudoplatanus), ash (Fraxinus excelsior), small-leaved lime (Tilia cordata), hornbeam (Carpinus ... -
Fine root dynamics and resource uptake in a South Ecuadorian mountain rainforest as dependent on elevation
(2008-09-11)Tropical mountain rainforests extend over large elevational gradients with diverse climatic conditions. They are characterised by a decrease of above ground biomass, and a pronounced increase ... -
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 ...
