An investigation of temporal variability of CO2 fluxes in a boreal coniferous forest and a bog in central Siberia : from local to regional scale
(2019-07-19)Boreal forests and peatlands are the major types of vegetation in northern Eurasia. These ecosystems store large amount of carbon in their vegetation and soil, thus are essential ecosystems to understand the global carbon ... -
Atmospheric Variability in Sulawesi, Indonesia
(2006-12-20)This dissertation discusses the modelling of atmosphere parameters on Sulawesi Island, Indonesia using different atmospheric models. The main character of climate in Central Sulawesi is a ... -
Auswirkungen von Ökosystemmanipulationen auf Vorratsänderung und Freisetzung von C- und N- Verbindungen
(2006-10-12)The organic material (OM) in soil plays an essential role as well in the structure as in the function of terrestrial ecosystems. The amount and distribution of OM in soil is characteristic ... -
Carbon Fluxes and Pools in a Montane Rainforest in Sulawesi, Indonesia
(2021-03-18)Forests play an important part in the global carbon cycle. While carbon balances of many forest types have been studied intensively, such information is very sparse for tropical montane rainforests. This thesis aims to ... -
Changes in eco-hydrological functioning after tropical rainforest transformation to rubber and oil palm plantations
(2015-10-09)This work presents findings from eco-hydrological research carried out in Jambi, Sumatra, Indonesia in the framework of the CRC990 (Sub-Project A02). Our results point to substantial changes in central ecosystem water ... -
Competition mechanisms of native and exotic tree species
(2014-01-09)The amount of exotic plant species introduced to new regions by humans has considerably increased in the last two centuries. Worldwide, the invasion of exotic species represents an important threat to native biodiversity ... -
Diversity and abundance of medicinal plants among different forest-use types of the Pakistani Himalaya
(2012-02-06)Medicinal plants collected in the Himalayan forests are receiving increasing attention at the international level for a number of reasons and they play an important role in securing rural ... -
Diversity and composition of tree communities in the mosaic landscape of north-eastern Madagascar
(2022-01-14)In Madagascar, a large percentage of the rural human population faces multifaceted poverty and depends on agriculture and natural resources as main livelihood sources. Consequently, the country’s biodiverse natural ecosystems ... -
Dynamik von Phosphor im Boden und von Nährstoffen im Kronenraum von Buchenwäldern unterschiedlicher Baumartendiversität
(2010-03-17)Soil nutrient pools, concentrations and turnover as well as soil nutrient inputs due to deposition and canopy exchange have been studied intensively in all kinds of forest ecosystems ... -
Effects of increased nitrogen input on the net primary production of a tropical lower montane rain foest, Panama
(2009-09-11)Increasing anthropogenic nitrogen (N) deposition from agricultural and industrial use, legume cultivation, combustion of fossil fuels, and biomass burning has until recently been a problem ... -
Etablierung von Nothofagus obliqua, Nothofagus glauca und Quillaja saponaria in der mediterranen Zone Chiles
(2019-10-30)Within the framework of the overall research project "Tree diversity in Mediterranean forests in Chile: are close-to-nature forestry and profitability mutually exclusive?" a field experiment with three Chilean tree species ... -
Functional traits of vascular plants on islands across spatial scales
(2024-02-22)Islands have unique and disharmonic floras, resulting from the filtering effects of dispersal and climate and, in some cases, their high evolutionary diversification rates. Due to their small size and distinct boundaries, ... -
Further development and adaptation of large area forest inventories and remote sensing applications to comprehensive data providers for international processes
(2011-10-31)With this study we present a forest inventory approach on national level for Burkina Faso where a relatively small sample size is combined with relatively large sample plots. To our knowledge, ... -
Global macroecology of ant-plant mutualisms: The role of biotic interactions in shaping species diversity and composition patterns
(2023-12-11)Understanding the mechanisms underlying patterns of species distribution and diversity is a central goal in ecology and biogeography. Biotic interactions have been acknowledged as important factors affecting species diversity ... -
Growth, hydraulics and functional traits of Melia dubia across a steep climatic gradient in southern India
(2022-11-16)The global demand for wood has been continuously increasing and the world is also witnessing large-scale deforestation. This is largely contributing to global warming, land degradation and biodiversity loss. Quite a large ... -
