From Plot to Region: Assessing the Role of Land Use in Tropical Montane Forest Structure and Dynamics
Forest disturbance and land use are strong drivers of forest structure, composition, and dynamics and yet, their role in shaping tropical montane landscapes is poorly understood. The overarching goal of my dissertation is to broaden our understanding on the role of land use in shaping forest …

Ectomycorrhizal associations in tropical montane forest: insights into their influence on nutrient cycling and functional responses to soil fertility
In Panamanian montane forest, the ectomycorrhizal tree Oreomunnea mexicana forms monodominant stands where it accounts for up to 70% of individuals. Monodominance is unexpected in tropical forest because the accumulation of host-specific pathogens is thought to limit the local abundance of …

Soil respiration, microbial respiration and mineralisation in soils of montane rainforests of Southern Ecuador: influence of altitude
Impacts of land use and climate change in tropical forests on the global carbon budget are of principal interest in the recent research, as these forests amount to about 48 % of the world’s forested area. Interest has been focused on lowland tropical forests mainly, but tropical montane forests …

Biogeochemical Consequences of Hydrologic Conditions in a Tropical Montane Rain Forest in Ecuador
Tropical montane forests regulate the hydrological cycles of high-elevation areas being an important service for the local population. The objectives of my work were (1) to determine the major hydrological flow paths, (2) to quantify concentrations of dissolved organic C and organic and inorganic …

Pollination Biology of Gentianales in a Southern Ecuadorian Montane Forest
… and Rubiaceae) was investigated in a tropical montane forest in southern Ecuador. This study is part of an interdisciplinary project on the diversity and functioning of a montane ecosystem, and provides important results with respect to pollination biology. Such data are rarely …

Analysis of the "nurse-tree effect" of exotic shelter trees on the growth of the indigenous Podocarpus falcatus in an Ethiopian montane forest
Ethiopian forests disappear with a rate of 1.1% per year due to the high demand of firewood and timber. To protect the remaining parts of the forests, exotic tree plantations were established 60 years ago. But there are considerable concerns regarding exotic plantations: they have the reputation to …

Relationships between soil chemical properties and forest structure, productivity and floristic diversity along an altitudinal transect of moist tropical forest in Amazonia, Ecuador.
… von ungestörten höheren Tiefland zu montanen Primärwäldern in Nordost Ecuadors, im Gebiet des Sumaco Biosphären Reservates (SBR), untersuchten wir die die Hypothesen, dass (1) die Verfügbarkeit von Phosphor niedrig ist in den tiefer gelegenen Wäldern und mit zunehmender Höhe ansteigt, …
