Development and Application of a Classification System for Undisturbed and Disturbed Tropical Montane Forests Based on Vegetation Structure
… analysis of undisturbed and disturbed montane rain forest ecosystems in Southern Ecuador. The aim of the study presented here was the development and application of a classification system based on structural characters for both, undisturbed and disturbed forests. In an altitude …

Soil Microbial Diversity and Litter Decomposition Increase with Time Since Land Use Disturbance in Tropical Montane Forests of Malaysian Borneo
… are occurring at alarming rates in the tropical forests of Southeast Asia. These disturbances alter soil chemistry, microbial diversity, and disrupt carbon cycling through shifts in litter decomposition. Direct links between microbial diversity and soil properties such as pH are well …

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 …

Tree community assembly and biogeochemical processes along an elevational gradient in western Panama
Tropical montane forests (TMF) are unique ecosystems with remarkable contributions to global diversity and C cycle regulation. Understanding factors responsible of TMF dynamics are critical to predicting their plant community response to global change. Elevational and environmental gradients are …

Soil-plant dynamics of water, nitrogen and sulfur: A study on indigenous and exotic tree species in Munessa Forest, Ethiopia
… are necessary to counteract the destruction of tropical montane forests. Sustainable forestry requires comprehensive knowledge of tree effects on site conditions and nutrient cycling, but substantial information is lacking even for widely-planted species. In my work, I aimed at identifying such …

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 …

The Use of Biomarker and Stable Isotope Analyses in Palaeopedology / Reconstruction of Middle and Late Quaternary Environmental and Climate History, with examples from Mt. Kilimanjaro, NE Siberia and NE Argentina
… (~ -25‰) compared to those developed under tropical montane forests (~ -27‰), suggesting that such vegetation changes are responsible for the observed d13C pattern. In the Tumara Palaeosol Sequence, d13C correlates negatively with total organic carbon (TOC) and TOC/N. As both parameters may …
