Soil-Landscape Modelling in an Andean Mountain Forest Region in Southern Ecuador
… as a key soil attribute. Soils in the Andean mountain rainforest area of southern Ecuador are influenced by hillslope processes and landslides in particular. The lack of knowledge on the distribution of soils and especially physical soil properties to understand slope failure, resulted in the …

Resource partitioning of soil organic phosphorus: investigations from a tropical mountain forest
One of the major limitations of resource-niche theory to explain plant species diversity and distribution is the paucity of recognized resources. Recent investigations in grassland and tundra ecosystems indicate that plant species can specialize to exploit different forms of soil nitrogen. I …

The response of a Rocky Mountain forest system to a shifting disturbance regime
Climate change is likely to drive widespread forest declines and transitions as temperatures shift beyond historic ranges of variability. Warming temperatures and shifting precipitation patterns may lead to increasing disturbances from wildfire, insect outbreaks, drought, and extreme weather …

Long-term Effects of Prescribed Fire and Fire Surrogate Treatments on Southern Appalachian Mountain Forest Soil Chemistry
As a response to rising wildfire hazard and forest structure and composition concerns, the National Fire and Fire Surrogate Study was established in 2000 to determine how fuel reduction and ecosystem restoration techniques might affect ecosystem properties and processes across the United States. …

Analysis and Conservation of Native Forests at Kessler Mountain Fayetteville, Arkansas
<p>Kessler Mountain in Fayetteville Arkansas has long been recognized for its beauty and natural resources. Parts of Kessler Mountain have been homesteaded and developed in the past, but most of the mountain has remained relatively undisturbed. The planned development of over 4,000 housing units to …

Empirische Untersuchung von Durchforstungsbeständen im Bergwald und deren ökonomische Bewertung zur Prioritätsmodellierung, als Bestandteil forstlicher Managementstrategien
Thinning interventions in the mountain forest have to be, from silvicultural points of view, best possibly analyzed to constantly and critically question common processes in professional practice. The problem with significant topicality was summed up in a research question. Can thinning stocks …

Behavioral and Hormonal Flexibility Across Light Environments in Guppies (Poecilia reticulata)
… streams, and the backwaters of small rivers in mountain forest areas of Trinidad (Houde 1997; Magurran 2005). In this study I attempted to answer the following questions using three low predation populations of guppies : 1) Do guppies display a behavioral syndrome for aggression and/or courtship …

Self-incompatibility in Cosmos atrosanauineus: a rare Mexican endemic species of Asteraceae
… century, localise the species to the pine-oak mountain forest ecological region in two areas of central Mexico. Its disappearance from the natural environment is attributed to habitat destruction by the copper mining industry and subsequent urbanisation, so that C. atrosanguineus is now known …

Drivers of forest dynamics: Joint effects of climate and competition
… thesis addresses different aspects of forest dynamics and possible changes due to climate change. Various modelling approaches are used to explore joint effects of climate and competition on forest dynamics with a focus on temperate forests. Motivated by scientific interest, this thesis …

Towards adaptive management of high-altitude grasslands: Ingula as a case study
… of other agricultural projects such man - made forests. Other new developments that need to be mitigated against are development of renewable energy projects such as pumped water schemes to generate electricity or wind farms. Additional habitat is lost when these projects are connected to the …

Elevation Effects on Key Processes of Carbon Cycling in South Ecuadorian Mountain Forests
Diese Studie über Wälder Süd-Ecuadors hat das Ziel große Wissenslücken zu füllen, den Kohlenstoffkreislauf montaner Regenwälder in einer Meereshöhe von 1000 bis 3000 m betreffend. Besondere Aufmerksamkeit wurde dabei auf den bisher unbekannten Kohlenstoffumsatz durch Feinwurzeln, Stammholzzuwachs …
