Landscape Scale Spectral-Temporal Modelling Of Bamboo-Dominated Forest Succession Within The Atlantic Forest Of Southern Brazil, Clara Greig
Theses and Dissertations (Comprehensive)
Tropical and subtropical ecosystems have become vulnerable to biological invasion (i.e., bamboo) due to human induced forest fragmentation. Bamboo ecological processes have been found to impede forest development, resulting in a state of arrested succession, which has been found to significantly reduce biodiversity, thus contributing to biotic homogenization. In this study we use a semi-empirical approach to develop a community-level spatially explicit ecological process model (hybrid model) using a time-series of Landsat imagery to describe single-landscape scale ecological processes of a pervasive bamboo species (Merostachys skvortzovii) found throughout the Araucaria forest, a critically threatened subtype of Atlantic forest …

The Effects Of Fire On Snow Accumulation, Snowmelt And Ground Thaw On A Peat Plateau In Subarctic Canada, Elyse Mathieu
Theses and Dissertations (Comprehensive)
During the past century, the highest rates of warming have occurred at latitudes above 60oN, where air temperatures have risen at twice the rate of other regions. In northwestern Canada, this warming has coincided with an increase in the frequency, size and severity of wildfires. The influence of such fires on the trajectory of on-going permafrost thaw is not well understood. As a consequence, the combined impacts of climate warming induced permafrost thaw and possible feedbacks arising from wildfires cannot be properly assessed. This study examines the impact of a 2.7 ha low-severity wildfire (July 2014) on water …
