Fall 2016
The increasing anthropogenic pressure on biodiversity in the tropics is resulting in changes to ecosystem structure and increasing species extinction rates (Collen et al. 2013). These issues are heightened in the tropics where 50% of the world’s biodiversity is held in 7% of the world’s...

Monitoring year-to-year variability in dry mixed-grass prairie yield using multi-sensor remote sensing
DownloadFall 2012
The Normalized Difference Vegetation Index (NDVI) and harvested biomass were compared to assess rangeland productivity (above-ground green biomass or “yield”) in southern Albertan dry mixed-grass prairie. Seasonal trends during the 2009 and 2010 growing seasons were investigated using harvested...

This thesis explores the variability of leaf traits resulting from changes in season, ecosystem successional stage, and site characteristics. In chapter two, I present a review of the use of remote sensing analysis for the evaluation of Neotropical dry forests. Here, I stress the conclusion,...
