Effects of interactions between predators, variable predation regimes, and species body size on rocky intertidal communities : comparative and experimental approaches

Creator:

Navarrete, Sergio A.

Abstract:

The body size (W) of animal species is one of the best predictors of population density (D) when large assemblages are considered. It has been shown that theoretically the D-W relationship can be the consequence of two other distributions: the log-normal distribution of body sizes of the species and of...

Economic modeling of tropical deforestation in Antioquia (Colombia), 1980-2000 : an analysis at a semi-fine scale with spatially explicit data

Creator:

Orrego, Sergio A.

Abstract:

This dissertation used land rent theory and an economic model of land-use conversion to examine the main drivers of the deforestation occurred in Antioquia,Colombia, between 1980 and 2000. Land-cover information at a semi-fine scale (1:25,000) obtained largely from aerial photography was employed to calculate deforestation. In addition, free international databases...
