Welcome to the Tropical Large-Scale Ecology Lab (TLSELab) at the University of Puerto Rico-Rio Piedras. Tropical landscapes are complex, and we are interested in understanding the origin of this complexity, as well as its consequences for the diversity and functioning of ecosystems. We explicitly recognize the role of space in the organization of ecosytems whether at local or regional scales, and the possibility for interactions between them largely facilitaded by the increasing influence of humans on landscpes

Our main goals are to:

Contribute to the theoretical foundations of the field of Landscape Ecology and Macroecology.

Contribute tools and techniques for the study of landscapes, ecosytem processes, and plant and animal assemblages at large scales.

Apply this knowledge to the conservation, management, and restoration of tropical landscapes.



We have received good news about a couple of proposals that we submitted during the last year. Two of these will allow us to extend our work on landslides in the Sierra de Las Minas of Guatemala and the Central Mountains of Puerto Rico whereas a third one will help us with our project that examines temperature effects on the developmental trajectories of coqui frogs.


Diana Delgado completed her Ph.D. this past summer. Her thesis entitled "Disentangling Vine-invaded Tropical Landscapes - from Individual Vine Patches to Vine Networks" combines numerous approaches to uncover vine invasions in landscapes undergoing agricultural de- intensification.
