Drought-mortality relationships for tropical forests

Drought-mortality relationships for tropical forests.

*The rich ecology of tropical forests is intimately tied to their moisture status. Multi-site syntheses can provide a macro-scale view of these linkages and their susceptibility to changing climates. Here, we report pan-tropical and regional-scale analyses of tree vulnerability to drought. *We assembled available data on tropical forest tree stem mortality before, during, and after recent droug...

Toward Trait-Based Mortality Models for Tropical Forests

Tree mortality in tropical forests is a complex ecological process for which modelling approaches need to be improved to better understand, and then predict, the evolution of tree mortality in response to global change. The mortality model introduced here computes an individual probability of dying for each tree in a community. The mortality model uses the ontogenetic stage of the tree because ...

Tropical Forests

To understand where and why tropical forests exist, one must begin with some essential facts of geography and climatic systems. By definition, ‘the tropics’ lie between 238N and 238S latitude, the area within which the sun lies directly overhead at some point in its seasonal progression. Thefluxof solar energywithin this region is high, due to the fact that incoming sunlight is projected at a 9...

Fragmentation and Tropical Forests

Model systems are needed to examine fragment area effects on food web structure where other factors are relatively constant. Human-induced fragmentation is typically associated with human activities, which may complicate interpretation of results from fragmentation studies. Forests on Hawai`i Island periodically experience a unique natural disturbance where lava flows into forests, leaving behi...
