TL;DR: The extent of tropical forests and their rate of destruction and degradation through fragmentation remain poorly known as discussed by the authors, and past estimates of forest cover and deforestation have varied widely, and there is no consensus on the current state of the forest cover.

TL;DR: It is shown, in an analysis of wide taxonomic and geographic breadth and high spatial resolution, that multitaxonomic rather than single-taxon approaches are critical for identifying areas likely to promote the persistence of most species.

TL;DR: A comparison of the most recent epoch with previous periods shows that policies enacted in the late 1990s to promote forest conservation had no observable impact on reducing deforestation and that deforestation actually increased in some protected areas.

TL;DR: In this paper, the authors use generalized dissimilarity modeling (GDM) as a basis for estimating forest biodiversity remaining at different points in time, and predict that 9.1% of species in Madagascar have been committed to extinction from deforestation between 1950 and 2000.
