Factors behind past lemur species extinctions put surviving species in 'ecological retreat'
New research out today on the long-term impact of species extinctions suggests that the disappearance of one species does not necessarily allow remaining competitor species to thrive by filling now-empty niches.

Forest
A forest is an area with a high density of trees. There are many definitions of a forest, based on the various criteria. These plant communities presently cover approximately 9.4% of the Earth's surface (or 30% of total land area) in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Although a forest is classified primarily by trees a forest ecosystem is defined intrinsically with additional species such as fungi. A woodland, with more open space between trees, is ecologically distinct from a forest.
