Local extinctions have cascading effects on ecosystem functions, yet little is known about the
potential for the rapid evolutionary change of species in human-modified scenarios. We …

Neotropical mammal diversity is currently threatened by several chronic human-induced
pressures. We compiled 1,029 contemporary mammal assemblages surveyed across the …

Biodiversity is organised into complex ecological networks of interacting species in local
ecosystems, but our knowledge about the effects of habitat fragmentation on such systems …

Recent global assessments have shown the limited coverage of protected areas across
tropical biotas, fuelling a growing interest in the potential conservation services provided by …

Aims We analyse here the variations in species composition and richness and the
geographic ranges of the tree species occurring in South American subtropical Atlantic and …

Defaunation, the loss or population decline of medium and large native vertebrates
represents a significant threat to the biodiversity of tropical ecosystems. Here we review the …

Tropical deforestation and forest fragmentation are among the most important biodiversity
conservation issues worldwide, yet local extinctions of millions of animal and plant …

North America has a diverse array of mammalian species. Model projections indicate
significant variations in future climate conditions of North America, and the habitats of …

Hunting affects a considerably greater area of the tropical forest biome than deforestation
and logging combined. Often even large remote protected areas are depleted of a …

Preserving large tracts of natural habitats is essential to maintain biodiversity. Nevertheless,
even large areas may still suffer from less “visible” impacts such as loss of ecological …
