Habitat conversion and global avian biodiversity loss.
The magnitude of the impacts of human activities on global biodiversity has been documented at several organizational levels. However, although there have been numerous studies of the effects of local-scale changes in land use (e.g. logging) on the abundance of groups of organisms, broader continental or global-scale analyses addressing the same basic issues remain largely wanting. None the les...
متن کاملInvasive predators and global biodiversity loss.
Invasive species threaten biodiversity globally, and invasive mammalian predators are particularly damaging, having contributed to considerable species decline and extinction. We provide a global metaanalysis of these impacts and reveal their full extent. Invasive predators are implicated in 87 bird, 45 mammal, and 10 reptile species extinctions-58% of these groups' contemporary extinctions wor...

متن کاملGlobal biodiversity loss from tropical deforestation.
Tropical forests are incredibly biodiverse; they support at least two-thirds of the world’s biodiversity (1) despite covering less than 10% of Earth’s land surface (2). Unfortunately, prospects for tropical forests and the biodiversity therein are becoming increasingly bleak owing to unabated deforestation and forest alteration (3) that stem from human activities such as logging, hunting, agric...
متن کاملUrban expansion as a driver of biodiversity loss: Integrating biodiversity in urban planning in African context
Africa has high biodiversity and is rapidly urbanizing. However, there is limited understanding of how urban expansion in Africa is likely to affect its habitats and biodiversity. Little urban ecological research has been done in Africa. This study needs to think ahead as Africa move into the “urban age” it is critical to inform the public on the importance of urban environment...
