The Global Extinction Crisis – species area relationships, habitat loss, and population dynamics

Conservation, ecology, Natural Science, ScienceMay 23, 2011

We are in the midst of a global extinction crisis. Biodiversity is in decline as species after speciesĀ disappear. SomeĀ estimatesĀ predict that up to 50% of species will be committed to extinction by 2050. Other estimates claim the current rate of extinction may be 10,000 times the background rate. Many ecologists and conservationists have declared the current […]
