Researchers studying plants, ants, birds, dung beetles and orchid bees in the Brazilian Amazon have found clear evidence that deforestation causes drastic loss of tropical forest biodiversity.
Humans depend on high levels of ecosystem biodiversity, but due to climate change and changes in land use, biodiversity loss is now greater than at any time in human history. Five University of Alberta researchers, including ...
New mathematics model shows that as the fish diversity of complex marine food webs declines, fish production resists the change, masking ultimate rapid loss
There is no longer any doubt: We are entering a mass extinction that threatens humanity's existence.
Of the 201 bird and mammal species that call northwest Alaska's arctic and subarctic region their home, 195 of them—or, roughly, 97 percent—could experience some form of habitat loss or gain stemming from climate change, ...
One of the first studies to map the impact of deforestation on biodiversity across entire regions of the Amazon has found a clear 'threshold' for forest cover below which species loss becomes more rapid and widespread.
A new University of Toronto study may force scientists to rethink what is behind the mass extinction of amphibians occurring worldwide in the face of climate change, disease and habitat loss.
The absence of teeth or "edentulism" has evolved on multiple occasions within vertebrates including birds, turtles, and a few groups of mammals such as anteaters, baleen whales and pangolins. Where early birds are concerned, ...
Bee populations have declined in recent decades mainly due to a loss of biodiversity causing the disappearance of their favorite pollinating plants, according to a study published Monday.
A UN conference on preserving the earth's dwindling resources opened Monday with grim warnings that the depletion of natural habitats and species was outpacing efforts to protect them.
