European Bird Communities Move to Cooler Areas, but Mountain Ranges and Coastlines 'Control the Traffic'

A recent study shows that European bird communities have shifted northeastward in the past 30 years. These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast ...

New Research Finds That More Than 90% of Global Aquaculture Faces Substantial Risk from Environmental Change

Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark ...

Megalodon Was No Cold-Blooded Killer

How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the ...

How Coral Reefs Can Survive Climate Change

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine ...
