Distribution and current trend of polar bear subpopulations throughout the circumpolar Arctic
Polar bears occur in 19 relatively discrete subpopulations with an estimated worldwide abundance of 20,000– 25,000 animals. Our knowledge of the status and trend of each subpopulation varies due to availability, reliabil...

Comb-jelly (Mnemiopsis leidyi) spreading through the Caspian Sea (invasive species)
The comb jelly (Mnemiopsis leidyi) is well adapted to the habitat (salinity, temperature, and food range) and reproduces faster than endemic species. As it eats the same food as them, it has had a drastic effect on their...
