From big and scared to small and brave - evolution has moved at lightning speed on a small island in the Koster Sea on the West coast of Sweden. The beach snail's rapid adaptation after a forced change of environment amazes researchers. In 30 years, it has changed both its appearance and behavior to survive.
Researchers have now established that the harbor seals in the Kosterhavet area are becoming increasingly scarce. Last year, only half of the females gave birth to pups. This is according to research from the University of Gothenburg, following this year's seal count. – We were very surprised. These low numbers cannot be dismissed year after year, says Karin Hårding, professor of zoological ecology at the University of Gothenburg and the leader of the project.
The unmanned underwater vehicle Ran has disappeared under a glacier in Antarctica. "It's a bit like looking for a needle in a haystack, but without even knowing where the haystack is," says Anna Wåhlin, project manager and professor at Gothenburg University, in a press release.
