Invasive waterflea can change ecosystems in the Bothnian Bay

The highly bioinvasive water flea, Cercopagis pengoi, has spread from the Caspian Sea to greater parts of the Baltic Sea. In the Bothnian Bay, it seems to meet a barrier in the area between the Bothnian Sea and the Bothnian ...

A method for predicting the impact of global warming on disease

Scientists have devised a method for predicting how rising global temperatures are likely to affect the severity of diseases mediated by parasites. Their method can be applied widely to different host-pathogen combinations ...

Scientists reveal how water fleas settled during the Ice Age

A new study shows that the roots used by three close species of microscopic Daphnia crustaceans to settle across the territory of Northern Eurasia differed greatly. The findings shed light on how continental freshwater fauna ...

Water flea can smell fish and dive into the dark for protection

Water fleas, or Daphnia, ensure their survival by reacting to a signal substance of their predators (fish) with flight. The zoologist Meike Anika Hahn from Professor Dr. Eric von Elert's research group at the University of ...
