Using water fleas, researchers investigate adaptive evolution

Researchers from The University of Texas at Arlington resurrected the preserved eggs of a shrimp-like crustacean to examine long-standing questions about adaptive evolution, reporting the results in the journal Proceedings ...

Disrupting key protein alters biological rhythms in water flea

Researchers from North Carolina State University have shown that the E75 protein is a key regulator of some biological rhythms through interactions with nitric oxide. Suppression of E75 results in longer molt cycles and reduced ...

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 ...

Salamanders chew with their palate

The Italian Crested Newt – Triturus carnifex – eats anything and everything it can overpower. Earthworms, mosquito larvae and water fleas are on its menu, but also snails, small fish and even its own offspring. A research ...

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 ...

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 ...
