Parasites often cause changes in the growth and reproduction of their hosts. For example, during parasitic infections, tiny algae-eating crustaceans known as water fleas sometimes become sterile and ...

When the water flea senses predators in its environment, it suits up, growing tail spines, a pointy helmet and other armor. Now, researchers have sequenced the genome of the water flea, providing ...

Berkeley -- A new study led by researchers at the University of California, Berkeley, identifies specific gene expression changes in a species of water flea in response to contaminants, lending new ...

The water flea species Daphnia pulex is barely more than a millimeter long, is completely translucent, has no clear divisions between their various body parts…and has the largest genome of any animal ...

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 numbers of offspring in the water ...

With significant funding from the National Institutes of Health (NIH), a researcher at The University of Texas at Arlington is investigating fundamental biological processes that lead to fertility ...

Biologists sized up an unlikely natural phenomenon: when parasitism actually causes the number of hosts to increase, an effect known as a hydra effect. A study of common water fleas and their fungal ...
