The vast majority of animals rely on sex to maintain a diverse and healthy gene pool. Not so for the rotifer, a type of microscopic creature that lives in puddles and munches on pond scum. Bdelloid ...

A new study shows that humans and tiny aquatic animals known as rotifers have something important in common when it comes to sex. Barely visible without a microscope, rotifers eat algae and serve ...

Rotifers are now becoming a standard live feed for first-feeding larvae, because of their easy rearing protocol and improved growth and survival rate, compared with other fish feed, paramecia, and ...

WOODS HOLE, Mass. — In case you were wondering, Kristin Gribble is not a basher of fruit flies or roundworms. She wants to be clear: She bears no ill will toward those invertebrates so often studied ...

The choice to have sex has everything to do with location, at least for tiny freshwater creatures called rotifers. Rotifers can reproduce sexually or asexually, and the decision to go one way or ...

Rotifers have been the big wheels of the microscopic world for more than 300 years, so it's fitting that a rotifer's wheel-like head gets its turn in the photographic spotlight. An extreme close-up of ...

Climate change will alter the forces of predation and competition in temperate ectotherm food webs. This may increase local extinction rates, change the fate of invasions and impede species ...

THE WORLD’S fisheries are overexploited. One way to relieve pressure on them is to increase the yield of fish farms. And one way to do that is to improve the quality of the food fed to the livestock ...
