A new study looks at how natural selection works more subtly than previously believed while an organism is in a stable ...

A type of zooplankton, Daphnia pulex (a.k.a. the water flea) is a microscopic crustacean whose unique reproduction habits make it the perfect species for studying evolution and natural selection.

The diversity of plant community types provides habitat for a variety of wildlife species ranging from mice to moose, butterflies to bats, and daphnia to dragonflies. An array of communities ...

For instance, organisms including aphids and daphnia reproduce asexually when resources are abundant and switch to sex only at the end of the season, when the potential for asexual reproduction is ...

Researchers at Lund University in Sweden have investigated the effects of nanoplastic on aquatic life in lakes and rivers.

This microscopic animal, known as a water flea or Daphnia pulex, generates genetic variation in a bizarre way, according to a new paper in the journal Proceedings of the National Academy of Sciences.

For example, some species of zooplankton (such as the crustacean Daphnia) have low body N:P ratio in their biomass while others (such as copepods) have high N:P ratio. Theoretical models ...

Daphnia magna. Despite their tiny size, these creatures occupy an important place in the food web and can tell us a lot about how the environment is faring. Because many of the key biological ...

A reliable filtration system is the cornerstone of a healthy aquarium. By continuously circulating and purifying the water, a filter removes debris, ammonia, and harmful bacteria. Betta fish are known ...
