Caption The common water flea, Daphnia pulex, will be used as a model organism to study how genetic function is influenced by manmade environmental stress at a population level in a course on ...

Eggs are clearly visible in the healthy water flea of the species Daphnia magna on the left. The infected water flea of the same species on the right has been castrated by the parasite and is no ...

Daphnia are tiny crustaceans, or "water fleas," that are extremely adaptable to their environment. This is due to their ...

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.

For this project, we conducted controlled laboratory experiments with zooplankton (water fleas, Daphnia magna), fish (fathead minnows, Pimephales promelas), and larval amphibians (gray treefrogs, Hyla ...

Environmental toxicologists, chemists and social scientists have identified three priorities for research into the impact of engineered nanoparticles on the environment. First, the choice of ...

The water fleas Daphnia are finding it harder to evade predators as CO₂ levels rise in the water. And in coral reefs, the colourful and pretty damselfish are losing their ability to learn who ...

Marine Biology 132: 1-8 Storz, Paul (1998) Phototaxis in water fleas (Daphnia magna) is differently influenced by visible and UV light. J Comp Physiol A 183: 709-717 Steeger, Wiemer, Freitag, Paul ...

Surely, then, such damaging potential warrants a tight and thorough regulation process? … Except how it currently works is to carry out individual studies on different species – one on fish, another ...
