Feeding pet fish may look simple, but it is one of the most important tasks for keeping them healthy and active. Many new ...

Water fleas of the genus Daphnia detect via chemical substances if their predators, namely Chaoborus larvae, are hunting in their vicinity. If so, they generate defenses that make them more ...

Acclimation of the waterflea Daphnia magna Straus (Crustacea: Cladocera) at 2 o to 12 o C above their habitat temperature (16 o C) ... embryos, larvae, and young adults.

In fact Daphnia have an astonishingly large number of genes. "We count more than 31,000 genes," says Colbourne. By comparison, the human genome has more like 23,000 genes. If Guinness tracks such ...

In addition to eating mosquito larvae, mosquitofish prey on other insect larvae, amphibian larvae, and zooplankton such as Daphnia, tiny crustaceans that graze on algae in freshwater ecosystems.

Mosquitofish populations with more females have greater ecological impact. by University of California - Santa CruzUniversity of California - Santa Cruz ...

Maternal control of diapause has been reported for insects and mites 7; the main factors in the maternal environment triggering the developmental switch in larvae are photoperiod and temperature 10.

Dragonfly larvae play a vital role in aquatic ecosystems. As predators, they regulate populations of smaller aquatic animals, while serving as prey for fish, amphibians, and other species.

Now that the Daphnia genome is published, we have a better understanding of how an animal’s environment impacts cellular machinery. Reference: John K. Colbourne, et al. (2011) The Ecoresponsive Genome ...

The common water flea - Daphnia pulex - is the first crustacean to have a blueprint made showing the sequence of chemicals that make up genetic code, or genome.
