wFleaBase: the Daphnia genome database

wFleaBase is a database with the necessary infrastructure to curate, archive and share genetic, molecular and functional genomic data and protocols for an emerging model organism, the microcrustacean Daphnia. Commonly known as the water-flea, Daphnia's ecological merit is unequaled among metazoan...

Queen's University biologists find new environmental threat in North American lakes

...searchers examined a water flea, Daphnia, known to be a key component of many aquatic foodwebs. Having identified the calcium levels that would damage daphnia in a laboratory setting, they worked with government scientists to assemble hundreds of "water quality time series" from across the province, explains...

Reservoirs may accelerate the spread of invasive aquatic species, researchers say

...d brackish habitats adapt to fresh water. Several invasive species are suspected to have benefited from the use of reservoirs as avenues, including daphnia lumholtzi, a water flea from the Old World tropics, and the copepod Eurytemora affinis. Some evidence indicates that the spread of zebra mussels, an e...

Parthenogenesis

...ernate between the sexual and assexual strategies, an ability known as heterogamy , depending on conditions. For example, the freshwater crustacean daphnia reproduces by parthenogenesis in the spring to rapidly populate ponds, then switches to sexual reproduction as the intensity of competition and pre...
