  • proper n. A taxonomic genus within the family Daphniidae — the water fleas.


Sorry, no etymologies found.


  • In 1999 Hairston and colleagues published a paper in Nature that described how 40-year-old resurrected eggs could answer whether tiny crustaceans called Daphnia in central Europe's Lake Constance had evolved to survive rising levels of toxic cyanobacteria, known as blue-green algae.


  • As a treat, you might also like to offer some frozen foods such as Daphnia, bloodworms or maybe a couple of squashed frozen peas.

    Practical Fishkeeping

  • Lake trout ( '' Salvelinus namaycush '') play a key role controlling populations of zooplankton ( '' Daphnia '' spp.), snails ( '' Lymnaea elodes ''), and slimy sculpin ( '' Cottus cognatus '').

  • For example, in the freshwater cladoceran Daphnia spp., growth rates are correlated with the concentration of eicosapentaenoic acid in the water column [43].

    Effects of changes in ultraviolet radiation in the Arctic

  • Lake trout (Salvelinus namaycush) play a key role controlling populations of zooplankton (Daphnia spp.), snails (Lymnaea elodes), and slimy sculpin (Cottus cognatus).

    Human impacts on the biodiversity of the Arctic

  • Mesocosm studies by Beisner et al. [34], which investigated the influence of increasing temperature and food chain length on plankton predator – prey dynamics, showed that the predator – prey system is destabilized at higher temperatures (i.e., the macrozooplankton herbivore Daphnia pulex always became extinct), irrespective of the complexity of the food web (i.e., whether a two - or three-level food web was involved).

    Changes in aquatic biota and ecosystem structure and function in the Arctic

  • I like the idea that Daphnia exist, that they do pretty much everything I do except maybe keep a blog, and that their existence is both absolutely incomprehensible in human terms yet makes perfect sense beyond our artificial sphere.

    I heart Daphnia

    I heart Daphnia

  • There's a disconnect between AP Biology and watching fish bounce around in the suddenly warming waters the mudhole just yards away from our classroom, chasing Daphnia.

  • Inside we discussed a lab that measures the heart rates of Daphnia at different temperatures.
