The nutritional role of silver for the freshwater crustacean, Daphnia magna, was examined through four generations of deprivation. Silver inclusion in animal media was set at a nominal zero (employing chemicals of the highest available purity). Both

Daphnia pulex Leydig (Cladocera), reared in circumstances of strictly controlled trace element exposure, were deprived of zinc. When zinc was withheld from both their liquid medium and solid (algal) food, D. pulex survived for more than 20 consecutiv

When an algal diet is employed, or precipitation of dissolved inorganics during autoclaving is likely, or test circumstances introduce pH changes, addition of a buffer to daphnid culture or bioassay media is appropriate. Glycylglycine, employed in ou

For daphnids, the diatom Nitzschia frustulum is both a nutritionally desirable food and a source of essential organics not adequately provided by several green algae commonly fed daphnids in bioassays. Although a diet based on only one alga, Chlamydo

For intact daphnids reared in circumstances of controlled trace element exposure, one consequence of insufficient zinc (Zn) is an increased demand on the animal's pool of available selenium (Se). This demand is manifested by the type of cuticle deter

The purpose of this study was to develop a successful culturing system for Ceriodaphnia dubia/affinis. Seventeen different algal foods were offered to C. dubia/affinis, and their effect on fertility and longevity observed. The best single algal food

MS is a set of defined media. It is comprised of inorganics, plus crystalline vitamin B 12 and, usually, a glycylglycine buffer, which are dissolved in distilled-deionized water. Algal and animal media differ only in that algal media contain more pho

Cell-free filtrates of axenic or bacterized cultures of the dominant blue-green algae from a freshwater lake inhibited the growth of diatoms isolated from the same lake. Lake waters, collected during blue-green algal blooms, also inhibited diatom gro

Daphnia pulex de Geer and Daphnia magna Straus populations cannot be maintained in defined (sensu stricto) media containing less than 0.1 part per billion (ppb) of selenium. A concentration of 1 ppb is sufficient to satisfy minimal needs in otherwise
