Pyhajarvi, large stocks of the planktivorous fish species vendace and smelt were accompanied by a reduction in cladoceran
biomass and the practical disappearance of larger (>0.
Waterbodies in Texas are particularly interesting with respect to species richness of their cladoceran
fauna because presence of endemic taxa and Neotropical species are expected in this region (De Melo and Hebert, 1994; Hebert and Finston, 1996).
In shallow lakes fewer typical pelagic cladoceran
species are present, except D.
Fulton & Paerl (1988) observed in their study that a rotifer's (Brachionus calyciflorus) ability to handle a non-toxic strain of Microcystis aeruginosa was superior to that of a cladoceran
The exotic cladoceran
, Daphnia lumholtzi Sars, possesses cyclomorphic features which are widely assumed to deter gape-limited predators.
Toxicity of 17a-ethynylestradiol and norethindrone, constituents of an oral contraceptive pill to the swimming and reproduction of cladoceran
Daphnia magna, with special reference to their synergetic effect.
The invading European cladoceran
Bythotrephes cederstroemi, previously reported in North America from the Great Lakes and inland lakes in Ontario and Minnesota, was found in diets of juvenile largemouth bass (Micropterus salmoides) from three Ohio reservoirs in the Ohio River drainage, representing a potential expansion of the range of this exotic species.
Optimization of differential display polymerase chain reaction as a bioindicator for the cladoceran
4 times per cladoceran
, almost 3 times per copepod, and 3.
The ratio of calanoid:cyclopoid copepods plus cladoceran
species was first used as a measure of trophic condition in the Great Lakes (Gannon & Stemberger 1978).
1 Are cladoceran
reproduction assays appropriate for characterizing chronic toxicity of all PPCPs?
