The comparisons of the 50% inhibitory concentration (IC50) obtained from this work to rainbow trout assay daphnid
(Daphnia magna) immobilized urease papain bromelain and Microtox(R) toxicity data are shown in Table
2001), who found that the exposure of Daphnia magna to propiconazole interferes with the later stages of daphnid
embryonic development, and that the toxicity was manifested largely via maternal exposure to the fungicide.
luhmholtzi may provide a relative advantage to fishes with mouth morphologies that allow consumption of this daphnid
reproduction and development will be presented and the use of
These salmonids would affect species number by feeding on large-bodied species such as daphnid
cladocerans and calanoid copepods (Modenutti et al.
For example, freshwater Arctic daphnid
crustaceans are exposed to high levels of UVR during summer, and synthezise and accumulate substances which provide protection against high levels of UVR.

Freshwater organisms (SARs and analogues): acute toxicity to fish, daphnid
, and green algal species; fish, daphnid
, and green algal chronic values (ChV)
To test for interspecific differences, I compared the growth of five daphnid
species feeding in the same experimental vessels.
Broods of female offspring are produced under favorable environmental conditions, and the daphnid
population expands through asexual (parthenogenic) reproduction.
For at least the past three decades, the smaller Daphnia galeata mendotae and the larger Daphnia pulicaria have alternated as the numerically dominant daphnid
