...Andrew E. Christie; Matthew D. McCoole Summary The cladoceran crustacean Daphnia pulex has served as a standard organism for aquatic toxicity testing for decades. The model organism status of D. pulex rests largely on its remarkable ability to rapidly adapt morphologically, physiologically...

...Matthew D. McCoole; Kevin N. Baer; Andrew E. Christie SUMMARY Daphnia magna and Daphnia pulex are well-established model organisms in the fields of ecotoxicology and toxicogenomics. Among the many assays used for determining the effects of environmental and anthropogenic stressors on these animals...

...Syuhei Ban; Hideaki Tenma; Tsukasa Mori; Kinya Nishimura SUMMARY Daphnia pulex were reared in 50 ml flasks, each containing 1, 20 or 40 individuals, which were serially connected with a 20-μm mesh screens between, in order to examine the effect of physical interference due to crowding on shifts...

...Rudolf Schwind ABSTRACT When Daphnia pulex are presented on one side of their visual field with diffuse, large-area linearly polarized light with a horizontal e-vector and on the other side of their visual field with large-area polarized light with a lower degree of polarization, they swim towards...

...Howard I. Browman; Iñigo Novales-Flamarique; Craig W. Hawryshyn ABSTRACT We tested the hypothesis that ultraviolet photoreception contributes to prey search in small juvenile rainbow trout ( Oncorhynchus mykiss ) and pumpkinseed sunfish ( Lepomis gibbosus ) while foraging on Daphnia pulex . Small...
