Der Grosse Augenblick und der Kreis der Zeithe residue from this extraction elicited positive responses in test fish. Dried residues showed 5 bands in thin-layer chromatograms, but only one band (R. 0.94), identified as cholesterol ester, contained the sexual attractant(s).

overhaul

Significance of Protein Kinase A in Cancerndividuals of small species are confined to portions of the reef. They are unable to produce enough eggs for effective long-range dispersal, and so they keep their vulnerable eggs and young out of the plankton until they are well developed enough to seek out and settle onto the appropriate habitat before dispersing.

Effects of alarm substance on schooling in the common shiner (,, Cyprinidae),between size of fish and their distance to the center of the school. Furthermore, the tendency to seek cover increased in the presence of Schreckstoff. The greater organization in school structure appears to be an adaptive response to aquatic predators, whereas increased cover seeking may be an adaptive response to aerial predators.

Attraction of zebrafish, ,, to isolated and partially purified chromatographic fractions,he residue from this extraction elicited positive responses in test fish. Dried residues showed 5 bands in thin-layer chromatograms, but only one band (R. 0.94), identified as cholesterol ester, contained the sexual attractant(s).
