The parthenogenetic marbled crayfish (Procambarus spec.) has recently been introduced as a new preparation for neuroethological studies. Since isogeneity apparently limits inter-individual variation, this otherwise typical decapod species may be especially valuable for circadian studies. Locomotor activity of isolated marbled crayfish and agonistic activity of small social groups maintain circadian rhythmicity in constant darkness. As potential signals of circadian time information, levels of… CONTINUE READING
