Circadian locomotor activity in freshwater decapods: An ecological approach

Circadian rhythms of locomotor activity shown by freshwater decapods display different patterns among crayfish, Procambarus, and crabs, when exposed to artificial light-dark cycles. Crayfish are mainly nocturnal while a crepuscular activity is observed in crabs of the genus Pseudothelphusa. In const...

Crayfish are mainly nocturnal while a crepuscular activity is observed in crabs of the genus Pseudothelphusa. In constant darkness, free running rhythms are displayed in unimodal or bimodal patterns by crayfish Procambarushowever, Pseudothelphusa continues to show bimodal rhythms. The many studies using locomotor activity indicate that the rhythm in freshwater crabs is circadian in nature, but that a multioscillatory system may be controlling the overt rhythm. In the present study, the implications of different locomotor activity patterns are analyzed in selected freshwater decapods with regard to the interactions between light and the organisms. Crabs and crayfish are commonly found in similar habitats, often sharing the same environmenthowever, different patterns of locomotor activity as well as different sensitivities of the bouts of activity with regard to entrainment by light, indicate that distinct temporal niches may exist that result in temporal exclusion or low competition.2011-01-22T10:27:17Z2011-01-22T10:27:17Z2004info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article0929-1016http://hdl.handle.net/11154/2415172210.1080/0929101041233131324135(40575):69-78reponame:Sistema de Información de la Facultad de Ciencias, UNAMinstname:Universidad Nacional Autónoma de Méxicoinstacron:UNAMenBiological Rhythm Researchinfo:eu-repo/semantics/openAccessoai:repositorio.fciencias.unam.mx:11154/24152025-09-17T19:21:01Z
