Locomotor activity rhythms in talitrids from Mediterranean coastal ecosystems. Part I Tunisian case

A comparative study was conducted on activity rhythms of some talitrid species from Mediterranean coastal wetlands, particularly sandy beaches and coastal lagoon banks. Sympatric species and populations of the same species from different coasts were compared across Tunisian and Italian coasts. The same recording methods were used under constant conditions to highlight the main characteristics of the endogenous rhythms of the selected species and their variation. We present here a general introduction of the subject and the Tunisian case.
