Abstract

This paper describes preliminary results on the temporal organisation of foraging behaviour in the limpet Patella caerulea in the North Adriatic Sea. Limpet activity was monitored in the field using radio telemetry during three continuous 15-day recording periods in spring, summer and winter. The results showed greater activity during immersion or when splashed by waves compared to periods of emersion, and a general prevalence for activity during the daylight compared to night-time. Activity patterns varied between. study periods, indicating that individuals used. different tidal or diel phases according to the time of year, With the fraction of activity performed during immersion being greater during winter than during spring or summer. During winter sampling there was also an increase (although non-significant) in total activity compared to spring (increase = 8 1%) and summer (increase = 24%). The. results also demonstrate an increase in between-individual variability in the summertime compared to the winter or spring.
