AbstractHeart rate variations of a population of the limpet Patella vutgata were monitored in the natural environment (Lough Hyne, southern Ireland) by non-invasive, optoelectronic recording. The heart rates of 145 limpets of different sizes, living on vertical and horizontal substrata, were measured both in air and water at different environmental temperatures, while the animals were inactive on their home scars. The heart rates of emersed, inactive limpets were positively related to air temperature and negatively related to limpet size. These relationships were similar for limpets on vertical and horizontal substrates. In contrast, no significant relationship between heart rate and temperature was found in submerged limpets, probably due to the narrow thermal range of the water during the study period During submersion, a significant negative relationship between heart rate and size was evident for limpets on vertical surfaces but not for limpets on horizontal surfaces. In general, submerged limpets had a higher heart rate, 1.16 times that of limpets exposed to air. Moreover, the heart rates of nine animals were recorded while they were moving and while inactive on their home scars. Active limpets had a faster heart rate, 1.6 times that of limpets resting on their home scars. The dependence of heart rate on environmental temperature, size, respiratory medium and activity, as observed in limpets on the shore, agrees well with laboratory data and with previous findings of the correlation of oxygen consumption with the same factors. Such in situ measurements may, therefore, prove useful in attempts to determine natural levels of energy expenditure in models on the behaviour of foraging molluscs.
