Abstract
The saltmarsh isopod Sphaeroma rugicauda (Leach) is subjected to widespread diurnal and seasonal temperature fluctuations under natural conditions. Laboratory studies on its activity show that there is a relationship between behaviour activity and exposure temperature between 2.5° and 25°C. Although S. rugicauda has no complex metabolic adaptations, this isopod is able to maintain a rate of aerial oxygen consumption which is similar to that in water within the temperature range 5° to 25°C. The responses of S. rugicauda to changes in environmental temperature are discussed in relation to the seasonal microdistribution of the isopod in the salt-marsh habitat.
