Seasonal Respiratory Variation and Acclimation in the Pea Clam, Pisidium Walkeri Sterki
Comparative Biochemistry and Physiology -- Part A: Physiology
1. Seasonal respiratory variation at field temperatures and at 10° and 20°C are presented for field acclimated clams. Values are presented as QO2s based on "shell-free" tissue dry weight and "shell-free" tissue N2.
2. Q10 values are presented for all seasons with winter and summer values of about one and three respectively.
3. No size rate differences were found for measurements of oxygen consumption.
4. The seasonal acclimation pattern is complex with the data of early spring indicating Precht's Type I pattern of over-compensation for the over-wintering generation and some of the summer-fall data suggesting Precht's Type V "reverse" acclimation for the summer generation. Seasonal acclimation is discussed in an ecological-environmental context. © 1976.
