Temperature-dependent energy partitioning in the benthic copepods acanthocyclops-viridis and macrocyclops-albidu

Copepods from Esthwaite Water, English Lake District, were investigated at a range of temperatures within the normal environmental range (5-20°C), in animals fed an excess of the ciliated protozoan Paramecium caudatum. Feeding rate increased with elevated temperature, while longevity, development time, adult size, clutch size, and interclutch period decreased. Temperature had a marked effect on the pattern of energy partitioning into reproduction: increasing temperature moved the balance towards reproduction. -from Authors
