Population dynamics of marine copepods: the importance of genetic variation
Considerable genetic variation for demographic and other biological traits related to fitness exists in natural populations of marine planktonic copepods. Theory predicts that with large amounts of genetic variation the potential exists for rapid evolutionary change in response to changing environmental conditions. The aim of this research was to evaluate the potential evolutionary (i.e., genetic) response of the calanoid copepod, Labidocera aestiva to environmental change. Major genetic differences were observed between two laboratory lines that were initiated from the same pool of eggs and subsequently reared under similar conditions. The divergence is attributed to the small size of the founding populations, and possibly selection. Evidence for seasonal selection occurring in the field is reported and the significance of these findings is discussed in regard to the population dynamics of copepods.
