Instar development rates of Diaptomus minutus (Copepoda: Calanoida) in a small lake in Quebec

A study of the life history of the calanoid copepod Diaptomus minutus Lilljeborg in C-22, a small lake of the Matamek River System, Quebec, demonstrated that instar duration times of the nauplii and younger copepodites in the major generation were considerably shorter than those reported elsewhere. It is hypothesized that these differences may be attributable to the abundance of nannoplankters characteristic of highly oligotrophic waters.
