The following mechanisms have been suggested to explain the coexistence of different Diaptomus species: vertical segregation, seasonal separation, and size differences. Three species of Diaptomus (D. minutus, D. oregonensis, and D. sanguineus, in order of increasing size) occur in Clarke Lake, Ontario. D. minutus was vertically separated from D. sanguineus, and there was a distinct size difference between the two. D. minutus and D. oregonensis showed different seasonal maxima and were separated by size differences. D. sanguineus and D. oregonensis were separated vertically and had different seasonal maxima. A combination of two mechanisms allows coexistence of each of the three Diaptomus species‐pairs in Clarke Lake.
