| Abstract: | The reproductive bionomics of two Canadian sublittoral amphipods, Casco bigelowi and Leptocheirus pinguis, are compared in a Bay of Fundy estuary. Casco is semelparous and Leptocheirus iteroparous, although both have a biannual life history. The relatively high reproductive potential of each species, Casco with a reproductive potential of 12.5 and Leptocheirus with 25.5 young per year, is dictated by a combination of wave-caused sediment washout and prédation within the estuary. |
