Ecology of the coexisting copepod species in Cochin backwaters

M. Madhupratap


Association between the common copepod species of Cochin backwaters were analysed. Grouping of the low saline and medium saline species generally stood separate from the high saline species. A high degree of correlation was found among most of the high saline species. The degree of ecological differentiation between them was not very clear. Probably the peculiarities of the estuarine system allowed them to survive as competitors, since it is conceivable that the competing species expand their overlapping niches, in space with time because of salinity incursion. The elimination is automatically brought about by monsoonal change before severity in competition occurs
