Title Distribution, community structure and species succession of copepods from Cochin Backwaters
 
Creator Madhupratap, M
 
Description 1-8
Ecological aspects of copepods, the major group of zooplankton in Cochin Backwaters, Kerala, India, based on year round collections from its lower reaches are presented. Truly estuarine and estuarine and marine species form the bulk of the composition along with a couple of euryhaline marine species. Most of the marine species are only stragglers into the estuary. Variations in the abundance are compared with estuaries elsewhere. Based on the spatial and temporal abundance various species of copepoda fall into different groups which together dovetail to project their overall distribution in the estuary. Species of the family Acartiidae dominate the counts. Higher abundance of copepods are recorded during the saline summer period. The system remains practically virgin and underexploited at secondary level during low saline monsoonal period. Invasion of various species into the estuary and their succession begin by postmonsoon followed by diversification and habitat selections in premonsoon. Community structure and variations in diversity trends can be explained to some extent based on salinity distribution. Broadly, 3 serial stages can be recognised in the successional sequence consisting of high saline, low saline and medium saline species.
