Correlation between nematode communities with some environmental parameters in the Dai estuary, Ben Tre

Abstract

Free living nematode communities were investigated at the same time with some environmental parameters in the Cua Dai estuarine sediment, Ben Tre province. Our results showed that nematode densities, biodiversity and genera richness were quite high. Obtained data of nematode univariate, such as densities, genera richness, biodiversity and feeding type structure was applied statistical method to investigate significant different between sampling stations along the estuary. Remarkably, there is no nematode univariate showed significant correlation with salinity gradient but they did show with pH, coliform, NH₄⁺, PO₄^3-, chlorophyll a and percentage of silt in the sediment.
