Flooding Induced Occurrence of Terrestrial Nematode Species and Genera in the Benthos of River Nun, Niger Delta

Abstract

Aims: To investigate; the effects of flooding and dredging on the nematode community composition in River Nun, Niger Delta, Nigeria. Study Design: The study is a survey using River Nun as a case study. Place and Duration of Study: Study area is a section of River Nun in Bayelsa State, Niger Delta, Nigeria, Samples were collected for 30 days. Methodology: Eckmann’s grab was used in collecting samples at depths; 0-10cm and 10-20cm from nine designated collection points (A x – Gx) along the river course. Nematodes were extracted from the sediment by the use of the modified Baermann’s extraction method. Identification was by
