Paper and Works in progress: Assessment of the effects of palm oil effluent on the water quality and macroinvertebrate community structure of Ara River, Southwestern Nigeria.


My major discipline and research focus is Aquatic insect Ecology and Ecotoxicology. My contribution to knowledge was initiated with my research efforts on the faunal composition of the Order Trichoptera in waterbodies in Ile-Ife (Paper i). The study revealed that Hydropsychidae was the dominant and most diverse family. The fauna was found to be quantitatively and qualitatively richer in the wet season than in the dry season and this was attributed to the fact that the family shows a wide range of tolerance to climatic, physical and chemical conditions and is more tolerant to mild pollution of various kinds than most other Trichopteran species. My contribution to the review of the status of insect diversity conservation in Nigeria revealed that Nigeria ranked as the nation with the highest rate of forest loss in 2005 (paper iii). The need to provide sufficient baseline information on the taxonomy, species distribution and ecology of Nigerian insects at both eco-regional and national scales was proposed. My research on the community structure of aquatic macroinvertebrates in relation to the sediment characteristics of Osinmo Reservoir provided information on the ecological status of the reservoir, and also revealed the stability in the community structure of the macroinvertebrates irrespective of the seasonality with the abundance of pollution sensitive species also indicating that the reservoir was in pristine condition as at the time the study was carried out (paper vii). I have also been involved with investigations into the ecological status of some other water bodies within the South Western Nigeria by analyzing the macroinvertebrate assemblage and water quality and such studies             have provided useful information for the management practices of such waterbodies (papers vi, vii and ix).  My research efforts on the assessment of acute toxicity effects of soaps and  pesticides have also revealed that indiscriminate use of these chemicals have serious impact on the bionomics of aquatic insects (papers vi and xi).
