Abstract Surface water is progressively subjected to stress as a result of anthropogenic activities. Systematic observation and characterization of anthropogenic activities along Molo River was done in 2014 to evaluate their effects on surface water quality. Portable GPS receiver was used to identify geographic locations of 23 sites purposively selected; based on their relative positions […]

AN ANALYSIS OF ADHERENCE TO PRECAUTIONS IN HERBICIDE APPLICATION FOR WEED CONTROL IN SELECTED CITIES OF SOUTHWEST NIGERIA
Abstract Unplanned urbanization and development have created spaces for weeds which cause several problems, making streets and built areas unattractive. The use of herbicides in controlling weeds in these areas has become the vogue in recent times. This is done without considering the attendant health effects on human and the environment. This study analyzed precautionary […]
ASSESSMENT OF PHENOTYPIC TRAITS OF Archachatina marginata marginata SNAILS IN THE DERIVED SAVANNAH ZONE OF OGUN STATE, NIGERIA
