Urban pollution is increasing at an alarming rate within the catchments of forested riverine systems in sub-Saharan Africa, Nigeria inclusive. Assessing impact Niger Delta region still use physico-chemical variables and biota-based assemblage. In covering this important gap freshwater biomonitoring, we developed a macroinvertebrate-based multimetric index (MMI) that would be useful monitoring, assessing, managing sites affected by urban pollution. We collected macroinvertebrates samples...
Africa harbours about a third of the world’s largest natural resource reserves mineral such as gold and diamonds. These vast in are essential to continent's development modern industrial society. However, these minerals, including gold, often illegally mined by locals which leads biodiversity loss groundwater surface water contamination. In present study, we assess impact illegal mining (i.e., panning) other anthropogenic activities on distribution patterns macroinvertebrate traits River...
This study aims to assess the vulnerability and tolerance levels of macroinvertebrate functional feeding groups (FFGs) in forested streams draining urban areas Niger Delta. It contributes our understanding how human activities affect freshwater ecosystems. Between 2008 2012, we conducted monthly measurements physicochemical variables collected macroinvertebrates. We categorised sampling sites into three based on disturbance levels: least impacted (LIS), moderately (MIS), heavily (HIS)....
The ecological health of River Ringim, Jigawa State, northwestern Nigeria was assessed between November 2018 and March 2019. Key physico-chemical variables alongside macroinvertebrates assemblage were used to achieve the aim study. result showed that four stations sampled relatively perturbed judging from high values turbidity, nitrate, phosphate, BOD, TDS, EC. Twelve (12) taxa 365 individuals recorded in entire study period five months, confirming deteriorating state river system. Hemiptera...
Measuring the level of degradation in riverine systems is paramount to assess their current health status. In this study we categorized sites and macroinvertebrate taxa into pollution biological categories, respectively. Sites categorization was done for four sites, while 12 were biologically River Ringim, North-western Nigeria. The principal component analysis constructed showed that physico-chemical variables such as total dissolved solids, conductivity pH positively associated with site 2...
