This study examined the hydrochemistry of surface water along the River-Rima floodplain *** sampling locations were purposively selected,and,in each point,three samples were taken from surface water(river).The sampling was repeated after 20 ***,a total of 30 samples were *** samples obtained were subjected to laboratory *** revealed that BOD,TDS,Mg2+,and Fe3+are above the World Health Organization(WHO)and Standard Organization of Nigeria(SON)reference guidelines for drinking water *** detected from the coliform bacteriological analysis include Enterobacter aerogene,Escherichia coli,and Citrobacter freundii with most of the samples showing coliform bacteria growth above the SON standard for drinking ***,the water in the River-Rima floodplain of the Wamakko area is of low quality and unsafe for *** of principal component analysis(PCA)revealed external influences such as pollutant wash off and rock weathering as controls on hydrochemistry of surface *** is some indication of anthropogenic inputs(Cl-,NO3-,and PO42-)based on hierarchical cluster *** including Cl-,NO3-,and PO42-are increasingly added into surface water from human activities,mainly agriculture,and municipal sewage.

Nigeria is an Afrotropical region with considerable ecological heterogeneity and levels of biotic *** its vertebrate fauna,reptiles have broad distributions,thus,they constitute a compelling system for assessing the impact of ecological variation and geographic isolation on species *** red-headed rock agama,Agama agama,lives in a wide range of habitats and,thus,it may show genetic structuring and ***,we tested the hypothesis that ecology affects its genetic structure and population *** inference phylogenetic analysis of a mitochondrial DNA(mtDNA)gene recovered four well-supported matrilines with strong evidence of genetic structuring consistent with eco-geographic *** differences among populations based on the mtDNA also correlated with geographic distance. The ecologicalniche model for the matrilines had a good fit and robust performance. Population divergence alongthe environmental axes was associated with climatic conditions, and temperature ranked highestamong all environmental variables for forest specialists, while precipitation ranked highest for theforest/derived savanna, and savanna specialists. Our results cannot reject the hypothesis that nicheconservatism promotes geographic isolation of the western populations of Nigerian A. ***, ecological gradients and geographic isolation impact the genetic structure and population divergenceof the lizards. This species might be facing threats due to recent habitat fragmentation,especially in western Nigeria. Conservation actions appear necessary.
