Groundwater is described as the water found beneath the surface of the earth in underground streams and aquifers and has become popular as a source of drinking potable water in Nigeria due to its quality when compared to other water sources. The Electrical resistivity method was employed in Imakun Omi Community, a coastal town in Ogun Waterside Local government area of  Ogun State with the aim of determining the groundwater potential of the area. A total of twenty (20) Vertical Electrical Soundings (VES) points were carried out in the area using the Schlumberger configuration with maximum current electrode separation (AB) of 300m using the ABEM SAS 1000 Terrameter. The results obtained were interpreted quantitatively and qualitatively using partial curve matching and computer iteration programs WINRESIST and SURFER 11 for the interpretation from which the reflection coefficient was computed. The groundwater potential of the rock units were evaluated and  40% of the stations show  high yield, 50% of the stations show medium yield and 10% of the stations was observed to have low yield. The aquifer thicknesses are very thick with values ranging from 6.9 m to 79.3 m, hence an average of 43.1mand overburden thicknesses ranging from 9.7m to 96.5 m, with an average of 53.1m

The influence of humans on biodiversity at the genetic, species, community, and ecosystem levels is enormous. This is even more impactful on plant populations, which, being immobile, are at the mercy of their immediate environment. Digitaria horizontalis is a very common grass species in Benin City. Its ruderal nature accounts mostly for its widespread. The current study investigated the existence of possible genetic diversity of the grass in built environment in Benin City. Plant samples were randomly collected from 21 built environment locations within 6 Local Government Council Areas that make up Benin City. Test plants were allowed to acclimatize in experimental bowls and then allowed to grow for 4 weeks after which morphological characteristics were determined. Genetic diversity was determined by Random Amplification of Polymorphic DNA. Significant differences in plant height (33.0 – 59.0 cm) occurred when plants were compared based on location of collection. Changes in patterns of the association with weeds within the vicinity of the test plant was observed. The most prevalent plant species associated with the test plant was Pennisetum purpureum with a 12.18% prevalence. RAPD analysis using primer OPA 04 revealed a locus (about 600bp) that was absent in one or more of the locations with minimum disturbance. This 600pb fragment was however observed in most samples from highly built up and trampled environments. Primer OPA 03 showed monomorphic bands in 2 test samples with a band size of 400bp. It is therefore reported that there is an existence of the genetic diversity in a landscape of grass species (Digitaria horizontalis) found in different built environment in Benin City, Edo State, Nigeria.

Lam Apeng is a village with a majority of people living as farmers, which causes the need of water for agriculture is increasing. The water demand in this area continues to increase as the population increases, for various purposes. The objective of this study is to determine the distribution of the groundwater layer using the electrical resistivity method and to determine groundwater potential using hydraulic parameters. This research is conducted using 2 measurement line with a length of each line is 112 meters and distances of each electrode is 2 meters. The data invert using Res2Dinv software to obtain 2D subsurface lithology subsurface. At line 1, the aquifer (sand) layer is located in the second layer with a rock resistivity value of 12 Ωm - 18.6 Ωm at a depth of 8 m - 18 m. At line 2, the aquifer (sand) layer is also located in the second layer with a resistivity value of 4.6 Ωm - 18 Ωm at a depth of 5 m – 12 m. Based on the interpretation of the two measurement lines, it can be concluded that the type of aquifer in the research site is a semi unconfined aquifer. In this study, hydraulic parameters (hydraulic conductivity, longitudinal conductance, transverse resistance, and transmissivity) was calculated based on the resistivity value and the thickness of the aquifer layer. The average resistivity of the aquifer layer used is 15.3 Ωm and 11.3 Ωm, respectively for line 1 and line 2, indicating that the aquifer was moderately corrosive. Longitudinal conductance values are 0.65 Ω-1 and 0.62 Ω-1 which indicated moderate protective capacity. The transmissivity values are 6.78 m2/dayand 4.77 m2/day, which indicates that the designation in this area is low and the groundwater potential is local or only for personal consumption.
