EFFECTS OF MAGNETIC SALINE WATER APPLICATION FOR IMPROVING PHYSIOLOGICAL PARAMETERS OF TOMATO (Solanum lycopersicum) SEEDLINGS
Abstract Among the main environmental problems in arid and semi arid regions is the shortage of freshwater. To overcome this problem, lower quality-water, such as saline groundwater, is widely used. The use of saline water after magnetization could be a solution of the problem of water scarcity. This study examines the effects of water magnetic […]
SPATIAL CHARACTERIZATION OF GROUNDWATER QUALITY AS INFLUENCED BY WASTE DUMPS IN IBADAN METROPOLIS USING GIS MAPPING
Abstract Inefficient management of landfills and dumpsites for waste disposal is a major problem in Nigeria. Leachates and pollutants from these dumpsites have been known to contribute to the pollution of groundwater systems. The extents of pollution however are poorly quantified since the flow of pollutants continues below earth surface. The use of GIS mapping […]

ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF SOME NIGERIAN GREEN LEAFY VEGETABLES
Abstract This study evaluated the antioxidant and antimicrobial properties of Piper guineense, Ocimum gratissimum, Murraya koenigii and Gongronema latifolium leave extracts using ethanol, petroleum-ether and aqueous media. The scavenging activities of the extracts was measured with free radical 2, 2-diphenyl-1-picrylhydrazyl, flavonoid and phenolic contents were assessed by spectrophotometry while, gas chromatographic flame ionization detector was […]
PLANT DIVERSITY ON MOUNTAIN SITE; A CASE STUDY OF IDANRE HILL, ONDO STATE, NIGERIA
Abstract An investigation of the plant diversity of Idanre Hill was carried out using quadrant sampling technique and an extensive assessment of plant species found along different gradients namely, mountain top, midpoint and foothill. Quadrat size of 10m2 was randomly placed in 10 points on each elevation, followed by qualitative and quantitative vegetation description. Life […]
SPECIES RICHNESS AND DIETS OF BATS FROM TWO SITES IN SOUTH-WEST, NIGERIA
Abstract Information pertaining to bat species diversity, ecology and distribution is grossly inadequate and sparse. This study examines bat species richness and diets of some bats in two reserves in Nigeria. Bats were trapped using mist nets from 1800hrs to 2300hrs for 20 nights at each site. Faecal samples released by captured bats held in […]
