HUMAN HEALTH AND ECOLOGICAL RISKS OF SOME HEAVY METALS IN Sarotherodon melanotheron FROM A TROPICAL LAGOON

Abstract Increasing contamination of aquatic environment as a result of indiscriminate discharge of solid wastes and effluents has become a global issue of environmental concern. There are harmful substances contained in the wastes and effluents which create a major problem on the quality of the Nigerian coastal water. This study evaluated the human health and […]

IMPACT OF MONA MONKEYS ON PLANTAIN FARMS IN AFIJIO LOCAL GOVERNMENT AREAS OF OYO STATE, NIGERIA

Abstract This study examines the impact of Mona monkeys (Cercopithecus mona) raiding plantain (Musa paradisiaca) farms in Afijio Local Government Area of Oyo State, Nigeria. Three towns were purposively selected for the study. Data was collected using in-depth interview by participatory rural approach methods with owners of farms frequently raided by the monkeys in the […]

FALL ARMYWORM, Spodoptera frugiperda OUTBREAK IN NIGERIA: IMPACTS AND MANAGEMENT ON MAIZE FIELDS – A REVIEW

Abstract The recent invasion of fall armyworm (FAW, Spodoptera frugiperda) on maize in Africa has threatened food security in Nigeria and across African region.   The arrival of fall armyworm in Nigeria since 2016 has significantly affected maize production and caused severe economic losses to farmers in the country. The spread of FAW in Nigeria cut […]

INFLUENCE OF NATURAL GROWTH REGULATORS ON THE GROWTH OF DIFFERENT CULM SIZES OF Bambusa vulgaris (SCHRAD.) J. C WEND

Abstract Exploitation of bamboo for numerous uses keeps on increasing and there have been observation of low percentage survival from culm cuttings propagation. This study therefore investigated effects of Natural Growth Regulators (NGRs) on the growth of different culm sizes of Bambusa vulgaris with aim to enhancing survival and growth of the species with the […]

ECOLOGICAL ASSESSMENT OF AIR POLLUTION TOLERANCE INDICES (APTI) OF ARBOREAL EPIPHYTES UNDER AMBIENT ENVIRONMENTAL CONDITION: A WINDOW FOR SELECTION OF BIOINDICATOR AS BIOMONITORING AGENT

Abstract The screening of plant species is of environmental significance hence their sensitivity as bioindicator as well as their tolerance as biomonitoring agent in air pollution mitigation have been established. The present research was aimed at evaluating the potential response of arboreal epiphytes as bioindicator under ambient condition, with the objective of identifying species that […]

ASSESSMENT OF HEAVY METAL CONTAMINATION IN PLANT SAMPLES OF OLD OYO NATIONAL PARK, SOUTHWEST, NIGERIA: A BASELINE STUDY

Abstract Heavy metal contamination may alter the chemical composition of plants with consequent effect on their growth and possible transmission of potential toxic metals to animals and humans along the food chain. The study was carried out to quantitatively assess the levels of heavy metals in plant species in Old Oyo National Park, Southwest, Nigeria. […]

VARIATION IN MORPHOMETRIC CHARACTERS OF Vitellaria paradoxa (C.F Gaertn) SEEDS IN RELATION TO GERMINATION AND SEEDLINGS BIOMASS

Abstract Seed morphological characteristics were examined on germination and early growth of Vitellaria paradoxa. Seeds were sourced from Eruwa, Saki and New-Bussa in the Derived, Southern Guinea and Northern Guinea Savanna ecological zones of Nigeria respectively and classified into three sizes: large (length ≥45.00 mm); medium (length 40.00 – 45.00 mm) and small (length ≤40.0 […]

ECOLOGICAL RISK OF CHEMICAL FRACTIONATION OF HEAVY METALS IN SEDIMENTS FROM OGBA RIVER, BENIN CITY, NIGERIA

Abstract Heavy metals have been recognized worldwide for their toxic effects in man and wildlife. The Ogba River in Benin City, Nigeria, has been reported to be contaminated to varied levels by heavy metals as a result of anthropogenic impact. However, there is paucity of scientific data on the chemical fractionation of such metals in […]

MANAGING ENVIRONMENT FROM BELOW: THE MATERIALITY OF COMMUNITY PARTICIPATION FOR ECOLOGICAL SUSTAINABILITY IN ZIMBABWE

Abstract There are growing global concerns about climate change and that resulted in environmental management becoming a global policy priority. The increasing focus placed on the environment globally, has shifted the responsibility from national governments to a more consensus based approach, where communities as environmental stakeholders have a role to participate in environmental management. The […]

SEEDLING GROWTH PERFORMANCE OF Khaya senegalensis (Welw.) C.DC UNDER DIFFERENT LIGHT INTENSITIES AND SOIL TEXTURAL CLASSES

Abstract Plant growth and development is influenced by environmental conditions such as light intensity, which refers to the total amount of light that plants receive and degree of brightness that plant is exposed for photosynthesis process and also soil texture control mineralization by influencing aeration moisture status. This study investigates seedling growth performance of Khaya […]
