DIVERSITY AND DISTRIBUTION OF VASCULAR PLANTS IN CHARANCHI LOCAL GOVERNMENT AREA, KATSINA STATE, NIGERIA AND THEIR MEDICINAL IMPORTANCE

Abstract This study was conducted in Charanchi local Government area (LGA), Katsina State, to evaluate the floristic composition and diversity of vascular plants in the study area and to document their ethnomedicinal uses. Five sites were randomly selected and five quadrants were established in each site. Plant species in each of the site were identified […]

ECOLOGICAL IMPACT OF GAS FLARING FROM THE KADUNA REFINERY AND PETROCHEMICAL INDUSTRY (KRPC) ON FLORISTIC DIVERSITY IN KADUNA NORTHERN GUINEA SAVANNA ECO-REGION OF NIGERIA

Abstract Ecological   impact of gas flaring from Kaduna refinery and petrochemical industry on floristic composition in Kaduna Northern Guinea Savanna Eco-region of Nigeria where data on upshot of gas flaring on floristic diversity are limited was studied. A total of six (6) plots of 50m x 50m replicated three (3) times were laid in each […]

ADAPTATION OF FIELD-BASED ECOLOGICAL HEALTH ASSESSMENT PROTOCOL FOR CENTRAL AND SOUTH EASTERN HIGHLAND RIVERS IN ETHIOPIA

Abstract Rapid bioassessment protocols have been developed as inexpensive monitoring tools to assess the health of streams, rivers and lakes. The present study was conducted to adapt macroinvertebrate-based field protocol for assessing the ecological health of streams and rivers in the central and south-eastern highlands of Ethiopia. Abiotic and biotic data were collected from 154 […]

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 […]
