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 […]

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 […]

GREENHOUSE EVALUATION OF Mansonia altissima ACHEV. SEEDLINGS AS AFFECTED BY MYCORRHIZA, FERTILIZER AND WATERING REGIME

Abstract A greenhouse investigation was conducted to determine the effect of arbuscular mycorrhiza, N. P. K fertilizer and moisture supply on Mansonia altissima seedlings. The experiment was 3x3x3 factorial experiment in completely randomized design with each of factor has 3 levels and was replicated 5 times. Application of arbscular mycorriza does not have significant effect […]

A SURVEY OF BUTTERFLY FAUNA IN THE SACRED GROVE OF UMUAJA FOREST, SOUTHERN NIGERIA

Abstract Sacred groves in Africa have been widely adopted as an important strategy to assuage the loss of biodiversity. This has led to the protection of sacred groves (which are virgin forest with rich diversity) for their cultural, religious beliefs and taboos. This study represents the first butterfly survey of the Umuaja sacred grove and […]

STATUS AND TRENDS OF EUCALYPTUS EXPANSION AND ITS ENVIRONMENTAL IMPLICATION IN MEKET DISTRICT, NORTH WELLO ZONE, ETHIOPIA

Abstract Eucalyptus is one of the exotic and multipurpose tree grown in Ethiopia. This paper aims to assess the spatiotemporal expansion of eucalyptus trees in Meket district, north-central Ethiopia. Multistage sampling techniques reaching from farmer’s perception to remote sensing data processing were employed. Household heads survey of 192 farmers, key informant interviews, and focus group […]

ECOLOGICAL ASSESSMENT OF ITAPAJI RESERVOIR STATUS IN ITAPAJI USING PLANKTON ASSEMBLAGE

Abstract Itapaji Reservoir in Ekiti State serves for municipal water supply, artisanal fishing, agricultural and domestic uses, and recently earmarked for irrigation of the adjoining land.  There is paucity of information on the limnology of the reservoir, hence this study to provide relevant information on its trophic status for effective water management. Plankton samples (120) […]

ASSESSMENT OF THE IMPACT OF INTRODUCTION OF CULTURE BASED FISHERIES ON FISH PRODUCTION IN WATER BODIES OF ETHIOPIA

Abstract In Ethiopia, the implementation of comprehensive water resources development program, particularly irrigation and hydro power generation could be additional opportunity to increase farm productivity through integration of culture based fishery and water resources uses. The role of fishery and aquaculture in reducing poverty and alleviating food insecurity at household level is enormous. The main […]

COMPARISON OF MACROPHYTES DISTRIBUTION IN LAKE HAWASSA AT DIFFERENT POLLUTION ENTRY POINTS, HAWASSA, ETHIOPIA

Abstract Lake Hawassa is currently impinged by the various human activities in its watershed. This could create favourable conditions for the invasive macrophytes like water hyacinth attacking Lake Tana and Koka. Hence, identification of the impacts of pollution on the macrophytes species diversity, distribution and coverage is very important. In doing so, rapid bioassessment method […]
