FLORISTICS AND STRUCTURE OF FALLOW VEGETATION
Vegetation-environment (soil) was studied in fallow plots in Uyo, ranging from 0-year-old to 6-year-old. Systematicsampling method was used to sample both vegetation and soil. The parameters determined for vegetation included; Height,Frequency, Basal area and Crown cover for all species. The soil physical and chemical properties were also determined.Results obtained showed that there were eight (8) plant species in the 0-year old plot, 12 species in the 2-year old plot,20 species of plants in...
Influence of Seasonality Gradients on Phytodiversity Richness in Rural and Urban Wetlands
The composition and distribution of flora species in wetlands are dependent upon several environmental variables and one of such is seasonality regimes. Seasonal gradients exert profound influence on seedling establishment, regeneration and reproduction of plant species. To this end, rural and urban wetlands were studied to assess the influence of seasonality gradients on phytodiversity richness. A ten 5m×5m quadrat was used to sample the vegetation for density of species with spacing at r...
Morpho-Physiological Responses and Arbuscular Mycorrhizal Amelioration of Telfairia Occidentalis Hook F. to Combinational Stress
Crops are faced with several definite environmental stresses either concurrently or at different periods during their entire growth and productivity season. Combinational occurrence of stresses and pollution such as salinity stress and crude oil pollution is destructive to crop growth and productivity than these stresses occurring separately at different crop growth. This research was aimed at showing different stress combinations (salinity stress and crude oil pollution) and their impact on ...
Comparative Studies on the Pedological Characteristics, Morphological Traits and Productivity Indices of Three Species of the Genus Ipomoea in Uyo Metropolis, Akwa Ibom State, Nigeria
Comparative studies on the pedological characteristics, morphological traits and productivity indices of three species of the genus Ipomoea was done in Uyo metropolis, Akwa Ibom State, Nigeria. Morphological parameters (leaf length, leaf width and leaf area index) and productivity indices (chlorophyll a, b carotenoids and Chlorophyll Concentration Index (CCI)) of these species were determined using standard methods. The results showed that amongst the three species studied Ipomoea mauritiana ...
MACROPHYTE ABUNDANCE AND WATER QUALITY STATUS OF THREE IMPACTED INLET STREAMS ALONG IKPA RIVER BASIN, AKWA IBOM STATE, NIGERIA
Assessment of macrophyte abundance and water quality of three impacted inlet streams along Ikpa River Basin were investigated. A 5m x 5m quadrat through systematic sampling was used to sample the vegetation for density and frequency of species. Sediment and water samples were collected and analyzed using standard methods. From the results obtained, a total of 23 macrophyte species from 17 families were encountered. Stream 1 (Ntak Inyang 1) had 7 species, stream 2 (Ntak Inyang 2) had 13 specie...
Geochemical Assessment of Heavy Metal Contamination in rural and urban wetlands in Akwa Ibom State, Nigeria
Nutrient and waste inputs into wetlands have dire consequences on both soil and water quality and by extension dependent aquatic flora and fauna. Within this purview, heavy metal contamination was assessed in a rural and urban wetland in Akwa Ibom State, Nigeria. Soil samples were analyzed for Pb, Zn, Fe, Ni and Cd using AAS. Results show marked variations of heavy metal concentrations within study area. Mean values of Fe (713.22 ± 59.39), Pb (5.95 ± 0.42), Zn (88.54 ± 8.03) and Cd (1.53 �...
Influence of Pedological Regimes on Plants Distribution in a Lacustrine Wetland in Uyo, Akwa Ibom State, Nigeria.
Studies on the influence of pedological regimes on plant distribution in a lacustrine wetland in Uyo, Akwa Ibom State, Nigeria revealed variations in density and frequency of plant species as a function of the soil parameters. A quadrat size of 5m x 5m through systematic sampling was used to sample the vegetation spaced at regular intervals. The vegetation parameters determined were density and frequency. Soil samples were collected at different depths (0 – 15 cm and 15 – 30 cm) and ana...
