The experiment was conducted to assess land degradation in agrarian soils of Ebonyin State. Ten farmers’ fields were selected based on land use and landscape positions across the three zones in the state. Physical and socio- economic information were obtained from the farmers and extension agents. Surface and sub-surface soil samples were collected for physical and chemical analysis. The soils at the upland were... Read more.

In the Kafue floodplains, Zambia, a study was done to determine whether meristic and/or other morphological metrics could distinguish putative hybrids (based on color patterns) between non-indigenous Oreochromis niloticus (Nile tilapia) and two native species of Oreochromis andersonii (three spot tilapia) and Oreochromis macrochir (green head tilapia) from the pure parental strains. We also surveyed local fishermen to... Read more.

Hagenia-shaped habitat is an important element in conservation of world’s only population of mountain gorillas surviving in the wild. In fact, in the Parc National des Volcans (henceforth PNV), gorillas spend most of their life time in the nutritious herbaceous habitats near or within the Hagenia-Hypericum zone. Unfortunately, populations of Hagenia abyssinica in this park have been reported to be ageing. Using... Read more.

Macroinvertebrates formed an important constituent of an aquatic ecosystem and had functional importance in assessing the trophic status as the abundance of benthic fauna mainly depends on physical and chemical properties of the substratum and thus the benthic communities respond to changes in the quality of water and available habitat. This review discussed the occurrence, compo-sition and distribution of... Read more.

Arbuscular mycorrhizal fungi (AMF) play a key role in land reclamation, sustaining soil fertility and cycling of nutrients, which in turn increases plant vigour and productivity. AMF differ in both structural characteristics and global distribution, which is strongly correlated with the respective functional role. This study investigated the molecular diversity of arbuscular mycorrhizal fungi (AMF) in selected... Read more.
