Large-scale coal mining practices, particularly surface coal extraction and associated valley fills as well as residential wastewater discharge, are of ecological concern for aquatic systems in central Appalachia. Identifying and quantifying alterations to ecosystems along a gradient of spatial scales is a necessary first-step to aid in mitigation of negative consequences to aquatic biota. In central Appalachian... Read more.

Mangrove stands in the Western and Central African countries especially that of Cameroon are declining due to diverse drivers. Actually, Rhizophora racemosa stands in the Cameroon Estuary have been degraded through over-exploitation for fish smoking, pole-wood extraction and fuel wood harvesting by local people in the midst where there is no specific law protecting this ecosystem. Recently, community-based mangrove... Read more.

Anthropogenic activities have the potential to thwart efforts towards enhancing the full carbon (C) sink potential of savannas in the context of mitigating the effects of global warming. The understanding of the induced effects of human pressures on the carbon budget of forest˗savanna ecosystems is therefore a valuable tool to better evaluate and predict the current and future effects of human activities on the...

Increasing effects of climate change has led to an urgent need for reliable estimates of the soil carbon pool (SOC) which is one of the carbon sinks in the world. This is especially true in Africa where there is lack of basic data. This study conducted in the southern part of Mount Cameroon National Park (MCNP) seeks to determine SOC patterns and estimate CO2 equivalence from SOC pool following land-use changes. Nine...

A total of ten soil samples were collected from four different dump sites in Port Harcourt Metropolis. The samples were examined for temperature, pH, total heterotrophic bacterial and fungal counts. The mean temperature values of the soils ranged from 27 to 28°C while the mean pH values ranged from 6.5 to 7.8. The total heterotrophic bacterial population ranged from 2.4 × 107 to 1.2 × 108 cfu/g while... Read more.
