Dung counts have been widely used to estimate duiker abundance and densities in tropical African forests. However, one of the major limitations of this method is that species’ identification of dung based on morphological characteristics is extremely difficult in most cases. Some authors made the...

We analysed seasonality of dung decay time and the influence of rainfall, leaf fall, beetle attack and moisture on dung decay. Our study was carried out at the Ipassa Reserve, north-east Gabon. We compared the seasonality of dung decay with the seasonality of dung beetle abundance and guild struc...

This study determined the structure of cocoa plantations along a continuous gradient of market access, population density and resource use intensity in the humid forest zone of southern Cameroon. The study area comprises the sub-regions of Yaoundé, Mbalmayo, and Ebolowa. Market access, population...

Estimating the potential land resources suitable for irrigation and evaluating the possible impact of climate change on land suitability is essential for planning a sustainable agricultural system. This study applied a GIS-based Multi-Criteria Evaluation (MCE) technique to evaluate the suitabilit...

The Multipurpose Tree (MPT) species can fit into the farming systems of the East African region where low agricultural productivity, widespread land degradation and hence a diminishing capacity to support the growing human and livestock population are major problems. GIS has been used to develop ...

Through reconciling census totals with population structure, annual survival rates were estimated for the juvenile, yearling and adult stages of 10 ungulate species over 14 years or longer in South Africa's Kruger National Park. During this period four species maintained high abundance levels, wh...
