Stable Oxygen and Carbon Isotopic Compositions of Lates stappersii Otoliths from Lake Tanganyika, East Africa
Aboubakar Sako, Kenneth G. MacLeod, and Catherine M. O’Reilly
In this study, we measured growth trends in oxygen and carbon isotopic ratios in whole sagittal otoliths from three adult centropomid fish (Lates stappersii) from each of three sub-basins of Lake Tanganyika, East Africa. Sampling density was 20 to 50 samples per otolith. Both d 18C values increase with age. The d 18O and d 13O data suggest tha(...)

This Augsut 2000-September 2002 study monitored crop damage by elephants in the vicinity of Kakum CA. The Conservation Area, comprised of about 370 sq kms formerly known as Kakum NP and Attandanso FR, has a population of about 220 elephant. The forest in the protected area is a fragment of the lowland forest the once occupied much of southwest(...)

Variations in otolith elemental compositions of two clupeid species, Stolothrissa tanganicae and Limnothrissa miodon in Lake Tanganyika
Aboubakar Sako, Catherine M. O’Reilly, Ronald L. Johnson, Robyn Hannigan &Nate Bickford
Lake Tanganyika in East Africa has two primary basins (Northern and Southern) and borders four sovereign countries. Effective management of the fisheries of this lake requires sound biological understanding of the various fish stocks. The feasibility of fish stock identification within different basins and sub-basins of this lake was attempted thr(...)

The Kakum Conservation Area appears to be Ghana's most successful national park, what with 60,000 visitors each year and its role in boosting the economy of Cape Coast, the regional capital.But to the local farming community, the park is not such a blessing.Marauding elephants damage their crops, making the local community hostile towards the(...)

Results from a dry season dung count carried out during January 2001 in Ankasa Conservation Area estimate a population of approximately 21 elephant. Most of the animals were found in the vicinity of the Suhien River. A pre-study reconnaissance had statified the areas into three stata, low, medium and high, based on assumed density. However, th(...)
