Assessment of landscape-scale distribution of sympatric great apes in African rainforests: concurrent use of nest and camera-trap surveys.

Information on the distribution and abundance of sympatric great apes (Pan troglodytes troglodytes and Gorilla gorilla gorilla) are important for effective conservation and management. Although much research has been done to improve the precision of nest-surveys, trade-offs between data-reliability and research-efficiency have not been solved. In this study, we used different approaches to assess the landscape-scale distribution patterns of great apes.

In vitro antiplasmodial and antibacterial activities of Canthium multiflorum Schum and Thonn (Rubiacea) extracts.

Because of the resistance of pathogens to actually available drugs, there is a continuous need for new agents to cure several diseases such as malaria and microbial infections. In the establishment of new drugs, plant are often a source of new leads, indeed aqueous, acetone and methanol extracts of Canthium multiflorum were tested for antiplasmodial and antibacterial activities. The antiplasmodial activity was performed on fresh clinical strains of Plasmodium falciparum using light microscopy.
