Abstract 10.1002/zoo.1430110605.abs Mandrills, Mandrillus sphinx, colorful terrestrial primates from the tropical forests of West Central Africa, are poorly known in the wild. The formation at the International Medical Research Center of Franceville, Gabon, of a semifreeranging, cohesive, reproducing group of mandrills in a highly naturalistic setting provided a unique resource for the study of this […]
Assessment of landscape-scale distribution of sympatric great apes in African rainforests: Concurrent use of nest and camera-trap surveys

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 […]
