| Abstract | We examined sex differences in copulation attempts in a group of wild bonobos at Wamba, Congo, by analyzing the behavioral sequence. Most copulation attempts were initiated by approach or courtship behaviors by males. Males showed these behaviors when they were more than 5 m from females, whereas females did so only when males solicited them from within 5 m. Most copulations involved females showing perineal swelling, because males solicited those females more frequently and those females accepted copulation more frequently than did females in the non-swelling phase. Nevertheless, males solicited females in the non-swelling phase in one-third of copulation attempts, and those females accepted copulation in half of those attempts. This is markedly different from chimpanzees, in which sexual behaviors almost exclusively involve females in the swelling phase. The perineum of female bonobos during the non-swelling phase is soft and wrinkled but fairly large, which may attract males to some extent. The low, but existing, attractiveness and receptivity of female bonobos during the non-swelling phase might have evolved to control sexual competition among males and provide higher social status for females. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
