Chemosensory Behavior and Development of African Male Elephants (Loxodonta Africana)
African elephants are a polygynous species that raise offspring in a matriarchal society. Males disperse, spend time in male groups, and search for mates when mature. Urinary chemical signals play an important role in detecting reproductively active females. African male elephants develop movement, …

Patterns of Chemosensory Behavior in a Closed Population of Wild African Elephants (Loxodonta Africana)
… identity, status, or location of conspecifics. Elephants are a long-lived species and males reproduce at a much later age than females, which provides a protracted developmental period for males. This study examined chemosensory behaviors in a population of African elephants living in Addo …

In this study of African elephants (Loxodonta africana), I examined two competing hypotheses to explain the development of social and reproductive behaviors. The reproductive hypothesis states that behaviors change around the time when an individual begins successfully reproducing, while the social …
