Sexual dimorphism in the performance of chemosensory investigatory behaviours by African elephants (Loxodonta africana)

Sexual dimorphism in morphology can be accompanied by behavioural differences between the sexes. We examined if investigatory behaviour involving the trunk of African elephants showed sexual dimorphism. Males compete and search for females, but they have a lengthy period of development before they are socially viable mates. Receptive females are relatively rare. We hypothesized that […]

Eliciting play: A comparative study

The social play behavior of six mammalian species (Rodentia, Pinnipedia, Artiodactyla, Carnivora) is described and compared. Locomotor and Rotational Movements, e.g., jumping, running, and headshaking, occurred in all species and predominated in the rodent play. These movements are similar in form to anti-predator and “protective” responses and result in an immediate but temporary cessation of […]
