The phenomenon of musth in male elephants involves increased sexual activity, heightened aggression and nearly continuous dribbling of pungent smelling urine. Urine chemistry during musth is altered, suggesting that urine may signal the musth status

Serum corticosterone was previously studied in numerous elasmobranch fishes (sharks, skates and rays), but the role of this steroid, widespread throughout many taxa, has yet to be defined. The goal of this study was to test whether corticosterone var

Using automated solid-phase dynamic extraction and gas chromatography-mass spectrometry, our search for urinary chemical signals from ovulatory female African elephants (Loxodonta africana) has revealed the bark beetle aggregation pheromones frontali

African elephants are a polygynous species that raise offspring in a matriarchal society. Unlike females, males disperse, spend time in male groups and search for mates when mature. Urinary chemical signals aid males in detecting reproductively activ

We acquired magnetic resonance images of the brain of an adult African elephant, Loxodonta africana, in the axial and parasagittal planes and produced anatomically labeled images. We quantified the volume of the whole brain (3,886.7 cm3) and of the n

Recently, our group performed the first histologic, histochemical, and immunohistochemical analysis of eccrine-type interdigital glands in the Asian elephant (Elephas maximus) (Lamps et al. [2001] Res Vet Sci 71:197–200). Since morphologically simi

Musth is an important male phenomenon affecting many aspects of elephant society including reproduction. During musth, the temporal gland secretions (as well as the urine and breath) of adult male Asian elephants (Elephas maximus) discharge a variety

In many mammals, reproductive status is revealed through chemical cues in urine. The reproductive status of receivers may influence their interest in such signals. For social mammals that live in matrilineal groups, females may benefit by detecting t

The mating season of the Atlantic stingray (Dasyatis sabina), which begins in August and continues through April, is the longest documented for any elasmobranch fish. Despite this protracted mating period, female stingrays ovulate synchronously at th
