Source and cyclic release pattern of (Z)-7-dodecenyl acetate, the pre-ovulatory pheromone of the female Asian elephant.

Female Asian elephants (Elephas maximus) release a pre-ovulatory urinary pheromone, (Z)-7-dodecenyl acetate (Z7--12:Ac), to signal males of their readiness to mate, as demonstrated by two complementary headspace techniques.

Evolution of Pheromones in Mammals

A review is devoted to the analysis of the role of pheromones in the organization of mammalian behavior in the evolutionary aspect and the future perspectives of research in this area are discussed.

Androgen plays an important role in regulating the synthesis of pheromone in the scent gland of muskrat

A pheromone bouquet controls the reproductive behaviour of the male shore crab, Carcinus maenas

High Performance Liquid Chromatography analysis of female urine shows that the pheromone, identified as the nucleotide uridine diphosphate (UDP), elutes as an unresolved peak with structurally related nucleotides, providing evidence that a phersomone bouquet composition is not always constant.

The Case of Atypical Sexual Attractiveness in a Male Domestic Dog—A Case Study

The case of strong, but atypical attractiveness of a castrated male to various, adult, intact males, influenced by the emitted semiochemical signals is described, the first described case presenting this phenomenon, which could shed new light on the process of creation of sexual attraction in the domestic dog.



Asian bull elephants: Flehmen-like responses to extractable components in female elephant estrous urine.

Components of the urine of estrous cow elephants were extracted with organic solvents and partially purified by chromatography and shown to evoke Flehmen-like responses when they were presented to adult bulls.

Reproductive cycle of the Asian elephant (Elephas maximus) in captivity.

Serum concentrations of P4 fell dramatically before parturition, consistent with a role for this steroid in the regulation of gestational length and the first substantive description of the hormonal milieu of the reproductive cycle, concurrent male behavior, and the serum hormonal patterns at the onset and termination of gestation in this endangered species.
