Pheromonal regulation of reproductive success in female zebrafish: female suppression and male enhancement
Competition among females represents an important but rather neglected variable in studies of sexual selection. Probably to avoid injury to self and offspring, competition among females is often displayed without much physical interaction and therefore remains harder to observe. Here, we show for the first time in a teleost fish, the zebrafish Danio rerio, that […]
Conspecific trailing behaviour of red-sided garter snakes, Thamnophis sirtalis parietalis, in the natural environment
The ability of animals to orient based on pheromonal cues in the environment can have significant consequences to their reproductive success and survival. For example, it is hypothesized that snakes use pheromone trails to locate potential mates during the breeding season and to locate winter hibernacula. Numerous studies have demonstrated that snakes are capable of […]
