Sexual reproduction and the exchange of genetic information are essential biological
processes for species across all branches of the tree of life. Over the last four decades …

This selective review considers herpetological papers that feature the use of chemical cues,
particularly pheromones involved in reproductive interactions between potential mates …

Intraspecific communication involves the activation of chemoreceptors and subsequent
activation of different central areas that coordinate the responses of the entire organism …

Pheromonal communication is widespread in salamanders and newts and may also be
important in some frogs and toads. Several amphibian pheromones have been behaviorally …

Pheromonal communication is an ancient and pervasive sensory modality in urodelan
amphibians. One family of salamander pheromones (the sodefrin precursor-like factor (SPF) …

Vertebrate pheromones that affect female receptivity have been documented only in
salamanders. These courtship pheromones have been investigated most intensively in …

This article is part of a Special Issue “Chemosignals and Reproduction”. Amphibians are
often thought of as relatively simple animals especially when compared to mammals. Yet the …

The amygdala of all tetrapod vertebrates receives direct projections from the main and
accessory olfactory bulbs, and the strong similarities in the organization of these projections …

Plethodontid salamanders display intricate courtship behaviors. Proteinaceous courtship
pheromones were recently discovered in the submandibular (mental) gland of the male …

Pheromones are important chemical signals for many vertebrates, particularly during
