This selective review considers herpetological papers that feature the use of chemical cues, particularly pheromones involved in reproductive interactions between potential mates. Primary examples include garter snake females that attract males, lacertid lizards and the effects of their femoral gland secretions, aquatic male newts that chemically attract females, and terrestrial salamander males that chemically persuade a female to mate. Each case study spans a number of research approaches… 
Social behavior and pheromonal communication in reptiles
TLDR
The role of pheromones in orchestrating social behaviors in reptiles is reviewed and Reptiles provide excellent candidates for further studies in this regard not only in squamates, but also in the orders where little experimental work has been conducted to date.
Investigating pheromone variability in a terrestrial woodland salamander
TLDR
Some aspects of pheromone variability will be explored in two Plethodontid salamanders using biochemical methods and the phenomenon of female mate-choice as a behavioral measure.

TLDR
Study of additional species of amphibians will indicate which traits related to pheromonal communication are evolutionarily conserved and which traits have diverged over time.
Conspecific chemical cues facilitate mate trailing by invasive Argentine black and white tegus
TLDR
It is demonstrated for the first time that females of an invasive reptile species can follow conspecific scent trails, and sex-specific targeting of tegus via application of a conspecial chemical cue in traps could enhance removal rates of females during the breeding season.
Condition-dependent chemosignals in reproductive behavior of lizards
Taxonomic patterns of tadpole behavioural responses to alarm cues
TLDR
It is shown that avoidance is the most commonly observed type of response to alarm cues, and that response behaviors depend on the origin of the alarm cue, and on whether the tadpoles belong to a species with a gregarious or solitary life style.
Chemical cues and pheromones in the sea lamprey (Petromyzon marinus)
TLDR
It is suggested that the sea lamprey is a broadly useful organism with which to study vertebrate olfaction because of its simple but well-developed olfactory organ, the dominant role of olf action in guiding behaviors during reproduction, and the direct implications for vertebrate pest management.
Chemical communication for reproduction in the Tasmanian short-beaked echidna, Tachyglossus aculeatussetosus
TLDR
The results suggest that females do not ‘actively’ signal to males while hibernating, but intense male-male competition for access to females has probably driven earlier male readiness to breed, even before females might otherwise emerge from hibernation and signal toMale echidnas.
Volatile compound secretion coincides with modifications of the olfactory organ in mantellid frogs
TLDR
Experimental evidence suggests that the pheromone of one mantelline, Mantidactylus betsileanus, distinctly stimulates sensory neurons in the MOO but not in the VNO, supporting an evolutionary connection of derived olfactory anatomy with chemical communication in these frogs.

TLDR
The ability to correlate physiological measures with estimates of reproductive success identifies areas of amphibian research that will profit from continued attention from a combination of evolutionary and mechanistic perspectives.

TLDR
Investigations of the species-specific nature of these pheromones indicate that chemical differences exist in the methyl ketones of all species examined to date.
Pheromonal activation of vomeronasal neurons in plethodontid salamanders
TLDR
It is suggested that a specific population of vomeronasal neurons in a female plethodontid salamander is responsible for transmitting pheromonal information to the brain to produce modifications in behavior.
Amphibian Pheromones and Endocrine Control of Their Secretion
TLDR
An increase in the level of both immunoassayable pheromones caused by treatment with these hormones has also been demonstrated, and the responsiveness of the female vomeronasal epithelial cells to sodefrin is enhanced markedly by a combination of prolactin and estrogen.
Proteinaceous pheromone affecting female receptivity in a terrestrial salamander.
TLDR
A 22-kilodalton protein was isolated from the submandibular (mental) gland of the male terrestrial salamander, Plethodon jordani, and experimentally delivered to the female during courtship and shown to increase female receptivity.
Chemical Analysis of Courtship Pheromones in a Plethodontid Salamander
TLDR
The chemical nature of Pj-22 fits the profile for odorants that stimulate the vomeronasal organ and can ultimately affect reproductive behavior and is considered in the context of separate behavioral experiments with P. jordani that indicated delivery of pooled gland extracts resulted in increased female receptivity and an enriched solution of PJ-22 also was effective at increasingFemale receptivity.
A recombinant courtship pheromone affects sexual receptivity in a plethodontid salamander.
TLDR
The recombinant PRF (rPRF) is one of only 2 synthesized vertebrate proteins to retain full biological activity and appears to mimic the activity of a mixture of PRF isoforms, as well as a combination of multiple different proteins that comprise the male courtship gland extract.

TLDR
The recent characterization of genes encoding molecular components of the VNO sensory response suggests that VNO neurons express a unique set of molecules to recognize and translate pheromone signals into neuronal electrical activity.
Evolution and comparative genomics of odorant- and pheromone-associated genes in rodents.
TLDR
The consequences of selection on rodent pheromones, their receptors, and olfactory receptors are estimated and it is predicted that these contribute to physicochemical and functional diversity within phersomone-receptor interaction sites.
Conspecific and heterospecific pheromone effects on female receptivity
TLDR
The results suggest that the courtship pheromone signal and function may be conserved across related species, with mate discrimination occurring before phersomone delivery.
