“…Chiu and Maderson, 1975;Cole, 1966;Regamey, 1935;Van Wyk, 1990). Manipulative experiments showed that castration of males or supplementation of estrogen caused atrophy of femoral glands (Fergusson et al, 1985;Forbes, 1941). This atrophy can be later reversed with T supplementation.…”

“…This atrophy can be later reversed with T supplementation. Moreover, female lizards, which usually do not have femoral glands or that have femoral pores but without secretory activity, can develop femoral glands and start to form femoral secretions after supplementation of androgens (Chiu et al, 1970;Fergusson et al, 1985). Both male and female juvenile striped plateau lizards, Sceloporus virgatus, increased their femoral pore secretions when theywere given testosterone-filled implants (Abell, 1998).…”

This article is part of a Special Issue "Chemosignals and Reproduction". Many lizards have diverse glands that produce chemosignals used in intraspecific communication and that can have reproductive consequences. For example, information in chemosignals of male lizards can be used in intrasexual competition to identify and assess the fighting potential or dominance status of rival males either indirectly through territorial scent-marks or during agonistic encounters. Moreover, females of several lizard species "prefer" to establish or spend more time on areas scent-marked by males with compounds signaling a better health or body condition or a higher genetic compatibility, which can have consequences for their mating success and inter-sexual selection processes. We review here recent studies that suggest that the information content of chemosignals of lizards may be reliable because several physiological and endocrine processes would regulate the proportions of chemical compounds available for gland secretions. Because chemosignals are produced by the organism or come from the diet, they should reflect physiological changes, such as different hormonal levels (e.g. testosterone or corticosterone) or different health states (e.g. parasitic infections, immune response), and reflect the quality of the diet of an individual. More importantly, some compounds that may function as chemosignals also have other important functions in the organism (e.g. as antioxidants or regulating the immune system), so there could be trade-offs between allocating these compounds to attending physiological needs or to produce costly sexual "chemical ornaments". All these factors may contribute to maintain chemosignals as condition-dependent sexual signals, which can inform conspecifics on the characteristics and state of the sender and allow making behavioral decisions with reproductive consequences. To understand the evolution of chemical secretions of lizards as sexual signals and their relevance in reproduction, future studies should examine what information the signals are carrying, the physiological processes that can maintain the reliability of the message and how diverse behavioral responses to chemosignals may influence reproductive success.

“…In several species of lizards, including the eublepharids E. macularius and C. elegans, T-treatment also stimulates the production of pore secretions in adult females (Chiu et al, 1975;Crews et al, 1998;Fergusson et al, 1985;Hews and Moore, 1995). However, pore secretions were absent in both control and T-treated females of G. lichtenfelderi.…”

“…Previous studies have established that the production of secretions from the precloacal pores is significantly influenced by circulating levels of androgens in male lizards (Chiu et al, 1975;Crews et al, 1998;Fergusson et al, 1985;Hews and Moore, 1995;Lindzey and Crews, 1993;Rhen et al, 2005). In several species of lizards, including the eublepharids E. macularius and C. elegans, T-treatment also stimulates the production of pore secretions in adult females (Chiu et al, 1975;Crews et al, 1998;Fergusson et al, 1985;Hews and Moore, 1995).…”

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 (molecular, biochemical, behavioral) and is related to sensory processing and the physiological effects of pheromone delivery. These and related studies show that natural pheromones can be identified, validated with behavioral tests, and incorporated in research on vomeronasal functional response.
