“…Sceloporus graciosus lizards replenish chemical secretions weekly (Martins et al 2006), suggesting that these signals may persist for even longer time periods. Here, we found profound changes in space use by S. undulatus males presented with chemical cues near the same site in which Hews et al (2011) found no effect of chemical cues on behavior during the 5-min field trials. Collectively, these results emphasize that even when attraction to chemical signals is not detected in immediate behavioral measures, it can manifest gradually over time and in more subtle ways.…”

“…This site has been used for other previous studies on chemical behavior in lizards (Hews et al 2011). S. undulatus lizards form clumped spatial distributions, and most lizard activity takes place in and near rocky outcrops (Jones & Droge, 1980) between Apr.…”

“…As Sceloporus lizards are primarily sit-and-wait predators that do not actively forage, much of their movement patterns can be attributed to thermoregulatory and territorial behavior. During the breeding season, males boost production of chemical signals (femoral gland secretions; FGSs) that are secreted from specialized glands through pores on the inner thighs, which elicit aggressive territorial responses in conspecifics (Duvall 1979; Hews et al 2011) and are used to scent-mark territories (Mayerl et al 2015). S. undulatus exhibit site fidelity across years (Ferner 1974), associate with specific landmarks, and favor particular perching structures (Jones & Droge, 1980).…”

In Space and Time: Territorial Animals are Attracted to Conspecific Chemical Cues

Territorial animals lay scent marks around their territories to broadcast their presence, but these olfactory signals can both attract and repel con-specifics. Attraction or aversion can have a profound impact in terms of space use and thereby influence an individual’s access to resources and mates. Here, we test the impact of chemical signals on the long-term space use and activity of receivers, comparing the response of males and females, territory holders, and temporary visitors in Sceloporus undulatus lizards in the field. We placed either male femoral gland secretions (chemical) or blank (control) cues on resident male landmarks, repeatedly over 5 d, while monitoring the activity and location of all lizards in the vicinity. We found that resident males and females, but not non-resident males, were active on more days near landmarks treated with chemical cues than landmarks treated with control cues. Non-resident males remained closer to chemical than control cues. These results suggest that territorial scent marks are attractive to conspecifics and impact space use, but that the specific effects depend on receiver sex and residency status. Such subtle or gradual changes in behavior may frequently be overlooked by short-term choice experiments. Future studies investigating the behavioral significance of a communicative signal should consider these finer details of behavior for a more comprehensive assessment.

“…Across Sceloporus lizards, there is evidence of evolutionary tradeoffs between headbob display duration and complexity (Martins, 1993) and between visual and chemical markers of territory boundaries (Ossip-Klein, Fuentes, Hews, & Martins, 2013). Whereas loss of an aggressive colour signal in males of one species of Sceloporus lizards was accompanied by a compensatory increase in chemical behaviour (Hews & Benard, 2001; Hews, Date, Hara, & Castellano, 2011), there was no evidence of a compensatory shift in chemical cues for male crickets that have lost an acoustic signal (Gray, Bailey, Poon, & Zuk, 2014). …”

Evolving from static to dynamic signals: evolutionary compensation between two communicative signals

Signals that convey related information may impose selection on each other, creating evolutionary links between different components of the communicative repertoire. Here, we ask about the consequences of the evolutionary loss of one signal (a colour patch) on another (a motion display) in Sceloporus lizards. We present data on male lizards of four species: two pairs of sister taxa representing two independent evolutionary losses of the static colour patch (Sceloporus cozumelae and Sceloporus parvus; Sceloporus siniferus and Sceloporus merriami). Males of the two species that have undergone an evolutionary loss of blue-belly patches (S. cozumelae, S. siniferus) were less active than their blue-bellied sister taxa (S. parvus, S. merriami), consistent with the suggestion that the belly patches were lost to reduce conspicuousness of species with high predation pressure. In contrast, the headbob display appears to have become more, rather than less, conspicuous over evolutionary time. The colour patch is exhibited primarily during aggressive encounters, whereas headbob displays are multifunction signals used in several different contexts, including aggressive encounters. Males of species that have lost the colour patch produced more motion displays, and the structure of those motion displays were more similar to those produced during combat. In both evolutionary episodes, a static colour signal appears to have been replaced by dynamic motion displays that can be turned off in the presence of predators and other unwanted receivers. The predominant pattern is one of evolutionary compensation and interactions between multiple signals that convey related information.

“…Studies have also demonstrated that chemical or pheromonal cues play an important role in social interactions of several species of reptiles, including the eublepharid gecko E. macularius, such as for the identification of conspecifics and distinguishing between the sexes (Brillet, 1993;Cooper and Steele, 1997;Greenberg, 1943;Mason and Gutzke, 1990;Shine et al, 2002;reviewed in Houck, 2009;Martin and Lopez, 2011; but see Hews et al, 2011). Furthermore, studies suggest that these chemical cues used for sex recognition may be altered by manipulation of sex steroid levels (Flores and Crews, 1995;.…”
