“…In closely related species, the total number of blue spots is positively correlated with body size and condition (López et al 2004;Cabido et al 2009) and the relative proportion of some chemical compounds of femoral secretion (López et al 2006). In addition, López et al (2004) found that the presence, but not the number, of blue spots may elicit aggressiveness in Iberolacerta monticola.…”

A bright ultraviolet (UV) component in the coloration of males may signal individual quality and thus determine the outcome of male-male contests. Yet, the role of the UV component of coloration in resolving conflicts is still controversial relative to factors such as residency status and seasonality. Here, we investigated whether a reduction of UV reflectance of lateral blue spots in male wall lizards (Podarcis muralis) interacts with residency status (resident vs. intruder) to influence agonistic behaviors, the outcome of contests, and basking time (a measure of spatial dominance). We performed this experiment during one breeding and one non-breeding season. The UV manipulation did not predict the outcome of contests. During the breeding season, the agonistic behaviors and basking time depended on the residency status of males but not on their UV treatment. During the non-breeding season, experimental factors affected basking time only. For a given male, the time spent basking depended in a complex manner on its residency status, its UV treatment, and those of its rival. UV reflectance of blue spots thus influences the processes of mutual assessment and spatial dominance, but is not a critical determinant of fighting success. Altogether, these results evidence context-dependent effects of the UV reflectance of blue spots on territorial behaviors according to residency status and, potentially, season. They also suggest that UV signaling may be more important than expected for malemale interactions during the non-breeding season.

“…Past researchers have suggested a genetic correlation between melanin‐based pigmentation, stress resistance, and the boldness of parents when defending nests against predators (Quesada and Senar , Ducrest et al , Boerner and Krüger , van den Brink et al ). Further, in non‐parental contexts, researchers have found that individuals with more intense carotenoid‐based pigmentation are bolder under predation risk (Godin and Dugatkin ), perhaps because they better evade predation (Cabido et al ). However, conspicuous coloration might also increase the risk of detection by predators, and thus induce stronger responses to predation threats, especially where vegetative cover is limited.…”

“…For instance, under low levels of predation risk, highly ornamented individuals might display better parental performance than others, as predicted by ‘good parent’ models of sexual selection (Hoelzer , Hill , Siefferman and Hill ). In contrast, under high predation risk, highly ornamented individuals might abandon parental effort if vulnerable to detection or capture by predators (Martin and Badyaev , Götmark and Olsson , Cabido et al ). Alternatively, highly ornamented individuals might be more willing to maintain parental effort under predation risk if better able to evade predators (Fowler‐Finn and Hebets ), if ornamentation indicates higher investment towards current reproduction rather than survival (Candolin ), or if ornamentation correlates with behavioral characteristics such as boldness and aggressiveness (Roulin , Ducrest et al , Da Silva et al ).…”

Sexual pigmentation and parental risk‐taking in yellow warblers Setophaga petechia

Adult‐directed predation risk imposes important behavioral constraints on parents and might thus alter relationships between costly sexual ornaments and parental performance. For instance, under low predation risk, highly ornamented individuals might display better parental performance than others, as predicted by ‘good parent’ models of sexual selection. However, under high risk of predation, highly ornamented individuals might abandon parental effort if conspicuous to predators, or if social partners are more willing to take parental risks when paired with highly ornamented mates. We experimentally elevated perceived adult‐directed predation risk near nests to explore how carotenoid‐ and phaeomelanin‐based pigmentation in both sexes relate to parental risk‐taking for offspring in the yellow warbler Setophaga petechia. Compared to other males, males with more intense carotenoid‐based pigmentation maintained higher levels of paternal effort under predation risk at highly concealed nests, but reduced nestling provisioning rate more at exposed nests. Further, when faced with predation risk, females with more phaeomelanin‐based pigmentation reduced nestling provisioning rate less than other females, regardless of nest concealment. Females displayed higher parental effort across treatments when paired to males with more colorful carotenoid pigmentation. However, birds did not reduce parental effort under risk less when paired to a highly ornamented mate, suggesting that predation risk did not accentuate differential allocation. Males did not take fewer parental risks than females. Results indicate that nest concealment modifies parental risk‐taking by males with colorful carotenoid‐based pigmentation, and suggest that female melanin‐based pigmentation may indicate boldness and greater a propensity to take parental risks.

“…For example, relative conspicuity to predators of different individuals may affect the risk of being detected and this should affect escape decisions. Some studies showed that visual conspicuousness of coloration correlates positively with shyness (Forsman & Appelqvist, 1998;Martín & López, 1999a;Cuadrado et al, 2001;Lindström et al, 2007;Cabido et al, 2009;Møller et al, 2011; but see Godin & Dugatkin, 1996); and in some lizards, FID vary among species, being inversely correlated with the degree of cryptic coloration (Heatwole, 1968;Johnson, 1970), or within a species as a function of the degree of conspicuousness in different microhabitats (Cooper, 1998a;Cuadrado et al, 2001). Also, in several cases, there are differences between the escape tactics of males and females.…”

Antipredator escape behaviour shows great variation with well-established sources of variation being the physical environment and the ecological context. However, the relative roles of these sources are rarely assessed together. We measured the distance that Schreiber's green lizards, Lacerta schreiberi allowed a simulated predator to approach before fleeing (flight initiation distance; FID) to know which are the main determinants of escape decisions. The environment had direct effects on the lizards' escape strategy; FID showed strong positive relationship with distance to refuge on grassy, but not on rocky substrates. Furthermore, refuge distance and the escape angle had a complex, substrateindependent, interaction effect: either short refuge distances or large escape angles resulted in short FIDs. In contrast, neither season (reproductive vs. nonreproductive), nor sex affected FID. We suggest that the escape strategy of this lizard is determined mainly by the environmental settings, irrespective of the ecological context or sexual roles.
