“…Nonmelanic populations from large areas with variable elevation‐associated environmental conditions (Figure b) show similar light dorsal color, while the melanic population in HSK exhibits dark dorsal color in high altitude as well (Figure a), indicating that elevation is probably not contributing to explain the variance of coloration. Moreover, substrate color difference has been previously found to explain coloration variation within a species between geographically nearby populations, for example, Anolis carolinensis (Macedonia, Echternacht, & Walguarnery, ), Crotalus lepidus lepidus (Farallo & Forstner, ), and Montivipera raddei species complex (Rajabizadeh et al, ). We propose that this is the same case for melanic HSK and nonmelanic GZ populations.…”

“…Many reptiles will match their body coloration to habitat environments, including turtles (Hall, Robson, & Ariel, 2018;McGauch, 2008;Rowe, Bunce, & Clark, 2014;Rowe, Miller, et al, 2014;Xiao et al, 2016), snakes (Rajabizadeh, Adriaens, Kaboli, Sarafraz, & Ahmadi, 2015), gecko (Vroonen, Vervust, Fulgione, Maselli, & Damme, 2012), and lizards (Corl et al, 2018;Hamilton et al, 2008;Krohn & Rosenblum, 2016;Stuart-Fox, Moussalli, & Whiting, 2008;Tao et al, 2018). These animals can adapt to varied substrate coloration in physiological and/or morphological color change.…”

Diversity in animal coloration is generally associated with adaptation to their living habitats, ranging from territorial display and sexual selection to predation or predation avoidance, and thermoregulation. However, the mechanism underlying color variation in toad‐headed Phrynocephalus lizards remains poorly understood. In this study, we investigated the population color variation of Phrynocephalus versicolor. We found that lizards distributed in dark substrate have darker dorsal coloration (melanic lizards) than populations living in light substrates. This characteristic may improve their camouflage effectiveness. A reciprocal substrate translocation experiment was conducted to clarify the potential role of morphological adaptation and physiological plasticity of this variation. Spectrometry technology and digital photography were used to quantify the color variation of the above‐mentioned melanic and nonmelanic P. versicolor populations and their native substrate. Additionally, substrate color preference in both populations was investigated with choice experiments. Our results indicate that the melanic and nonmelanic populations with remarkable habitat color difference were significantly different on measured reflectance, luminance, and RGB values. Twenty‐four hours, 30 days, and 60 days of substrate translocation treatment had little effects on dorsal color change. We also found that melanic lizards choose to live in dark substrate, while nonmelanic lizards have no preference for substrate color. In conclusion, our results support that the dorsal coloration of P. versicolor, associated with substrate color, is likely a morphological adaptation rather than phenotypic plasticity.

“…Increasingly, multiple selective factors are recognized as jointly contributing to the evolution of morphology (e.g. predators and solar radiation on Cepaea nemoralis land snails [4,5]; thermoregulation and crypsis in Montivipera raddei mountain vipers [6]; thermoregulation and aposematic warning signals in Parasemia plantaginis wood tiger moths [7]).…”

Trade-offs direct the evolution of coloration in Galápagos land snails

et al. 2019

Increasingly, multiple selective factors are recognized as jointly contributing to the evolution of morphology. What is not clear is how these forces vary across communities to promote morphological diversification among related species. In this study of Galápagos endemic snails (genus Naesiotus), we test several hypotheses of colour evolution. We observe mockingbirds (genus Mimus) predating live snails and find that avian predation selects against conspicuous shells. The evolutionary outcome of this selection is a diversity of shell colours across snails of the archipelago, each closely matching local backgrounds. We also find that snails more regularly exposed to the hot, equatorial sun reflect more light than shells of species from shadier habitats, suggesting a role for thermoregulatory constraints directing colour evolution. The signature of thermoregulatory selection is most clear in comparatively young communities (on the youngest islands), while the signature of selection from predators is most evident in older communities (on the older islands). Together, our findings point to a scenario of shifting selective forces along island ontogeny and community maturity that lead to the distribution of snail coloration we observe in Galápagos. Complex selective regimes such as these may have more responsibility for morphological diversity than is currently recognized.

To what extent different components of a colour pattern contribute to the protective value of an aposematic signal remains largely unclear.…”
