Red coloration and the evolution of aposematism in arboreal sciurids
<p>An animal's coloration is associated with a variety of processes and is therefore subjected to multiple selective pressures. Mammals, especially, are typically inconspicuously colored, or cryptic, to avoid detection by predators. Alternatively, an animal may use conspicuous coloration to advertise the presence of an anti-predator defense. The association between signal and defense is called aposematism. Conspicuous black and white coloration has recently been associated with a range of defenses in mammals, including body size (Howell et al. 2021), however red coloration as a potentially aposematic signal has yet to be investigated in mammals. Squirrels, like most mammals, are unable to perceive red for use as a social signal. Here we use a comparative framework to test whether redness could be a means of background matching, serve a thermoregulatory function or be an honest warning of anti-predator defenses across a global distribution of tree squirrels which vary in size from 16g to 2.2kg in this study. We measured redness of the dorsum, the venter and of red accents of study skin specimens of 57 tree squirrel species (N=257) representing 25 genera. We then associated these phenotypic variables with environmental variables using phylogenetic generalized least squares regression. We find that increasing dorsal redness is associated with more humid environments and closed canopies, consistent with prior work that coloration on this body region under selection for crypsis (Sheets and Chavez 2020). However, we find that ventral redness and maximum redness is associated with large body sizes. Our findings suggest that crypsis and aposematism are not mutually exclusive, and that aposematism may be more widespread in mammals than is currently appreciated.<u></u></p>
