Antipredator defenses and warning signals typically evolve in concert. [...] Key Result Using a mouse-based toxicity assay, we find extreme variation in toxicity between frog populations. This variation is significantly positively correlated with frog coloration brightness, a viewer-independent measure of visual conspicuousness (i.e., total reflectance flux). We also examine conspicuousness from the view of three potential predator taxa, as well as conspecific frogs, using taxon-specific visual detection models…Expand
Differential responses of avian and mammalian predators to phenotypic variation in Australian Brood Frogs
TLDR
This study shows a differential predator response to ventral coloration in this genus which has implications for the evolution of conspicuous signaling in Pseudophryne. Expand
An Analysis of Predator Selection to Affect Aposematic Coloration in a Poison Frog Species
TLDR
It is concluded that conspicuousness honestly indicates toxicity to avian predators and the different coloration patterns among populations of strawberry poison frogs in combination with behavior and toxicity might integrate into equally efficient anti-predator strategies depending on local predation and other ecological factors. Expand
Intrasexual selection and warning color evolution in an aposematic poison dart frog
TLDR
It is demonstrated through spectrophotometry and visual modeling that aposematic brightness variation within this population is likely visible to two putative predators and conspecifics, but not to the presumed major predator (birds). Expand
The interplay between multiple predators and prey colour divergence
TLDR
Evidence is provided for the interplay among distinct selective pressures, from multiple-predator taxa, acting on the divergence in protective coloration of prey species in populations where relatively cryptic green morphs have evolved. Expand
Conspicuous displays in cryptic males of a polytypic poison-dart frog
TLDR
It is found that, despite being less visible under some measures, green frogs may appear as bright as red frogs for conspecifics but not birds, when viewed on dark backgrounds, suggesting that green frogs retain context-dependent conspicuousness to conspecials despite the evolution of relative crypsis to potential predators. Expand
Diversity in warning coloration is easily recognized by avian predators
TLDR
While ladybird signals are unique and recognizable, specialist species are more contrasting against the background they are most commonly found on than compared to average ones, suggesting that warning signals have evolved to be effective against a wide range of natural backgrounds. Expand
Warning signal properties covary with toxicity but not testosterone or aggregate carotenoids in a poison frog
TLDR
It is found that although measures of male brightness do not correlate with two classic correlates of sexually selected traits, male reflectance does show a positive correlation with concentrations of two xanthophyll carotenoids and total reflectance also shows a negative relationship with aggregate pumiliotoxin in the skin. Expand
Warning Signal Brightness Variation: Sexual Selection May Work under the Radar of Natural Selection in Populations of a Polytypic Poison Frog
TLDR
This study suggests that signal brightness within D. pumilio populations can be shaped by sexual selection, with limited opportunity for natural selection to influence this trait due to predator sensory constraints. Expand
Courting danger: socially dominant fish adjust their escape behavior and compensate for increased conspicuousness to avian predators
Males of many species display conspicuous colors to attract mates and deter rivals, although this benefit can incur an increased predation risk. In the African cichlid fish, Astatotilapia burtoni,Expand
Body size but not warning signal luminance influences predation risk in recently metamorphosed poison frogs
TLDR
Artificial models of postmetamorphic froglets that varied in terms of body size and signal luminance indicate that body size was a significant predictor of artificial prey survival and suggests that smaller froglets may be at a selective disadvantage at the completion of metamorphosis. Expand

Interspecific and intraspecific views of color signals in the strawberry poison frog Dendrobates pumilio
TLDR
The results indicate that the colors displayed by the various color morphs of D. pumilio are effective signals both to conspecifics and to a model predator. Expand
The role of predator selection on polymorphic aposematic poison frogs
TLDR
A purifying role for predator selection is demonstrated, as brightly coloured novel forms are more likely to suffer an attack than both local aposematic and cryptic forms, and colour patterns of poison frogs may truly represent a ‘magic trait’. Expand
A mechanism for diversity in warning signals: conspicuousness versus toxicity in poison frogs.
TLDR
It is demonstrated that closely related species use alternative strategies: increasing either conspicuousness or toxicity affords equivalent avoidance by predators and provides protection to nontoxic mimic species, providing a mechanism for natural diversity in warning signals. Expand

TLDR
This study suggests that specific components of the aposematic signal are affected differently by natural and sexual selection, and female tolerance of unfamiliar coloration patterns could facilitate the establishment of novel phenotypes that are favored by other selective pressures. Expand
Visual ecology of the fiddler crab, Uca tangeri: effects of sex, viewer and background on conspicuousness
TLDR
One of the most conspicuous features of both male and female crabs is an area that is likely to be more visible to crabs (mouthparts) than to avian predators from above, suggesting that males may increase the conspicuousness of their signals by modifying their signalling environment. Expand
APOSEMATIC SIGNAL VARIATION PREDICTS MALE–MALE INTERACTIONS IN A POLYMORPHIC POISON FROG
TLDR
The first examination of how aposematic signal variation influences male–male interactions in a highly territorial poison frog species reveals two behavioral patterns, which indicate the potential for sexual selection by male– male competition to impact aposemat signal evolution. Expand

TLDR
Comparative analysis of the evolutionary relationships among representative species of poison frogs indicated a significant correlation between the evolution of toxicity and coloration across this family, consistent with the hypothesis that coloration in this group is aposematic. Expand

TLDR
It is shown that optimal aposematic conspicuousness can be positively correlated with optimal prey toxicity, especially where population sizes and season lengths vary between species, and when displays incur no allocation costs. Expand
