Pacific tree frogs Hyla regilla are typically either green or brown in dorsal coloration. The frequency of green and brown individuals is known to fluctuate seasonally. Previous investigators have generally assumed that the green and brown body colors represent a “fixed” polymorphism and that seasonal changes in the proportion of the two body colors are a consequence of differential survival of the two color morphs. Here we report that, in addition to the “fixed” (i.e., non‐color‐changing… Expand
Background matching by means of dorsal color change in treefrog populations (Hyla japonica).

TLDR
Testing predictions of the physiological model for color change in treefrogs by investigating dorsal color change under five background colors in three different populations of the treefrog Hyla japonica suggested that chroma change capacity may be sensitive to environmental conditions. Expand
The control of color change in the Pacific tree frog, Hyla regilla
TLDR
A within-subject, full factorial experiment designed to determine the simple and interactive effects of background, temperature, and light intensity on the rate of color change in the Pacific tree frog found increased rates of hue, chroma, lightness, and color change with increasing initial hue, Chroma,Lightness,and color distances. Expand
Consistent Frequency of Color Morphs in the Sea Star Pisaster ochraceus (Echinodermata:Asteriidae) across Open-Coast Habitats in the Northeastern Pacific1
TLDR
It is found that the frequency of orange sea stars in a population increases with the size of the animals in most populations, and the most parsimonious explanation is that adult color is a selectively neutral genetic trait that expresses itself ontogenetically. Expand
Microhabitat selection by the Pacific treefrog, Hyla regilla
TLDR
Background colour choice in the Pacific treefrog, Hyla regilla, a species that shows a complex colour polymorphism is investigated but there is no evidence for differences in spectral sensitivity curves among the three morphs that would suggest a visual pigment polymorphism in the retina. Expand
Cryptic Behavior Is Independent of Dorsal Color Polymorphism in Juvenile Northern Leopard Frogs (Rana pipiens)
TLDR
This study suggests that juvenile Northern Leopard Frogs exhibit a generalized cryptic behavior pattern independent of background body color, which may result in differential substrate preference among color morphs. Expand
Colour and pattern change against visually heterogeneous backgrounds in the tree frog Hyla japonica
TLDR
This work investigated the colour change process of the Japanese tree frog against patterned backgrounds and elucidated how the expression of dorsal patterns changes against various achromatic/chromatic backgrounds with/without patterns and found substantial individual variation in colour changing ability and the levels of dorsal pattern expression between individuals. Expand
Benthic fish exhibit more plastic crypsis than non-benthic species in a freshwater spring
TLDR
A subtle, rapid, and reversible crypsis in which small fish exhibit muted changes in brightness to match varying substrates in clear spring water is examined, suggesting that rapid crypticChanges in brightness may augment other forms of defense in small vulnerable fish. Expand
Background matching ability and the maintenance of a colour polymorphism in the red devil cichlid
TLDR
Testing the ability of differently coloured individuals to phenotypically adjust the shade of their body colour and patterns to match their background found that gold individuals appeared to be more conspicuous, suggesting that a difference in background matching ability could play an important role in the maintenance of colour polymorphisms. Expand
Lizard colour plasticity tracks background seasonal changes
TLDR
The findings show that lizards are capable of altering dorsal coloration during seasonal change, and closely followed environmental background colour variation and enhanced lizard crypsis during each season. Expand
Background colour matching in a wild population of Alytes obstetricans
TLDR
A positive correlation between coloration of toads and background colour for the three components of the colour is found, suggesting that common midwife toads might adjust skin coloration to match the surrounding environment, thus benefitting from short-term reversible crypsis strategies against predators.

The colors and color adaptation of the European tree frog, Hyla arborea, have been investigated by means of reflectance microspectrophotometry. The results are compared to those previously publishedExpand
Physiological Color Change in the Green Treefrog: Responses to Background Brightness and Temperature
TLDR
The results suggest that color change may function both in predator avoidance and in thermoregulation or water balance, and further investigations of color change responses to differently hued backgrounds, of the magnitude and biological significance of color-induced changes in body temperature and rates of evaporative water loss, and ofcolor change in freeranging animals are needed.

The Significance of Color Change in Newly Metamorphosed American Toads (Bufo a. americanus)
TLDR
Both dark- and light-matched toads preferred the dark background, and toads moved less frequently on the dark Background, and Toads showed no tendency to change color as a function of desiccation or temperature. Expand
ESTIMATION OF RELATIVE VIABILITY AND FECUNDITY OF COLOR POLYMORPHISMS IN ANURANS
TLDR
This study was initiated in an attempt to obtain estimates of the differential viability observed during the various seasons and to examine critically whether or not changes in frequencies of the several color types could be observed between years. Expand
Microhabitat selection and predation in the Pacific Treefrog, Pseudacris regilla
TLDR
The results suggest that genetically-determined phenotypic variants can reduce the risk of predation through microhabitat selection, and indicate that visual predators can be important selective agents in the evolution and maintenance of color polymorphisms. Expand

Distribution of and reproductive isolation among color morphs of a rock‐dwelling Lake Victoria cichlid (Haplochromis nyererei)
TLDR
The data support the hypothesis that polymorphisms can be a step preceding speciation in cichlid fish and suggest the status of color morphs as phenotypes of one species or as separate biological species is a function of environmental conditions that vary considerably between the localities. Expand
Plumage Reflectance and the Objective Assessment of Avian Sexual Dichromatism
TLDR
This study revealed previously unnoticed sex differences in plumage coloration and the nature of iridescent and noniridescent sex differences, which has important implications for classifications of animals as mono‐ or dimorphic and for taxonomic and conservation purposes. Expand
The Evolution of Threshold Traits in Animals
  • D. Roff
  • Biology
  • The Quarterly Review of Biology
  • 1996
TLDR
The threshold model of quantitative genetics, in which discrete morphs are determined by some underlying continuously distributed trait and a threshold(s) of expression, is applied appropriately in these cases, shows that no morph has a universally higher fitness, but that there is a tradeoff, with the relative fitnesses of two morphs being contingent upon environmental conditions.

Physiological color change in the bullfrog, Rana catesbeiana.
TLDR
These results, taken together with the lack of lightening activity of norepinephrine on alpha-MSH-darkened skins, suggest that R. catesbeiana melanophores do not possess very active beta-adrenoceptors and lack alpha-adreneceptors, and that the chromatic rhythm is not endogenous, and most likely is determined by the light/dark cycle effect onalpha- MSH secretion.
