Even as numerous studies have documented that the red and yellow coloration resulting
from the deposition of carotenoids serves as an honest signal of condition, the evolution of …

Urbanisation can affect mating opportunities and thereby alter inter‐and intra‐sexual
selection pressures on sexual traits. Biotic and abiotic urban conditions can influence an …

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors.
These conspicuous colors serve a diversity of signaling functions, but their molecular basis …

Thirty years of research has made carotenoid coloration a textbook example of an honest
signal of individual quality, but tests of this idea are surprisingly inconsistent. Here, to …

The concept of stress is notoriously difficult to define, despite its ubiquity in both common
parlance and the scientific literature. Given the clear importance of understanding how …

The study of coloration in the polyphyletic reptilians has flourished in the last two decades, in
particular with respect to the underlying genetics of colour traits, the function of colours in …

Animal colors play important roles in communication, ecological interactions and speciation.
Carotenoid pigments are responsible for many yellow, orange and red hues in animals …

Colour polymorphic species are model systems for examining the evolutionary processes
that generate and maintain discrete phenotypic variation in natural populations. Lizards …

Animals display incredibly diverse color patterns yet little is known about the underlying
genetic basis of these phenotypes. However, emerging results are resha** our view of …

Space is a limited resource in which many animals need to perform basic functions such as
feeding and reproducing. Competition over access to space can induce a variety of …
