Lures and other adaptations for prey attraction are particularly interesting from an
evolutionary viewpoint because they are characterized by correlational selection, involve …

The study of deceptive signalling has provided compelling insights into evolutionary and
ecological processes. Aside from mimicry, however, research into the use of colour as a …

Background Modern molecular analyses are often inconsistent with pre-cladistic taxonomic
hypotheses, frequently indicating higher richness than morphological taxonomy estimates …

Camouflage is used by prey to avoid detection by predators, and by predators to remain
unseen by their prey. Effective camouflage can be achieved through background matching …

Receiver biases offer opportunities for the evolution of deception in signalling systems.
Many spiders use conspicuous body colouration to lure prey, yet the perceptual basis of …

Selection for signal efficacy in variable environments may favor color polymorphism, but little
is known about this possibility outside of sexual systems. Here we used the color …

One of the most evident sources of phenotypic diversity within a population is colouration, as
exemplified by colour polymorphism. This is relevant to a greater extent in animals with …

Animal body colours can be shaped by many factors, including the need to attract mates,
avoid predators and lure prey. In some contexts, these needs might compete. A number of …

Animal body coloration serves several functions such as thermoregulation, camouflage,
aposematism, and intraspecific communication. In some orb-web spiders, bright and …

Spiders that build aerial webs in open areas face the risk of overheating due to incident
solar radiation. These spiders can counteract overheating by either moving the web to …
