Intrasexual selection and warning color evolution in an aposematic poison dart frog
Flamboyant colors are widespread throughout the animal kingdom. While many of these traits arise through sexual selection, bright coloration can also evolve through natural selection. Many aposematic species, for example, use conspicuous warning coloration to communicate their noxiousness to …

Evolution of colour vision in relation to colouration in weaverbirds (Family Ploceidae) and poison dart frogs (Family Dendrobatidae)
… weaverbirds (Family Ploceidae) and poison dart frogs (Family Dendrobatidae). In both systems, colouration is used to assess sexual rivals and/or potential mates, making assessing colouration or distinguishing between colours a crucial ability. Both systems also feature multiple colour …
