Sex-limited polymorphism has evolved in many species including our own. Yet, we lack a
detailed understanding of the underlying genetic variation and evolutionary processes at …

Sexual conflict over mating rate is widely regarded as a selective force on the evolution of
female-limited color polymorphism in invertebrates, such as damselflies and butterflies …

Female-only colour polymorphism is rare in birds, but occurs in brood parasitic cuckoos
(Cuculidae). Obligate brood parasites leave incubation and parental care to other species …

Sexual dimorphism is ubiquitous in animals and can result from selection pressure on one
or both sexes. Sexual selection has become the predominant explanation for the evolution …

In coevolutionary arms races, interacting species impose selection on each other,
generating reciprocal adaptations and counter adaptations. This process is typically …

Background Plumage polymorphism may evolve during coevolution between brood
parasites and their hosts if rare morph (s), by contravening host search image, evade host …

The common cuckoo (Cuculus canorus) is an obligate brood parasite that mimics the eggs
of its hosts. The host-specific egg pattern is thought to be inherited matrilinearly, creating …

Although egg color polymorphism has evolved as an effective defensive adaptation to brood
parasitism, spatial variations in egg color polymorphism remain poorly characterized. Here …

Generalist parasites regularly evolve host-specific races that each specialize on one
particular host species. Many host-specific races originate from geographically structured …

Recent evidence suggests that blue-green coloration of bird eggshells may be related to
female and/or egg phenotypic quality, and that such colour may affect parental effort and …
