Coevolution in Action: Disruptive Selection on Egg Colour in an Avian Brood Parasite and Its Host
BACKGROUND Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection. METHODOLOGY/PRINCIPAL FINDING Here, we show through detailed field studies and experimental procedures that the ashy-throated parrotb...
متن کاملPaternity-parasitism trade-offs: a model and test of host-parasite cooperation in an avian conspecific brood parasite.
Efforts to evaluate the evolutionary and ecological dynamics of conspecific brood parasitism in birds and other animals have focused on the fitness costs of parasitism to hosts and fitness benefits to parasites. However, it has been speculated recently that, in species with biparental care, host males might cooperate with parasitic females by allowing access to the host nest in exchange for cop...
متن کاملSocial learning of a brood parasite by its host.
Arms races between brood parasites and their hosts provide model systems for studying the evolutionary repercussions of species interactions. However, how naive hosts identify brood parasites as enemies remains poorly understood, despite its ecological and evolutionary significance. Here, we investigate whether young, cuckoo-naive superb fairy-wrens, Malurus cyaneus, can learn to recognize cuck...
متن کاملExperimental evidence for chick discrimination without recognition in a brood parasite host.
Recognition is considered a critical basis for discriminatory behaviours in animals. Theoretically, recognition and discrimination of parasitic chicks are not predicted to evolve in hosts of brood parasitic birds that evict nest-mates. Yet, an earlier study showed that host reed warblers (Acrocephalus scirpaceus) of an evicting parasite, the common cuckoo (Cuculus canorus), can avoid the costs ...
متن کاملIdentification by circumstantial evidence
The assumedly mortal remains of Queen Editha (Eadgyth) (91o–946 AD), wife of Otto the Great (912–973 AD) were subject of identification. The aim of the multi disciplinary investigations of an international research team was to test the hypothesis that the coffin indeed contained the skeletal remains of Queen Editha, as an inscription on its lid states. Biographical data of the historic Editha h...
