Rapid change in host use of the common cuckoo Cuculus canorus linked to climate change.
Parasites require synchrony with their hosts so if host timing changes with climate change, some parasites may decline and eventually go extinct. Residents and short-distance migrant hosts of the brood parasitic common cuckoo, Cuculus canorus, have advanced their phenology in response to climate change more than long-distance migrants, including the cuckoo itself. Because different parts of Eur...
متن کاملEvolution of host egg mimicry in a brood parasite, the great spotted cuckoo
Brood parasitism in birds is one of the best examples of coevolutionary interactions in vertebrates. Coevolution between hosts and parasites is assumed to occur because the parasite imposes strong selection pressures on its hosts, reducing their fitness and thereby favouring counter-adaptations (e.g. egg rejection) which, in turn, select for parasite resistance (e.g. egg mimicry). Great spotted...
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 کاملCoevolution 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 کاملSex Allocation in Relation to Host Races in the Brood-Parasitic Common Cuckoo (Cuculus canorus)
Sex allocation theory and empirical evidence both suggest that natural selection should favour maternal control of offspring sex ratio in relation to their ability to invest in the offspring. Generalist parasites constitute a particularly interesting group to test this theory as different females commonly utilize different host species showing large variation in provisioning ability. The common...
