Ancient origin and maternal inheritance of blue cuckoo eggs
Røskaft, Eivin; Møller, Anders P.; Liang, Wei; Sorenson, Michael D; Yang, Canchao; Takasu, Fugo; Stokke, Bård Gunnar; Fossøy, Frode; Moksnes, Arne; Ekrem, Torbjørn; Rutila, Jarkko (Journal article; Peer reviewed, 2016)Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or ‘gentes’) in avian brood parasites. Here we report ... -
Coevolution in Action: Disruptive Selection on Egg Colour in an Avian Brood Parasite and its Host
Yang, Chanchao; Liang, Wei; Cai, Yan; Shi, Suhua; Takasu, Fugo; Møller, Anders pape; Antonov, Anton Tinchov; Fossøy, Frode; Moksnes, Arne; Røskaft, Eivin; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2010)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 ... -
Disappearance of eggs from non-parasitized nests of brood parasite hosts – the evolutionary equilibrium hypothesis revisited
Stokke, Bård Gunnar; Røskaft, Eivin; Moksnes, Arne; Møller, Anders Pape; Antonov, Anton Tinchov; Fossøy, Frode; Liang, Wei; Lopez-Iborra, German; Moskát, Csaba; Shykoff, Jacqui A.; Soler, Manuel; Vikan, Johan Reinert; Yang, Canchao; Takasu, Fugo (Journal article; Peer reviewed, 2016)The evolutionary equilibrium hypothesis was proposed to explain variation in egg rejection rates among individual hosts (intra- and interspecific) of avian brood parasites. Hosts may sometimes mistakenly reject own eggs ... -
Egg arrangement in avian clutches covaries with the rejection of foreign eggs
Polacikova, Lenka; Takasu, Fugo; Stokke, Bård Gunnar; Moksnes, Arne; Røskaft, Eivin; Cassey, Phillip; Hauber, Mark; Grim, Tomas (Journal article, 2013)In birds, the colour, maculation, shape, and size of their eggs play critical roles in discrimination of foreign eggs in the clutch. So far, however, no study has examined the role of egg arrangement within a clutch on ... -
Modelling the maintenance of egg polymorphism in avian brood parasites and their hosts
Liang, Wei; Yang, Canchao; Stokke, Bård Gunnar; Antonov, Anton Tinchov; Fossøy, Frode; Vikan, Johan Reinert; Moksnes, Arne; Røskaft, Eivin; Shykoff, Jacqui A.; Møller, Anders Pape; Takasu, Fugo (Journal article, 2012)In avian brood parasitism, egg phenotype plays a key role for both host and parasite reproduction. Several parrotbill species of the genus Paradoxornis are parasitized by the common cuckoo Cuculus canorus, and clear ... -
Sex roles in egg recognition and egg polymorphism in avian brood parasitism
Liang, Wei; Yang, Canchao; Antonov, Anton Tinchov; Fossøy, Frode; Stokke, Bård Gunnar; Moksnes, Arne; Røskaft, Eivin; Shykoff, Jacqui A.; Møller, Anders Pape; Takasu, Fugo (Journal article, 2012)Avian brood parasites impose strong selection on their hosts leading to the evolution of antiparasite defenses like egg recognition and rejection. Discordance and template-based cognitive mechanisms may form the base for ...
