Are cuckoos maximizing egg mimicry by selecting host individuals with better matching egg phenotypes?
Antonov, Anton Tinchov; Stokke, Bård Gunnar; Fossøy, Frode; Ranke, Peter Sjolte; Liang, Wei; Yang, Canchao; Moksnes, Arne; Shykoff, Jacqui A.; Røskaft, Eivin (Journal article; Peer reviewed, 2012)Background: Avian brood parasites and their hosts are involved in complex offence-defense coevolutionary arms races. The most common pair of reciprocal adaptations in these systems is egg discrimination by hosts and egg ... -
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 ... -
Diversity of parasitic cuckoos and their hosts in China
Yang, Canchao; Liang, Wei; Antonov, Anton Tinchov; Cai, Yan; Stokke, Bård Gunnar; Fossøy, Frode; Moksnes, Arne; Røskaft, Eivin (Journal article, 2012)In this exposé we provide the first review of host use by brood parasitic cuckoos in a multiple-cuckoo system in China, based on our own long-term field data and a compilation of observations obtained from the literature. ... -
Egg phenotype matching by cuckoos in relation to discrimination by hosts and climatic conditions
Avilés, Jesús M.; Vikan, Johan Reinert; Fossøy, Frode; Antonov, Anton Tinchov; Moksnes, Arne; Røskaft, Eivin; Shykoff, Jacqui A.; Møller, Anders pape; Stokke, Bård Gunnar (Journal article, 2012)Although parasites and their hosts often coexist in a set of environmentally differentiated populations connected by gene flow, few empirical studies have considered a role of environmental variation in shaping correlations ... -
Host selection in parasitic birds: are open-cup nesting insectivorous passerines always suitable cuckoo hosts?
Yang, Canchao; Stokke, Bård Gunnar; Antonov, Anton Tinchov; Cai, Yan; Shi, Suhua; Moksnes, Arne; Røskaft, Eivin; Møller, Anders pape; Liang, Wei; Grim, Tomas (Journal article; Peer reviewed, 2013)How do potential hosts escape detrimental interactions with brood parasites? Current consensus is that hole-nesting and granivorous birds avoid brood parasites, like common cuckoos Cuculus canorus , by their inaccessible ... -
Increase of clutch size triggers clutch destruction behaviour in common moorhens (Gallinula chloropus) during the incubation period
Wang, Longwu; Yang, Canchao; Hsu, Yu-Cheng; Antonov, Anton Tinchov; Moksnes, Arne; Røskaft, Eivin; Liang, Wei; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2013)Conspecific brood parasitism (CBP) is common in a variety of animal taxa, including birds. In coots (Fulica spp.), and the closely related moorhens (Gallinula spp.), such parasitism is especially common, and hosts experience ... -
Large hawk-cuckoo Hierococcyx sparveroides parasitism on the Chinese babax Babax lanceolatus may be an evolutionary recent host-parasite system
Yang, Canchao; Antonov, Anton Tinchov; Cai, Yan; Stokke, Bård Gunnar; Moksnes, Arne; Røskaft, Eivin; Liang, Wei (Journal article; Peer reviewed, 2012)We documented brood parasitism by the poorly studied Large Hawk-Cuckoo on a previously unknown host species, the Chinese Babax. Furthermore, we describe a new egg colour for the Large Hawk-Cuckoo. The parasitism rate of ... -
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 Allocation in Relation to Host Races in the Brood-Parasitic Common Cuckoo (Cuculus canorus)
Fossøy, Frode; Moksnes, Arne; Røskaft, Eivin; Antonov, Anton Tinchov; Dyrcz, Andrzej; Moskát, Csaba; Ranke, Peter Sjolte; Rutila, Jarkko; Vikan, Johan Reinert; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2012)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 ... -
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 ... -
UV reflectance as a cue in egg discrimination in two Prinia species exploited differently by brood parasites in Taiwan
Yang, Canchao; Wang, Longwu; Hsu, Yu-Cheng; Antonov, Anton Tinchov; Moksnes, Arne; Røskaft, Eivin; Liang, Wei; Stokke, Bård Gunnar (Journal article, 2013)Birds are capable of seeing the ultraviolet light (UV) spectrum and as a consequence have evolved UV-reflective structures with signalling functions. Avian eggs also reflect in the UV spectrum but the importance of UV egg ... -
Why do brood parasitic birds lay strong-shelled eggs?
Antonov, Anton Tinchov; Stokke, Bård Gunnar; Fossøy, Frode; Liang, Wei; Moksnes, Arne; Røskaft, Eivin; Yang, Canchao; Møller, Anders Pape (Journal article, 2012)Brood parasitic birds constitute a model system for the study of coevolution. Such parasites are unique by having evolved unusually thick eggshells for their body size. Thick eggshells have been hypothesized to evolve as ...
