      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 ...
    • 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 ...
    • Deficiency in egg rejection in a host species as a response to the absence of brood parasitism 

      Yang, Canchao; Wang, Longwu; Cheng, Shun-Jen; Hsu, Yu-Cheng; Stokke, Bård Gunnar; Røskaft, Eivin; Moksnes, Arne; Liang, Wei; Møller, Anders Pape (Journal article, 2015)

    • 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 ...

      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. ...
    • Geographic variation in egg ejection rate by great tits across 2 continents 

      Liang, Wei; Møller, Anders Pape; Stokke, Bård Gunnar; Yang, Canchao; Kovařík, Petr; Wang, Haitao; Yao, Cheng-Te; Ding, Ping; Lu, Xin; Moksnes, Arne; Røskaft, Eivin; Grim, Tomas (Journal article; Peer reviewed, 2016)
      Hosts of brood parasites may vary geographically in their ability to resist parasitism. In contrast, geographic variation in defenses, such as egg rejection, is not expected to be present or vary geographically in unsuitable ...
    • 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 ...
    • Plaintive cuckoos do not select tailorbird hosts that match the phenotypes of their own eggs 

      Yang, Canchao; Huang, Qiuli; Wang, Longwu; Jiang, Aiwu; Stokke, Bård Gunnar; Fossøy, Frode; Tunheim, Odd Helge; Røskaft, Eivin; Liang, Wei; Møller, Anders Pape (Journal article; Peer reviewed, 2016)
      Laying a mimetic egg is important for a brood parasite to succeed in defeating the defenses of a host that can recognize and reject nonmimetic foreign eggs. Several recent studies suggest that common cuckoos ( Cuculus ...
    • Reject the odd egg: Egg recognition mechanisms in parrotbills 

      Yang, Canchao; Møller, Anders Pape; Røskaft, Eivin; Moksnes, Arne; Liang, Wei; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2014)

      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 ...

      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 ...
