    • 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 ...

    • 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 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 ...

    • 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 ...
