• 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)
      Studies of the behavior of animals when confronted with tasks differing in complexity can improve our understanding of animal cognition and learning mechanisms. Coevolutionary interactions between brood parasites and their ...
    • Reviewing 30 years of studies on the Common Cuckoo - accumulated knowledge and future perspectives 

      Moksnes, Arne; Fossøy, Frode; Røskaft, Eivin; Stokke, Bård Gunnar (Journal article, 2013)
      In Europe, eggs of the Common Cuckoo (Cuculus canorus) have been found in more than 125 different host species. However, very few species are frequently parasitized. The Cuckoo is divided into several distinct races termed ...
    • 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 ...
    • The Role of Wildlife Education in Conservation Biology: Can awareness change Locals` Attitudes towards the Endangered African Wild Dog (Lycaon pictus) ? 

      Straube, Anne Cathrine Strande (Master thesis, 2013)
      In this master thesis, I will concentrate on the increasing interest for the research field of conservation biology, and what it can do to contribute to turn the future development in a more sustainable direction for a ...
    • 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 ...
