Article
In our study, we explore how the phenotypes (morphology and behaviour) of endemic bird species that live on islands evolve over time. There are two main ideas about these phenotypic changes: one idea is that birds evolve to fill specific roles i[...]

Jocelyn Champagnon, Auteur ; Johan Elmberg, Auteur ; Matthieu Guillemain, Auteur ; Philip Lavretsky, Auteur ; Robert G. Clark, Auteur ; Par Soderquist, AuteurIn the Anthropocene, human activities have been a dominant force affecting wildlife, natural habitats, and climate worldwide. Over time, increasing incidences of wildlife-human interactions may have positive outcomes for some generalist species,[...]

Patrick-Jean Guay, Auteur ; Lucinda Monie, Auteur ; Randall W. Robinson, Auteur ; Wouter F. D. van Dongen, AuteurInterspecific hybridisation is common amongst birds and is associated with diverse costs and benefits. Several mechanisms are thought to promote hybridisation, including heterospecific mate choice, species recognition errors and interspecific fo[...]
