Article
Speciation—the multiplication of species through the evolution of barriers to reproduction between populations—plays a central role in evolution since it enables two or more populations to adapt and evolve independently. However, mechanisms of s[...]

Scott A. Taylor, Auteur ; David J. Anderson, Auteur ; Carlos B. Zavalaga, Auteur ; Vicki L. Friesen, AuteurHybrid zones represent natural laboratories in which the processes of divergence and genetic isolation can be examined. The generation and maintenance of a hybrid zone requires mispairing and successful reproduction between organisms that differ[...]
Article
Scott A. Taylor, Auteur ; James A. Morris-Pocock, Auteur ; Zhengxin Sun, Auteur ; Vicki L. Friesen, AuteurTen microsatellite loci were isolated and characterized from Blue-footed (Sula nebouxii) and Peruvian Boobies (S. variegata). The loci were screened in 24 Blue-footed Boobies and 27 Peruvian Boobies: 8 were polymorphic in Blue-footed Boobies wit[...]

Mark Bolton, Auteur ; Andrea L. Smith, Auteur ; Elena Gomez-Diaz, Auteur ; Vicki L. Friesen, Auteur ; Renata Medeiros, Auteur ; Joël Bried, Auteur ; Jose L. Roscales, Auteur ; Robert W. Furness, AuteurThe existence of two seasonally distinct breeding populations of Oceanodroma storm-petrels in the Azores islands was first documented in 1996. The discovery of morphological differences between the populations led to the suggestion that they may[...]

Scott A. Taylor, Auteur ; Carlos B. Zavalaga, Auteur ; Guillermo Luna-Jorquera, Auteur ; Alejandro Simeone, Auteur ; David J. Anderson, Auteur ; Vicki L. Friesen, AuteurMarine ecosystems and their inhabitants are increasingly under threat from climate change, competition with humans for resources, and pollution. Species that are endemic to particular currents or regions of the world's oceans have the potential [...]
Article
Gabriela Ibarguchi, Auteur ; Anthony J. Gaston, Auteur ; Vicki L. Friesen, AuteurMany seabirds exhibit high natal philopatry despite their extreme dispersal ability and delayed reproduction, and some exhibit phenotypic clustering in colonies and fostering or adoption of neighbouring chicks. Previous investigations of kinship[...]
Article
Linda A. Lait, Auteur ; Vicki L. Friesen, Auteur ; Anthony J. Gaston, Auteur ; Theresa M. Burg, AuteurThe population genetic structure of many high-latitude species in North America was affected by the last glaciation, and current structure reflects isolation in refugia and colonisation patterns. Large ice-free areas, both south of the ice sheet[...]
Article
Will S. Jeyasingham, Auteur ; Scott A. Taylor, Auteur ; Carlos B. Zavalaga, Auteur ; Alejandro Simeone, Auteur ; Vicki L. Friesen, AuteurRecent research has shown that tropical seabirds specialized to feed on cold water upwellings exhibit low population genetic differentiation and high gene flow across large geographic distances. This pattern is opposite to the general pattern of[...]
