Seasonal Migration, Gene Flow, and Speciation in North American Birds
Around 20% of bird species migrate annually between distinct breeding and wintering ranges and many sedentary populations shift cyclically within a single range in response to varying climates and food availability. Migration allows populations to take advantage of seasonal resource abundance and access isolated habitat ...
Gene flow and models of avian speciation in tropical mountains
Eight decades after the modern synthesis, the role of gene flow in speciation remains contentious. Because gene flow is a homogenizing force and sister species frequently occur in allopatry, geographic isolation was assumed to be a requirement for the majority of speciation events for most of the 20th century. More recently ...
