Summary: | Migratory connectivity is a term used to describe how breeding populations are geographically connected to winter populations for a migrating species. Determining the strength of migratory connectivity is important for a number of basic and applied research questions related to the ecology and evolution of migratory species. Population genetics, particularly neutral genetic markers, are often used to measure migratory connectivity for species that are too small to carry transmitters. Previous analyses of genetic variation in the American redstart (Setophaga ruticilla), a Neotropical-Nearctic migrant that breeds in North America and winters in Middle America, revealed unique mitochondrial haplogroups mostly restricted to Newfoundland. I determined the geographic distribution of this population in winter and whether it remains separate or intermixes with other populations of redstarts on the Caribbean winter range. To assess the migratory connectivity of the Newfoundland haplogroup, I sequenced the ... |
