Cooperative breeding and long-distance dispersal: a test using vagrant records.

摘要: Cooperative breeding is generally associated with increased philopatry and sedentariness, presumably because short-distance dispersal facilitates the maintenance of kin groups. There are, however, few data on long-distance in cooperative breeders—the variable likely to be important for genetic diversification speciation. We tested hypothesis that breeders are less engage events by comparing records vagrants outside their normal geographic range matched pairs (cooperatively vs. non-cooperatively breeding) North American species birds. Results failed support reduced among breeders. Thus, our results counter conclusion lower rate speciation taxa found recent analyses a consequence vagility.
