Reproductive consequences of natal dispersal in a highly philopatric seabird.
Natal and breeding dispersal have a major impact on gene flow and population structure. We examined the consequences of natal dispersal on the reproductive success (proportion of pairs rearing chicks) of colonial-breeding Thick-billed murres (Uria lomvia). Reproductive success increased with distanc...
