| foraging segregation and genetic divergence between geographically proximate colonies of a highly mobile seabird. | foraging segregation may play an important role in the maintenance of animal diversity, and is a proposed mechanism for promoting genetic divergence within seabird species. however, little information exists regarding its presence among seabird populations. we investigated genetic and foraging divergence between two colonies of endangered hawaiian petrels (pterodroma sandwichensis) nesting on the islands of hawaii and kauai using the mitochondrial cytochrome b gene and carbon, nitrogen and hydro ... | 2012 | 21837410 |
| population divergence and gene flow in an endangered and highly mobile seabird. | seabirds are highly vagile and can disperse up to thousands of kilometers, making it difficult to identify the factors that promote isolation between populations. the endemic hawaiian petrel (pterodroma sandwichensis) is one such species. today it is endangered, and known to breed only on the islands of hawaii, maui, lanai and kauai. historical records indicate that a large population formerly bred on molokai as well, but this population has recently been extirpated. given the great dispersal po ... | 2012 | 22434012 |
