GENETIC DIFFERENTIATION OF THE KITTLITZ'S MURRELET BRACHYRAMPHUS BREVIROSTRIS IN THE ALEUTIAN ISLANDS AND GULF OF ALASKA

摘要: SUMMARY BIRT, T .P ., MACKINNON, D PIATT, J .F . & FRIESEN, V .L 2011 Genetic differentiation of the Kittlitz’s Murrelet Brachyramphus brevirostris in Aleutian Islands and Gulf Alaska Marine Ornithology 39: 45–51 Information about distribution genetic variation within among local populations is needed for effective conservation this rare declining species We compared a 429 base pair fragment mitochondrial control region 11 microsatellite loci 53 Murrelets from three sites western (Attu Island) (Glacier Bay Kachemak Bay) found that birds these two regions differ genetically assessments: (1) global pairwise indices were significantly greater than zero, (2) haplotypes differed by minimum nine substitutions, (3) molecular assignments indicated little gene flow between The data suggest have been isolated an extended period conclude Attu Island represent separate evolutionarily significant units, should be treated as such remainder breeding range are urgently
