For present-day populations of Black-footed Albatross, analysis of mitochondrial DNA indicates significant genetic differentiation between birds breeding in Hawaii and Japan, suggesting that these two populations may be reproductively isolated despite considerable overlap in their at-sea distributions.
En ce qui concerne les populations actuelles dâ€™Albatros Ã pieds noirs, lâ€™analyse de lâ€™ADN mitochondrial indique une importante diffÃ©renciation gÃ©nÃ©tique entre les oiseaux qui nichent Ã HawaÃ¯ et ceux qui nichent au Japon. Par consÃ©quent, il y a peut-Ãªtre isolement reproductif de ces 2 populations, et ce, mÃªme si les aires de rÃ©partition en mer se chevauchent considÃ©rablement.
