摘要: The abundance of New Zealand subantarctic southern right whales (Eubalaena australis) was estimated for the first time using mark-recapture methods based on photo-identification and microsatellite genotyping (13 loci). Individual identification photographs 383 genotypes 235 were collected during annual austral winter field surveys from 1995 to 1998. Given 4-year survey period lack geo- graphic demographic closure, we super- population POPAN Jolly-Seber model implemented in software programme MARK. Models with constant survivorship but time-varying capture prob- ability probability entry into most suitable due design. This provided estimates 1998 908 non-calf (95% C.L. = 755, 1,123) 910 641, 1,354) genotype data sets. current estimate 900 may represent less than 5% pre-whaling waters.
