GENETIC VARIABILITY AND POPULATION DIFFERENTIATION INFERRED FROM DNA FINGERPRINTING IN SILVEREYES (AVES: ZOSTEROPIDAE).

摘要: This study evaluated DNA fingerprinting as a tool for estimating population genetic diversity and differentiation by comparing minisatellite variation in island mainland populations of silvereyes (Aves: Zosterops lateralis). Three with different recent histories were compared: (1) Heron Island neighboring islands, colonized 3000 to 4000 yr ago; (2) Lady Elliot Island, within the past two decades; (3) an adjacent population, which presumably has existed thousands years. The degree variability three reflected both their size time since colonization. Minisatellite was highest intermediate Capricorn group (which shown represent single admixture), lowest possibly because bottleneck during Mean band sharing between any less than mean either those populations, four fingerprint bands common birds rare or absent fingerprints birds. In absence significant gene flow have apparently become distinct at loci, evidenced differences allelic frequencies specific fragments. Within cohort analyses demonstrated temporal stability profile over 6 yr. demonstrates that length polymorphisms loci may be stable enough retain information about historical demographic effects on relative small, closely related populations.
