Abstract

The Noisy Miner (Manorina melanocephala) is a common, cooperatively breeding meliphagid of eastern and southeastern Australia. We used DNA microsatellites to examine the apportionment of genetic diversity in Noisy Miners at disparate geographic scales to generate baseline information about the population genetic structure of this species. We examined five loci for 79 individuals from four populations. We found small amounts of genetic differentiation between paired populations separated by 30–40 km, and more substantial and significant differentiation between populations separated by more than 1000 km. This result implies substantial gene flow on local scales but much less at regional levels, probably reflecting short dispersal distances and isolation by distance.

Análisis Jerárquico de la Estructura Genética Poblacional de Manorina melanocephala Utilizando Marcadores de ADN Microsatelital

Resumen.Manorina melanocephala es un melifágido común del sur-este de Australia que presenta cría cooperativa. Utilizamos ADN microsatelital para examinar la distribución de la diversidad genética de M. melanocephala a diferentes escalas geográficas para generar información básica sobre la estructura genética poblacional de esta especie. Examinamos 5 loci en 79 individuos pertenecientes a cuatro poblaciones. Encontramos una baja diferenciación genética entre pares de poblaciones separadas por 30–40 km, y una diferenciación más substancial y significativa entre poblaciones separadas por más de 1000 km. Estos resultados sugieren un alto grado de flujo génico a escala local, el cual es mucho menor a nivel regional, lo que probablemente refleja distancias de dispersión cortas y aislamiento por distancia.
