Re-colonization dynamics of an aggressive species: understanding population movements through gene flow and sex ratio variation in the Noisy Miner (Manorina melanocephala)
In this project, I will investigate population dynamics, genetic structure and connectivity of the Noisy Miner (Manorina melanocephala) across fragmented woodlands in two regions of central New South Wales. Noisy Miner's preference for human-altered landscapes has seen the species increase in density throughout its range, and as such increase the negative influence that it has on avifaunal biodiversity throughout south-eastern Australia.
The objective of this research is to understand how relatedness patterns, both within and between colonies, shape population movements and dispersal in this social bird. Experimental culls of Noisy Miners have seen rapid re-colonisation of the cleared sites within 24 hours, indicating that gaining a firm understanding of gene flow and population viscosity between fragments is urgently needed to inform management practice.
