Doctoral Candidate - Doctor of Philosophy


Rebecca has a keen interest in behavioural ecology and entomology. Her broad area of interest lies with the interface between animal behaviour, ecology, and evolution, and how these are interconnected - especially in wild populations of animals. She completed her BSc at Auckland University in 2012 and continued on with postgraduate research completing her MSc in 2014. This research explored the behaviour of the New Zealand giraffe weevil, and involved analyses of their fighting and mating behaviour as well as exploring how their mating success over their lifetimes might be driving selection in a wild population.

Research | Current

My current research is focused on developing an understanding of the behavioural ecology of seaweed flies here in New Zealand. My research covers aspects of both their ecology and behaviour, most specifically their (fascinating!) mating behaviour. Seaweed flies display extreme sexual conflict and convenience polyandry, behaviours which have been widely investigated in Northern hemisphere species, however little is known about our far-flung NZ species and how they might fit in. Running alongside this I am taking a broader approach and investigating the ecology and inter- and intraspecific relationships of these seaweed flies and the wrack community they inhabit throughout NZ.
