Fishing spiders: population structure and mating dynamics

This project focuses on understanding the population structure and mating dynamics of Dolomedes species (fishing spiders) found around the Melbourne region. By sampling individuals from multiple locations, we aim to document how populations are structured across the landscape, providing insight into patterns of gene flow and possible population isolation. To explore reproductive behaviour, we will conduct mating trials in captivity, allowing us to assess the frequency and outcomes of mating interactions under controlled conditions. Particular attention will be given to differences between males and females, as well as variation across geographic locations. These findings will help clarify how local context and sex-specific strategies shape the mating system of this semi-aquatic spider group. Our work builds upon the activities of Dr Chrissie Painting and the Invertebrate Behavioural Ecology Lab at the University of Waikato in New Zealand (https://chrissiepainting.com/), and will utilise the protocols they have developed for a global look at Dolomedes sp.
