Research Themes
James’ research is aligned with the University’s research theme of Environment, Resources and Sustainability. His interests focus on the application of novel technologies and approaches to conservation biology.
His current research is on the Tasmanian wedge-tailed eagle (Aquila audax fleayi), an endangered top predator endemic to Tasmania. James’ research includes the use of high-frequency GPS-tracking to provide fine-scale information on the behaviour of these birds. This information will be used to inform the management of a number of threats to the Tasmanian wedge-tailed eagle population, including habitat loss, collisions with powerlines and wind turbines, and human disturbance. James is also exploring different methods to investigate the impacts of environmental contaminants on predatory species. Top predators are susceptible to the exposure and effects of contaminants. Understanding the routes by which predators are exposed will help inform management actions that effectively mitigate the impacts.

Aspects of the spatial and reproductive ecology of the grey goshawk in modified landscapes of Tasmania (2022)$10,000
- Description
- The aim of this study is to apply a comparative approach to gain further insights into the spatial and reproductive ecology of grey goshawks in highly modified and natural habitats, and the ways in which modified anthropogenic habitats promote or negatively impact populations or individuals of the species. The objectives in achieving this aim are: 1. Estimate and compare breeding and non-breeding home range size of adult male and female grey goshawks in modified / unmodified and wet / dry landscapes of south-east Tasmania. 2. Characterise important regional nesting habitat in modified / unmodified habitats, and develop a predictive nesting habitat model.3. Investigate spatio-temporal habitat use of adult grey goshawks to identify and characterise important foraging and roosting habitat within the home range during breeding and non-breeding seasons (eg compare use vs availability). 4. Estimate breeding densities and nest productivity in SE Tasmania from nest sites located during this study

Spatial ecology of wedge-tailed eagles in the Tasmanian Midlands (2022)$74,420
- Description
- The aim of this research is to GPS-track five adult eagles in the Tasmanian Midlands to investigate how they use this region of Tasmania. We currently have little information on the home range characteristics and habitat use of Tasmanian wedge-tailed eagles in the Tasmanian Midlands. Information on eagle behaviour in this area will be particularly important for understanding eagle habitat use at a state level, as it will reveal how the eagles utilise small patches of remnant vegetation in highly modified agricultural landscapes. We will consider the spatial ecology of the birds at two scales. First, we will investigate habitat use at the home-range scale, considering the size and characteristics of areas used. Second, we will model how Tasmanian wedge-tailed eagles select for different habitats depending on the behaviour they are exhibiting. All animal ethics and veterinary competencies will be met.

GPS-tracking Tasmanian wedge-tailed eagles (EPF) (2021) (2021)$74,420
- Description
- Wind energy represents a key renewable energy source that is increasingly utilised worldwide in efforts to reduce carbon emissions and the effects of climate change. However, wind farms have negative impacts on avifauna through injuries caused by collisions with turbines. In Tasmania, the endangered Tasmanian wedge-tailed eagle is vulnerable to collisions from wind-turbines and these incidents are expected to increase with the growing wind energy industry in the state. These collisions are a conservation concern for the species and a significant financial cost to Tasmanian wind energy companies. It is therefore a priority that efforts are made to mitigate the effects of wind energy infrastructure on the Tasmanian wedge-tailed eagle. High-frequency GPS-tracking has been used to understand the flight behaviour of raptor species threatened by wind turbine collisions in the US and Europe. These studies have created regional and local risk models that predict where high-risk flights are more likely to occur in the landscape, providing important information to guide effective mitigation. The application of these techniques to help understand and reduce the impacts of wind farms of wedge-tailed eagles is supported by state and commonwealth regulators

Estimating the population size of the Tasmanian wedge-tailed eagle (Aquila audax fleayi) using modern genetic techniques (2021 - 2022)$14,209
- Description
- This project will use modern genotyping techniques (DArTseq) and statistical approaches to estimate the effective population size of the Tasmanian wedge-tailed eagle (Aquila audax fleayi). This information will be used to parameterise a state-wide population viability analysis to improve precision of modelled predictions. The project and the associated PVA will address two research priorities identified in the Tasmanian wedge-tailed eagle recovery plan.

Coordinating conservation and research priorities for the Tasmanian wedge-tailed eagle Aquila audax fleayi (2020 - 2021)$165,000
- Description
- The threatened Tasmanian wedge-tailed eagle lacks a current Recovery Plan. The objectives of its previous Plan, which expired 2010, were to increase the species' breeding success and security by protecting nesting habitat, minimising foraging habitat modification and minimising human-related mortalities. However, new information is providing insights into additional and existing threats (e.g. lead poisoning, rodenticides, adult and juvenile mortality). Eagle management impacts many different industries, and currently the key approach to managing eagles is focused on nest sites. The conservation needs and management priorities of this species need to be reviewed to refine and build on these efforts. The aim of this project is to improve the plight of Tasmanian eagles with a coordinated and holistic approach, supported by the review and acquisition of new information on ecology, behaviour and threats.
