Global change ecology and conservation
Honours projects are available across several areas of climate change ecology, global change impacts on biodiversity, planetary health, macroecology and conservation biogeography.
Climate change ecology
- Ecological requirements of marine megafauna: Identify how ocean warming drives shifts in the ecological niches of artic marine mammals.
- Coral bleaching on the GBR: Improve future projections of frequency and severity of bleaching events.
- Using paleo-archives to safeguard biodiversity: Determine ecological responses to past warming events similar to future forecasts.
- Fish diet and climate change: Establish whether diet predisposes species to increased threats from climate change.
- Climate change in Australia: Pinpoint historical periods of abrupt climate change that are compare to near-term forecasts.

Macroecology and conservation biogeography
- Native distributions of threatened mammals: Establish the natural distributions of Australian mammals in 1788 to inform future conservation management.
- Conserving megapodes: Establish responses of Australia’s megapodes to human-driven changes since European settlement.
- Ice Age Ecologist: Test retrospectively the efficacy of conservation threat metrics (such as the IUCN red list) to detect past extinctions of megafauna.

Study global change ecology and conservation
Global extinction rates have soared over the past century, due predominantly to the resource demands of a burgeoning human population.
Shifting land-use and wildlife exploitation, and elevated rates of competition and predation by invasive organisms, have reduced the range and abundance of many species.
This is directly causing severe biodiversity loss at local scales, and indirectly limiting the scope for sufficient ecological and evolutionary adaptation to future environmental change.
Understanding how biodiversity will respond to future human impacts requires innovative new approaches which explicitly couple ecological and climatic-geophysical processes.
Research in my group (Global CH.E.C.) is focused on:
- Delivering the predictive tools required to anticipate ecological responses to climate change in the context of other human-driven threatening processes.
- Identifying the mechanisms that drive range contractions. This is important for the conservation and management of biodiversity, because the contraction of a species’ distribution generally precedes its extinction.
- Determining why some species are present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete.
- Characterising current-day and potential future impacts of disruptions of Earth's natural systems on human well-being.
Our research utilises the latest developments in macroecology, climate change science and conservation biology.
