Global change biology, climate change ecology & macroecology
Honours projects are available across several areas of climate change ecology, global change impacts on biodiversity, species range dynamics and extinction processes.
- Coral bleaching on the GBR: Improving future projections of frequency and severity of bleaching events.
- Fish diet and climate change: Does diet predisposes species to increased threats from climate change?
- Drivers of the edge of the range: Establish the determinants of the range limits of antilopine wallaroo
- Ice Age Ecologist: Test efficacy of conservation threat metrics to detect past extinctions.
- Climate change in Australia: Identify historical periods of abrupt climate change and compare with forecasts
Study global change biology; climate change ecology & macroecology
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 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.
Our research utilises the latest developments in quantitative ecology, paleoclimatology, geochronology and genomics.
