Organisms can survive changing environments in two main ways: they can evolve new tolerances (requires genetic variability and time); or, within the lifetime of an individual, they can use their existing capacity to adapt to changing conditions.
This talk will deal with the second of these, which can be referred to as physiological plasticity, or acclimatisation. There is a widely-accepted view that, because tropical environments are less variable than conditions in temperate zones, tropical organisms have less physiological plasticity and are therefore more susceptible to the effects of global warming and climate change.
Over the past 45 years, Prof. Keith Christian has studied the physiology and ecology of amphibians and reptiles in tropical environments in South America, the Caribbean, and Australia. He will use that experience to challenge the generalisations that have been made about tropical organisms and will talk about what – if any – useful generalisations can be made.
RIEL's Prof Christian is a zoologist whose interests include the physiological and behavioural adaptations of animals – particularly reptiles, amphibians and ants – in response to their physical environment. He has published in the areas of comparative physiology, physiological ecology, exercise physiology, thermoregulatory biology, respiratory physiology, biophysical ecology, and biological control.

Boring beetles and super models: mapping the distribution of a new invader
The polyphagous shot-hole borer (PSHB) is a tiny beetle with a mouthful of a name, but it’s been making headlines as a new invasive species in Australia. PSHB was first detected in Perth three years ago and has since devastated trees across the city. There are concerns about what its further spread could mean for urban, agricultural and natural environments.

Groundwater: Hidden wonder of the Northern Territory
The seminar ‘Groundwater: Hidden wonder of the Northern Territory’ will be presented in two parts. First, Steven will provide a basic explanation of what groundwater is and concepts of how groundwater systems operate. He will then give an NT-wide view of groundwater properties and processes.

Carbon and water adventures in north Australia
With climate change and increasing land use pressures there is more and more demand for knowledge of carbon dynamics and water use as well as water resource management. Lindsay’s research is focused on providing better understanding of the biophysical environment of tropical land and water systems.
