Behavioural, evolutionary and physiological ecology
About
Ecologists often begin by asking how interactions between individual and the environment result in differential survival & reproductive output of organisms depending on their size, age, sex & which traits they possess. These can result in predictable changes in population size and composition that, at broader scales, generates variation in gene flow among populations and differences in species ranges. Natural selection operates whenever there is variation in reproductive output because organisms differ in their ‘fit’ with the environment. Evolutionary change feeds back to affect future ecological interactions. Research at the Research School of Biology covers all aspects of the ecology-evolution cycle. Our key research strengths include: ecophysiology of plants and mammals; behavioural ecology of crabs, birds, insects, reptiles & fish; sensory ecology of crabs & insects; functional ecology of fish & plants; evolutionary genetics of microbes, fungi and reptiles; and the epigenetics of bees. We also have a strong international reputation for developing theory in evolution & ecology that transcends specific study taxa.

A new study shows Australian magpie-larks may use a ventriloquial illusion to make their vocal duets more threatening.
To measure the speed of adaptive evolution in the wild, we studied 19 populations of birds and mammals over several decades. We found they were evolving at twice to four times the speed suggested by earlier work.
The raw material for evolution is much more abundant in wild animals than we previously believed, according to new research.
The biologists and the linguists at ANU might sit on different sides of the campus, but Professor Lindell Bromham from the ANU Research School of Biology says it wasn’t difficult to see the benefits in the two disciplines coming together.
Mention the superb lyrebird, and you’ll probably hear comments on their uncanny mimicry of human sounds, their presence on the 10 cent coin, and their stunning tail. Far less known – but equally, if not more, impressive – is the Albert’s lyrebird.
A new study from researchers at The Australian National University (ANU) rolls back the curtain on half a century of evidence detailing the impact of climate change on more than 60 different bird species.

Koalas are eucalyptus folivore specialists that are heavily reliant on their gut microbiome to breakdown their high fibre, low protein diet. Here I will discuss our recent work investigating the koala gut microbiome; its role in koala health, nutrition and ecology.
