How does the eastern bristlebird population respond to fire?
Ecological disturbance is widely recognised as a major driver of community diversity, but its role in shaping patterns of genetic diversity and population patterns has largely been overlooked.
The Threatened Species Hub and The Australian National University are seeking an environmental science student to look into this role by applying their ability to independently plan and execute field-based research. Candidates with specialist skills in genetic analysis will be considered favourably.
While the eastern bristlebird population is believed to have increased in parts of Booderee National Park since a wildfire in 2003, recent evidence suggests that it is the combination of wildfire and post-fire predation by feral predators that is the most likely reason for their decline.
The successful candidate will work closely with Parks Australia and the Department of Defence in Booderee National Park to characterise the demography and genetic structure of the bristlebird population. It is anticipated that by the conclusion of the project that the student would be in a strong position to inform fire and feral predator management strategies.

Conservation managers considering the implementation of nest boxes programs need to give careful consideration to design, colour, placement and shade profile of nest boxes.
The vast brigalow forest that extended from northern New South Wales to southern Queensland has been cleared in the space of 60 years and it seems that many species have become threatened as a result. Rod Fensham and co-workers have identified the plant species that are likely to have become threatened and many of these species were not previously recognised as imperilled.
Monitoring is fundamental to good policy and effective conservation management. Data derived from monitoring underpin the process for listing of species as threatened, which is a precursor to recognition in policy.
TSR Hub researcher David Lindenmayer and colleagues embarked on a four-year case study examining the impacts of a biodiversity offset which established nest boxes to compensate for the losses of natural tree hollows caused by the widening of sections of the Hume Highway (the road linking Sydney and Melbourne).
In recent months you may have noticed some energetic public debate about what is the biggest threat to threatened species in Australia. Is it feral cats and foxes or is it the clearing and degradation of native vegetation?
