Brad Congdon is a field ecologist who applies ecological and evolutionary theory to the management and conservation of animal and plant species. He has a special interest in seabird conservation and has worked extensively with seabirds both in Australia and overseas. His current research is focused on understanding how changing ocean conditions impact seabird breeding success throughout the Great Barrier Reef and Coral Sea ecosystems. His research group was the first to demonstrate that seabirds are sensitive indicators of multiple climate-change impacts on top predators in these areas and have established rising sea-surface temperatures as a major conservation issue for seabirds of the Great Barrier Reef.

Wet Tropics Management Authority - Student Research Grant Scheme

Connectivity, landscape genetics and genetic diversity of the endangered northern bettong (Bettongia tropica).

Indicative Funding
I will explore how habitat quality influences connectivity in order to understand the metapopulation dynamics of an endangered ecotone-habitat specialist, the northern bettong. To do this I will obtain non-invasive genetic samples (by hair trapping) across a number of sites and measure habitat characteristics at these sites. This will allow me to quantify gene flow in relation to habitat characteristics and identify potential source-sink population dynamics. Results will be used to design best-practice management alternatives for this endangered species and will add to scientific understanding of how the environment influences population connectivity, particularly for small mammals with limited dispersal capacity.

Interactions among fungi, ants, and the ant-plant Myrmecodia beccarii

Indicative Funding
Myrmecodia beccarii is a vulnerable endemic ant-plant of far north Queensland. This ant-plant provides ants with housing in specialised tunnels and chambers. Fungi were discovered in these chambers almost 40 years ago but their identity and functional roles have never been determined. I will explore the ecological interactions among fungi, ants and M. beccarrii to establish and define this tripartite mutualism. To do this, I will conduct field work to determine the distribution of fungal species within M.beccarii and field/greenhouse experiments to investigate the interactions and functional roles of fungi. The results will be used to inform the conservation of M. beccarri.

Royal Zoological Society of New South Wales - Research Grant

The role of seagrass dispersal by marine mega-herbivores, dugong (Dugong dugon) and green sea turtles (Chelonia mydas).

Indicative Funding
$7,000 over 3 years
This project will investigate the dispersal mechanisms of tropical seagrasses and determine which mechanisms are most effective for long distance dispersal. It will examine whether marine mega-herbivores (dugongs and green sea turtles) disperse seagrass seeds through their fecal matter and whether those seeds are viable. It will determine how long seagrass fragments, created by abiotic and biotic mechanisms, remain viable and establish new meadows. This information will be used to model which seagrass meadows are at greater risk of slow recovery after a large scale loss. This recovery model will have the potential to highlight which seagrass meadows rely solely on dispersal by marine mega-herbivores for recovery.
