About

My research examines broad ecological and evolutionary questions, including applied problems.  I take an integrative approach, using a combination of controlled experiments and observational studies to test hypotheses.  Much of my research has used reptiles and amphibians as model systems, but I am broadly interested in a variety of groups.

I am interested in the relationship between vertebrates and habitat structure, and study habitat use and shelter site selection, predator avoidance and thermoregulation, as they relate to habitat.  These interests have lead me to study the influence of various anthropogenic effects, such as logging, grazing, and weeds and their control, on vertebrate populations. 

The amphibian disease, chytridiomycosis, is strongly influenced by the environment selected by host amphibians.  Thus, behaviour and habitat selection by amphibians have important effects on disease dynamics in this system, and these relationships have drawn me to study this system in collaboration with colleagues at JCU and elsewhere.

Invasive species, as predators, prey and competitors can have negative effects on native species.  With an industry partner I have developed a trap that exploits the signalling system of invasive amphibians to selectively remove mature reproductive individuals from populations, as a means of local control for these pests. 

Adaptation to environmental pressures has lead to many amazing animal charactersitics.  Lizard skin shows adaptations ranging from high to low adhesivness and from superhydrophobicity to rapid water transport, depending on species and their environments.  I have been examining these traits with collaborators in chemistry and physics at JCU, and from the University of Idaho.

Understanding population growth time lags in invasive species: Chital deer as a model system

Indicative Funding
$394,015 over 5 years, in partnership with QLD Department of Agriculture and Fisheries ($80,000)
Summary
Lags in population growth of introduced species are common, but poorly understood. Chital deer (Axis axis) are an invasive species introduced to Australia over 130 years ago, but their numbers have only increased dramatically in the past 30-40 years. We will use data collected from wild animals, landholder surveys, and computer simulation models to clarify causes of sudden population expansion in more detail. Understanding lags will allow us to understand their causes, and better control populations of invasive species. By predicting drivers of rapid population growth, we can better mitigate the associated economic and environmental costs of invasive species.

Tackling Frog Disease

Indicative Funding
$155,000 over 9 years
Summary
Chytridiomycois is one of the most dramatic and important emerging infectious diseases in wildlife. It is caused by a fungal pathogen (Batrachochytrium dendrobatidis or Bd), which parasitizes the skin of amphibians. This highly contagious pathogen has been responsible for making frogs the most endangered vertebrates on earth. Remarkably, some populations that experienced drastic declines have recovered, and now appear to coexist with the fungus, but the nature of their recovery remains a mystery. There are a a range of possible complex and interacting reasons why frog populations may coexist with this disease, which could be evolutionary, behavioural, environmental, or ecological. We are examining possible reasons for coexistence, to find approaches to aid populations that persist but are not recovering.

Greater glider (Petauroides Volans) mechanisms for adaptation in extreme environments

Indicative Funding
$44,500 over 8 years
Summary
Greater gliders north of the Tropic of Capricorn are half the size of those occurring in southern Australia and may constitute a subspecies. The mechanism behind these size differences in endotherms is highly controversial. The prevailing theory is heat conservation, due to a decreased surface area to mass ratio in larger animals; however alternative mechanisms have been suggested. This study will be the first to examine divergence in their phylogeny, physiology and differences in thermal tolerance between populations ranging from tropical to temperate forests. Underlying mechanisms will be investigated including water/nutrient availability, seasonality, thermal responses, microhabitat, insulation, and predator/competitor pressure.

Australian Acoustic Observatory: A Network to Monitor Biodiversity

Indicative Funding
$927,000 over 8 years (administered by QUT)
Summary
Acoustic sensing is transforming environmental science by recording vocal species 24 x 7, providing data of unparalleled spatial and temporal resolution for ecosystem monitoring and research. This is particularly relevant to Australia's fragile and mega-diverse environment and Australia has leading research expertise in this emerging field. The proposed observatory will be the world's largest terrestrial acoustic sensor network comprising 450 listening stations deployed across Australia. Funds will purchase autonomous sound recorders and online storage and processing hardware. Data will be freely available to all online, enabling new science in understanding ecosystems, long-term environmental change, data visualisation and acoustic science.

Elliot Springs ? Offset Management Plan compliance for Black-throated Finch Scientific Study

Indicative Funding
$60,000 over 3 years
Summary
We will be determining the efficacy of using remote acoustic monitoring tools for black-throated finches (southern subspecies), by deploying automated recorders for one week each in a variety of locations around Qld where black-throated finches may occur, and manually surveying these areas once at the beginning of deployment and once at the end. Acoustic recordings will be analysed using human listening and automated artificial intelligence screening for black-throated finch calls. The results from the two methods will be compared to determine if acoustic monitoring is sufficient to monitor the occurrence of these finches in various locations.

Ecological influences on biodiverse morphology in climbing geckos

Indicative Funding
$6,670 over 1 year
Summary
Ecological interactions are one of the main drivers of biodiversity generation. The influence of ecology on the morphology of organisms is one such interaction that influences the generation of biodiversity. Australian Diplodactyline geckos are some of the most morphologically and ecologically diverse systems in the world. They occupy a diverse range of habitats and have evolved unique toe pads enable the exploitation of several substrates within the habitats they occupy. Therefore, my project will investigate how toe pads have evolved in response to habitat use in Diplodactyline geckos. We will examine these relationships by studying habitat use and morphology, with locomotor performance as an intermediary link.

Gecko Repeller Spray Test

Indicative Funding

Summary
We will be determining the efficacy of a repellent spray for geckos developed by Pestrol. We will first test overall efficacy in part one of the grant, and if the substance works to repel geckos from shelters, we will further test the length of time it works for and whether geckos become habitutated to the substance.

Investigating the interaction between giant tortoises and farms in Galapagos

Indicative Funding
$50,000 over 3 years
Summary
Endangered giant tortoises migrate to the highlands for access to important resources. The highlands, however have mostly been converted to support agriculture leaving few natural areas for tortoises to use freely. Because of this, tortoises regularly enter farms, causing conflict. Our aim is to better understand how tortoises use farms as part of their migratory movements and how this affects both tortoise ecology and farm outputs. An improved understanding of the needs of both tortoises and farms will be used to mprove management practices for the Galapagos National Park and farmers.
