My introduction to ecology and conservation came as a study abroad experience in Queensland's rainforests, after which I found that plans for medical school paled in comparison to an environmentally-oriented career. I earned a Masters in Public Health degree in Environmental Health at the University of California-Berkeley and consulted for a non-profit environmental organization for three years.  I interned at a field study school in Kenya for a year, then traveled around the world before settling down to earn my Ph.D. at Cornell University. While there, I became interested in biological invasions as a conservation issue, particularly invasions by easily overlooked creatures. Upon completing my Ph.D., I went to Mauritius on an NSF fellowship to research ant invasions in a restoration context. An ARC-Discovery grant on biological invasions and conservation in an urban context brought me to Western Australia in 2005. I started at JCU in 2013, in the shadow of the rainforest where I got my ecological start.

  • I am interested in how human-induced environmental changes affect interactions among species, particularly those between plants and insects. These relationships fascinate me because they drive many of the ecological processes in the world around us, and yet are often overlooked. Much of my research has investigated invasive social insects and how their interactions differ from native species, in particular, how they enter into new, or disrupt existing, mutualistic interactions with other insects or plants. Answering these questions not only advances our understanding of biological invasions and potential to mitigate their effects, but adds to our knowledge of community and trophic ecology and the ecology and evolution of mutualisms. I primarily use field-based experimental approaches to answer questions that are relevant to conservation and restoration.

Australian Government Department of Agriculture, Water and the Environment - Advancing Pest Animal and Weed Control Solutions Competitive Grant Round

Applying environmental DNA (eDNA) methods for Yellow crazy ant detection, a sensitive and less labour-intensive approach to invasive ant detection.

Indicative Funding
$629,505 over 3 years
Invasive invertebrates in Australia are estimated to impact agricultural production losses by $4.7 billion annually and cost up to $8 billion annually considering all impacts and expenses. More specifically, invasive ants are a significant threat to agricultural production, biodiversity, tourism, personal property, and local business and industry. Current methods for invasive ant detection (i.e. baited traps or cards, pitfall traps, and detection dogs) rely on trapping, smelling, or sighting active individuals and are therefore labour-intensive, costly, and highly reliant on weather conditions. The proposed project will apply environmental DNA methods for yellow crazy ant (YCA) detection. YCA has been listed as a high priority species under the National Invasive Ant Biosecurity Plan 2018-2028, and will be used as a case study. The proposed methodology could be applied to the existing infestations and taken up by farmers, as well as being applied to other terrestrial pests.

Invasion Alert?A Machine Learning-based Platform for Invasive Ant Detection and Recognition

Indicative Funding
$61,368 over 2 years (administered by Murdoch University)
For control/eradication measures to be effective, early detection of invasive ants is essential. Current conventional methods require taxonomic expertise and are time and labour intensive. This project will develop a vision-based platform that uses machine learning for the real-time detection and identification of established invasive ants in Australia. This will provide an automated, cost-effective monitoring tool that can speed up the detection and identification process, thus enable efficient and timely response to the potential spread of these species.

Investigating combined stressors in bees: insecticides and thermal stress

Indicative Funding
$1,224 over 1 year
Insecticide use poses a risk to non-target insects including bees. The effects of these compounds is all the more worrying given that honey bees prefer nectar containing traces of the naturally derived insecticide class ? the neonicotinoids. This project will expand upon previous bodies of work to investigate the preference of stingless bee species Tetragonula hockingsi when provided with the choice between an insecticide laced food source and a sucrose solution. This project will also explore the combined effects of insecticide exposure and increasing temperature on bees.

The role of drought-stress and insect attack on rainforest plant health

Indicative Funding
$395,000 over 3 years
This project aims to examine the vulnerability of tropical plants to drought and insect attack in a large-scale field experiment. We will pioneer a new research approach that focuses on the causes and stages of decline in plant health prior to death, in order to identify the characteristics of plant species that make them more susceptible to drought and insect attack. Expected outcomes of this project include an improved capacity to predict the function and composition of future forests. This project will provide significant benefits to communities concerned with the direct and indirect effects of droughts in protected areas, forestry reserves and agriculture.

Do functional traits predict composition of ant communities attracted to different bait types in a Wet Tropics rainforest?

Indicative Funding
$1,814 over 1 year (administered by Skyrail Rainforest Foundation)
Native ants are a diverse and crucial part of rainforest ecosystems. My project aims to determine which functional traits of ants may predict the composition of any communities attracted to various bait types used in invasive ant management. The project includes field and lab components and the SRF grant will assist in paying for vehicle hire costs and other associated project costs. The results of the project will assist land managers to choose invasive ant control methods that minimize impacts of bait application on native ant communities. The results have application in the Wet Tropics and in tropical rainforests elsewhere.

Will pathogen transmission to native stingless bees be exacerbated by climate change?

Indicative Funding
$1,000 over 1 year
I will investigate the conditions under which the pathogen Nosema ceranae can remain viable on flowers, specifically whether temperature can affect virulence of N. ceranae in the Australian native stingless bee, Tetragonula hockingsi. As N. ceranae has been found to cause T. hockingsi to die at three times the normal rate, this could have landscape-scale effects if more native stingless bees are dying earlier, ultimately affecting biodiversity in the region.

Eco-Evolutionary dynamics in the invasive ant Anoplolepis gracilipes: the role of colony fragmentation and subsequent differentiation in population regulation

Indicative Funding
$5,600 over 1 year
The proposed project has 3 objectives: 1) Use genotyping and behavioural assays to reveal effects of genetic diversity within and between populations of YCA from Queensland and Borneo their ecological dominance and population dynamics. 2) Test for changes in life history (e.g., production of sexuals and workers) and defense traits (worker size, venom profile) in response to increased mortality due to eradication measures or environmental conditions (competitive environment) by comparing treated and untreated YCA colonies and colonies from different regions. 3) Conduct crossbreeding experiments with colonies varying in their spatial and temporal separation to test whether spatial separation of populations, either due to eradication measures or incursions to different locations, results in reproductive isolation.

Yellow Crazy Ant Eradication In And Next To The Wet Tropics World Heritage Area

Indicative Funding
$178,500 over 3 years
This project aims to eradicate a recent 400ha invasion of yellow crazy ants (YCA) south of cairns which have spread from coastal cane farms into the Wet Tropics World Heritage Area (WH Area). YCA are listed among the world's 100 worst invaders and are a national priority under the Tramp Ant threat Abatement Plan. These ants can have a severe impact on a range of ecological processes and lead to significant loss of biodiversity. If their spread is left unchecked, eradication will not be possible. They will eventually threaten many of the area's endemic, rare and endangered species. The ants will also threaten the tourism industry and visitor enjoyment of the WH Area, the quality of life for local residents and agricultural productivity.
