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, first as a DECRA recipient researching ecological effects of bee disease. I have since contributed to various projects that apply ecological theory to addressing real-world challenges.

  • 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.

Entomological Society of Queensland - Small grants scheme

Investigating the pitfalls of bee hotels

Indicative Funding
$2,000 over 4 years
Concern for bees among the public has led to the augmentation of habitat for bees including the addition of bee hotels. Bee hotels are often claimed to increase bee diversity and abundance. However, they artificially aggregate nesting sites above densities naturally available for bees, which could lead to increased prevalence of pathogens, viruses and parasitism, and higher predation rates. Properly controlled experiments to investigate these threats are limited, and none have been conducted in the tropics. This project investigates whether the density of nesting spaces in bee hotels affects predation rates and pathogen and parasite prevalence in cavity nesting bees.

Plant-animal interactions of passion flowers in the Australian Wet Tropics.

Indicative Funding
$4,984 over 3 years
My project will investigate the plant-animal interactions of native and invasive passion flowers in the Wet Tropics. Specifically, I aim to determine and compare the pollinators, herbivores and ant defenders of native and invasive Passiflora species. My research will have important implications for the conservation of native species, and for the control of invasive weeds that threaten native ecosystems. It may reveal native species at risk due to the spread of invasive weeds and/or a newly introduced butterfly species. The project will also provide new knowledge to inform the current biological control program for the weed, stinking passionflower.

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 4 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.

Near-infrared spectroscopy to improve detection of the invasive yellow crazy ant, Anoplolepis gracilipes.

Indicative Funding
$4,524 over 1 year
This project aims to develop a proof-of-concept device capable of distinguishing the invasive yellow crazy ant from native ants in the Wet Tropics World Heritage Area using a miniaturised near infrared (NIR) spectroscopic sensor. I will conduct an initial study into the variability of the yellow crazy ant NIR spectra then build a classification model to distinguish yellow crazy ants from common native ants using NIR spectra. These studies will be used to inform the prototype development. Prototype development will consist of the design and manufacture of a printed circuit board containing the NIR sensor and its support electronics. This prototype will be then validated using the same classification experiment of YCA against native ants.

Investigating the effects of insecticide exposure, pathogens, and heat stress on bee diversity, abundance, and health

Indicative Funding
$4,940 over 1 year
Bees are threatened by multiple stressors including insecticide exposure, disease, loss of habitat, and climate change. Studies investigating stressors facing Australian bees are becoming more common, but many knowledge gaps still exist and while some studies document the effects of stressors in isolation, they stop short of investigating the effects of stressors in combination. My project will investigate how the stressors of insecticide exposure, pathogens and heat stress affect native bee diversity, abundance, and health, as well as investigate whether bee hotels cause increased pathogen and parasitism prevalence, and predation rates in native bees.

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.

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.

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.

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.
