Dr Therésa Jones

Principal Investigator

My main area of research is in the field behavioural ecology with a particular focus on understanding the causes and consequences of variability in mating systems, the role of chemical cues, and most recently the impact of artificial night lighting on individual fitness and community structure. I completed my undergraduate at Imperial College of Science, Technology and Medicine (UK) and my PhD at the Institute of Zoology (UK). During my PhD, I spent a year at the Instituto Evandro Chagas in Belém, Brazil carrying out field observations and experiments. I commenced postdoctoral research in 1999 at Uppsala University (Sweden) exploring alternative male mating strategies in vertebrate (the ruff, Philomachus pugnax) and invertebrate (Hawaiian Drosophila) lekking species. In 2001, I was awarded a Royal Society Travelling Fellowship to conduct research at the University of Melbourne where I have worked since, first as a postdoctoral research fellow with Prof Mark Elgar for six years and then as a Melbourne University Research Career Interruption Fellow. I am currently employed as a senior lecturer in the School of BioSciences. In addition to my passion for behavioural ecology, I am a strong advocate for gender equality in Science Technology Engineering and Mathematics (STEM).

Hopkins 2015Dr Gareth Hopkins

Postdoctoral Fellow

I am an evolutionary ecologist broadly interested in how organisms are affected by, and respond to, stressors in their environment, both natural and anthropogenic. This research spans multiple layers of biological organization, from the behavioural and physiological responses of individuals to the evolutionary responses of populations and the ecological responses of communities. I am particularly interested in the role of individual variation in shaping these responses. I completed my bachelor’s degree in Biology and Natural Resources Management at the University of Northern British Columbia (Canada), and my PhD in Ecology at Utah State University (USA). Throughout this time I have worked on the behaviour, ecology, evolution, and conservation of a variety of insect and amphibian species, ranging from weevils and dragonflies to frogs and newts. In the Jones lab, I am studying the effects of artificial light at night on insects both at the community and individual level, and am particularly interested in effects on communication, behaviour, and sexual selection in the Australian black field cricket, Teleogryllus commodus.

The evolution of facultative parthenogenesis in the Australian spiny leaf insect (Extatosoma tiaratum)

The evolution of sexual reproduction and parthenogenesis has been a great debate in evolutionary biology for the previous decades. In theory, sexual reproduction is associated with various costs (such as the ‘two-fold cost’ of producing males), yet it is the usual form of reproduction among most organisms. Many theoretical models have provided evidence of benefits that can outweigh these substantial costs and give sex a net advantage, but experimental tests of the theory are scarce and often reveal contradictory findings. The Australian spiny leaf insect or Macleay’s Spectre (Extatosoma tiaratum) is a promising system in which to investigate the evolution of sexual reproduction and facultative parthenogenesis, as females mate with males when possible, but also have the ability to reproduce parthenogenetically in the absence of males. The evolution of facultative parthenogenesis in turns is not well understood, but traditionally it has been associated with male limitation. My thesis utilizes a range of approaches, from behavioural ecology to molecular biology, to investigate the evolution of this unique mating system and compare costs and benefits of sex.

Mate choice in orb weaving spiders

My research focuses on orb-weaving spiders in the genus Argiope. Among other questions I am interested in investigating environmental factors which shape the expression of web-based pheromones. In my PhD I am investigating how diet influences web-based pheromones in other Argiope species and its consequences for mating and foraging strategies. I am using a combination of behavioural assays and chemical analyses to fully investigate how diet shapes the expression of these cues.

The biological impacts of ecological light pollution on crickets

The presence of artificial light at night is increasing globally, yet the impacts that this can have on the environment have only relatively recently been given attention. My PhD continues the work that I undertook for my Masters of Zoology degree (2012-2013), exploring the biological impacts of exposure to artificial light at night (ALAN) in the Australian black field cricket. My focus is investigating the effects of ecologically relevant levels of ALAN on immune function, life history traits and behaviour, and the overall impact these have on individual fitness. A key aim of my research is to explore the possible mechanistic link between ALAN induced reductions in fitness and the biologically ubiquitous compound, melatonin. Being aware of the consequences of artificial light at night and understanding the mechanistic links behind them will provide a critical foundation for the future development of sustainable urban lighting strategies that will need to balance the potential conflict of growing human demands for brighter night lighting with the adverse ecological effects this may promote.

The links between artificial light at night and oxidative stress

My research interest is on the impact of artificial light at night (ALAN) on the fitness of organisms. I will be using Drosophila as a model species to measure the fitness implications of different intensities of ALAN. My research will focus on the physiological changes that ALAN causes due to the disruptive effects of ALAN on melatonin production. Melatonin is a powerful antioxidant that mops up reactive oxygen species (ROS) produced by normal metabolic processes. When an organism’s ability to deal with ROS gets out of balance with ROS production, the result is oxidative stress. Oxidative stress can affect proteins, lipids and DNA. Many studies have shown the impacts of oxidative stress on life span, ageing, fertility, immunity and offspring viability. I plan to investigate the impacts of ALAN over successive generations of Drosophila using a range of behavioural and physiological assays.

Evolutionary ecology of the Australian Heliozelidae (Adeloidea; Lepidoptera)

Heliozelidae are a poorly studied family of tiny day-flying moths that are extraordinarily diverse in Australia.  Based on field data and museum collections, there are almost as many undescribed genera unique to Australia as there are in the rest of the world. Their distribution spans widely diverse ecosystems, from arid regions to temperate rainforests, yet their ecological role is largely undetermined.  The aim of my PhD is to document the evolutionary history and diversity of the Australian Heliozelidae using a combination of molecular, morphological and ecological data. I will use a range of conventional and advanced methods, such as live rearing, taxonomic dissection and next generation sequencing in order to study this intriguing family. My research will form the foundation for a comprehensive revision of this family and inform conservation strategies for both the moths and plants they pollinate.

The circadian impact of artificial night lighting in black swans (Cygnus atratus)

My research is investigating the impact of artificial light at night (ALAN) on the circadian (day-night) rhythms of urban birds. I am particularly interested in how ALAN affects sleep, production of the hormone melatonin, and the timing of activity. Most of my research is focussed on an urban population of black swans (Cygnus atratus) at Albert Park Lake, in Melbourne. These swans are exposed to high levels of ALAN from street lights, sports facilities, cars, restaurants and sky glow, and I hope to learn how night lighting affects their behaviour and health..

Evolution of nocturnal singing in the willie wagtail and the effects of urbanisation upon this behaviour

After completing my masters research examining natural variation of behaviour between individuals in a bird species, I began to wonder how environmental factors may also influence behaviour. Environmental factors related to urbanisation are of particular interest to me as urbanisation affects wildlife worldwide. Using willie wagtails (Rhipidura leucophrys) I will examine whether factors such as artificial light at light (ALAN) and traffic noise influence behaviour (with a focus on singing behaviour). Willie wagtails are a particularly useful species to examine this question as they are known for singing at night (when ALAN is in action). Nocturnal singing is a relatively unusual behaviour, and as such I will also seek out the evolutionary drivers behind this phenomenon. I aim to discover if urbanisation affects nocturnal singing, through both observational and experimental methods, and to also examine various hypotheses that may explain the evolution of nocturnal singing and its fitness effects.

Food choice in a native caterpillar pest

I am passionate about all animals, but I particularly like insects and spiders. I also like plants, and was able to find the perfect project. My Masters of Bioscience research project is investigating the food choice of the black slug cup moth (Doratifera casta). The caterpillars of this species consume leaves of the Blue Mallee eucalypt (Eucalyptus polybractea), which is the plant harvested for eucalyptus oil in Australia. My project will specifically look at whether female moths are more likely to oviposit on certain individual plants over others, based on chemical composition of the leaves. If an attractant or deterrent chemical is found in the leaves, companies planning to create large plantations of Blue Mallee can prevent large outbreaks of the caterpillars by planting trees that will not be preferred by the adult female. Thus little to no pesticides will be necessary to control this species, a cost-saving measure for the harvesting companies and a more environmentally friendly choice.

Effects of artificial light at night (ALAN) on invertebrate community composition and abundance

Street lighting is a ubiquitous source of urban light pollution, yet its effects on local wildlife – in particular at the community level – are poorly understood. Still less understood is the extent to which different lighting technologies may impact on faunal communities in the short and long term. By sampling aerial and terrestrial invertebrate communities under different street lighting treatments, my masters project aims to identify how the presence or absence of street lighting impacts on the composition and abundance of local invertebrate communities, and whether the nature and extent of those impacts varies with changes in lighting technologies.

Responses of a nocturnal orb-weaving spider to artificial light at night

The presence of artificial light at night (ALAN) in cities is a growing ecological concern, but how this might influence trophic interactions is poorly understood. While there is growing evidence of the physiological costs of ALAN, there is also some evidence of nocturnal insectivores benefiting due to the attraction of insects to these lights. Orb-weaving spiders are major predators in many terrestrial ecosystems, having considerable effects on their communities. I will investigate the behavioural and physiological consequences of ALAN on the nocturnal Australian garden orb-weaving spider (Eriophora biapicata) by measuring the fitness and foraging consequences over their 12-month lifespans. By providing insight into how these predators are affected by artificial light, I will improve our understanding of how this light impacts urban ecosystems more generally. My project will involve textiles, plastering, carpentry, soldering and light installation, food preparation, spider husbandry, waste removal, and a little bit of biology.
