I apply behavioural ecology to conservation management. My work has focused on scent communication in wild mammals, and recently in its application to managing carnivore movements. I am interested in the ecology and behavior of predators in human- or livestock-dominated areas, and in applying this knowledge to develop and evaluate tools to reduce human-wildlife conflict. While not limited to predators, my research interests are predator-heavy, which reflects both their importance as ‘problem’ animals (native and invasive), and the key role that they play in trophic cascades.
Developing a scent-based management tool for dingoes and other wild dogs in Australia
Management of dingoes and other wild dogs in Australia is primarily driven by the interests of the livestock industry and is typified by the use of physical barriers and lethal control, at significant cost. There is also increasing understanding that dingoes have cascading benefits on ecosystems. A more nuanced approach, with the aim of protecting livestock while retaining the ecosystem benefits of dingoes across the Australian landscape, is much needed. By collecting, chemically-characterising and experimentally testing the responses of wild dogs to multiple sources of their scent, this project will evaluate the potential for using territorial signals in conservation management. This project is a collaboration with the Department of Primary Industries, New South Wales (Peter Fleming, Paul Meek, Guy Ballard). (See below for potential honours project)
I currently conduct field research at the Botswana Predator Conservation Trust’s long-running large predator research camp on the fringes of the Okavango Delta World Heritage Site. My work focuses on developing and testing potential tools to manage the conflict between large carnivores and livestock. One aspect of this work focuses on the scent-marking behaviour African wild dog (Lycaon pictus), and whether synthetic mimics of these signals can be used to manage their ranging behaviour and reduce human-wildlife conflict. I am also developing a research programme to investigate the ecology and behavior of large carnivores in livestock areas, principally lions (Panthera leo) and leopards (P. pardus), and in applying this knowledge to develop and evaluate low-cost, locally-feasible, preventative tools to reduce livestock losses.

Potential Honours projects
The following projects are currently on offer. I am also very open to students designing their own projects that fit with my research interests. Contact me for more information.
1) Chemical and behavioural evaluation of the information in dingo scent-marks (also with A/Prof. Mike Letnic)
This project contributes to evaluating the potential of scent in wild canid management by quantifying the responses of dingoes and other wild dogs to conspecific scent-marks, including those exposed to the environment for varying lengths of time. Behavioural responses will be compared to the information content (chemical composition) of the scents to give an indication of scent longevity and signal function. The project will involve chemical analysis of scents at UNSW and potentially some fieldwork in the wild or zoo environment (recording and evaluating the responses of dingoes to scent). The student will gain skills in lab work and procedures including Gas-Chromatography Mass-Spectrometry, statistical analysis and (potentially) behavioural observations and camera-trapping.
2) Activity of African large carnivores in a livestock-dominated environment
3) Behavioural and endocrine responses of captive chimpanzees to the introduction of unfamiliar conspecifics (also with Dr Rebecca Hobbs, Taronga Conservation Society Australia).
Five female chimpanzees, Pan trogolodytes, are being gradually introduced to the established group at Taronga Zoo in Sydney, beginning in November 2015. This project will characterize and evaluate any potential impacts of this introduction on the resident group. The project is particularly focused on characterizing and measuring stress, through changes in both the behaviour and hormone profiles of members of the resident group. The project will characterize and evaluate glucocorticoid profiles of six resident chimpanzees over the course of the introductions. Complementary behavioural data will also be collected. Hormone assays will be conducted by the student at the Animal Reproduction Laboratory at Taronga Western Plains Zoo in Dubbo, where both supervisors are based, and where the student will be trained in the relevant procedures. The student will be required to spend a minimum of 8-weeks in Dubbo for this work, and will be responsible for finding and funding their own accommodation while there.
4) Platypus stress: evaluation of the effects of river flow regimes on platypus glucocorticoids (with Dr Rebecca Hobbs, Gilad Bino)
This project will take an endocrine approach to assessing the effects of river fragmentation on platypus health. It will characterize and evaluate glucocorticoid profiles of wild platypuses as part of a larger project on river fragmentation and platypus population structure. The aim is to compare endocrine indicators of stress across river systems with varying flow regimes. Faecal collection will be undertaken by collaborators in the field. Hormone assays will be conducted by the student at the Animal Reproduction Laboratory at Taronga Western Plains Zoo in Dubbo, where two supervisors are based, and where the student will be trained in the relevant procedures. The student will be required to spend a minimum of 8-weeks in Dubbo for this work, and will be responsible for finding and funding their own accommodation while there.
Over the next few years, a major focus of my work will be developing a conservation research programme within Australian ecosystems. I am particularly interested in conducting and supervising work that can be applied to the development, or directly tests the efficacy, of potential human-wildlife conflict mitigation tools. As a research fellow at Taronga Conservation Society, I am also interested in conducting research beneficial to their captive collection and conservation research strategy.
Current areas of interest include:
Students interested in pursuing an Honours project or MSc/PhD in my areas of interest should contact me directly via email to discuss potential projects. I am especially interested in students wishing to work in human-wildlife conflict.

|Abrahms et al.||2015||The context of road-use by African wild dogs highlights the importance of considering animal behaviour in conservation planning||
Roads are among the most widespread forms of landscape alteration globally, so effective conservation planning requires an understanding of how they can affect animal movement. Using novel GPS collar technology we found that the response to roads by endangered African wild dogs, Lycaon pictus, varied with behaviour as well as with habitat. African wild dogs selected roads when travelling, ignored them when running (mostly hunting) and avoided roads when resting. Road-use increased in denser habitats, suggesting that roads may enhance wild dog movement through the landscape. Overall, this work highlights the importance of animal behaviour in conservation planning. Click here for full publication.
