Assoc Prof. Rohan Clarke

REC group Principal Investigator​​

​

Rohan lectures in Ecology and leads the REC group in the School of Biological Sciences at Monash University. His research interests focus on conservation biology and ecology, especially as they relate to best-practice strategies to reduce the impact of threatening processes on biodiversity. Within these areas of interest, research is conducted at a variety of levels from organismal ecology to ecosystem ecology. Ultimately, the REC group's research programs aim to deliver actions that address the biodiversity crisis and respond to climate change as two of the biggest challenges our modern world faces.  

 

Current research programs include:

• Whole-of-island restoration in the eastern Indian Ocean and Pacific Ocean

• Mitigating wildlife interactions with Australian wind energy developments

• Conservation research programs for tropical seabirds in Australia and Melanesia

• Management of threatened bird species on Norfolk Island

• Management of threatened woodland birds in south-eastern Australia

• Avian pathogen movement within Australia's important bird migration corridors

​

Like most members of the REC group, Rohan combines healthy doses of fieldwork with a diversity of field, lab and desktop techniques to achieve the group’s research objectives.

Luke recently completed his PhD at Monash University, studying the conservation of threatened and Data Deficient Australian skinks. Aside from his PhD, Luke has contributed to numerous ecology and conservation research projects worldwide including studies on Darwin’s finches in the Galapagos Islands, small mammals in western Victoria, the Critically Endangered helmeted honeyeater and even the mammal fauna of Paraguay. Through his experiences, and keen interest in threatened species conservation, he has developed varied skills in ecological fieldwork and laboratory practice, as well as strong knowledge of research principles.  

In his spare time, Luke enjoys using his wildlife photography kit to photograph vertebrates (particularly Australian birds), and often spends his weekends hiking and embracing the outdoors.

Dr. Mark Miller

Post Doctoral Researcher

​

Mark is a Research Fellow currently investigating potential offshore wind farm impacts on southern hemisphere seabirds. His role focuses on building the knowledge base for seabirds in order to reduce uncertainty in offshore wind farm impact assessment. To achieve this, Mark designs field studies (e.g. albatross biologging) and evidence reviews that return chunks of information to plug knowledge gaps in the impact assessment process.

 

Mark holds a PhD in seabird ecology from James Cook University and brings postdoctoral research and industry experience to the lab. He has broad interests across ornithological research, marine functional ecology, biologging, remote sensing, and spatial modelling (https://github.com/lark-gorilla).

Dr. Michelle Gibson

Post Doctoral Researcher

​​

Michelle is interested in understanding ecological disturbances and how to conserve and manage resilient ecosystems into the future. Originally from California, she has worked in Mediterranean ecosystems in the southwest U.S.A. and South Africa’s Cape region conducting research on invasive plants, pollination, and human disturbances on bird communities. Her work in Australia has involved desert bird ecology, measuring effectiveness of restoration actions for Australian woodland birds, and understanding the effects of bushfires and planned burning on bird communities across Victoria.

 

Her current research involves managing the restoration of Phillip Island, a subtropical seabird island 6km south of Norfolk Island and roughly 1500km off the coast of southeast Queensland, in collaboration with Parks Australia. Phillip Island is home to a suite of endemic plant and animal species that still exist despite a recent history of introduced goats, pigs, and rabbits, which devastated native vegetation cover before being eradicated. This project aims to understand the most effective approaches to restore Phillip Island’s native ecosystems, primarily through weed control, revegetation and soil stabilisation, and monitor its native biodiversity.

Dr. Donal Smith

Post Doctoral Researcher

​

Donal is interested in the conservation and recovery of threatened species and degraded ecosystems. He has joined the Research Ecology Lab to manage the restoration of Browse Island off the Kimberley Coast. Once brimming with breeding seabirds and turtles, Browse Island was devastated by guano mining in the late nineteenth century, and further impacted by the arrival of the Asian house mouse. This project aims to understand and address the factors limiting recovery of the island’s ecosystem, and act as a model to inform similar restoration projects.

Donal seems fond of birds and islands - having spent years working with the echo parakeet in Mauritius and the hihi in New Zealand: projects that demonstrate how powerful direct conservation action can be in helping populations recover. This has motivated his broader research into the conservation of species on the very brink and those that have become extinct in the wild

Dr. David Clarke

Post Doctoral Researcher

 

David is currently a postdoctoral researcher with the McGeoch Research Group, and affiliated with the ARC Special Research Initiative Securing Antarctica’s Environmental Future (SAEF), at Monash University. Generally speaking, he is interested in and working on the measurement and monitoring of biodiversity. Specifically, he is currently employing a biodiversity informatics approach to provide an improved spatio-temporal characterization of the status and trends in Antarctic biodiversity.

Dr. Finella Dawlings

Post Doctoral Research Fellow & Collaborator

​​

Dr. Finella Dawlings joined the REC group as an undergraduate to undertake a research project describing the trajectory of seabirds in the Bonney Upwelling over 38 years. She then conducted her Honours project on the breeding ecology and nesting threats of Norfolk Island Robins. She used camera traps to determine the nest success rates and threats to nesting success of the NI Robin, and used thermal cameras to determine invasive rodent densities in the national park.

 

During her PhD, she investigated the use of remote sensors to improve monitoring and ecological understanding of Australian wildlife for the purpose of conservation. She used drones and thermal scanners to develop monitoring techniques and study threatened wildlife, including the Plains-wanderer, Fat-tailed Dunnart and Christmas Island Frigatebird.

 

Finella is currently doing a post-doc with the Conservation Science Research Group (UoN), in collaboration with the REC group, conducting research into the management of invasive rodents on Norfolk Island, particularly in relation to their effects on the island's fauna and flora species, many of which are threatened. This project will identify the significance of the reinvasion of rodents, determine whether control activities that are pulsed or continual yield better outcomes, investigate the roles of cats as predators of rodents and native wildlife, and assess how these issues translate to the biodiversity on the island more broadly.

Dr. Flossy Sperring

Post Doctoral Research Fellow & Collaborator

​​

Flossy undertook a PhD in the REC lab, working on the Critically Endangered Norfolk Island Morepork (Ninox novaeseelandiae undulata). She investigated habitat suitability and diet of the moreporks. She also established a long-term monitoring program involving citizen scientists and identified the most suitable source population for genetic rescue onto Norfolk Island. This research also provided new evidence to help resolve the taxonomy of Australian Boobooks, New Zealand Moreporks, and Tasmanian Moreporks. 

Flossy is now a Post-doctoral research fellow with Western Sydney University and Monash University, working on the Christmas Island Hawk-owl (Ninox natalis) and Goshawk (Tachyspiza fasciata natalis). The main objectives of her current research are to determine the status, health, diet, habitat requirements, and genetic diversity of the species, and develop a robust population monitoring design.

Lana Austin

PhD Candidate 

​

Lana loves birds.

After completing her Masters in Biology and Conservation at Macquarie University, she relocated to the Ecuadorian Amazon to get her hands on some tropical birds. One job led to the next (and one country to the next) and she realised “Hey, I could make a career out of this.” Since then, she has managed multiple bird research projects around the world including investigating the impacts of boat traffic on canal birds in Costa Rica, and the long-term monitoring of breeding behaviour in Scarlet Macaws in Peru. Always with a team of volunteers at her side, Lana is passionate about sharing her love of birds and nature with others in a fun and engaging way.

Lana is now a PhD student in the Persistence and Adaptation Lab and the Research Ecology Group. She now studies the Eastern Yellow Robin – a model species to investigate the role mitonuclear interactions and local environmental adaptation may play in the divergence of lineages. It's a project with a beautiful balance, where Lana's deep understanding of bird ecology in the field allows her to interpret observations with a genetic lens. 

In her free time, Lana enjoys indoor rock climbing, walking her cat Hamish, and café hopping in the suburbs

Tommy Landmann

PhD Candidate

​

Tommy has been obsessed with birds from a young age, ever since the first time he opened a field guide. Naturally this interest led him to become an avid birdwatcher, and into a career in avian conservation and ecology.

Tommy's PhD research is being undertaken on Adele Island off the coast of north-west Australia, where an eradication of the invasive Rattus exulans is being conducted in collaboration with the Department of Biodiversity, Conservation and Attractions. With this eradication program underpinning his PhD, Tommy will explore the connectivity of seabird colony islands across the Browse and Bonaparte Basins, and using population genetics and movement tracking technology, look into how these colonies recover after invasive species eradication.

Prior to starting his PhD, Tommy completed a BSc at Monash University with an Honours research project exploring the effect of fire management on riparian habitat in the central Kimberley. Over the years Tommy has gained extensive experience in remote fieldwork across Australia surveying for threatened birds, mammals, and reptiles. Tommy's particular research interests include threatened species conservation, movement ecology, and applied conservation ecology.
