Education
Paton earned a Bachelor of Science degree from the University of Adelaide in 1975, and completed his Ph.D. at Monash University in 1980.

Career
Paton began his academic career at the University of California as a Research Biologist in 1979. In 1981, he was awarded a Queen Elizabeth II Fellowship and spent two years conducting research at the Australian Museum before becoming a Senior Teaching Fellow in the Department of Zoology at the University of Adelaide from 1983 until 1986. He then held various research appointments in the Department of Zoology at the University of Adelaide between 1987 and 1996. Subsequently, he joined the Department of Environmental Biology at University of Adelaide as a Lecturer in 1997, and was appointed a Senior Lecturer in 2000. Having served at that position till 2003, he held an appointment as an associate professor in the School of Earth and Environmental Science there from 2003 till 2019, when he retired. Since 2020, he has been serving as an Adjunct Associate Professor of the School of Biological Sciences in the Faculty of Sciences, Engineering, and Technology at the University of Adelaide.

He managed the Flinders-Baudin (Field) Research Centre on Kangaroo Island for the University of Adelaide from 2000, until the facility was destroyed by wildfire in January 2020.

Paton was a co-founder of the non-profit organization, Arid Recovery, which works for the sustainable restoration of arid ecosystems and the conservation of threatened species in Australia, and served as a board member from 2009 to 2013. He also co-founded Bio-R, and has been directing restoration programs, and revegetation works in Southern Australia since 2008.

Research
Paton's research works have received numerous awards, such as the D.L. Seventy Medal, Member of the Order of Australia, and South Australian Premier's Science Excellence Award. His research spans the fields of ecology, conservation biology, ecosystem restoration, and conservation, with a particular focus on understanding, and managing the natural systems of South Australia.

Animal-plant interactions
Paton's early research provided the initial evidence that birds, particularly honeyeaters, are efficient pollinators of many of the dominant plant genera in temperate Australia. From the 1970s to the 1990s, his research included detailed field observations combined with small-scale experimental treatments that focused on testing and quantifying various aspects of plant-animal interactions. He investigated the ecology and behavior of the New Holland Honeyeater documenting their diet, breeding schedules, territoriality, population structure and competitive interactions with other honeyeaters. His research also demonstrated how the ecology of many honeyeaters depends on carbohydrates (sugars) with a chemical structure similar to nectar, such as manna, honeydew, and lerp.

Paton's research on the interactions between honeybees and Australian biota highlighted that, while honeybees were thought to be beneficial for the Australian environment because they may aid in the pollination of native plants, they can displace native pollinators and not contribute to pollination. He indicated how the interactions between honeybees, and biota are rather complex, both spatially and temporally. Later, he and Thomas Celebrezze investigated the effect of introducing honeybees on the pollination of bird-adapted Australian plants, reporting that, while honeybees were significantly more frequent visitors to flowers, native birds played an important role in maximizing fruit set.

Management of Australia’s natural environment
Paton has contributed to the study and management of Australia's natural environment for decades, and is known for his research work on Kangaroo Island and the Coorong, with a particular emphasis on managing and protecting ecosystems.

Paton established and has maintained long-term monitoring initiatives since the 1990s in order to record trends, educate the public, and support local efforts intended to deliver quantifiable biodiversity outcomes. This includes monitoring woodland birds and their habitats in the Mt Lofty region, and biota using mallee-heaths in South Australia. One of the significant long-term programs includes monitoring waterbirds in the Coorong and a key aquatic plant Ruppia tuberosa in the Coorong. He highlighted the progressive loss of this plant species, which is considered critical to the Coorong's ecology, i.e., as a food source for waterbirds and a habitat for invertebrates and fish in the Coorong. The findings also emphasized that declining flows to the Murray Mouth in spring was a crucial issue that must be addressed since the reduced flows restrict the time available for these plants to establish, grow, and reproduce. As part of the Coorong monitoring program, recent investigations showed how filamentous green algae affected seed production of Ruppia tuberosa as well as access to food for waterbirds.

Habitat restoration and re-vegetation
Paton's long-term research and monitoring have highlighted the ongoing declines of woodland birds in the Mt. Lofty region of South Australia and the need for large-scale habitat re-establishment to prevent these declines. This has resulted in an increased emphasis on how to re-establish self-sustaining and resilient woodland habitats on land cleared for agriculture at landscape scales to help meet the needs of declining species. These revegetation projects are largely managed through Bio-R and include restoring native vegetation to Cygnet Park on Kangaroo Island and to Frahns Farm, near Monarto, South Australia.
