Associate Professor Duanne White – ‘Antarctic ice shelves?’
2025-11-27 12:30 - 13:30 (Australia/Sydney) | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
What lies beneath Antarctic ice shelves? Duanne, from University of Canberra, will show field studies of how warm ocean currents, past and present, are melting the weak underbelly of the ice sheet in the Denman Glacier region.
Associate Professor Duanne White is a quantitative geomorphologist and geochemist, at the University of Canberra, interested in catchment and Earth Systems. This involves understanding the links between landscape, climate and critters, and how these have changed during the Quaternary period – i.e. the last couple of million years. This interest has taken him across Australia and on several trips to Antarctica, the Arctic and Sub-Antarctic Islands and beyond.

Craig Moritz – Discovering diversity across Australia’s tropics
2026-02-19 12:30 - 13:30 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
Craig Moritz, from the ANU, will talk about the true species diversity of vertebrates in the monsoonal tropics, and how this matters for science, conservation, and ecological management.
You might think that we know all about Australia’s vertebrate species – what they are and where they occur. However, ongoing surveys and genetic analyses tell a different story – we have massively underestimated true species diversity across the vast monsoonal tropics. This matters for science, conservation, and informing ecological management, especially in areas owned and managed by our First Peoples.
Craig Moritz is an evolutionary biologist who likes nothing more than traveling to remote areas to survey animal diversity and interact with landholders. He is a Professor at ANU and a Fellow of the Australian Academy of Science.

Chris Mobbs – Bragg Street Park, Hackett: Increasing biodiversity through water harvesting
2026-02-26 08:00 - 17:00 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
Chris Mobbs, Convenor Bragg Street Park Volunteers, describes solving a drainage problem and creating an urban oasis with a great increase in the diversity of native plants.
Residents near a neighbourhood park in Hackett came together to solve a drainage problem. They ended up creating an urban oasis. Their project was funded with a Nature in the City grant in 2021.
It is now 4 years since the swales were built, and they have been very successful in preventing minor flooding in gardens downhill from the park. There have also been great results in increasing the diversity of native plants in the park – many have been planted by the park volunteers, but many self-seeding eucalypts have grown up in the swales.
Our volunteer group was very pleased when the ACT Government used our park as a case study in the recently released Stormwater Management for Community Groups guidelines: https://www.act.gov.au/open/stormwater-management-for-community-groups.
I am pleased that the photo on the cover of these guidelines is one of the swales in our park, and there are more details on page 25. As well as the swales successfully capturing water and the great growth of native plants, we had 5 species of frogs move into the park in the spring of 2023 and 2024. And in spring 2023, a lovely bearded dragon moved into the park. And last spring, we counted 4 smaller ones – we think these may have been offspring from the first dragon.
Chris Mobbs has a Bachelor’s in Applied Science (1976) from the then Canberra College of Advanced Education (now Uni of Canberra). My first job was an interpretation ranger (1976-84) with the then Conservation and Agriculture department (later renamed the ACT Parks and Conservation Service). My activities included taking people on day and night-time walks through Canberra’s nature reserves like Tidbinbilla, Black Mt, Mt Taylor, Mt Ainslie, and Majura, and preparing brochures about Canberra’s wildlife. In 1983-84, I co-hosted, with Mike Braysher, the Wildlife Biologist, a 30-minute segment called Canberra Bush and Fauna once every 3 weeks on ABC local radio morning program (then known as ABC 2CN but today is ABC 666). From 1984-96, I worked in the Australian National Parks and Wildlife Service Education Section and then helped manage programs including Save the Bush, One Billion Trees, and the Waterwatch program. From 2000-07, I worked in the Chemical management program of the Federal Environment department before moving to energy efficiency programs until I retired in early 2017.

Leo Joseph '12 Birds, 3 Books, 5 Cities, and 3 Continents: An Ornithological Life Not Yet Finished’
2026-04-23 12:30 - 13:30 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
Leo, recently retired from CSIRO, appreciates how pivotal it was for him to see certain species of bird in the wild in Australia and South America and the happy pursuit of a career studying evolution of birds, especially in these countries.
Abstract
Triggered by glimpses in childhood of Adelaide Rosellas and further ignited by experiences of almost inhaling books on Australian birds, seeing with awe museum collections of birds and not to mention a lifetime of camaraderie with like-minded friends and colleagues, I will look back (and ahead) on a life studying the evolution of Australian birds (with a little more yet to come). Having recently retired from CSIRO where I was Director of the Australian National Wildlife Collection from 2005-2025, I can look back and appreciate how pivotal it was for me to see certain species of birds in the wild, and to travel across Australian and South American landscapes, while all the while avidly absorbing the literature of ornithology and working with many colleagues. The result was perhaps dogged yet always happy pursuit of a career studying evolution of birds especially across Australia and South America.
Biography
Leo joined CSIRO as Director of the Australian National Wildlife Collection in November 2005. Originally from Adelaide, he developed an early but lifelong interest in the evolution of birds and especially in a museum collections environment, one that has always guided his work. He did undergraduate and Honours degrees at the University of Adelaide in 1977-79 and 1981, respectively. Then he worked in Australia and travelled in South America until doing a PhD at the University of Queensland from 1989-1994. For his thesis, he investigated the history of habitat diversity in eastern Australian rainforest birds. Then, from 1994-97, he held a Visiting Professorship in the Laboratorio De Evolución, Faculdad De Ciencias, Montevideo, Uruguay where he worked on shorebird evolution and the evolution of bird migration. His interest in integrating ecological diversity and evolution was by then well-established. In 1997 he took up a position in the Department of Ornithology at the then Academy of Natural Sciences of Philadelphia, in the USA. From 2003, he was Chair of the Department but returned to Australia in 2005. At CSIRO, he developed an extensive network of collaborators including fellow researchers in Australia, Europe and North America, postdoctoral researchers, PhD students and Honours students. He has amassed a body of work on the phylogeography and more recent evolutionary history of Australo-Papuan birds. He was awarded the D. L. Serventy medal for publication in Australian ornithology in 2018. In 2020 he was elected as a Fellow of the American Ornithological Societies. Despite all that, he remains a birdwatcher at heart and plans to do a lot more birdwatching in the coming years.

Kim Pullen ‘More treasures–insects in fens and bogs’ [NEW VENUE: Crosbie Morrison Bldg]
2026-05-14 12:30 - 13:30 | Crosbie Morrison Building, ANBG, Clunies Ross Street, Acton, Australian Capital Territory, 2601, Australia
Kim will discuss bogs and fens as an insect habitat, the variety of ecological niches that insects occupy and some threats to the fauna. She will give some local examples of the fauna of this habitat.
NEW VENUE: Crosbie Morrison Bldg
Biography
Kim grew up in Canberra and inherited an interest in nature, and particularly insects, from his father who was a professional botanist (and a boyhood butterfly and beetle collector). On leaving school he worked first at the ANU, and later at CSIRO, assisting with research in grasshopper genetics, pheromone-based control of insect pests, and insect-based biological control of imported weeds. Kim then spent six years in Mexico collecting and evaluating weed biocontrol agents for exportation to Australia – as well as teaching English – before returning to Canberra with a family. He eventually came back to CSIRO to assist with faunal studies in South Australian mallee and subsequently on Murray River floodplains, and prepare a taxonomic inventory of Australian weevils, among other projects.
After retirement, he took up a CSIRO Honorary Fellowship, allowing access to the Australian National Insect Collection. This helped Kim carry out a long-running ambition to compile a catalogue of the insects of the ACT. He now enjoys identifying insects for the general public on citizen science platforms and on social media (when their grandchildren allow it).

We wonder, we discover and we take action. We’re using the 50 000 native bee specimens in our collections to discover what native bee species exist and where they live. This will help people take action to preserve the pollination benefits they provide to native plants and make use of their pollination services for agricultural plants.
Andrea will share some of the stories from the new popular science book Wild Collections. Learn about sharks living in sponges, orchids flowering underground, Spotted Handfish guarding their eggs, weevils rolling dung just like scarabs do, Giant Kelp towering in Tasmania’s seas, quirky tales of worm bums, Darkling beetles undertaking a decathlon, the curlicues of shark’s eggs and much more.

Charlie Blumer and Jon Darvill ‘Flower power and no bad bees: Getting the big picture on pollinators in the ACT’
2026-06-04 12:30 - 13:30 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
Charlie Blumer and Jon Darvill explore the identities and ecology of some of the 200-odd native bees and other pollinators in the ACT. They identify why they matter, the threats to them, and how we can help them.
Abstract
Charlie Blumer and Jon Darvill explore the identities and ecology of some of the 200-odd native bees and other pollinators in the ACT. They identify why they matter, the threats to them, and how we can help them. We also balance this against the presence of European honey bees, essential for the pollination of most of our food crops, and the likely impact of the Varroa mite as it spreads across the ACT.
Biography
Charlie Blumer was trained in zoology and epidemiology, before working as a public servant in the health area. Now retired, he keeps bees and enjoys being present in his own little ecosystem, watching it all happen. However, he does also get out, and out of his comfort zone, to spread the word in various fora.
Jon Darvill is a natural beekeeper with 11 years’ experience of keeping honey bees in Warre and Kenyan top bar hives. These lend themselves to a bee-friendly approach to beekeeping. He is also a member of the Canberra Region Beekeepers Association, serving on the committee and teaching in the club’s beekeeping courses.

Dr Gina Newton ‘River Murray—Darling to Sea: listing Australia’s first river system as threatened’
2026-07-02 12:30 - 13:30 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
Gina will discuss the first ever listing of an Australian river system, the River Murray—Darling to Sea, as a threatened ecosystem under national environmental law, including: what it is, why it’s threatened, how it was assessed, the challenges involved, the benefits of listing, and priority recovery actions. (Photo: Ben Good)
Abstract

The River Murray, downstream of the Darling River, and associated aquatic and floodplain systems (known as the River Murray—Darling to Sea) was listed nationally as a Critically Endangered ecological community (aka ecosystem) in January this year.
This listing represents a first for Australia, although its journey was challenging—scientifically, socially, and policy-wise. A similar attempt in 2013 saw it being the first disallowed entity in the history of the Environment Protection and Biodiversity Conservation Act 1999.
The decades long decline of the River Murray—Darling to Sea is due to many compounding threats, with water extraction, invasive species, and climate change impacts, prominent. The listing, along with efforts under the Basin Plan, represents a positive and hopeful way forward for the Mighty Murray and its dependent biodiversity.
Biography
Gina is a marine biologist, zoologist and science communicator. She has worked for several decades at the science-policy interface with the Australian Government, in a range of environmental areas, including fisheries, state of the environment reporting, climate change science, and Murray-Darling Basin ecology. A career highlight has been undertaking assessments for listing several world-first, landscape-scale aquatic threatened ecosystems under Australian environmental law.

Dr Phillip Kodela ‘Wattle in Your Pocket, the Bank-notable Wattles – science behind the Next Generation Banknotes of Australia’
2026-07-16 12:30 - 13:30 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
Philip, from the Australian Biological Resources Study, advised on the design and five species of Acacia to be used in the Next Generation Banknotes. He will tell us why there was a need for the new banknotes, why these wattle species, and some of the technical issues and challenges with the project.
Abstract
Acacia is the largest genus of vascular plants in Australia with over 1000 species. They are a prominent part of the Australian flora, growing in a wide range of plant communities and habitats, from coastal to subalpine and tropical to arid. Wattles are readily recognised in the landscape by their array of mostly yellow-hued flowers, and they feature through much of our culture. Acacia is represented in the national floral emblem (Golden Wattle Acacia pycnantha), the Commonwealth Coat of Arms, Order of Australia medals, currency, stamps, literature, the arts, crafts and design. Over tens of thousands of years, indigenous cultures developed a detailed knowledge about acacias and their wide range of uses, from wooden implements to food and medicine. In more recent times, acacias have been used for their wood, tannin and oil; as stock fodder, cut flowers and a source of food; and in horticulture (countless ornaments in parks, gardens and landscaping), land rehabilitation and soil stabilisation. It is appropriate therefore that the iconic wattle features on our latest Australian banknotes. As a subject matter expert Phillip advised the Reserve Bank of Australia on the five species and designs used in the Next Generation Banknotes program which began c.2015. Phillip will talk about the species and their morphological features represented on each of the banknotes. He will also address why there was a need for the new banknotes, why these wattle species, and some of the technical issues and challenges with the project.

Professor Marcel Cardillo 'Grevillea/Hakea: the story of a remarkable evolutionary radiation'
2026-08-20 12:30 - 13:30 | ANBG Theatrette, Clunies Ross Street Acton ACT 2601, Canberra, ACT, 2601, Australia
The genera Grevillea and Hakea form one of Australia’s most spectacular and successful evolutionary radiations, with at least 650 species distributed almost ubiquitously across the continent. Our team at ANU have spent over a decade piecing together the story of this remarkable group: its origins and evolutionary history, its current patterns of diversity, and its prospects for the future under rapid environmental change. I will talk about the story of Grevillea/Hakea , as far we now know it, and what this group can tell us more generally about how climatic and biogeographic changes over tens of millions of years have shaped the Australian flora as we see it today.

Marcel Cardillo is a professor with the Macroevolution and Macroecology Group, in the Research School of Biology, Australian National University. His work focuses on computational analysis of large biodiversity datasets and aims to understand the evolutionary history and present-day conservation of biodiversity.
