The cuscus is a small possum, a ball of fluff the size of a housecat, found in northern Australia, Papua New Guinea, and various islands across Southeast Asia. But this wasn’t always the case – cuscus were brought to the islands by people thousands of years ago and, by studying the spread of this animal, researchers are hoping to learn more about the connections and trade routes of past people. 

In this episode, we chat with archaeologist and palaeobiologist Dr Shimona Kealy (@ShimonaKealy) from the Australian National University’s College of Asia and the Pacific who is using DNA sequencing technology to analyse modern and historical genetic samples to figure out when and where cuscus was introduced across the region.

Pollen isn’t just the stuff that gets up your nose during the hayfever season. Pollen, an integral part of plant reproduction, also serves as a time capsule of past environments; by analysing these microscopic marvels, researchers can determine what plants were present in a landscape thousands to millions of years ago. 

In this episode, Matthew Adeleye (@matt_adeleye) from the Australian National University helps us understand the journey of pollen grains – from a plant to being trapped in the mud at the bottom of lakes to the microscope slides examined by palynologists (people who study pollen). By counting and measuring these grains, palynologists like Matthew can discover invaluable information about past landscapes and vegetation.

The rainforest trees of the Surrey Hills region of northwest Tasmania feel immensely ancient but they are actually less than 180 years old. Once upon a time, this region was more of an open-woodland than the dense, wet rainforest we see there today, and the land was actively managed and maintained by Aboriginal Australians for millenia.

In this episode Associate Professor Michael-Shawn Fletcher (@theotheroad) explains the use of fire by Indigenous people and the impact that it had on shaping the natural environment.

In this episode, we talk to Dr Ariana Lambrides about her work pulling together the data on fish remains excavated from archaeological sites all along the Queensland coast since the 1950s. This meta-analysis provides some useful information about diverse fish exploitation along the coast by Indigenous people throughout the Holocene (last ~11,700 years) but highlights the large gaps in data for these regions.

Do you know what it takes to put together a broken thousand-year-old pot scattered among 20,000 other pieces? This is just another day’s work for Holly Jones-Amin, Senior Objects and Archaeological Conservator at the Grimwade Centre for Cultural Materials Conservation at the University of Melbourne.

In this episode, Holly takes us through the careful reconstruction of the Ruisasi 1 incised pot, excavated from an archaeological site in Caution Bay, Papua New Guinea.

In the Bass Strait Islands, the removal and eradication of Wedge-tailed Eagles, quolls and Tasmanian devils and the introduction of livestock and invasive predators like cats have brought about drastic declines in native wood bird populations. Could the reintroduction of these native predators help to rebalance this ecosystem? This week we talk to Matthew Fielding about roadkill, ravens, currawongs and the pros and cons of trophic rewilding, a form of ecosystem management where top-level predators are reintroduced, aiming to restore the natural structure of food webs.
