The Bogong Moth Population Puzzle

An iconic species of the Australian Alps, the mountain pygmy possum (Burramys parvus) is found in a unique and fragile habitat that is highly sensitive to environmental change. Habitat conservation and genetic rescue-based conservation efforts have allowed some populations to rebound, but the possum is facing new threats, and the species remains Critically Endangered on the IUCN Red List of Threatened Species. The Bogong moth, a key food source in the mountain pygmy possum diet, has declined in recent years. Efforts to understand Bogong moth biology are underway.

The Mysterious World of Fungi

The kingdom of fungi is an important, though often underappreciated, family of organisms which include yeasts, rusts, moulds, smuts, mildews, stinkhorns and mushrooms. Of the vast range of living things on the Earth, fungi make up an impressive 9% of all biodiversity. The immensity of the mighty fungi kingdom and the diversity of fungal organisms and functions means we can’t fit everything into a brief exploration; however, mycologist Dr Sapphire McMullan-Fisher gave us some comprehensive insights to the mysterious world of fungi to share.

The Universe and Its Dark Materials

Dark energy makes up approximately 68% of the Universe and dark matter makes up another 27%. Despite their dominance in the Universe, we are still not sure what they actually are. Alan Duffy investigates how dark matter helps galaxies form and keeps them intact. He uses supercomputers to simulate this process. But the more we learn about the visible parts of the Universe, the bigger the gap becomes between what we predict about the unknown and what we see. He and other astrophysicists are constantly under pressure to gain a better understanding and provide explanations of how dark matter and dark energy are present all around us.

Top Climate Scientist Awarded the Royal Society of Victoria’s Research Medal

In his leadership of CLEx, Professor Andy Pitman convenes scientists from institutions across the nation. Andy has conducted extensive climate science research on land surface models, looking at the impact of terrestrial changes in Australia’s climate and the moderation of climate extremes, producing 99 papers of exceptional quality and impact in the ten years up to 2018. He has led two ARC Centres of Excellence with extensive participation in key international, national and government committees. He is an outstanding scientist, and a significant science leader.

Deterring Possums with Pyrethrum

After noticing the presence of both brush-tailed and ring-tailed possums foraging around and damaging the plants in her backyard, zoologist and keen gardener Professor Lynne Selwood came up with the idea to develop a substance that could preserve and protect her beloved plants from browsers, i.e., animal species that use trees for their habitat and something that was readily accessible for all to use. During the first five years, she conducted a series of independent experiments, choosing particular plants from her garden that were inedible to possums.
