I'm looking for a postdoc to work on an Australian Research Council Laureate Project on climate change responses, applying a Julia implementation of the NicheMapR package. The work could go in control theory, DEB theory or population process directions unimelb.wd105.myworkdayjobs.com/UoM_External...

Help put pressure on the govt to fight the curse of buffel by declaring it a weed of national significance. Buffel is transforming our beautiful desert ecosystems through its dominance and alteration of fire regimes. It is arguably our worst invasive species invasives.org.au/how-to-help/...

📢 Big news from the Biodiversity Heritage Library: The Smithsonian will no longer host BHL’s central operations from Jan 2026. After 20 years, we’re entering a new chapter – seeking new funding and support to sustain our global staff and infrastructure. Please share. 🌱 #ILoveBHL #OpenAccess

Biodiversity Heritage Library@biodivlibrary.bsky.social

Change is in the air for BHL! In 2026, BHL hosting will transition away from the Smithsonian, opening doors to reimagine our future. Rest assured, our 63 million pages of biodiversity knowledge remain secure and accessible. Learn what's next for BHL ➡️

This is a Len Beadell marker I photographed last weekend on the Gunbarrel Hwy in South Australia, surrounded by an ecological and social disaster called Buffel Grass. Anangu call it tjanpi mamu which means "devil grass" in Pitjantjatjara. It's steadily eroding the flora and fauna of our deserts.

This is a Len Beadell marker I photographed last weekend on the Gunbarrel Hwy in South Australia, surrounded by an ecological and social disaster called Buffel Grass. Anangu call it tjanpi mamu which means "devil grass" in Pitjantjatjara. It's steadily eroding the flora and fauna of our deserts.

I was with John Read who has watched it spread over the 25 years of regular visits. It's spreading by wind, humans, cars and mammals. It's killing river red gums, figs, mulga woodlands, and smothering flower-filled native grasslands and spinifex-covered sand dunes and plains.

It changes fire regimes to be more intense and burns the country to a monoculture. It is the light green in the photo, spreading up into the hills replacing Triodia. Efforts to control it by spraying or weeding are now like trying to hold back the tide and the only real hope is biological control.

A great summary by @nicholaswu.bsky.social on a paper applying #NicheMapR to model climate change impacts on heat stress in frogs globally, led by @patricepottier.bsky.social. Note how different the +2 and +4 warming scenarios. Climate warming impacts on biology are very nonlinear. #UniMelb #ARC

New paper in @nature.com led by @patricepottier.bsky.social! We demonstrated global vulnerability of amphibians to warming, threatening 10% of >5,000 species examined. How did we do it? See thread🧵 Paper: www.nature.com/articles/s41...

The parthenogenetic species meets the sexual ones (from which it evolved by hybridisation) on the outskirts of Kalgoorlie where this hybrid mating happens naturally. They form “hybrid zones” where triploid offspring have very low fitness meaning they can’t coexist.

I’ve collected males from nearby sexual populations and set them up with the parthenogenetic females (who haven’t had sex for a couple of hundred thousand years). What should happen is that the males’ sperm fertilises the cloned eggs so that their offspring will have three sets of chromosomes.

The late Eric Pianka made thousands of observations of desert lizard body temperature and activity.

This week I assisted with the annual pitfall trapping at Secret Rocks on the Eyre Peninsula. This beautiful place is a living arc for so many species of endangered wildlife, including Numbats, Malleefowl, Red-tailed Phascogales and the Sandhill Dunnart. 1/2

I like the last paper I published- In it collaborators and I test a classic hypothesis in ecology for the first time (that we are aware of) in plants. The take-home message is plants that like temperature variability may “win” in future climates. www.journals.uchicago.edu/doi/full/10....
