New paper by fellow PhD student Mark Clifton @ the Plant Reproductive Ecology & Conservation Genomics Lab! This study investigates polyploidy and hybridisation in endangered, clonal Callistemon species from Victoria, Aus. doi.org/10.1071/BT25... 🌏 🌿 🧪

Polyploidy arises independently of hybrid status in clonal narrow-range endemic Callistemon from East Gippsland, Victoria

Three threatened narrow-range Callistemon species from East Gippsland are highly clonal, but differ in their evolutionary origins. Previous genomic studies

1/ Given recent attacks on Camp Sovereignty & the fact that a little rich kid racist is assembling the troops agen this Sunday, it'd neat if lots of people attended this I reckon. 2–8pm Camp Sovereignty · Naarm Free concert + delicious food

Camp Sovereignty presents Rock Against Racism.

This article is excellent. It speaks volumes about how governments take so many in the environmental and conservation sectors and communities for granted theconversation.com/australia-ha.... As H5N1 begins to spread and devastate Australian wildlife the dire consequences of this are evident.

Australia has long relied on volunteers and wildlife carers. As bird flu spreads, they will need support

Volunteers have been a mainstay of conservation in Australia. As bird flu spreads, they must be supported – and kept safe.

Now in summer, we can confirm that a large part of the beech (Fagus sylvatica) forests that burned in low‑intensity understory fires have died. This constitutes a clear case of a low‑intensity, high‑severity fire (I had expected bsky.app/profile/jgpa...) 🧪🌍🔥🌳🍁🪴 wildfires Picos de Europa, N Spain

Another novel disturbance: fire affecting beech (Fagus sylvatica) forests. It burned at low intensity (surface fire), but it is likely to have high-severity effects. Barniedo fire 8/2025, Riaño, León, Spain 🧪🌍🔥🌳🍁🪴🌱 wildfire

Burned landscape: The shrublands (left) burned at high intensity but became low intensity (surface fire) when reaching the beech forest (right) due to its lower flammability.

I am hiring! My former postdocs have all gone on to great ongoing roles, so I am now looking for 2 new postdocs in dynamic vegetation modelling: Modelling vegetation-fire interactions in Australia Modelling Australian vegetation distributions Details linked below - please share!

Its been a while! March was extremely hectic between working on submitting a manuscript for review, giving talks and general Masters work. Have a photo of some Grevillea pollen from the archives (Grevillea jephcottii, taken in 2022). The centre pollen grain is showing pollen tube growth!

A microscopy photo taken under brightfield of several Grevillea pollen. The pollen is fat and triangular, with each tip bearing a rounded protrusion. A pollen grain in the centre has a gelatenous-looking tube extending out of one of the bulbus tips. This is a pollen tube.

After decades of environmental and biodiversity failure, the idea of relying on "nature markets" is just the latest sick joke from the neoliberals who brought us the destructive privatization of public services. #auspol

In 2023, then Enviro Minister Plibersek said the heart of EPBC reforms—National Environmental Standards—would set "legally enforceable requirement for decision making – that approval decisions deliver a positive net outcome for nature" @euanritchie.bsky.social & I examine the reversal of promises

Probably a reach here but I'm looking for someone (early career maybe) who would be willing to mentor me as I navigate the post-PhD life. I feel lost on a lot of things and would be grateful to bounce ideas and experiences with someone who's been through a couple of years post-PhD. 😭

I've been thinking about how Starmer and the Labour Together purge of the left in the party has done the opposite of what they intended. Instead of crushing the left they have liberated it from the shackles of the Labour Party. Fingers crossed for Hannah Spencer in Manchester 🤞

You can smell the Labour Governments panic. They're trying their hardest to discredit the new poll because it tells everyone that the alternative has well and truly arrived. Gorton & Denton is the Green Party Vs Reform.

Labour to come third in key byelection

I am simultaneously excited that there is so much to learn about the natural world and also frustrated that I don't have all the answers now. Two galls I'm seeing and here and there is nothing about them in the literature. Eremophila leaf galls and these spongy Banksia galls demand answers

Juicy purple green leaf galls in Eremophila deserti near Melbourne, AustraliaThese weird brown spongy galls appear to affect the follicles of Banksia marginata in western Victoria, Australia.

Here's some impressive Mesostoa kerri galls on silver Banksia. Because we can roughly date Banksia with node counts we can tell that this Banksia has been infested for several years and because Banksia retain cones for years we also know this individual has not successfully produced any fruit.

Large swollen stem galls. These are usually packed will larvae of this host specific waspHere are several years of galls. They form on the newest growth and Banksia can be dated with node counts so we get a good idea of how long they've had this colony of gall waspsThese are previous years galls that are filled with exit holes
