Most major theories in ecology assume some sort of equilibrium, but only ~half of empirical tests acknowledge it & even fewer observed it in their system. Does this matter? How did the idea become so pervasive in ecology anyway? Find out in our new paper! onlinelibrary.wiley.com/doi/10.1111/...
The Equilibrium Conundrum
Although an assumption of equilibrium dynamics underlies most ecological theory, the evidence for this dynamic in nature and in empirical studies is scarce. This creates an unfortunate disconnect bet...

Monday was spent scouting for new field sites when we stumbled upon this beauty 😍
Dipodium roseum - a saprophytic orchid that does not produce chlorophyll but rather relies on carbon from decaying matter near eucalypt trees.

In the first half of 2025, renewables became the biggest source of global electricity for the first time, as wind & solar growth exceeded global demand growth

Shocking that it's China & India leading - EU & USA have fossil power growing

Loyalty and nutrient trade… University of Western Australia researchers show how plants and fungi keep their partnerships alive—even in the face of cheating 🍃 ❤️ 🍄

A simple plant–mycorrhizal fungal resource trade co‐evolution model explains mutualism stability, extinction and transitory parasitism via fitness feedback
The mutualism between mycorrhizal fungi and plants has persisted for over 400 million years, despite the mutualism paradox predicting that mutualisms should be evolutionarily unstable due to the fit.....

The world needs more of Jane Goodalls and alike.
Dr Goodall was such an inspiration. I was fortunate enough to see her speak and meet at Tulane University speaking tour in 2016-2017, she came across so humble and gentle yet firm in her opinions and of course, very wise.
RIP, legend 💫
We’re heartbroken to learn that Dr Jane Goodall has passed away, aged 91.

Dr Goodall was one of the true conservation giants of our time. Let’s honour her legacy by choosing to make a difference in the world - by protecting it.

Thank you, Jane, for everything you did for our planet. 💚

Started my Friday with this lovely E-Mail:
"Well I also happened to watch your interview on YouTube today and I must say you are truly an amazing person both inspiring and insightful." ☺️
So, I went and checked the above-mentioned interview, a talk actually, and it has 1.1 k views on YouTube! 🤯

Love getting emails from my students:
"Dear Professor Birnbaum,
My name's X and I've just completed the course REN3302 - Sustainable Resource Use with you this trimester. I loved the course and found it very engaging [...]."

Also, Professor Birnbaum has a good ring to it 🤓

Mini marsupial bounces back from the brink!

Once listed as Endangered, the crest-tailed mulgara expanded its range by more than 48,000 km² between 2015 and 2021, lifting its status to Least Concern. Biocontrol contributed to the heartwarming bounce-back.
