Excited to share our new paper on leaf scorching. 🔥Early leaf browning during heat and drought is often interpreted as premature leaf senescence - but it may reflect rapid heat damage. Separating these processes is essential. www.nature.com/articles/s41... @wslresearch.bsky.social
PhD position available: Predicting impacts of extreme heat on Australian forests The world is heating up and forests are starting to show the effects. Like maths? Love trees? Apply your skills to help understand and adapt vegetation to heat extremes! www.westernsydney.edu.au/schools/grs/...
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!

Need a Monday pick-me-up? Here's a throwback to 2022, when our field ecology program director Susan Bush had an extraordinary encounter with a huge band of coatimundis while working at our field site in Wet Beaver Creek, AZ How many can you spot?? #coati #ecology #fieldwork #arizona
Mapping the roots of saguaros at Saguaro NP. The DBG is partnering with SNP and the U of Wyoming to map the roots of saguaros. Knowing the distribution of saguaro roots reveals how sensitive they are to droughts, and to what extent these iconic plants engineer the water cycle of desert ecosystems.

David Lynch gave us the language we needed to better articulate the indescribable strangeness of our shared reality. “Lynchian” is so overused because it’s a viscerally understandable word without any known synonyms. I can’t imagine a more beautiful artistic legacy than that.
