We all love trees. But lianas are beautiful too! Cross-sections reveal the pattern of xylem tubes, reflecting the stem space dedicated to transporting water skywards and phylogenetic variation in a liana community.

Extreme heat is fast becoming one of the biggest threats to global food systems. Our new piece in The Conversation looks at how intense heatwaves put crops and native species at risk — and what we can actually do about it. 🔗 theconversation.com/intense-heat...

Australia’s trees are dying faster — not from fire, but from the stress of a warming, drying climate, weakening their role as vital carbon sinks. 🔗 theconversation.com/yes-forest-t... @bmedlyn.bsky.social @westernsydneyu.bsky.social @profchoat.bsky.social

Drought is often omitted from IUCN Red Listing assessments as it is difficult to quantify. But our study has found that >95% of threatened species will be exposed to longer and more frequent droughts! www.sciencedirect.com/science/arti...

Drought and insects have killed an unprecedented number of Oregon’s Douglas fir trees during the last decade, costing billions in timber value, damaging infrastructure and ramping up wildfire danger. What is Douglas fir dieback? Where is it happening? What is being done? tinyurl.com/5n9amvx6

Sometimes I think about how from 1935-1975ish, Bell Labs produced an insane amount of revolutionary science and technology, including 11 Nobel Prizes, the transistor, UNIX, C, the laser, the solar cell, information theory, etc. The secret? Provide scientists with ample, steady, no-strings funding.

🌿🔥How heat and VPD shape tree survival? We tested how acclimation to high temperature & VPD impacts drought mortality. While heat speeds up death via leaf area expansion, VPD acclimation slows it down by enhancing stomatal control - balancing mortality timing. doi.org/10.1111/PCE....

Are we seeing the last of the stringybarks in the Mount Lofty Ranges? Large areas of remnant trees now dying in the ranges & on Fleurieu Peninsula in SA 😳 This example in Belair Nat. Park.
