We didn't record it unfortunately - but I would be happy to share the slides with you

Just updated it!

Could I please be added?

I remember that paper - I was actually speaking with Lucas about it recently, definitely have some ideas that could be fun to explore!

Key finding? Intraspecific variation in leaf traits plays a crucial role in preventing exposure to damaging temperatures. However, broader assessments across more species are needed to determine whether patterns emerge across phylogeny, functional types, or biomes.

Reach out if you’d like to chat!

To see how physiological and morphological acclimation to treatments affected thermoregulation, I then monitored leaf temperature & water use. Air temperature was ramped up from 18 to 38°C, and VPD was lowered from 4 to 1.5 kPa. This revealed some very complex responses - watch this space!

Temperature and vapour pressure deficit are highly correlated, complicating efforts to assess their impact on trait variation. I disentangled the effects of these variables on sapling growth, physiology, and leaf traits in a glasshouse experiment shorturl.at/kb87b @newphyt.bsky.social

Although intraspecific variation led to enhanced leaf cooling at warmer sites for some species - this was not always the case. Diverse species thermoregulation strategies were also observed when comparing lowland vs upland origin trees grown in a provenance trial for 2 years shorturl.at/sjdtV
