La recherche prend de la hauteur avec l'installation d'une passerelle dans la canopée de la forêt expérimentale de @univbordeaux.bsky.social 🌳

Cet aménagement facilitera l'accès aux branches, permettant de compléter les suivis au sol pour étudier la réponse des arbres au changement climatique. 🍃

Weak global trade‐off between frost and drought resistance in trees Drought and frost stresses play important roles in determining species distributions, especially at range margins. Understanding how stress resistance traits interact to determine vulnerability to c...

🌳We found a weak trade-off: drought resistant trees tend to be less frost-hardy & vice versa 🌡️🔥❄️
🌲💪 Conifers are generally tougher than angiosperms🌺
🧐No "costs" related to fast-slow economics spectrum 🍃🌱

Photosynthetic Heat Tolerance Partially Acclimates to Growth Temperature in Tropical Montane Tree Species Climate warming poses a risk to tropical montane trees by narrowing their thermal safety margins, particularly in species with traits that lead to higher leaf temperatures. While photosynthetic heat ...

Our new study from RWANDA TREE shows that:
Species with big leaves & low stomatal conductance tolerate more heat, but with tighter safety margins.
Heat tolerance acclimates,but partially:+0.31°C per +1°C Tgrowth
Leaf temperature matters more than heat tolerance for survival. doi.org/10.1111/pce....

Seed Production and 22 Years of Climatic Changes in an Everwet Neotropical Forest This study examined how five climatic variables influence seed production at the community level in an everwet Amazonian forest over 22 years. We found that rising nighttime temperatures and decreasi....

I have commented that recent paper on LinkedIn. It’s the most important article published so far showing the effect of climate change in the last two decades, especially increase temperature, on fruit and seed crops in an Amazonian rainforest. doi.org/10.1111/ele....

🌿🔥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....

Cool viewpoint on the impact of extreme temperatures on cell death. Perhaps some ecophysiology is required to articulate whole-plant observations and cellular mechanisms 🌿

Minimum leaf conductance during drought: unravelling its variability and impact on plant survival Leaf water loss after stomatal closure is key to understanding the effects of prolonged drought on vegetation.

Are tropical forests in the Americas changing as adaptation to ongoing climate change? Yes, they are!
Are these changes enough to track their suitable climate?
Not quite! Check out our paper in @science.org www.science.org/doi/10.1126/... to see more of what our network has been working on!

Agreed. Doesn't elevate the debate to the level it deserved. Interesting content, way above my understanding, but in a rather cheap style

Not my field but it's often the first topic people ask me about when talking about trees and I'm happy to share what I understood about the state of the art: not as exciting for most, but closer to what we regard as reality. So thank you and others!

Please don't. Reading the Frontiers paper was confusing, I guess that may happen when hypotheses are linked to personalities.

Makes perfect sense.

Positive citation bias and overinterpreted results lead to misinformation on common mycorrhizal networks in forests - Nature Ecology & Evolution In this Perspective, Karst et al. discuss how both the popular media and scientific literature have inflated the extent of evidence for various roles of mycorrhizal fungal networks in forests.

and the role of storytelling within and outside of the scientific community. In an opinion paper, Simard et al. respond to these justified critics. Interesting yet confusing: the burden of proof being passed back and forth, where to go from here? Part ways, conduct new experiments?

At least 3 recent papers have generated considerable debate on the interpretation of research on common mycorrhizal networks (Karst et al., Henriksson et al., Robinson et al.). They stirred questions on our relationship with epistemology, our understanding of forest functioning,
