Once in a while I venture out of the Paleozoic to look at younger weird plants... Hermanophyton is a genus based on silicified stems from the Jurassic of the US. It is very likely a gymnosperm but beyond that its affinities are, well, "obscure". #paleobotany #FossilFriday 🌿⛏️ 🧵 1/3

🌿🔥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....

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.
