Interested in how #wheat 🌾 might perform during future climare extremes? The @sheffielduni.bsky.social press team have covered our latest research from the @drhollycroft.bsky.social lab 👇
🌾 Wheat provides around 20 per cent of daily calories worldwide. But a new study led by @drhollycroft.bsky.social and @bc247.bsky.social has discovered wheat crops could use considerably more water than expected during extreme future heatwaves... #cop30

Happy to share our latest article in @newphyt.bsky.social. We look at the impacts of high atmospheric CO2, heatwaves, nitrogen fertiliser and drought on #wheat stomatal performance, photosynthesis, water usage and yield. @drhollycroft.bsky.social nph.onlinelibrary.wiley.com/doi/full/10.11…

🌲 What if a terrestrial laser scanner cost ~€2k, and still delivered reliable forest data?
We built one. And it works.
→ DBH accuracy ~1.5 cm
→ Tree height ~1 m
→ Open hardware + open software
Accessible 3D forest monitoring
Wherever you are, get in touch 🌍
Preprint: bit.ly/3HneatY

Woodland stewards can help improve the biodiversity of forests by leaving behind cavity trees, dead standing trees and downed dead trees. Learn more about the positive impact of of maintaining these trees from Extension Forester Anna Stockstad 🌳 ⬇️ buff.ly/1skM0wW
Building biodiversity in your forest: Cavity trees, snags, and deadwood
Cavity trees, dead standing trees, and downed dead trees create habitat for many species of mammals, birds, insects, amphibians, and reptiles, which positively impacts the rest of the ecosystem.

Well, this is exciting, a first ever foray into 🌳 stomata. First up, the "living fossil" Ginkgo biloba, and the tulip tree 🌷Magnolia soulangeana. Can't wait! @drhollycroft.bsky.social

1/4 Delighted to share our latest preprint "Future heatwave conditions inhibit CO2-induced stomatal closure in wheat". We found that high CO2, high VPD heatwave treatment prevents stomatal responses to light, super-elevated CO2 and nitrogen fertiliser application. www.biorxiv.org/content/10.1...

No winter halt in below-ground wood growth of four angiosperm deciduous tree species - Nature Ecology & Evolution
As wood growth in deciduous tree stems halts during winter, it has been assumed that wood growth in coarse roots follows the same pattern. This study on the growth of stem and coarse roots of four Eur...

Good piece by @natureportfolio.bsky.social. The erosion of thinking time—driven by admin, bureaucracy, industry agendas, and unrealistic output targets—stifles curiosity-led science. These pressures undermine innovation and the intellectual freedom vital for real progress. 🧪🌱🌍 #ScienceIsNotBusiness
