Our work, just published in Plant Communications, solves the mystery of how giant waterlilies achieve such size. We deep-dived into their genomes & found a massive accumulation of cells in early development to offset production costs: like paying for bricks cheap, upfront, before building the house.
Giant waterlilies produce the world’s largest floating leaves. Our work, just published in Plant Communications, solves the mystery of how they achieve such dimensions at the molecular level. We deep-dived into their genomes and found a massive accumulation of cells early in leaf development. This early investment in cells enables an efficient vein transport system which offsets the costs of producing such enormous architecture. It’s like paying for your bricks cheap, upfront, before building your house. https://www.cell.com/plant-communications/fulltext/S2590-3462(25)00104-X

An important review - The ecology of plant extinctions - "Recent warm-edge extirpations demonstrate the growing impact of anthropogenic climate change & show that predictions of massive climate-driven extinctions later this century are plausible" www.sciencedirect.com/science/arti... 🌾🌎🧪🌐
Image of the first page and abstract of the paper "The ecology of plant extinctions Author links open overlay panel Richard T. Corlett 1 2 Show more Add to Mendeley Share Cite https://doi.org/10.1016/j.tree.2024.11.007 Get rights and content Highlights The fossil record suggests that climate change was the major driver of plant extinctions and regional extirpations from the Pliocene until recently, when anthropogenic habitat loss became dominant. Known recent plant extinctions are disproportionately few in comparison with well-studied animal taxa, but many more species are probably committed to inevitable extinction unless given targeted support. Recent warm-edge extirpations demonstrate the growing impact of anthropogenic climate change and show that predictions of massive climate-driven extinctions later this century are plausible. The proximate causes for population extirpations are still rarely known but are likely to be highly varied and both species and location specific."

The only freedom appears to be if I do some work on Saturday or Sunday each week.

I've been in a faculty position for 2 years and a bit, this is all I've known but myth says it used to be better. I'd happily try out another system.
drkevinrmcclure.com Kevin R. McClure @drkevinrmcclure.com · Dec 3
The freedom faculty enjoy is false. Yes, we have a lot of discretion over how we spend our time, but the job demands have become so numerous and disconnected that the most common result is constant frenzy.

🌡️🌱 New article in @aobp.bsky.social exploring how individual plants' phenological responsiveness to temperature varies across species ranges and is influenced by local climate conditions

Full #openaccess
👉 https://buff.ly/3Z6swVz

#PlantScience
Intraspecific variation in phenological temperature sensitivity across climatic gradients in MAT and IVT. Color scales are centered on the overall average baseline temperature sensitivity (−2.28 days/°C). Temperature sensitivity values are marginal estimated slopes based on the MAT and IVT of a given observation site, extracted from the global model (n = 23 220, df = 23 100, adjusted R2 = 0.817). (A) Heat map of temperature sensitivity across gradients of MAT and IVT. (B) Geographic map of estimated temperature sensitivity across the study range. Points represent geolocated species observations from iNaturalist and color value represents the estimated temperature sensitivity of plants in that location.
