- Reposted by Lawren SackI'm very sad to say William Bond, of the University of Cape Town & Fellow of the Royal Society (@royalsociety.org ), has passed away. It is a great loss. He was an enthusiastic ecologist and a critical thinker. I learned a lot, and I still had a lot to learn from him. RIP. 😢 🧪🌎🔥🌿🌳🪴🌐 #PlantScience

- Saddened to hear about the passing of Steve Long. His work had a profound impact on plant science. A true loss to the scientific community. @ripeproject.bsky.social emails.illinois.edu/newsletter/4...
- Reposted by Lawren SackWind and frost have surprisingly strong effects on global patterns in leaf cuticle thickness! Latitude, biome and taxonomy matter too. Other climate variables not so much. #trait research from international team including @lawrensack.bsky.social @westobymark.bsky.social. doi.org/10.1111/nph....

- Reposted by Lawren Sack🌿 Excited to share our latest preprint! We tracked how plasmodesmata numbers evolved across the path from C₃ → C₄ photosynthesis in Flaveria - and found a stepwise increase in cell-to-cell connectivity. Thoughts or feedback are most welcome 😊 #PlantScience

- Reposted by Lawren SackBalanophora is a parasitic plant that lacks chlorophyll, and steals its nutrients from tree roots. It lives beneath the rainforest floor, where once in a while, it sends up an orb that glows like the moon.

- Reposted by Lawren SackExcited to see this paper from Mary Van Dyke out in press- she measures how rainfall manipulations alter the timing of the life cycles of California annual plants, and explore implications for species coexistence. Thanks to Sedgwick UCNRS Reserve for facilitating her research! #AJB
