What is amazing about science is that small details can have a huge impact.

Sharing a new paper led by Gavin Williams related to how giant sequoia cohorts may recruit interactively w/ low severity fire & how "colonnade" structural features may be connected to fire processes. Graphical abstract & pub link below. 🌎🧪🌾🌿🌲🍁🌱🔥 #PlantScience www.sciencedirect.com/science/arti...

The century-long era of fire suppression has resulted in dramatic decreases in giant sequoia regeneration and recruitment. A 2001 mechanical disturbance in a native grove created experimental canopy gaps ranging in size from 0.05 to 0.4 ha, where factors of giant sequoia recruitment were monitored. The patches of recruitment all burned in a 2021 wildfire, creating an opportunity to study fire-gap recruitment dynamics. The study questions were (1) what was the relationship between gap size and tree height up to the point of the fire, (2) which tree- and gap-level variables explained mortality amongst the planted trees, and (3) did a pre-fire thin-and-prune treatment increase fire-related crown damage? There was an asymptotic relationship between average tree height and gap size. Increases in gap size beyond 0.2 ha led to only modest increases in average tree height. The overall mortality rate of study trees, averaged across gaps, was 26 %, ranging from 5.0 % to 52 %. A generalized linear mixed-effects model (GLMM) was fit to determine factors of mortality. Taller trees had lower probability of mortality, followed by trees closer to the centers of gaps. The pre-fire thin-and-prune treatment did not have a statistically significant effect on mortality or crown damage. A key finding was that canopy gaps facilitated giant sequoia recruitment by altering the resource environment while also altering patterns of fuel accumulation. Tree height was maximized in gaps greater than 0.2 ha, but gaps as small as 0.05 ha protected interior trees from fire.

Honestly, a pretty helpful description of what happens to cause cross-bridge formation when calcium is released in muscle 😂 (vertebrate physiology meme courtesy of @lsubiosci.bsky.social undergrad Ralph Junius) 💪 🧪

A version of the "distracted boyfriend" meme where the boyfriend is labeled "actin" the annoyed girlfriend is labeled "troponin" and the girl in the red dress is labeled "myosin head".

BOOSTER, a newly identified orphan gene, supercharges photosynthesis and, when overexpressed, boosts height of poplars by up to 200% (at least in greenhouse) To make it even more interesting, part of the gene seems derived from a poplar fungus-farming ant 🐜 Paper: www.cell.com/developmenta...

Figure from the paper, showing BOOSTER-overexpressing poplar plants that are about twice as tall as the negative controls. Googly eyes (not from original paper) look at the taller plants.

Hey 👋🏾, I’m a French Student at Clermont University. I’m Studying Biology cellular and physiology. I’m hesitating between specializing in human pathophysiology research or plant phytopathology. I would like to pursue a PhD in an English-speaking country. If you have any advice, I’m all ears !
