Okinawa had its hottest September at 1.6C above the average. I filmed this mass coral bleaching last year, but didn't have the heart to share. Total annihilation of the first few meters of depth. This stuff happens before our eyes, and yet people who think it isn't real keep gaining power.

What sustains biodiversity? 🌿🌸🐝🐦‍⬛ It’s not just about species, it’s also about individuals.

Our new paper in @esajournals.bsky.social Ecol. Monogr. shows how the way individuals specialize on their mutualistic partners can scale up to shape species persistence.

Bridging the gap between individual specialization and species persistence in mutualistic communities

Mutualistic interactions among organisms are fundamental to the origin and maintenance of biodiversity. Yet, the study of community dynamics often relies on values averaged at the species level, igno...

Raby et al. provide a comprehensive, practical guide for designing and conducting experiments to measure critical thermal limits, with an emphasis on CTmax 🌍 🧪 👇

buff.ly/iZN6Xdg

Diagram of a template design for a CTmax apparatus. Aeration, mixing mechanisms (pump), and heating elements are in an ‘equipment section’ that is physically separated with a screen from the part of the arena containing the animals (‘animal arena’; here with fish). A submerged temperature sensor (or data logger) is used to log temperatures, in addition to a temperature sensor with a display that is used to score CTmax in real time. The time and temperature should only be visible to the data recorder (and/or video camera), not to the person observing animals for end points.

White sharks (Carcharodon carcharias) almost went bottom-up during the last ice age, when sea levels were much lower than they are today and sharks had to get by with less space.
