Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️... Turns out that 2/3 of these assertions are very wrong... 🌐 🦑🧪 🧵⬇️

Along with essential oils, limes have furanocoumarins in their rind that cause photodermatitis. When exposed to UV, the chemicals crosslink with the DNA of our skin cells, causing cell death. Occupational hazard of poolside bartenders! 📷: Neil Staeck CCBYNC2 #Citrus #Rutaceae #Botany 🌾🧪🌱

Our paper shows that most ectomycorrhizal fungal species (83% of OTUs) are "dark taxa": species we detect in DNA, but can't match to known species names. We map global "darkspots" - the parts of the world most in need of more research. @spun.earth @ethz.ch www.cell.com/current-biol...

The exteriors of spider eyes are part of the exoskeleton, so can't move. But in jumping spiders, the internal parts of the large central eyes have muscles that can swivel and twist to help the spider aim its eyes from inside the head. This is a 4-frame.gif showing that internal movement. 🌿🐙🕷️👀

One of the lesser known joys at Rancho del Watson is ‘checking up on things’ after decent rain. We call it the spring and it’s first in the chain of ponds running through our place. On Saturday it was a grass lined depression, now it has just started flowing. Let me show you the rest…

Saw today for the first time a seriously brilliant way to cut wildlife roadkill: virtual fencing! These devices, installed every 25m for $10K km warn wildlife by detecting approaching vehicles and emitting a flashing light and a beep. Has cut deaths by 90%! #WildOz www.abc.net.au/news/2025-06...
