La traque des indices de biocorrosion laissées par les chauves-souris en grotte ce poursuit. C’est confirmé, des chauves-souris ont bien occupé la grotte de la Cocalière, avant que l’entrée se referme naturellement ! #karst #bats #grotte #géomorphologie #écologie #gard @umr5608traces.bsky.social

New paper! 🧪 How can we work at the interface between climate science and evolutionary anthropology, to understand the complex feedbacks between cultural systems and climate change? It turns out that the answer might involve some ecological modeling!

This is figure 1, which shows the taxonomic identification of the 173 bone specimens analyzed using ZooMS, and examples of the main categories of elements.
Humans may have been making tools from whale bones up to 20,000 years ago, according to evidence presented in Nature Communications. go.nature.com/4kePeD6 🏺 🧪

Wonderful pareidolia formed by a naturally fallen aragonite stalactite on the floor of a cave in #Botswana. You really don’t need much imagination here…

Bat sanctuary in Gcwihaba Caves, #Botswana. This chamber is known as the MOAB « Mother Of All Bats. » For now, they are simply gathering for the upcoming breeding season. They will be a lot more numerous soon!

Nature's secret artists! Biocorrosion has polished these cave walls, and the thick dark bacterial biofilm above is still actively reshaping the underground world.
