- 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

- Many thanks to the Romanian, Swiss, and Italian team for this fruitful collaboration. We successfully collected two substantial cores of bat guano from Sura Mare Cave, #Romania. We are now beginning the search for paleoenvironmental insights @cnrsecologie.bsky.social @umr5608traces.bsky.social

- These features look like classical karst formations, but these cupolas are actually the result of biocorrosion caused by bats. Cioclovina Cave in #Romania is a fascinating example of how bat colonies can reshape a cave! #karst #bats #cave #biocorrosion #Transylvania @umr5608traces.bsky.social

- Geoarchaeology in caves requires caving skills to access archaeological sites. At the bottom of this 20m shaft, an interesting Neolithic site was discovered, which at the time was accessible through a different entrance @umr5608traces.bsky.social @cnrs.fr #karst #archaeology #caving #Gard #Occitanie
