Last weekend, VOLT joined the #Fungi Festival๐Ÿ„๐Ÿ„โ€๐ŸŸซ.

Visitors got to hear a talk on hidden #fungaldiversity in #caves, and explored a collaborative booth. Here they could peek at fungal cultures under a microscope๐Ÿ”ฌ, watch a short film highlighting the research, and learn about cave fungi and #VOCs.

We measured #VOC & #CO2 fluxes from 3 ponds in a peatland forest using floating chambers. Understanding of freshwater ecosystems as VOC sources is poor, so this work led by Y. Qin, published in #ASLO_LO provides important new data.
