Comparative sugar utilisation and metabolism of mannose as co-substrate indicate flexibility in carbon metabolism in anaerobic gut fungi

Anaerobic gut fungi (AGF) are key degraders of plant biomass in ruminants, yet there is limited knowledge of how AGF respond to mixtures of plant-derived sugars. Here, we assessed monosaccharide and disaccharide utilisation by Neocallimastix frontalis CoB3, Caecomyces communis SHB, and Piromyces edwardsiae SHC, which are abundant in the rumen microbiome. While all AGF isolates shared a core set…

Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island

Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species.
