Lake size is associated with the relationship between body mass and gut microbiota alpha diversity in threespine stickleback (Gasterosteus aculeatus)

Lake size is associated with ecological conditions that can affect the microbiome of hosts, such as diet and habitat characteristics. However, whether host-microbe interactions are affected by lake size remains poorly understood. We characterized the gut microbiota of 191 wild th...

Grazing abandonment in Iceland: unearthing the consequences for root biomass and community-level root functional traits

Abstract Background and aims In northern ecosystems, plants allocate biomass predominantly to roots, which are central to the transfer of recent photosynthate from plants to soil and thus soil carbon accumulation. Grazing typically modifies above-ground vegetation composition and...
