Volcanic lakes are unique ecosystems often characterised by distinct physicochemical conditions that shape microbial biodiversity and community dynamics. However, the ecological roles, biodiversity, coexistence patterns, and assembly mechanisms of abundant and rare microeukaryotic biospheres in these environments remain poorly understood. Here, we investigated their distinct patterns in water and sediment from volcanic lakes i...

Humans have long been fascinated by the mysteries surrounding fish migrations and addressing these complex behaviors often requires large data sets. Biogeochemical tags, including trace elements and stable isotopes, are the most accessible biomarkers for tracking fish migrations. However, access to standardized biogeochemical tag data is rarely available for migratory fish, which limits our understanding of the evolutionary or...
