Diversity and interdomain networks of bacterial, pico-protist and nano-protist communities in a marine ranching.

ABSTRACT: Microbes of diverse sizes and classifications collaborate to mediate a variety of biogeochemical processes. Although seasonal fluctuations in environmental variables generally influence microbial community dynamics, our comprehension of interdomain microbial co-occurrence patterns remains incomplete. Here, we analyzed high-throughput sequencing datasets of bacteria, pico-protists (0.8-2 μm) and nano-protists (2-20 μm), and their seasonal changes in coastal marine ranching ecosystems. Our findings revealed that, in terms of trophic groups, pico-protists predominantly comprised parasites, whereas nano-protists had a higher proportion of mixotrophs. Microbial communities shifted with seasona, mainly in response to temperature, dissolved oxygen, and salinity. Interdomain microbial networks sho
