Overview

Comprehensive survey identifies distinct microbial food web compositions across water masses, suggesting varying driving factors for trophic interactions.

Key Points

  • Microbial food webs in the Arctic Ocean have distinct compositions across different water masses, indicating ecological diversity.
  • Heterotrophic prokaryotes dominated MFWs, with significant variations in trophic-level abundance ratios observed, highlighting ecological structure.
  • Picoeukaryotes showed the steepest slope in abundance linked to temperature changes, suggesting heightened sensitivity to environmental shifts.
  • Resource availability played a crucial role in shaping microzooplankton composition, indicating bottom-up control in food web dynamics.
