Published: 1 April 2020
Over 400,000 beetle species exist, with ~13,000 adapted to freshwater habitats like ponds and streams. Some live fully aquatic lives, others partly. None live in the sea, though coastal beetles forage along shores.

Published: 7 April 2020
Scripps and SDSU researchers found that closely related hawkfish species coexist on South Pacific reefs by eating different prey. Gut content sequencing showed dietary partitioning, helping explain their biodiversity.
