Interannual variability in the trophic niche of young‐of‐year fish belonging to four piscivorous species coexisting in a natural lake

S Westrelin, P Balzani, PJ Haubrock… - Freshwater …, 2023 - Wiley Online Library
Predatory fish species play a key role in aquatic ecosystems by exerting top‐down control
