- Sympatric species maintain divergent food habits (feeding ecology) in order to release each other from competing for limited food resources (1, 2).
- Two congeners coexist in North American lakes: suction-feeding bluegill, Lepomis macrochirus feeds primarily on soft, elusive, and planktonic prey whereas durophagous redear, Lepomis microlophus eats hard-shelled invertebrates such as clams (1, 2).
- Is ecological divergence consistent with functional or biomechanical divergence in these sympatric fishes?
- This study compares growth trajectories of feeding biomechanics that underlie feeding performance in sympatric Florida sunfishes with the dietary prey items.
