Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes. [PDF]
Ecol EvolPredator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

River connectivity increases the diversity of fish communities in gravel pit lakes
Transactions of the American Fisheries Society, Volume 152, Issue 5, Page 550-576, September 2023., 2023 Abstract Objective Off‐channel floodplain features are important components of a river system that provide habitat and boost regional species pools, but river–floodplain connectivity is disrupted by anthropogenic activities. The Campbell Lakes in Harrison, Ohio, are formerly isolated gravel pits along the Whitewater River and are connected to the river
