This dataset is associated with an examination of environmental DNA (eDNA) from the invasive round goby (Neogobius melanostomus) in parallel with visual surveys of fish count and size conducted by...

Benthic invertebrates are important trophic links in aquatic food webs and serve as useful bioindicators of environmental conditions because their responses integrate the effects of both water and...
-
Benthic macroinvertebrates are an abundant, diverse, and ecologically important component of aquatic ecosystems. They are also widely used to infer water quality and overall ecosystem health...

Sediment particles can strongly bind metals, effectively repartitioning them from solution to a solid phase. As a result, sediments may accumulate and retain metals released to an aquatic...
