The hyporheic assemblage of a recently formed stream following deglaciation in Glacier Bay, Alaska, USA

A diverse hyporheic assemblage of 19 taxa, including copepods, ostracods, cladocerans, tardigrades, and macroinvertebrates, was identified in a recently deglaciated stream in Glacier Bay, Alaska. The study found significant variation in community composition between sites and years, with abundance and diversity being higher where salmon redd-digging disturbance was minimal. This research provides insights into the development of hyporheic communities during primary succession, relevant to both natural and engineered river systems. The investigation used modified PVC wells at four contrasting sites over two years, collecting data on stream temperature, discharge, and suspended solids.
