The hyporheic assemblage of a recently formed stream following deglaciation in Glacier Bay, Alaska, USA
Many studies focus on the recovery of stream communities following disturbances such as high flows (secondary succession); relatively few examine community composition in streams undergoing primary succession and even fewer detail the hyporheic community in such streams. We examined the composition...
