Colonization and ecological development of new streams in Glacier Bay National Park, Alaska
SUMMARY 1. Colonization and ecological development of postglacial freshwater communities was investigated in Glacier Bay National Park, south‐eastern Alaska, following the rapid recession of a Neo‐glacial ice sheet within the last 250 years. 2. Environmental variables shown to be most significant in...
