Periphyton flora of some lotic and lentic environments of Hope Bay (Antarctic Peninsula)

A taxonomic study was made of the periphytic algal flora of some freshwater environments at Hope Bay, Antarctic Peninsula (63°27′S; 56°59′W), during summer 1992-1993. Seven lakes and two pools that are characterized by different trophic levels were studied. The largest, Boeckella Lake, has an import...
