The Life Cycle of Baëtis macani Kimmins (Ephemerida) in a Norwegian Mountain Biotope
Abstract The life cycle and aspects of the biology of Baëtis macani, a species restricted to Fennoscandia, are described from a small lake and its outflow at 1330 m a.s.l. near Finse, Norway (60°36' N, 7°30' E). Additional data are presented from Øvre Heimdalsvatn, a subalpine lake in the...
