Abstract
Mayfly ecology was studied in the lake, Øvre Heimdalsvatn, 1090 m a.s.l. in the Jotunheimen Mountains. Life cycle, winter growth, biomass, nutrition, predation, emergence and fecundity are considered. The four main species have adopted different strategies - Baetis macani has opted for low mortality and rapid summer growth, Siphlonurus lacustris for large size and high biomass, Leptophlebia vespertina for high density and L. marginata for winter growth. Each strategy has its disadvantages, but they enable coexistence in spite of the environmental restrictions imposed by a long period of lake ice cover and a short summer.
