Emergence of Chironomidae (Diptera) from Char Lake, Resolute Northwest Territories
Quantitative data, using [Formula: see text]-m 2 submerged traps, were obtained on the six common chironomid genera in Char Lake, at latitude 74°56′ N. Emergence of each species was highly synchronized and in 1972 occurred partly or wholly beneath ice. Each species had different emergence distributi...
