@ 1982, by the American Society of Limnology and Oceanography, Inc. Production dynamics of some arctic Chironomus larvae
Production and standing stock were determined for a two-species population of Chirono-mus larvae in a tundra pond near Barrow, Alaska, from 1975 through 1977. These larvae take 7 years from recruitment to adult emergence, and a multicohort population was always found. Cohort-specific values for stan...
