Secondary Production, Emergence, and Export of Aquatic Insects of a Sonoran Desert Stream

Aquatic insect secondary production, emergence, and export of adults to the adjacent terrestrial ecosystem were assessed in Sycamore Creek, Arizona, by means of benthic sampling, emer- gence traps, and catch-nets that passively sampled adults falling into the stream. Annual secondary production was 120.9 ? 18.0 g-m-2 yr-t and emergence was 23.1 g.m-2 yr-t (in dry mass units). The ratio of annual emergence to annual production (E/P) varied among taxa and ranged from 2 to 29%. Chironomids comprised 48.2% of production and 59.7% of emergence and mayflies accounted for 45.9 and 19.2%, respectively. Approximately 3% of emergent insect biomass returned to the stream; thus 22.4 g m-2 yr-I was transferred to the adjacent terrestrial ecosystem. The transfer of a significant portion of aquatic insect biomass to the terrestrial habitat reduced insects available to stream insec- tivores while providing prey for insectivores in neighboring terrestrial ecosystems.
