“…Many chironomid taxa exhibited nocturnal periodicity, some were aperiodic, and for many there were insufficient data to estimate their behavioural drift. This differs from TILLEY (1989), finding that many species were aperiodic in a mountain stream. But note, that drift pattern of the same chironomid species may vary spatially and temporally with hydrologic and geomorphic conditions of rivers (FERRINGTON, 1984).…”

“…Chironomid drift in rivers is often dominated by first and second instar larvae which constitute 'distributional' drift (FERRINGTON, 1984;STOREY and PINDER, 1985;WILLIAMS, 1985WILLIAMS, , 1989GRZYBKOWSKA et aL, 1987;TILLEY, 1989). However, the net mesh size used in the Warta River, called 'a standard net' by BENKE et al (1986), was insufficient to catch the earliest instars of midges.…”

The diel drift patterns of Chironomidae larvae were investigated in a seventh order section of the Warta River (Central Poland) over two diel cycles during May 1989. Three nets (mesh size 400 pro) were installed in a cross section of the Warta River.The estimated drift density was low, but was comparable to that calculated for other large rivers. Spatio-temporal fluctuations in abundance and composition of macroinvertebrate drift, including Chironomidae, were observed with the highest density of drifting macrobenthos recorded near the depositional bank of this river. The ratio benthosdrift indicated differing propensities for of the older instars of a given chironomid taxon to drift. Orthocladiinae larvae were the most abundant subfamily of Chironomidae in drift but not in benthos, reaching up to 73% of the total drifting chironomid larvae. More taxa but fewer individuals (about 20% of the chironomid larvae collected) belonged to the tribe Chironomini, the dominant group in benthos.

“…In general, drift density was similar or higher than published data from other high‐altitude streams (e.g. Allan, 1987; Tilley, 1989; Waringer, 1992) and lake outlets (Kownacki et al ., 1997). However, these drift densities are not directly comparable as the mesh size of the drift nets varied among studies and some expressed drift only in terms of abundance (e.g.…”

“…Chironomidae dominated the drift at all sites and are a major component of the drift in other high‐altitude streams (e.g. Bergey & Ward, 1989; Tilley, 1989; Tockner & Waringer, 1997; Robinson et al ., 2002). Drift in kryal streams generally consisted of few taxa, predominantly Chironomidae (also see Ilg et al ., 2001; Robinson et al ., 2002).…”

SUMMARY 1. We examined the seasonal and diel patterns of invertebrate drift in relation to seston and various habitat characteristics in two each of four different kinds of alpine streams [rhithral (snow‐fed) lake outlets, rhithral streams, kryal (glacial‐fed) lake outlets and kryal streams]. Samples were collected at four times of the day (dawn, midday, dusk and midnight) during three seasons (spring, summer and autumn). 2. Habitat characteristics differed mainly between rhithral and kryal sites, with the latter having higher discharge and turbidity, lower water temperature, and higher concentrations of ammonium, and particulate and soluble reactive phosphorus. Seasonality in habitat characteristics was most pronounced for kryal streams with autumn samples being more similar to rhithral sites. 3. The concentration of seston was lowest in the glacial‐influenced lake outlets and slightly higher in the stream sites; no seasonal or diel patterns were evident. 4. The density of drifting invertebrates averaged less than 100 m−3 and was lowest (<10 m−3) at three of the four kryal sites. Taxon richness and diversity were lowest at rhithral lake outlets. Chironomidae dominated the drift as well as benthic communities and <30% of benthic taxa identified were found in the drift. 5. Drifting invertebrates showed no consistent seasonal pattern. However, density tended to be highest in spring at rhithral sites and in autumn at kryal sites. No diel periodicity in drift density was found at any site and the lack of diel pattern may be a general feature of high altitude streams. 6. Glacially influenced habitat parameters were a major factor affecting drift in these alpine streams, whereas no clear differences were observed between streams and lake outlets. Our findings indicate that invertebrate drift in alpine streams is primarily influenced by abiotic factors, and therefore, substantially differs from patterns observed at lower altitude.

1. The Calapooia River in western Oregon supports a small winter steelhead trout (Oncorhynchus mykiss) population and historically supported spring Chinook salmon (Oncorhynchus tshawytscha). Early timber harvesting removed the riparian forest, and log transportation practices simplified the channel. Those disturbance legacies continue to affect fish habitat by limiting shade and channel complexity, complicating conservation efforts.2. To evaluate juvenile salmonid rearing potential, macroinvertebrate drift, thermal regime and physical habitat were measured at eight sites in 24 km of the upper river during late summer baseflow.3. Overall physical habitat was simple, with few functioning instream structures or pools. During the 22-day drift study, flows declined and maximum site stream temperatures ranged from 23.1°C at the lower end to 16.4°C 24 km upstream.4. Macroinvertebrate drift concentrations ranged from 0.7-13.7 ind. m −3 with biomasses from 0.02-1.23 mg m −3 . Drift concentration biomass was higher upstream (P = 0.006) than downstream and declined overall (P < 0.001) during the study. Drift biomass was dominated by five taxon groups -Baetis tricaudatus, Calineuria californica, Hesperoperla pacifica, Simulium spp., and Chironomidae, which were 65% of total biomass. During twilight, total biomass and biomass of B. tricaudatus, Simulium spp., and Chironomidae (both larvae and adults) were higher. 5. Total drift declined dramatically over the study period owing to decreases in drift concentration and a 58% decline in discharge, greatly reducing overall drift and available food resources for juvenile-rearing salmonids.6. The upper catchment, both with cooler temperatures and higher food availability, provided the best conditions for juvenile anadromous salmonids to survive late summer conditions. Conservation consequences of climate change-induced alterations in flow and temperature may further affect habitat quality for juvenile salmonids in this catchment in the coming decades.
