“…This was true for all the community metrics tested. This result differs with data from temperate areas (Allan 1984, 1987, Allan et al 1988 where night drift densities can be up to 10× greater. However, this is not in agreement with previous studies of tropical streams where diel periodicity in drift was weak or nonexistent (Turcotte & Harper 1982, Pringle & Ramirez 1998, Jacobsen & Bojsen 2002, Rodriguez-Barrios et al 2007.…”

We studied invertebrate drift (intensity, propensity, and diel changes) and the recolonization process of stones in a tropical high-altitude stream in Ecuador for a period of 7 to 25 d during the wet and dry seasons. Our aim was to identify whether seasonal differences in flow produce differences in drift parameters and in the recolonization process, and to examine the role of microhabitat (fast-flow vs. slow-flow areas) in this process. Invertebrate community metrics in drift did not differ between seasons at base flow (<100 l s −1 ), but they were highly correlated with high flow events. As a result, drift propensity values for several taxa were higher during the wet season, when higher flows occurred, indicating that some taxa suffer catastrophic drift (e.g. Podonominae, Simuliidae). In the short-term experiment, taxa richness, density, and diversity of the colonizers increased with time (up to Day 7). On a longer scale (Days 7 to 25; mid-term experiment), time did not affect community metrics. Microhabitat had strong effects on the composition of colonized stones, and was related to the abundance of taxa in the drift. While some taxa that are scarce in drift were only found in slow-flow areas (e.g. Nectopsyche), suggesting that these species actively search for refuges in the stream, copious species in the drift (e.g. Baetodes) were very abundant on the recolonizing stones, especially during the wet season. The present study suggests that flow, the variability of flow (within and between seasons), and its consequences on the drift of several species play a pivotal role in invertebrate colonization and in the structuring of invertebrate communities in different microhabitats of high-altitude tropical streams.

“…Chironomids are abundant in most streams where they exhibit wide diversity (Anderson, 1967 ;McLay, 1968;Davies, 1976;Wilson & McGill, 1977;Rutter & Poe, 1978;Slack et al, 1979;Waters, 1981;Maurer & Brusven, 1983;Armitage & Blackburn, 1985;Kownacki, 1985;Obi & Conner, 1986). Chironomidae life cycles are varied and, throughout the year, a variety of drift rates and patterns can be expected (Turcotte & Harper, 1982;Raddum, 1985;Allan, 1987). Conflicting evidence exists for die1 drift periodicity of total Chironomidae larvae (e.g., Anderson & Lehmkuhl, 1968;Bishop & Hynes, 1969;Elliott & Corlett, 1972;Adamus & Gaufm, 1976;Rutter & Poe, 1978;Waters, 1981;Skinner, 1985;Allan, 1987 and references cited in Introduction).…”

Simultaneous hourly net collections in a meadow and canyon reach of a mountain stream determined die1 and spatial abundances of drifting Chironomidae larvae. Sixty-one taxa were identified to the lowest practical level, 52 in the meadow and 41 in the canyon. Orthocladiinae was the most abundant subfamily with 32 taxa and a 24 h mean density of 294 individuals 100 m-3 (meadow) and 26 taxa and a mean of 648 individuals 100 m-3 (canyon). Chironominae was the second most abundant subfamily. Nonchironomid invertebrates at both sites and total Chironomidae larvae (meadow) were predominantly night-drifting.Parakiefferiella and Psectrocladius were day-drifting (meadow) whereas 8 other chironomid taxa (meadow) and 2 taxa (canyon) were night-drifting. All others were aperiodic or too rare to test periodicity, Stempellinella cf brevis Edwards exhibited catastrophic drift in the canyon only. The different drift patterns between sites is attributed to greater loss of streambed habitat in the canyon compared to the meadow as streamflow decreased. Consequent crowding of chironomid larvae in the canyon caused catastrophic drift or interfered with drift periodicty. This study adds to knowledge of Chironomidae drift and shows influences on drift of hydrologic and geomorphic conditions.

“…Studies in temperate climates have reported a lack of similarity in the composition of macroinvertebrate assemblages and foraging patterns of brown trout, and few studies have assessed these patterns across streams, seasons, and years (Stoneburner and Smock 1979;Allan 1987;Shearer et al 2002;Leung et al 2009). In general, studies of fish growth, prey resources, and selection in temperate climates are largely restricted to spring, summer, and fall.…”

Availability and selection of macroinvertebrate prey is important to explain temporal and spatial variation in growth among stream salmonids. However, few studies contain information to identify such relationships. Our objectives were to quantify drift and benthic macroinvertebrate prey availability and selection by brown trout on a seasonal basis in five streams across three years in southeastern Minnesota. Few taxa were dominant in diets and the environment with considerable variability in drifting and benthic prey within streams and seasons. Brown trout consistently selected only one or two taxa, and displayed neutral or negative selection for other taxa. In general, large-bodied, energy-rich benthic prey were selected over other more abundant aquatic macroinvertebrate taxa and drifting prey. Foraging patterns suggested a preference of benthic feeding. Electivity of benthos and drift varied spatially and temporally with a negative relationship between the total proportion of prey available and prey electivity. In general, seasonal growth and prey electivity were not related across all streams, but were positively related within two of five streams. Understanding seasonal and spatial relationships among growth, prey availability, and prey selection may aid future management of streams, as climate change is expected to alter physical conditions and biological communities of streams.
