“…Thus, the larvae are likely to experience more severe extremes of temperature and low oxygen in their natural environment. Genkai-Kato et al (2005) reported that the probability of stonefly presence was positively correlated with the current velocity of a stream in summer but not in winter because of relatively low oxygen levels in summer. Therefore, the stream flow-dependent distribution of glossosomatid larvae may be more significant in summer (we performed our survey in winter) because of lower oxygen levels in the water and higher rates of oxygen consumption.…”

In aquatic systems, oxygen availability is often a limiting factor affecting animal distribution. We documented the distribution of case-bearing caddisfly larvae (Glossosoma) in a riffle of the Hirose River, Japan, and found that larval density increased with increasing current velocity. We also experimentally measured the effect of flow and case morphology on oxygen consumption and mortality. Larvae were divided into ''perforated'' and ''closed'' case treatment groups where gaps in the upper side of the dome-shaped case were left open or closed. They were placed in either lotic or lentic conditions. Oxygen consumption was higher in the lotic compared to the lentic environment for both groups, and was higher in individuals of the perforated-case group than in those belonging to the closed-case group in both environments. Larval mortality was lower under lotic conditions than lentic conditions for the perforated-case group, and higher in the closed-case group in both environments. Our results suggest that larvae prefer areas with high current velocity as they are otherwise unable to obtain sufficient oxygen because of their lack of undulatory behavior. Furthermore, gaps in the larval case appear to enhance passive gaseous exchange via water flow. We also discuss the functional significance of the glossosomatid case.

Estimates of biomass are essential for studies modeling the structure, animal growth, production, and energy fl ow in ecosystems. The relationships between dry weight and head capsule width or body length in summer and winter were examined for four species of predatory stonefl y (Perlidae) nymphs in Japan. There were some variations in regression constants between seasons and species. However, the distribution of length-weight plots did not show marked differences between species or season. Our results suggest that length-weight relationship data, regardless of season or including multiple species, are also valid for estimation of dry weight when the target species are classifi ed into the same taxonomic family.

“…Additionally, nymphs of multiple mayfly genera were reported in more exposed positions on cobbles and exhibited abdominal positioning by holding their bodies off the substrate at lowered DO concentrations (Wiley and Kohler, 1980). The presence of a second macroinvertebrate order, Plecoptera, was correlated with velocity magnitude and oxygen renewal rates in summer but not in winter because of the warmer temperature and low DO in summer (Genkai-Kato et al, 2005). Genkai-Kato and colleagues specify that this behavior was not due to an oxygen gradient as DO concentrations did not differ between deep and shallow sampling points in winter or summer (Genkai-Kato et al, 2005).…”

SUMMARYLaboratory measurements of dissolved oxygen (DO) uptake by Glossosoma nigrior Banks were conducted in a sealed, recirculating flume under variable fluid flow velocities. Measurements were performed in similar water temperatures, DO concentrations and fluid flow velocities to field conditions in the stream where the larvae were obtained. Total oxygen uptake by both cased larvae and corresponding cases without larvae were quantified. An increased fluid flow velocity corresponded to an increased larval DO uptake rate. Oxygen uptake by the larval cases alone was not as sensitive to changes in the Peclet (Pe) number, the dimensionless ratio of advective to diffusive DO transport, as uptake by larvae themselves. The flux of DO to larvae and their cases was up to seven times larger in a moving fluid in comparison to non-moving fluid conditions in the proximity of larvae for 087, larvae typically remained in their cases. This indicates that oxygen delivery to the larvae at low Pe is insufficient to satisfy the respiratory demands of cased larvae.
