Worldwide, biometric research on plecopterans
has mainly involved obtaining linear measurements to determine growth in immature stages (larvae) for life-cycle and secondary production analyses (e.g., Sheldon 1969, 1980; Schmidt and Tarter 1985; Lillehamnur et al.
In addition, the plecopteran
species Anacroneuria sp.
Among the shredders displaying significant changes were plecopterans
(Peltoperlidae and Leuctra spp.) and trichopterans (Lepidostoma spp.
Additional studies show that larval caddisflies increased rates of drift in the presence of predatory fish and plecopterans
(Fairchild and Holomuzki, 2005) and increased the use of refuges when exposed to chemical cues from plecopteran
predators (Gall and Brodie, 2009).
Macroinvertebrate taxa richness varied among sampling sites (mean = 15.04; range, 3 to 29), especially Ephemeropteran, Plecopteran
and Trichopteran (EPT) taxa richness (mean = 4.48; range, 0 to 11).
