G.A. Swanson J. MacKay N.H. Euliss Jr. 1992 Sampling devices that minimize bias and function in aquatic habitats used by waterfowl are needed. We devised a multiple tube sampling device for quantitative sampling of small (< 3 cm) aquatic invertebrates in wetlands. The sampler reduced bias associated with sampling macroinvertebrates that utilize the benthic-pelagic interface because it simultaneously collects benthic and water column invertebrates. The sampler was statistically superior to other sampling devices because each sampling effort provided 4 subsamples and a within-sample variance that could be estimated. The device also was durable and reasonably inexpensive to construct. application/pdf 10.2307/3808807 en Wiley Multiple tube sampler for benthic and pelagic invertebrates in shallow wetlands article
