Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this gap, we conducted a 32-day test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4 subsequent experiments, as well as corresponding within-river community changes. The experimental streams maintained about 80% of the invertebrates that originally colonized the introduced substrates. Many macroinvertebrate populations experienced changes in numbers through time suggesting that these taxa are unlikely to maintain static populations...
