Trends in Diporeia populations across the Laurentian Great Lakes, 19972009
Abstract Benthic communities in the Laurentian Great Lakes have been in a state of flux since the arrival of dreissenid mussels, with the most dramatic changes occurring in population densities ofExpand
Effects of acid‐volatile sulfide on zinc bioavailability and toxicity to benthic macroinvertebrates: A spiked‐sediment field experiment
Lack of noteworthy pore-water zinc concentrations and lack of associated, ecologically meaningful effects were attributed to the increase in AVS levels observed with increasing SEM zinc sediment concentration. Expand
Toxicity of Bacillus thuringiensis var. Israelensis to Chironomids in Pond Mesocosms
A pond mesocosm study was conducted in a central Minnesota wetland to evaluate the potential toxicity of the microbially-derived insecticide Bacillus thuringiensis var. israelensis (B.t.i.) toExpand
Effects of Habitat Complexity on Macroinvertebrate Colonization of Artificial Substrates in North Temperate Lakes
The results were consistent with the hypothesis that the more complex, 3-dimensional artificial substrate, with its greater substrate heterogeneity, surface complexity, and interstitial space, will support a more diverse and abundant macroinvertebrate community in lakes compared to the less complex, 2- dimensional artificial substrate.

Development of new indices of Great Lakes water quality based on profundal benthic communities
Abstract Benthic invertebrate biomonitoring has long been a tool of choice for assessing the impacts of anthropogenic stress in aquatic systems. The Oligochaete Trophic Index (OTI) is used by theExpand
Biology. Ecology, Larval Taxonomy, and Distribution of Hydropsychidae (Trichoptera) in Wisconsin
,-\oout 43.000 larvae and 1800 adults of Hydropsychidae from Wisconsin were studied. 1be5e included Diplectrona modesta, Macrostemum zebratum, Parapsyche apicalis, Poramyia flam, eight species ofExpand
The non-native faucet snail (Bithynia tentaculata) makes the leap to Lake Superior
Given its potential for spread and impacts (including as waterfowl disease vector), the faucet snail warrants an elevated profile in non-native species monitoring, education, and decontamination measures in the upper Great Lakes. Expand
Effects of 4-nonylphenol on benthic macroinvertebrates and insect emergence in littoral enclosures
The observed effects of 4-nonylphenol on the benthic community were most likely due to exposure from the water, although more persistent macrophyte-associated residues may have contributed to effects on Gastropoda, Naididae, and Tanytarsini. Expand
Effects of the Insect Growth Regulator Diflubenzuron on Insect Emergence within Littoral Enclosures
Overall, significant adverse effects on insect emergence could be expected at diflubenzuron concentrations >1.0 μg/liter with the length and severity of effect being concentration dependent. Expand
