Impacts of invasive Asian (Amynthas hilgendorfi) and European (Lumbricus rubellus) earthworms in a North American temperate deciduous forest
Current understanding of earthworm invasions in North America is founded on studies of European species belonging to a single family (Lumbricidae); the ecological effects of taxa from other regionsExpand

The cost of tolerance: sensitivity of stream benthic communities to UV-B and metals.
The ability to tolerate disturbance is a defense strategy that minimizes the effects of damage to fitness and is essential for sustainability of populations, communities, and ecosystems. Despite theExpand

Optical bioassay for measuring sublethal toxicity of insecticides in Daphnia pulex.
Many emerging contaminants tend to be biologically active at very low concentrations, occur in water as part of complex mixtures, and impact biota in ways that are not detected using traditionalExpand

Invading the invaders: reproductive and other mechanisms mediating the displacement of zebra mussels by quagga mussels
Dreissenids are invasive bivalves, native to water bodies of the Ponto-Caspian region of southwestern Asia. Following dispersion in Europe in the early nineteenth century, they were accidentallyExpand

A Kinetic Study of Accumulation and Elimination of Microcystin-LR in Yellow Perch (Perca Flavescens) Tissue and Implications for Human Fish Consumption
Fish consumption is a potential route of human exposure to the hepatotoxic microcystins, especially in lakes and reservoirs that routinely experience significant toxic Microcystis blooms.Expand

Methoprene and 20-OH-ecdysone affect male production in Daphnia pulex.
Exposure of Daphnia pulex to the insecticide and juvenile hormone-mimic methoprene resulted in a decrease in the incidence of all-male broods and an increase in the incidence of all-female broodsExpand
