Cross-ecosystem impacts of stream pollution reduce resource and contaminant flux to riparian food webs.
The effects of aquatic contaminants are propagated across ecosystem boundaries by aquatic insects that export resources and contaminants to terrestrial food webs; however, the mechanisms drivingExpand

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

Metamorphosis alters contaminants and chemical tracers in insects: implications for food webs.
Insects are integral to most freshwater and terrestrial food webs, but due to their accumulation of environmental pollutants they are also contaminant vectors that threaten reproduction, development,Expand

Critical tissue residue approach linking accumulated metals in aquatic insects to population and community-level effects.
Whole body Zn concentrations in individuals (n = 825) from three aquatic insect taxa (mayflies Rhithrogena spp. and Drunella spp. and the caddisfly Arctopsyche grandis) were used to predict effectsExpand

Barriers Impede Upstream Spawning Migration of Flathead Chub
AbstractMany native cyprinids are declining throughout the North American Great Plains. Some of these species require long reaches of contiguous, flowing riverine habitat for drifting eggs or larvaeExpand

Changes in dissolved organic material determine exposure of stream benthic communities to UV-B radiation and heavy metals: Implications for climate change
Changes in regional climate in the Rocky Mountains over the next 100 years are expected to have significant effects on biogeochemical cycles and hydrological processes. In particular, decreasedExpand

Lagrangian sampling for emerging contaminants through an urban stream corridor in Colorado.
Abstract:  Recent national concerns regarding the environmental occurrence of emerging contaminants (ECs) have catalyzed a series of recent studies. Many ECs are released into the environment throughExpand

Characterizing invertebrate traits in wadeable streams of the contiguous US: differences among ecoregions and land uses
Abstract.  Much is known about invertebrate community traits in basins across Europe, but no comprehensive description of traits exists for the continental US. Little is known about the traitExpand
