Individual return patterns of spawning flannelmouth sucker (Catostomus latipinnis) to a desert river tributary
Tributaries provide temporal and spatial habitat heterogeneity in river networks that can be critical for parts of the life history of a species. Tributary fidelity can benefit individual fish undergoing spawning migrations by reducing time and energy spent exploring new areas and leveraging previous experience, but anthropogenic activities that fragment or degrade these systems can eliminate thos
Handling effects on dispersal of PIT-tagged Flannelmouth Sucker
ObjectiveHandling and tagging migrating fish might alter their behavior, limiting inference from mark–recapture studies. Posthandling flight of tributary spawning Flannelmouth Sucker Catostomus latipinnis was previously identified in Coal Creek in the upper Colorado River basin. Our objective was to determine if similar issues were present at McElmo Creek in the San Juan River basin.MethodsWe comp
Amphibian monitoring in hardwood forests: Optimizing methods for contaminant‐based compensatory restorations
Amphibians such as frogs, toads, and salamanders provide important services in aquatic and terrestrial ecosystems and have been proposed as useful indicators of progress and success for ecological restoration projects. Limited guidance is available, however, on the costs and benefits of different amphibian monitoring techniques that might be applied to sites restored in compensation for contaminan

From Tread to Watershed: How Tire Wear Particle Chemicals 6PPD and 6PPD-quinone Are Impacting Waterways
Tire and road wear particles (TRWPs) are generated during normal driving conditions and contain both rubber and roadway materials. These particles travel from the roadways and urban environments into surrounding ecosystems where there are deleterious impacts from both the TRWPs and leached rubber chemicals. Recent studies have demonstrated the widespread occurrence and toxicity of TRWPs and their...
Study Finds PFOSA Can Suppress Immune Function in Developing Zebrafish (Danio rerio)
The Stockholm Convention has labeled PFOS a “persistent organic pollutant” due to its long-enduring prevalence, negative toxicological effects, and ability to bioaccumulate in living things. Concerns about PFOSA have been raised due to its similarity to PFOS, its ability to metabolize into PFOS, and its persistent use today
Agricultural Pesticides Could Be Impacting the Natural Beauty at Sequoia National Park Through Atmospheric Deposition
High up in the remote alpine and subalpine lakes of Sequoia and Kings Canyon National Park (SEKI), the crystal-clear lakes appear to be greening with an overpopulation of periphyton. Periphyton is a mixture of various water microbes such as algae, cyanobacteria, and others. Scientists at the USGS Columbia Environmental Research Center and the University of Missouri are working with National Park...
