Closing the gap between science and management of cold-water refuges in rivers and streams
(JOURNAL) [Published : Oct 01, 2023]
Human activities and climate change threaten coldwater organisms in freshwater ecosystems by causing rivers and streams to warm, increasing the intensity and frequency of warm temperature events, and reducing thermal heterogeneity. Cold-water refuges are discrete patches of relat...
Comparison of two procedures for microplastics analysis in sediments based on an interlaboratory exercise.
(JOURNAL) [Published : Feb 01, 2023]
Microplastics (MP) are distributed throughout ecosystems and settle into sediments where they may threaten benthic communities; however, methods for quantifying MP in sediments have not been standardized. This study compares two methods for analyzing MP in sediments, including ex...
Concentrations of chemicals of emerging concern are mediated by seasonal hydrodynamics in an offshore marine environment.
(PRESENTATION) [Presented : Feb 10, 2023]
Many contaminants of emerging concern (CECs), including pharmaceuticals and personal care products, are distinct from legacy contaminants in their ability to travel readily in aqueous matrices, resulting in the common occurrence of CECs in aquatic system receiving point and nonpo...
Contrasting mercury contamination scenarios and site susceptibilities confound fish mercury burdens in Suriname, South America
(JOURNAL) [Published : Sep 12, 2023]
In Suriname, mercury (Hg) use has recently increased because of gold mining, which has put fish-reliant communities (e.g., Indigenous and Tribal) at risk of enhanced Hg exposure through the riverine fish these communities consume. To quantify how the magnitude of these risks chan...

Current US air pollution levels still harm sensitive tree species
(NEWSLETTER ARTICLE) [Published : Aug 21, 2023]
Air quality improvement has benefitted large portions of forests in the USA over the past 20 years. However, although terrestrial ecosystems are now better protected, sensitive species still experience harmful impacts, which could lead to biodiversity loss through shifts in fores...

Disentangling natural and anthropogenic effects on benthic macroinvertebrate assemblages in western US streams
(JOURNAL) [Published : Nov 09, 2023]
Stream macroinvertebrate assemblages are shaped by natural and human-related factors that operate through complex hierarchical pathways. Quantifying these relationships can support stream ecological assessment. We applied a structural equation modeling framework to evaluate hypot...
Distribution and Expansion of Alien Fish Species in the Karun River Basin, Iran
(JOURNAL) [Published : Oct 31, 2023]
We assessed the distribution of alien fishes in the Karun River Basin, Iran. Fish were collected from 39 sites during the November–December 2018 low-flow period. In total, 39 fish species from nine orders and 14 families were documented. Among these, 10 species were alien t...
EPA Office of Research & Development Initiatives to Monitor Environmental AMR and Model Risk
(PRESENTATION) [Presented : Mar 24, 2023]
Antimicrobial resistance (AMR) has been identified as one of the top medical issues worldwide, leading many countries to place greater emphasis on combating resistant bacteria through a multipronged, coordinated approach.  A consensus has emerged among the greater public hea...
