Anticoagulant rodenticides (ARs) are used to control pest rodent species but can result in secondary poisoning of non-target animals, especially raptors. In the present study, differences in AR sensitivity among avian species were evaluated by comparing in vivo warfarin pharmacokinetics and effects, measuring cytochrome P450s (CYPs) expression involved in AR metabolism, and...

Jody Brae Wycech, Daniel Clay Kelly, Reinhard Kozdon, Akizumi Ishida, Kouki Kitajima, Howard J. Spero, John W. Valley
2024, Rapid Communications in Mass Spectrometry (38)
Rationale: The use of secondary ion mass spectrometry (SIMS) to perform micrometer-scale in situ carbon isotope (δ13C) analyses of shells of marine microfossils called planktic foraminifers holds promise to explore calcification and ecological processes. The potential of this technique, however, cannot be realized without comparison to traditional whole-shell δ13C values measured by...

Global changes in climate and land use are threatening natural ecosystems, biodiversity, and the ecosystem services people rely on. This is why it is necessary to track and monitor spatiotemporal change at a level of detail that can inform science, management, and policy development. The current constellation of multiple Landsat and Sentinel-2 satellites...
Determination and prediction of micro scale rare earth element geochemical associations in mine drainage treatment wastes
Benjamin C. Hedin, Mengling Y. Stuckman, Charles A. Cravotta III, Christina L. Lopano, Rosemary C. Capo
2024, Chemosphere (346)
Acid mine drainage (AMD) has been proposed as a novel source of rare earth elements (REE), a group of elements that includes critical metals for clean energy and modern technologies. REE are sequestered in the Fe–Al–Mn-rich precipitates produced during the treatment of AMD. These AMD solids are typically managed...

Giovanna Monticelli, Joseph Bisesi Jr., Jason Tyler Magnuson, Daniel Schlenk, Carlos Zarza, David Peggs, Daniela Pampanin
2024, Aquaculture (580)
Although concerns about the impacts of antibiotics in aquatic organisms are reported worldwide, the potential adverse effects on fish gut microbial communities and fish health are still not well known. In this study, we investigated the effects of florfenicol (FFC) on the gut microbiome and gastrointestinal (GIT) gene expression in juvenile Atlantic salmon (Salmo salar). Three doses...

James Meldrum, Patricia A. Champ, Hannah Brenkert-Smith, Christopher M. Barth, Abby Elizabeth McConnell, Carolyn Wagner, Colleen Donovan
2024, Ecological Economics (216) 108041
Public agencies and organizations often deliver financial assistance through cost sharing, in which recipients contribute some portion toward total costs. However, cost sharing might raise equity concerns if it reduces participation among populations with lower incomes. Here, we revisit a past study using a...

A major source of toxic per- and polyfluoroalkyl substances (PFAS) is aqueous film-forming foams (AFFF) used in firefighting and training at airports and military installations, however, PFAS have many additional sources in consumer products and industrial processes. A field study was conducted on fish tissues from three reaches of the Columbia...
Recent, widespread nitrate decreases may be linked to persistent dissolved organic carbon increases in headwater streams recovering from past acidic deposition
Kevin Alexander Ryan, Gregory B. Lawrence
2024, Science of the Total Environment (906)
Long-term monitoring of water quality responses to natural and anthropogenic perturbation of watersheds informs policies for managing natural resources. Dissolved organic carbon (DOC) and nitrate (NO3−) in streams draining forested landscapes provide valuable information on ecosystem function due to their biogeochemical reactivity and solubility in water....
Analyzing spatial distributions and alignments of pitted cone features in Utopia Planitia on Mars
Mackenzie M. Mills, Alfred S. McEwen, Amanda N. Hughes, Ji-Eun Kim, Chris Okubo
2024, Icarus (408)
Martian geomorphology and surface features provide links to understanding past geologic processes such as fluid movement, local and regional tectonics, and feature formation mechanisms. Pitted cones are common features in the northern plains basins of Mars. They have been proposed to have formed from upwelling volatile-rich fluids, such as magma or water-sediment slurries. In...

Rongrong Xuan, Xiaojian Qiu, Jiazhen Wang, Shai Liu, Jason Tyler Magnuson, Bentuo Xu, Wenhui Qui, Chunmiao Zheng
2024, Journal of Hazardous Materials (461)
Perfluorooctane sulfonamide (PFOSA), a typical perfluorooctane sulfonate precursor (PreFOS), has been detected in the aquatic environment globally. However, the effects of PFOSA at levels measured in the environment have not been well characterized in aquatic organisms. In this study, we evaluated the transcriptional, biochemical, histopathological, and morphological...

James Willacker, Collin Eagles-Smith, Jim Chandler, Jesse Naymik, Ralph Myers, David P. Krabbenhoft
2023, Environmental Science & Technology
Impoundment is among the most common hydrologic alterations with impacts on aquatic ecosystems that can include effects on mercury (Hg) cycling. However, landscape-scale differences in Hg bioaccumulation between reservoirs and other habitats are not well characterized nor are the processes driving these differences. We examined total Hg (THg) concentrations of...

Selection of microhabitats, plants, and plant parts eaten by a threatened tortoise: Observations during a superbloom
W. Bryan Jennings, Kristin H. Berry
2023, Frontiers in Amphibian and Reptile Science (1)
Populations of the threatened desert tortoise (Gopherus agassizii) continue to decline throughout the geographic range, in part because of degraded and fragmented habitats in the Mojave and western Sonoran deserts. The species is herbivorous and highly selective in choice of plant species. To increase options for recovery, we analyzed behaviors,...
