2024, Bulletin of Volcanology (86)
The unprecedented 2018 summit collapse at Kīlauea and subsequent 2020–2021 eruption within the newly deepened Halema‘uma‘u Crater provide an unparalleled opportunity to understand how collapse events impact a volcano’s shallow reservoir system and magmatic processes. Glass and olivine from tephra ejected by lava fountains and several...

The deep sea is the largest biome on earth, but one of the least studied despite its critical role in global carbon cycling and climate buffering. Deep-sea organisms largely rely on particulate organic matter from the surface ocean for energy –...
Deposited sediment influences occurrence of functional traits of stream fishes
Mallory Hirschler, Amy M. Villamagna, Paul L. Angermeier, Eric Laflamme
2024, Ecology of Freshwater Fish (33)
To better understand stream-fish sensitivity to fine sediment, we documented assemblage-wide responses by selected traits along a sedimentation gradient. We then discuss the management implications of these ‘dose–response’ relations in the contexts of biotic assessments and conservation of sediment-sensitive species. We identified a spatial gradient in sediment deposition among streams...
Predicting redox conditions in groundwater at a national scale using random forest classification
Anthony J. Tesoriero, Susan Wherry, Danielle Dupuy, Tyler D. Johnson
2024, Environmental Science and Technology (58) 5079-5092
Redox conditions in groundwater may markedly affect the fate and transport of nutrients, volatile organic compounds, and trace metals, with significant implications for human health. While many local assessments of redox conditions have been made, the spatial variability of redox reaction rates makes the determination of redox conditions at regional...
Diurnal habitat selection and survival of elk neonates
James W. Pitman, James W. Cain III, William R. Gould, Nicole M. Tatman, Stewart G. Liley
2024, Southwestern Naturalist (67) 205-215
Natural selection should favor development of behaviors that increase survival, including juvenile survival. Habitat characteristics (e.g., hiding cover, forage quality and availability), maternal habitat selection, and microhabitat selection by the calf may influence elk (Cervus canadensis) calf survival and recruitment. We assessed diurnal microhabitat selection of bed sites by elk...

Melissa Moulton, Joseph B. Zambon, Zuo Xue, John C. Warner, Daoyang Bao, Dongxiao Yin, Zafer Defne, Ruoying He, Christie Hegermiller
2024, Journal of Geophysical Research: Oceans (129)
Extreme precipitation during Hurricane Florence, which made landfall in North Carolina in September 2018, led to breaches of hog waste lagoons, coal ash pits, and wastewater facilities. In the weeks following the storm, freshwater discharge carried pollutants, sediment, organic matter, and debris to the coastal ocean, contributing...

Making phase-picking neural networks more consistent and interpretable
Yongsoo Park, Brent G. Delbridge, David R. Shelly
2024, The Seismic Record (4) 72-80
Improving the interpretability of phase‐picking neural networks remains an important task to facilitate their deployment to routine, real‐time seismic monitoring. The popular phase‐picking neural networks published in the literature lack interpretability because their output prediction scores do not necessarily correspond with the reliability of phase picks and can even be...

Karl Veggerby, Mark David Scheuerell, Beth Sanderson, Peter Kiffney, Bridget Ferriss
2024, Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science (16)
ObjectiveOyster reefs across North America have declined precipitously over the past 140 years. In Washington State, Olympia oyster Ostrea lurida reefs historically provided water filtration and nearshore structural habitat for fishes and invertebrates, but this species is now functionally extinct across its historical range. In place of these naturally...

Rising water temperature in rivers: Ecological impacts and future resilience
Matthew F. Johnson, Lindsey K. Albertson, Adam C. Algar, Stephen J. Dugdale, Patrick Edwards, Judy England, Christopher Gibbins, So Kazama, Daisuke Komori, Andrew Maccoll, Eric Arthur Scholl, Robert Wilby, Fabio de Oliveira Roque, Paul F. Wood
2024, WIREs Water (11)
Rising water temperatures in rivers due to climate change are already having observable impacts on river ecosystems. Warming water has both direct and indirect impacts on aquatic life, and further aggravates pervasive issues such as eutrophication, pollution, and the spread of disease. Animals can survive higher temperatures through physiological and/or...

Caleb A. Aldridge, Michael E. Colvin
2024, Ecological Solutions and Evidence (5)
In natural resource and environmental management, well-written objectives are critical for effective decision-making and the achievement of desired outcomes. This article aims to improve practitioners' ability to identify and write SMART (Specific, Measurable, Achievable, Relevant, Time-bound) objectives for natural resource and environmental management.We differentiate between research and management objectives, define each SMART criterion,...

Wild waterfowl are natural hosts of avian influenza viruses (AIVs), are often abundant near poultry farms, and have been linked to outbreaks of AIVs in...
Exploring landscape and geologic controls on spatial patterning of streambank groundwater discharge in a mixed land use watershed
Kevin E. Jackson, Eric M. Moore, Ashley M. Helton, Adam B. Haynes, Janet R. Barclay, Martin A. Briggs
2024, Hydrological Processes (38)
Preferential groundwater discharge features along stream corridors are ecologically important at local and stream network scales, yet we lack quantification of the multiscale controls on the spatial patterning of groundwater discharge. Here we identify physical attributes that best explain variation in the presence and...

Natalia Malinowski, Matthew J. Morgan, Jason Wylie, Tom Walsh, Sergio Domingos, Suzanne Metcalfe, Anna H. Kaksonen, Elliott Barnhart, Rebecca C. Mueller, Brent M. Peyton, Geoffrey J. Puzon
2024, Water Research (254)
Naegleria fowleri has been detected in drinking water distribution systems (DWDS) in Australia, Pakistan and the United States and is the causative agent of the highly fatal disease primary amoebic meningoencephalitis. Previous small scale field studies have shown that Meiothermus may be a potential biomarker for N. fowleri. However,...
Extent and duration of cold-water areas associated with side channels and tributaries of the lower Yakima River, Washington, September 2018–20
Richard W. Sheibley, Marcella Appel, Rachel Little, James R. Foreman
2024, Scientific Investigations Report 2023-5140
Previous work on the lower Yakima River, Washington (downstream from Union Gap), has identified several cold-water areas that could be thermal refuges for migrating salmonids. These cold-water areas are characterized by small tributaries that are typically cooler than the main-stem river during summer months (June–August). Twenty-seven temperature sensors were deployed...
