2024, Journal of Great Lakes Research (50)
To better understand the primary drivers of the thermal regime in a Great Lakes estuary, and their implications for local biota, water temperature variations in the Milwaukee Estuary of Lake Michigan were studied between July and October of 2019 using a network of 25 sensors at 18 locations. Like Lake...

Ana Garcia-Ceballos, Ge Jin, Timothy Collett, Sukru Merey, Seth S. Haines
2024, SPE Journal (29) 5804-5819
Well integrity monitoring has always been a critical component of subsurface oil and gas operations. Distributed fiber-optic sensing is an emerging technology that shows great promise for monitoring processes, both in boreholes and in other settings. In this study, we present a case study of using distributed temperature sensing (DTS)...
Parasite abundance-occupancy relationships across biogeographic regions: Joint effects of niche breadth, host availability and climate
Konstans Wells, Jeffrey A Bell, Alan Fecchio, Sergei V. Drovetski, Spencer C Galen, Shannon Hackett, Holly L Lutz, Heather Skeen, Gary Voelker, Wanyoike Wamiti, Jason D Weckstein, Nicholas J. Clark
2024, Journal of Biogeography (52) 55-65
Changing biodiversity and environmental conditions may allow multi-host pathogens to spread among host species and affect prevalence. There are several widely acknowledged theories about mechanisms that may influence variation in pathogen prevalence, including the controversially debated dilution effect and abundance-occupancy relationship hypotheses. Here, we explore such abundance-occupancy relationships for unique...
The feasibility of using national-scale datasets for classifying wetlands in Arizona with machine learning
Christopher E. Soulard, Jessica J. Walker, Britt Windsor Smith, Jason R. Kreitler
2024, Earth Surface Processes and Landforms (49) 4632-4649
The advent of machine learning techniques has led to a proliferation of landscape classification products. These approaches can fill gaps in wetland inventories across the United States (U.S.) provided that large reference datasets are available to develop accurate models. In this study, we tested the feasibility of expediting the classification...
The U.S. Geological Survey National Streamgage Network—2023
Brian E. McCallum
2024, General Information Product 242
The U.S. Geological Survey (USGS) operated 11,850 continuous surface-water monitoring locations (streamgages) across the United States in 2023. The streamgages provide information on river height and streamflow, typically at 15-minute intervals. This information is then made available to everyone, most of it delivered nearly in realtime on the USGS National...

Ricardo A. Chávez Montesa, Mousumi A. Mary, Rakib H. Rashel, Mohamed Fokar, Luis Herrera-Estrella, Damar Lopez-Arredondo, Reynaldo Patino
2024, Science of the Total Environment (954)
Growth of the toxic alga Prymnesium parvum is hormetically stimulated with environmentally relevant concentrations of glyphosate. The mechanisms of glyphosate hormesis in this species, however, are unknown. We evaluated the transcriptomic response of P. parvum to glyphosate at concentrations that stimulate maximum growth and where growth is not different from control values, the zero-equivalent...

David E. Rundio, Brian C. Spence, Dorothy M. Chase, Carl O. Ostberg
2024, North American Journal of Fisheries Management (44) 1167-1182
ObjectiveDebris flows are among the most extreme disturbances to streams and are predicted to become more frequent under climate change. We assessed the response of steelhead Oncorhynchus mykiss (anadromous Rainbow Trout)/Rainbow Trout (hereafter, collectively referred to as O. mykiss) and Coastrange Sculpin Cottus aleuticus populations to major postfire debris...

M.N. Mansbach, T.V. Kizovski, E. L. Scheller, T. Bosak, L. Mandon, B. Horgan, R.C. Wiens, C.D.K. Herd, S. Sharma, J.R. Johnson, Travis S.J. Gabriel, O. Forni, B.P. Weiss
2024, Journal of Geophysical Research: Planets (129)
Although Mars today does not have a core dynamo, magnetizations in the Martian crust and in meteorites suggest a magnetic field was present prior to 3.7 billion years (Ga) ago. However, the lack of ancient, oriented Martian bedrock samples available on Earth has prevented accurate estimates of...
Physics-based forecasts of eruptive vent locations at calderas
Lorenzo Mantiloni, Eleanora Rivalta, Kyle R. Anderson, Timothy W. Davis, Luigi Passarelli
2024, Journal of Geophysical Research: Solid Earth (129)
Constraining stresses in the Earth's crust in volcanic regions is critical for understanding many mechanical processes related to eruptive activity. Dike pathways, in particular, are shaped by the orientation of principal stress axes. Therefore, accurate models of dike trajectories and future vent locations rely on accurate estimates...

Jessica Marie Rieder, Eliane Jemmi, Margaret Hunter, Irene Adrian-Kalchhauser
2024, Environmental DNA (6)
Ecologists, biologists, and conservation scientists are increasingly interested in the use of environmental DNA (eDNA) data for research and potentially decision-making. While commercial DNA extraction kits are typically user-friendly and accessible, they may fail to deliver the desired results with inherently complex eDNA samples,...

Joseph Vantassel, Makbule Ilgac, Adda Athanasopoulos Zekkos, Alan Yong, Behzad Hassani, Antony Martin
2024, Bulletin of the Seismological Society of America (114) 3078-3092
We consider the similarities and differences between earthquake and microtremor horizontal‐to‐vertical spectral ratios (eHVSR and mHVSR, respectively) using a dataset of 161 sites in southern California. Quantitative comparisons are made in terms of the eHVSR and mHVSR lognormal median curves, as well as the frequencies and amplitudes associated with the...
Agricultural tile drains increase the susceptibility of streams to longer and more intense streamflow droughts
Seth Adelsperger, Darren Ficklin, Scott Robeson, Margaret Ann Zimmer, John C. Hammond, Damon M. Hall, J.P. Gannon
2024, Environmental Research Letters (19)
Streamflow droughts are receiving increased attention worldwide due to their impact on the environment and economy. One region of concern is the Midwestern United States, whose agricultural productivity depends on subsurface pipes known as tile drains to improve trafficability and soil conditions for crop growth. Tile drains accomplish this by...

Thomas J. Devries, John A. Barron, Diana Ochoa, Kristen McDougall
2024, Stratigraphy (21) 189-224
The East Pisco Basin, occupying the coastal plain of Peru between 13°S and 16°S, is widely known for its extensive Eocene to Quaternary biosiliceous deposits and excellent preservation of fossil marine vertebrates. Biochronologic studies published over the past 35 years record a hiatus of about 13 million years (*32–19 Ma)...

Dryland ecosystems cover 40% of our planet's land surface, support billions of people, and are responding rapidly to climate and land use change. These expansive systems also dominate core aspects of Earth's climate, storing and exchanging vast amounts of water, carbon, and energy with the atmosphere. Despite their indispensable ecosystem...

2024, Journal of South American Earth Sciences (148)
The Laguna del Maule (LdM) volcanic field, which surrounds the 54-km2 lake of that name, covers ∼500 km2 of mountainous glaciated terrain with Quaternary lavas and tuffs that extend 40 km westward from the Argentine frontier and 30 km north-south from the Río Campanario to Laguna Fea. Complementing recent investigations of postglacial volcanism...
Modeling the effects of temperature and limiting nutrients on the competition of an invasive floating plant, Pontederia crassipes, with submersed vegetation in a shallow lake
Linhao Xu, Don DeAngelis
2024, Plants (13)
The potential for a non-native plant species to invade a new habitat depends on broadscale factors such as climate, local factors such as nutrient availability, and the biotic community of the habitat into which the plant species is introduced. We developed a spatially explicit model to assess the risk...
