Rebecca M. Kreiling, Lynn A. Bartsch, Patrik Mathis Perner, Kenna Jean Breckner, Tanja N. Williamson, James M. Hood, Nathan F. Manning, Laura T. Johnson
2024, Journal of Great Lakes Research (50)
Management efforts to reduce cyanobacterial harmful algal blooms (cHABs) in the Great Lakes have focused on decreasing tributary inputs of phosphorus (P). Recent research has indicated that reduction of both P and nitrogen (N) can lessen cHABs severity. Microbially mediated N cycling in streambed sediment may reduce N riverine loads,...

Noise constraints on global body‐wave measurement thresholds
Adam T. Ringler, David C. Wilson, Paul S. Earle, William L. Yeck, David B. Mason, Justin T. Wilgus
2024, Bulletin of the Seismological Society of America (114) 1765-1776
Intermediate sized earthquakes (≈M4–6.5) are often measured using the teleseismic body‐wave magnitude (𝑚b). 𝑚b measurements are especially critical at the lower end of this range when teleseismic waveform modeling techniques (i.e., moment tensor analysis) are difficult. The U.S. Geological Survey National Earthquake Information Center (NEIC) determines the location...

Jessica A. Thompson Jobe, Richard W. Briggs, Ryan D. Gold, Laurel Bauer, Camille Collett
2024, Bulletin of the Seismological Society of America (114) 1920-1940
The ~300-km-long eastern Tennessee seismic zone (ETSZ), USA, is the second-most seismically active region east of the Rocky Mountains. Seismicity generally occurs below the Paleozoic fold-and-thrust belt within the Mesoproterozoic basement, at depths of 5–26 km, and earthquake magnitudes during the instrumental record have been moment magnitude (Mw)≤4.8. Evidence of...

2024, Proceedings of the AAAI Conference on Artificial Intelligence (38) 22087-22095
Accurate prediction of water quality and quantity is crucial for sustainable development and human well-being. However, existing data-driven methods often suffer from spatial biases in model performance due to heterogeneous data, limited observations, and noisy sensor data. To overcome these challenges, we propose Fair-Graph, a novel graph-based recurrent neural network...

Mousumi A. Mary, Shisbeth Tabora-Sarmiento, Sarah Nash, Gregory D. Mayer, Jordan Crago, Reynaldo Patino
2024, Water (16)
Prymnesium parvum is a harmful alga found in brackish waters worldwide whose toxins can be lethal to aquatic organisms. Established field methods to control blooms of this species, however, are unavailable. Earlier studies showed that various extracts of giant reed (Arundo donax) can suppress P. parvum growth and that ellipticine,...

Lucas Berio Fortini, Lauren R. Kaiser, Curtis Daehler, James D. Jacobi, Monica Dimson, Thomas W Gillespie
2024, Biological Invasions (26) 1827-1843
The spread of ecosystem modifying invasive plant (EMIP) species is one of the largest threats to native ecosystems in Hawaiʻi. However, differences in niche characteristics between Hawaiʻi’s isolated insular environment and the wider global distribution of these species have not been carefully examined. We used species distribution modeling (SDM) methods...

Megan C. Milligan, Peter S. Coates, Shawn T. O’Neil, Brianne E. Brussee, Michael P. Chenaille, Derek Friend, Kathleen Steele, Justin R. Small, Timothy S. Bowden, Arlene D. Kosic, Katherine Miller
2024, Open-File Report 2024-1018
Executive SummaryGreater sage-grouse populations (Centrocercus urophasianus; hereafter sage-grouse) are threatened by a suite of disturbances and anthropogenic factors that have contributed to a net loss of sagebrush-dominant shrub cover in recent decades. Declines in sage-grouse populations are largely linked to habitat loss across their range. A key component of conservation...
Seismic attenuation and stress on the San Andreas Fault at Parkfield: Are we critical yet?
Luca Malagnini, Robert M. Nadeau, Thomas E. Parsons
2024, Frontiers in Earth Science (12)
The Parkfield transitional segment of the San Andreas Fault (SAF) is characterized by the production of frequent quasi-periodical M6 events that break the very same asperity. The last Parkfield mainshock occurred on 28 September 2004, 38 years after the 1966 earthquake, and after the segment showed a ∼22 years average...

Camila Gaido-Lassarre, Kees Nederhoff, Curt D. Storlazzi, Borja Reguero, Michael W. Beck
2024, Journal of Marine Science & Engineering (198)
Coastal flooding affects low-lying communities worldwide and is expected to increase with climate change, especially along reef-lined coasts, where wave-driven flooding is particularly prevalent. However, current regional modeling approaches are either insufficient or too computationally expensive to accurately assess risks in...

2024, Scientific Investigations Report 2024-5017
Groundwater development, mainly for large-scale irrigation, has increased substantially in the Harney Basin of southeastern Oregon since 2010. Concurrently, some areas of the basin experienced groundwater-level declines of more than 100 feet, and some shallow wells have gone dry. The Oregon Water Resources Department has limited new groundwater development in...

Managing ecosystems with resist-accept-direct (RAD)
Byron K. Williams, Ellie Brown
2024, Methods in Ecology and Evolution (15) 796-805
In recent years considerable interest has been generated in a new approach known as resist–accept–direct, or RAD, for managing ecosystems in the face of climate change. Under RAD, strategic responses to climate change are described in terms of three broad categories: resisting climate transformation, accepting the transformation and continuing to...

Gavin N. Saari, Samreen Siddiqui, Susanne M. Brander
Samreen Siddiqui, Susanne M. Brander, editor(s)
2024, Book chapter, Aquatic ecotoxicology
Human populations have utilized heavy metals and persistent organic pollutants for their physiochemical properties in industrial, agricultural, and consumer goods for decades. Limited knowledge on their persistence and toxicological effects has resulted in organisms being exposed to some of the most problematic compounds ever generated by humans. Although overlap in...

Raphael M. Kudela, David B. Senn, Emily T. Richardson, Keith Bouma-Gregson, Brian A. Bergamaschi, Lawrence Sim
2024, Remote Sensing (16)
A massive bloom of the raphidophyte Heterosigma akashiwo occurred in summer 2022 in San Francisco Bay, causing widespread ecological impacts including events of low dissolved oxygen and mass fish kills. The rapidly evolving bloom required equally rapid management response, leading to the use of near-real-time image analysis of chlorophyll from the...

This study introduces a novel and comprehensive framework for...
White-tailed deer detection rates increase when coyotes are present
Hannah L. Clipp, Sarah M. Pesi, Madison L. Miller, Laura C. Gigliotti, Brett P. Skelly, Christopher T. Rota
2024, Ecology and Evolution (14)
Predator species can indirectly affect prey species through the cost of anti-predator behavior responses, which may involve shifts in occupancy, space use, or movement. Quantifying the various strategies implemented by prey species to avoid adverse interactions with predators can lead to a better understanding of potential population-level repercussions. Therefore, the...
