Quantifying fine sediment infiltration in spawning gravel used by Chinook salmon (Oncorhynchus tshawytscha) in the Sauk River Basin, Washington, 2018–21
Kristin L. Jaeger, Scott W. Anderson, Anya C. Leach, Scott T. Morris
2024, Scientific Investigations Report 2024-5077
Fine sediment can infiltrate into river substrate that salmonid fish species (Oncorhynchus spp.) use to spawn. High levels of sediment infiltration can increase egg-to-fry mortality, which corresponds to the period when salmonids are still residing in the subsurface gravels. This study quantifies fine sediment infiltration of Chinook salmon (Oncorhynchus tshawytscha)...
Comparison of water quality in shallow groundwater near agricultural areas in the Delaware Coastal Plain, 2014 and 2019
Alexander M. Soroka, Betzaida Reyes, Brandon Fleming, Michael Brownley
2024, Scientific Investigations Report 2024-5076
The State of Delaware has encouraged agricultural conservation practices to improve nutrient uptake by crops and mitigate nutrient transport to groundwater in the surficial aquifer. To study recent changes in groundwater quality, the U.S. Geological Survey and the Delaware Department of Agriculture (DDA) developed a network of shallow wells near...

Eric Leis, Sara Dziki, Emilie Blevins, Diane L. Waller, Jordan Richard, Susan Knowles, Tony Goldberg
2024, Invertebrate Biology (143)
Native freshwater mussel (Unionidae) mortality events have been occurring with increased frequency in recent decades, with few investigations into potential etiological agents. In the western United States, no surveys have been published regarding the bacteria associated with unionid mussels. Herein, we examine locations of known mussel mortality events in the...

Nathaniel P. Hitt, Karli M Rogers, Zachary A. Kelly
2024, Hydrobiology (3) 310-324
Salmonid fishes provide an important indicator of climate change given their reliance on cold water. We evaluated temporal changes in the density of stream-dwelling brook trout (Salvelinus fontinalis) from surveys conducted over a 36-year period (1988–2023) by the Maryland Department of Natural Resources in Eastern North America. Nonparametric trend...

Overcoming low detectability in snake conservation research: Case studies from the Southeast USA
John D. Willson, Jacquelyn C. Guzy, Andrew M. Durso
2024, Book chapter, Strategies for Conservation Success in Herpetology
Goals of conservation research include detecting and monitoring changes in abundance, understanding species interactions, detecting extinction events of imperiled species, and detecting colonization events and spread of non-native species. Achieving these goals is difficult or impossible when the target species is rarely encountered or when the number of individuals detected...
Effects of recent wildfires on giant sequoia groves were anomalous at millennial timescales: a response to Hanson et al.
Nathan L. Stephenson, David Nicolas Bertil Soderberg, Joshua A. Flickinger, Anthony C. Caprio, Adrian Das
2024, Fire Ecology (20)
BackgroundThe giant sequoia (Sequoiadendron giganteum [Lindley] Buchholz) of California’s Sierra Nevada recently suffered historically unprecedented wildfires that killed an estimated 13–19% of seed-bearing sequoias across their native range. Hanson et al. recently sought to characterize post-fire reproduction in two severely burned sequoia groves, but their two papers (1) inaccurately...
Brodifacoum isomer formulations with potentially lower risk to non-target wildlife
Barnett A. Rattner, Richard A. Erickson, Julia S. Lankton, Etienne Benoit, Virginie Lattard
2024, Conference Paper, Proceedings of the 31st vertebrate pest conference
Anticoagulant rodenticides (ARs) have a long history of successful use in controlling vertebrate pest and invasive species. Despite regulatory efforts to mitigate risk, non-target wildlife may be unintentionally exposed to ARs through various trophic pathways, and depending on dose, exposure can result in adverse effects and mortality. Second-generation ARs (SGARs)...

Travis L. Smith
2024, Scientific Investigations Report 2024-5081
The condition of surface water storage in lakes and impoundments is used as an index of drought in the Massachusetts drought management plan. The U.S. Geological Survey visited 28 of these lakes and impoundments at 14 single and multiple waterbody systems to evaluate their appropriateness for characterizing drought. The data...

Ramon C. Naranjo
2024, Report
Secchi depth measurements in Lake Tahoe have been collected at a Long-Term Profile (LTP) monitoring site since 1968. Periodic updates in Secchi trend analysis are needed to understand changes in the long-term record, changes in seasonal pattern, and to provide insight into the progress of restoration efforts in improving lake...

2024, JGR - Atmospheres (129)
The environmental effects of airborne micro- and nano-size plastic particles are poorly understood. Microscopy and chemical analyses of atmospherically deposited particles on snow surfaces at high elevation (2,865–3,690 m) in the Upper Colorado River basin (UCRB; Colorado Rocky Mountains) revealed the presence of black substances intimately associated with...
How to reduce the risks of introducing and spreading invasive species in a major disaster
National Invasive Species Council
2024, Report
Disaster impacts are exacerbated by invasive species, which are harmful, non-native organisms that can be introduced and spread by disasters, including disaster response and recovery operations. Mechanisms are available to reduce risks from invasive species in a disaster, but those mechanisms are rarely used because invasive species experts and emergency...

James Wood, Lee H. Dietterich, Douglas R. Leasure, Sarah Jantzi, Thomas Maddox, Seth J. Wenger, Jonathan Skaggs, Amy D. Rosemond, Mary Freeman
2024, Science of the Total Environment (954)
Land use influences surface water quality, often alleviating stoichiometric constraints on primary production and altering biogeochemical cycling. However, land use effects on nutrient content and potential trace metal accumulation in aquatic plants remain unclear, and high concentrations of metals and altered nutrient ratios could impact the health of herbivores and...

The Khonkho tephra: A large-magnitude volcanic eruption coincided with the rise of Tiwanaku in the Andes
Erik J. Marsh, Christopher Harpel, David Damby
2024, The Holocene (34) 1865-1874
We report a tephra deposit in the southern Lake Titicaca Basin, Bolivia, which was deposited by a major, previously unrecognized eruption sometime between AD 400 and 720. Archaeological data suggest these centuries were characterized by a substantial community migration to Tiwanaku, where social interaction networks gave birth to one of...
