Justin Bopp, Travis O. Brenden, Matthew D. Faust, Christopher Vandergoot, Richard Kraus, James Roberts, Lucas Nathan
2023, Biological Invasions (25) 2439-2459
Understanding the timing and drivers of migration can be beneficial for improving response efforts aimed at reducing invasive species densities. Efforts by management agencies to remove grass carp (Ctenopharyngodon idella), an invasive species to the Laurentian Great Lakes, have been ongoing in Lake Erie tributaries since 2018. To bolster efforts,...
Fusing geophysical and remotely sensed data for observing overwash occurrence, frequency, and impact
Nicholas Enwright, P. Soupy Dalyander, Robert L Jenkins, Elizabeth S. Godsey, Spencer J. Stelly
2023, Conference Paper, The proceedings of the coastal sediments 2023
Overwash is an important process that enables a barrier island to migrate landward to adapt to rising sea levels but can also impact vegetated areas and create coastal hazards for populated barrier islands. Our overall objectives were to hindcast overwash events from September 2008 to November 2009 and assess whether...
Assessing arthropod diversity metrics derived from stream environmental DNA: Spatiotemporal variation and paired comparisons with manual sampling
Aaron W. Aunins, Sara J. Mueller, Jennifer A. Fike, Robert S. Cornman
2023, PeerJ (11)
BackgroundBenthic invertebrate (BI) surveys have been widely used to characterize freshwater environmental quality but can be challenging to implement at desired spatial scales and frequency. Environmental DNA (eDNA) allows an alternative BI survey approach, one that can potentially be implemented more rapidly and cheaply than traditional methods.MethodsWe evaluated...

Benjamin Patrick Magnin, Yvette Kuiper, Eric D. Anderson
2023, Tectonics (42)
Structures associated with Ediacaran-Ordovician alkaline magmatism and the timing of rare earth element (REE) mineralization in the Wet Mountains, CO, were analyzed using field, geophysical, and U-Th-Pb isotope methods to interpret their tectonic setting in the context of previously proposed rift models. The Wet Mountains are known...
Assessing tradeoffs between current and desired vegetation condition in a National Park using historical maps and high resolution lidar data
John A. Young, Carolyn Mahan
2023, Restoration Ecology (31)
In the United States, National Park Service Civil War battlefield units are managed for both historical accuracy (i.e., to represent landscape conditions at the time of the conflict for historical interpretation), and for natural resource protection. However, managing for both goals can create conflicts as many battlefields were largely open...

Bivalve effects on the food web supporting delta smelt—A spatially intensive study of bivalve recruitment, biomass, and grazing rate patterns with varying freshwater outflow in 2019
Emily L. Zierdt Smith, Kelly H. Shrader, Janet K. Thompson, Francis Parchaso, Karen Gehrts, Elizabeth Wells
2023, Open-File Report 2022-1102
Phytoplankton are an important and limiting food source in the Sacramento-San Joaquin Delta and San Francisco Bay. The decline of phytoplankton biomass is one potential factor in the decline of the protected Hypomesus transpacificus (delta smelt) and other pelagic organisms. The bivalves Corbicula fluminea and Potamocorbula amurensis (hereafter C. fluminea...

Pandemic-driven changes in the nearshore non-commercial fishery in Hawai'i: Catch photos posted to social media capture changes in fisher behavior
Timothy B. Grabowski, Michelle E. Benedum, Andrew Curley, Cole Dill-De, Michelle L. Shuey
2023, PeerJ (11)
Using social media, we collect evidence for how nearshore fisheries are impacted by the global COVID-19 pandemic in Hawai’i. We later confirm our social media findings and obtain a more complete understanding of the changes in nearshore non-commercial fisheries in Hawai’i through a more conventional approach—speaking directly with fishers. Resource...

Land cover differentially affects abundance of common and rare birds
Kristin P. Davis, Paul C. Banko, Liba Pejchar
2023, Global Change Biology (29) 2999-3009
While rare species are vulnerable to global change, large declines in common species (i.e., those with large population sizes, large geographic distributions, and/or that are habitat generalists) also are of conservation concern. Understanding if and how commonness mediates species' responses to global change, including...

Drinking water supplies across the United States have been contaminated by firefighting and fire-training activities that use aqueous film-forming foams (AFFF) containing per- and polyfluoroalkyl substances (PFAS). Much of the AFFF is manufactured using electrochemical fluorination by 3M. Precursors with six perfluorinated...
Compensatory recruitment unlikely in high-elevation amphibian populations challenged with disease
Bennett Hardy, Erin L. Muths, Bradley Lambert, Scott C. Schneider, W. C. Funk, Larissa L. Bailey
2023, Journal of Applied Ecology (60) 121-131
Understanding the causes of population variation in host response to disease, and the mechanisms of persistence, can serve as vital information for species conservation. One such mechanism of population persistence that has gained support is the demographic process of compensatory recruitment. Host populations may persist by increasing recruitment to...
