2022, Book chapter, Tactical sciences for biosecurity in animal and plant systems
The goal of biosecurity is to minimize the risk of introduction and transmission of infectious diseases to people, animals, and plants. This is achieved by accurately identifying pathogens and instituting appropriate methods to prevent their introduction, reemergence, and/or spread. However, disease is dynamic, and biosecurity needs to continually change to...

2022, Scientific Reports (12)
Online social networks (OSNs) have become a powerful tool to study collective human responses to extreme events such as earthquakes. Most previous research concentrated on a single platform and utilized users’ behaviors on a single platform to study people’s general responses. In this study, we explore the characteristics of people’s...

James R. Holmquist, Lisamarie Windham-Myers
2022, Estuaries and Coasts (45) 1596-1614
Tidal wetlands provide myriad ecosystem services across local to global scales. With their uncertain vulnerability or resilience to rising sea levels, there is a need for mapping flooding drivers and vulnerability proxies for these ecosystems at a national scale. However, tidal wetlands in the conterminous USA are diverse with differing...

Bear diets and human-bear conflicts: Insights from isotopic ecology
Nereyda Falconi, Tomas A. Carlo, Todd K. Fuller, Stephen DeStefano, John F. Organ
2022, Mammal Review (52) 322-327
Bears, Ursidae, are considered omnivores, except for giant pandas Ailuropoda melanoleuca and polar bears Ursus maritimus. However, omnivory includes a wide range of dietary variation and trophic positions, making bear dietary ecology unclear. We inferred bear trophic positions from δ15N (‰) values and examined their correlation with diets reported in the literature, including...
High densities of conspecifics buffer native fish from negative interactions with an ecologically similar invasive
Casey A. Pennock, W. Carl Saunders, Phaedra E. Budy
2022, Biological Invasions (24) 1283-1297
Invasive species are a leading cause for native species declines, but it remains unclear whether maintenance of high native densities influence native persistence in freshwater systems. We designed complementary laboratory and field experiments to test whether high native cutthroat trout (Oncorhynchus clarkii) densities affect competition with invasive brown trout...
Tracking spatial regimes in animal communities: Implications for resilience-based management
Caleb Powell Roberts, Daniel R. Uden, Craig R. Allen, David G. Angeler, Larkin A. Powell, Brady W Allred, Matthew O. Jones, Jeremy D Maestas, Dirac Twidwell
2022, Ecological Indicators (136)
Spatial regimes (the spatial extents of ecological states) exhibit strong spatiotemporal order as they expand or contract in response to retreating or encroaching adjacent spatial regimes (e.g., woody plant invasion of grasslands) and human management (e.g., fire treatments). New methods enable tracking spatial regime boundaries via vegetation landcover data, and...
Typology development of earthquake displays in free-choice learning environments, to inform earthquake early warning education in the United States
Danielle F. Sumy, Mariah Ramona Jenkins, Sara K. McBride, Robert Michael deGroot
2022, International Journal of Disaster Risk Reduction (73)
Free-choice learning environments, such as museums, national parks, interpretive trails, and visitor centers, are trusted sources of information in their communities and support lifelong learning. Earthquake education in these spaces creates awareness of earthquake hazards and risk in areas where people live or visit and, in turn, may increase engagement in preparedness...

Scott D. George, Brian T. Duffy, Barry P. Baldigo, Damianos Skaros, Alexander J. Smith
2022, Journal of Great Lakes Research (48) 183-194
The lower 10 km of the Buffalo River, a tributary to Lake Erie, was designated as an Area of Concern (AOC) in 1987 through the Great Lakes Water Quality Agreement because sediment contamination and habitat alteration from past industrialization caused several Beneficial Use Impairments (BUIs). Extensive remediation efforts conducted between 2011 and...

Behavior of female adult Pacific lamprey (Entosphenus tridentatus) exposed to natural and synthesized odors
Mike Hayes, Mary L. Moser, Brian J. Burke, Aaron D. Jackson, Nicholas S. Johnson
2022, Journal of Fish and Wildlife Management (13) 94-105
Conservation and management of Pacific Lamprey Entosphenus tridentatus and other imperiled lamprey species could include the use of chemosensory cues to attract or repel migrating adults. For restoration programs, passage of adult lamprey at dams might be improved by using cues to help guide lamprey through fishway entrances. In contrast,...
Assessing effects of sediment delivery to coral reefs: A Caribbean watershed perspective
Caroline Rogers, Carlos E. Ramos-Scharron
2022, Frontiers in Marine Science (8)
Coral reefs in the western Atlantic and Caribbean are deteriorating primarily from disease outbreaks, increasing seawater temperatures, and stress due to land-based sources of pollutants including sediments associated with land use and dredging. Sediments affect corals in numerous ways including smothering, abrasion, shading, and inhibition of coral recruitment. Sediment delivery...

Thiamine status of lake trout in lake Ontario and its relation to diet after the colonization of round goby, 2005–2006
John D. Fitzsimons, Brian F. Lantry, Dale C. Honeyfield, Robert O’Gorman, Scott A. Rush, Shawn P. Sitar
2022, Journal of Great Lakes Research (48) 195-206
A predominance of alewives (Alosa pseudoharengus), a species having high thiaminase activity, in Lake Ontario lake trout (Salvelinus namaycush) diets, has been related to thiamine deficiency in lake trout eggs during 1994–2004. The late 1990s invasion by round goby (Neogobius melanostomus), that...
Modeling subsurface performance of a geothermal reservoir using machine learning
Dmitry Duplyakin, Koenraad F Beckers, Drew L. Siler, Michael J. Martin, Henry E. Johnston
2022, Energies (15)
Geothermal power plants typically show decreasing heat and power production rates over time. Mitigation strategies include optimizing the management of existing wells—increasing or decreasing the fluid flow rates across the wells—and drilling new wells at appropriate locations. The latter is expensive, time-consuming, and subject to many engineering...
