David R. Smith, H. Jane Brockmann, Ruth H. Carmichael, Eric M. Hallerman, W.M. Watson, Jaime Zaldivar-Rae
2023, Aquatic Conservation: Marine and Freshwater Ecosystems
According to an International Union for Conservation of Nature (IUCN) Red List assessment (RLA), the American horseshoe crab (Limulus polyphemus), an iconic coastal species, is at risk of extirpation in some regions within its range where small and vulnerable populations occur. However, the RLA does not consider future status...
Movement and behavioral states of common carp (Cyprinus carpio) in response to a behavioral deterrent in a navigational lock
Maggie Jo Raboin, John Plumb, Matthew Sholtis, David Smith, P. Ryan Jackson, Jose Rivera, Cory D. Suski, Aaron R. Cupp
2023, Movement Ecology (11)
Freshwater ecosystems are some of the most affected by biological invasions due, in part, to the introduction of invasive carp worldwide. Where carp have become established, management programs often seek to limit further range expansion into new areas by reducing their movement through interconnected rivers and waterways. Lock and dams...

2023, Journal of Environmental Management (343)
Environmental DNA (eDNA) sampling provides sensitive early detection capabilities for recently introduced taxa. However, natural resource managers struggle with how to integrate eDNA results into an early detection rapid response program because positive eDNA detections are not always indicative of...

2023, Conservation Biology
Biodiversity and human well-being strategies are only as good as the set of ideas that people think about. This article evaluates value-focused thinking (VFT), a framework that focuses on creating objectives and strategy ideas that are responsive to the objectives. We performed a proof-of-concept study of VFT on six planning...

Multispecies approaches to status assessments in support of endangered species classifications
Daniel Bruce Fitzgerald, Mary Freeman, Kelly O. Maloney, John A. Young, Amanda E. Rosenberger, David C. Kazyak, David R. Smith
2022, Conservation Science and Practice (4)
Multispecies risk assessments have developed within many international conservation programs, reflecting a widespread need for efficiency. Under the United States Endangered Species Act (ESA), multispecies assessments ultimately lead to species-level listing decisions. Although this approach provides opportunities for improved efficiency, it also risks overwhelming or biasing the assessment process and...
Using structured decision making to evaluate potential management responses to detection of dreissenid mussel (Dreissena spp.) environmental DNA
Adam J. Sepulveda, David R. Smith, Katherine M O'Donnell, Nathan Owens, Brittany White, Catherine A. Richter, Christopher M. Merkes, Skylar Wolf, Mike Rau, Matthew Neilson, Wesley Daniel, Christine E. Dumoulin, Margaret Hunter
2022, Management of Biological Invasions (13) 344-368
Environmental (e)DNA tools are sensitive and cost-effective for early detection of invasive species. However, the uncertainty associated with the interpretation of positive eDNA detections makes it challenging to determine appropriate natural resource management responses. Multiple sources of error can give rise to positive detections of eDNA in a sample when...
Performance of a carbon dioxide injection system at a navigation lock to control the spread of aquatic invasive species
Thomas J. Zolper, David Smith, P. Ryan Jackson, Aaron R. Cupp
2022, Journal of Environmental Engineering (148)
Natural resource agencies need effective strategies to control the spread of aquatic invasive species (AIS) such as invasive fish, which can expand their range using rivers as hydrological pathways to access new areas. Lock and dam structures within major rivers are prospective locations to deploy techniques, such...

Justin J. Bopp, Matthew Sclafani, Michael G. Frisk, Kim McKown, Catherine Zeigler, David R. Smith, Robert Cerrato
2021, Ecosphere (12)
Identifying mechanisms that underpin animal migration patterns and examining variability in space use within populations is crucial for understanding population dynamics and management implications. In this study, we quantified the migration rates, seasonal changes in migratory connectivity, and residency across population demographics (age and sex) to...
Adaptive two-stage inverse sampling design to estimate density, abundance, and occupancy of rare and clustered populations
Mohammad Salehi, David R. Smith
2021, PLoS ONE (16)
Sampling rare and clustered populations is challenging because of the effort required to find rare units. Heuristically, a practitioner would prefer to discontinue sampling in areas where rare units of interest are apparently extremely sparse or absent. We take advantage of the characteristics of inverse sampling...

David Smith, Amélie Y. Davis, Claudia Hitaj, Dan Hellerstein, Amanda Preslicka, Emma Kirkpatrick, David M. Mushet, Eric Lonsdorf
2021, Environmental Research Letters (16)
Decreased availability of forage, as well as increased pesticide exposure, are important factors in the decline of honey bee health. Here, we isolate land cover transitions and their effect on honey production at 160 commercial apiaries in the Northern Great Plains. We found that land cover changes from 2008 to...

C. Amanda Garcia, Keith J. Halford, Philip M. Gardner, David W. Smith
2021, Scientific Investigations Report 2021-5021
Understanding groundwater flow and pumping effects near pending mining operations requires accurate subsurface hydraulic characterization.

2021, Nature Communications (12)
Water radiolysis continuously produces H2 and oxidized chemicals in wet sediment and rock. Radiolytic H2 has been identified as the primary electron donor (food) for microorganisms in continental aquifers kilometers below Earth’s surface. Radiolytic products may also be significant for sustaining life in subseafloor sediment and subsurface environments...

2021, Conservation Biology (35) 1627-1638
Many questions relevant to conservation decision making are characterized by extreme uncertainty due to lack of empirical data and complexity of the underlying ecological processes, leading to a rapid increase in the use of structured protocols to elicit expert knowledge. Published ecological applications often employ a modified Delphi method, where...

David R. Smith, Joshua Newhard, Conor P. McGowan, C. Alyssa Butler
2020, Frontiers in Marine Science (7)
In the U.S., 525,000 horseshoe crabs (Limulus polyphemus) per year have been captured during 2013–2017, brought to biomedical facilities, and bled to produce Limulus amebocyte lysate (LAL), then mostly released to the area of capture. The Atlantic States Marine Fisheries Commission estimates short-term bleeding-induced mortality to be 15% (4% to...
