2024, Environmental Science and Policy (103775)
A structured decision making (SDM) approach can help evaluate tradeoffs between conservation and human-benefit objectives by fostering communication and knowledge transfer among stakeholders, decision makers, and the public. However, the process is iterative and completing the full process may take...
A new era of genetic diversity conservation through novel tools and accessible data
Margaret Hunter, Jessica M. da Silva, Alicia Mastretta-Yanes, Sean M. Hoban
2024, Frontiers in Ecology and the Environment (22)
As the foundation of biodiversity, genetic diversity is necessary for species to adapt to ecological changes, such as impacts from disease, invasive species, and climate change. Genetic diversity also supports ecosystem resilience and societal innovations. Unfortunately, declines in genetic diversity have been frequently observed in populations of wild and domestic...

Basin effects from 3D simulated ground motions in the Greater Los Angeles region for use in seismic-hazard analyses
Morgan P. Moschetti, Eric M. Thompson, Kyle Withers
2024, Earthquake Spectra (40) 1042-1065
We develop basin-depth-scaling models (i.e. “basin terms”) from the long-period (T≥2s) simulated ground motions of the Southern California Earthquake Center (SCEC) CyberShake project for use in seismic hazard analyses at sites within the sedimentary basins of southern California. Basin terms use the Next Generation Attenuation (NGA)-West-2 ground-motion models (GMMs)...

A video monitoring and computational system for estimating migratory juvenile fish abundance in river systems
Meghna N. Marjadi, Sidney Batchelder, Ryan Govostes, Allison H. Roy, John J. Sheppard, Meghan-Grace Slocombe, Joel K. Llopiz
2024, Limnology and Oceanography Methods (22) 295-310
Diadromous fishes migrate between marine and fresh waters for reproduction. For anadromous species, which spawn in freshwater, improved access to freshwater spawning and nursery habitats and ability of juveniles to emigrate to the ocean may support population recovery. Despite the potentially enormous influence of early life stage survival on adult...

Katelin M. Goebel, David E. Andersen, Pamela J. Rice, Nicole M. Davros
2024, Journal of Wildlife Management (88)
Soybean aphid (Aphis glycines) insecticides are used throughout the Upper Midwest and Great Plains regions of North America, including the farmland region of Minnesota, USA, to combat insect pests. These broad-spectrum, foliar spray insecticides have the potential to drift beyond target fields into nearby grassland cover where birds and other...

Land use and dog park associations with Escherichia coli in the Chattahoochee River National Recreation Area watershed
A.M. McKee, Ann M. Couch
2024, Science Report NPS/SR—2024/113
A recent study in the Chattahoochee River National Recreation Area (CHAT) indicated that dogs were a primary source of fecal contamination in the Chattahoochee River and that at least some of the contamination in the river was coming from locations outside of CHAT. The study herein sought to determine if...
Abundance of Long-billed Curlews on military lands in the Columbia Basin
Sharon A. Poessel, Elise Elliott-Smith, Sean M. Murphy, Susan M Haig, Adam E. Duerr, Todd E. Katzner
2024, Avian Conservation and Ecology (19)
Long-billed Curlews (Numenius americanus) are declining throughout North America, and the loss of grassland breeding habitat is one of the primary threats to the species. Intermountain West, in particular, has been identified as the most important region in North America for breeding curlews. Nevertheless, the density and abundance of Long-billed...
Revisiting geophysical interpretations of the Midcontinent Rift below Lake Superior— Insights from GLIMPCE seismic-reflection line C
V. J. S. Grauch, Samuel J. Heller, Laurel G. Woodruff, Esther K. Stewart
2024, Conference Paper, Institute on Lake Superior Geology: proceedings
The 1.1 Ga Midcontinent Rift System (MRS) has been investigated in the Lake Superior region for more than a century. The most influential geophysical data for modern paradigms has come from seismic-reflection profiles collected by the Great Lakes International Multidisciplinary Program on Crustal Evolution (GLIMPCE) in the late 1980s. We...

Why do seismic hazard models worldwide appear to overpredict historical intensity observations?
Leah Marschall Salditch, Molly M. Gallahue, Seth Stein, James S. Neely, Norman A. Abrahamson, Susan E. Hough
2024, Science Advances (10)
Probabilistic seismic hazard assessments (PSHAs) provide the scientific basis for building codes to reduce damage from earthquakes. Despite their substantial impact, little is known about how well PSHA predicts actual shaking. Recent PSHA for California, Japan, Italy, Nepal, and France appear to consistently overpredict historically observed earthquake shaking intensities. Numerical...
Evaluation of chronic effects of potassium chloride and nickel on survival, growth, and reproduction of a unionid mussel (Lampsilis siliquoidea)
Ning Wang, James L. Kunz, Danielle M. Cleveland, Rebecca A. Dorman, Jeffery A. Steevens, Sandy Raimondo, Tom Augspurger, M. Christopher Barnhart
2024, Environmental Toxicology and Chemistry (43) 1097-1111
The ASTM International standard test method for freshwater mussels (E2455‐13) recommends 4‐week toxicity testing with juveniles to evaluate chronic effects on survival and growth. However, concerns remain that the method may not adequately address the sensitivity of mussels to longer term exposures (>4 weeks), particularly in relation to potential reproductive...

Investigating past earthquakes with coral microatolls
Belle E. Philibosian
2024, Past Global Changes (PAGES) Magazine (32) 22-23
Intertidal corals (microatolls) preserve evidence of past uplift or subsidence with annual precision. Microatoll records are particularly useful along subduction zones, and can reveal past earthquake ruptures at a level of detail that is ordinarily limited to the instrumental era....

Michael P. Guilfoyle, Amanda Nicole Anderson, Samuel S. Jackson, Jacob F. Jung, Theodore J. Zenzal Jr., Burton C. Suedel, Jeffrey M. Corbino
2024, Report
Coastal bird populations in North America have experienced significant population declines over the past four decades, and many species have become dependent upon human-made islands and other sediment-based habitats created through dredged material deposition. We monitored the breeding phenology of coastal bird populations utilizing...
Evaluating effectiveness of restoration to address current stressors to riverine fish
Jane S. Rogosch, Hadley I. A. Boehm, Ralph W. Tingley III, Kiah D. Wright, Elisabeth B. Webb, Craig P. Paukert
2024, Freshwater Biology (69) 607-622
River restoration programmes with the goal of conserving and rehabilitating inland fishes have a multi-decadal history, but evaluation and synthesis of past restoration actions have been limited by a lack of monitoring and reporting. Given that calls for both monitoring and systematic reviews of restoration have increased, we were...

2024, Earthquake Spectra (40) 1066-1098
Several rupture directivity models (DMs) have been developed in recent years to describe the near-source spatial variations in ground motion amplitudes related to propagation of rupture along the fault. We recently organized an effort towards incorporating these directivity effects into the USGS National Seismic Hazard Model (NSHM), by first evaluating...
