Base-flow sampling to enhance understanding of the groundwater flow component of nitrogen loading in small watersheds draining into Long Island Sound
Kaitlin L. Laabs, Janet R. Barclay, John R. Mullaney
2025, Data Report 1206
Excessive nitrogen discharge is a major concern for the Long Island Sound. Programs have been implemented to reduce point sources of nitrogen to the sound, but little is known about the nonpoint sources. This study aims to better understand the current groundwater contributions of nitrogen from nonpoint sources in the...

Jeremy Giovando, Wyatt Reis, Wei Zhang, Nancy A. Barth
2025, Hydrological Processes (39)
In June 2022, a historic flood event occurred in the headwaters of the Yellowstone River Basin. The flood resulted in millions of dollars in damages and substantial interruptions to Yellowstone National Park. The 2022 flood event was substantially higher in magnitude than other high-peak flow events over the last 30 years....
Evidence of red fox (Vulpes vulpes) depredating a Saltmarsh Sparrow (Ammospiza caudacuta) nest
Bridget Re, Sarah M. Karpanty, Elizabeth Ann Hunter
2025, The Wilson Journal of Ornithology (137) 647-654
Saltmarsh Sparrows (Ammospiza caudacuta), a tidal-marsh specialist, face severe population declines due to habitat loss, sea-level rise, and predation. While previous research suggests that predation pressure increases at the southern extent of the species’ breeding range, data on local predator communities remain limited. To address this, we...

P. J. Rudershausen, Matthew J. O'Donnell
2025, Journal of Fish of Biology (107) 188-200
The mummichog Fundulus heteroclitus is a trophically important fish inhabiting Atlantic coastal salt marshes, with few in situ estimates of overwinter survival throughout the species range. We estimated overwinter apparent survival rates of F. heteroclitus at the approximate mid-latitudinal species range [coastal North Carolina (USA)] in four tidal creeks that experience variable winter water...

2025, Emerging Infectious Diseases (31) 804-808
Serum samples from wild mammals inhabiting Alaska, USA, showed that 4 species, including Ursus arctos bears and Vulpes vulpes foxes, were exposed to influenza A(H5N1) viruses. Results indicated some mammals in Alaska survived H5N1 virus infection. Surveillance efforts may be improved by incorporating information on susceptibility and detectable immune responses among wild mammals....

2025, Journal of Animal Ecology (94) 932-942
1. Population ecology and biogeography applications often necessitate the transfer of models across spatial and/or temporal dimensions to make predictions outside the bounds of the data used for model fitting. However, ecological data are often spatiotemporally unbalanced such that the spatial or the temporal dimension tends to contain more data...

Catherine A. Nikiel, Marta P. Lyons
2025, Open-File Report 2021-1104-F
Laterallus jamaicensis jamaicensis (eastern black rails; Gmelin, 1789) are facing increasing risk from flooding in coastal breeding habitats because of rising sea levels combined with standard high tide flooding. In this report, we examine regional differences in relative rates of sea level rise, days in the breeding season above historical...

1. Patterns of migratory connectivity are increasingly used to understand and manage threats throughout the annual cycle of migratory species. Strong migratory connectivity refers to when individuals from different populations remain spatially separated across the annual cycle, which may expose populations to unique sets of threats and conditions that cause...
Assessing decadal-scale coastal change likelihood to define the accuracy and application of scientific information
Elizabeth A. Pendleton, Erika E. Lentz, Rachel E. Henderson, Julia L. Heslin, Marie Kathleen Bartlett, Travis K. Sterne
2025, Journal of Coastal Research (41) 770-785
Defining the accuracy and uncertainties of scientific data products is critical to the usability and trustworthiness of scientific information for environmental management and conservation purposes, such as coastal resource prioritization, design, adaptation, and mitigation. The U.S. Geological Survey has a new decadal-scale coastal change assessment product that synthesizes nearly two...
Dynamic rating method for computing discharge and stage from time-series data
Marian M. Domanski, Robert R. Holmes, Jr., Elizabeth Heal, Travis M. Knight
2025, Scientific Investigations Report 2024-5129
Ratings are used for several reasons in water-resources investigations. The simplest rating relates discharge to the stage of a river (the stage-discharge relation). From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because flow becomes unsteady as a...

Amanda Nicole May, Irene Fisher, Amy E. Simonson, Banu Bayraktar
2025, Scientific Investigations Report 2025-5010
The area locally known as the “Central Pine Barrens” region, located in Suffolk County, New York, contains most of Long Island’s preserved and undeveloped land. This region overlays an aquifer system that provides potable groundwater for residents of Suffolk County. Between 2017 and 2023, the U.S. Geological Survey, in cooperation...
Effects of northern bobwhite habitat management on avian species of conservation concern
Johanna M. H. Ford, Anna Maureen Tucker, Adam K. Janke, Tyler M. Harms, Riggs O. Wilson
2025, Ecological Indicators (172)
The umbrella species concept is often used as a tool to guide management decisions and focus efforts towards one focal species whose habitat needs overlap that of other species. We assessed this concept in the context of an agriculturally dominant landscape using one of the most well-studied avian species in...
World minerals outlook—Cobalt, gallium, helium, lithium, magnesium, palladium, platinum, and titanium through 2029

2025, Scientific Investigations Report 2025-5021
Given the rapid expansion in the demand for mineral commodities that underpin worldwide economic growth and technological advancement, information regarding expected country-level mine production and production capacity is becoming increasingly important to industry stakeholders, end users, and policymakers. Production capacity can limit future supply, depending on how rapidly that capacity...
Evidence for size‐based predation risk during Atlantic salmon (Salmo salar) smolt migration.
Matthew A. Mensinger, Alessio Mortelliti, Joseph D. Zydlewski
2025, Journal of Fish Biology
Hatchery supplementation is frequently employed during the conservation and recovery of imperilled salmon populations. At the smolt stage, hatchery rearing practices often produce individuals that are larger than wild conspecifics. Under this ‘bigger is better’ strategy, it is assumed that larger fish are less susceptible to predation during migration. We...
