Testing megathrust rupture models using tsunami deposits Testing megathrust rupture models using tsunami deposits
The 26 January 1700 CE Cascadia subduction zone earthquake ruptured much of the plate boundary and generated a tsunami that deposited sand in coastal marshes from northern California to Vancouver Island. Although the depositional record of tsunami inundation is extensive in some of these marshes, few sites have been investigated in enough detail to map the inland extent of sand...

Development of a hydrogeologic visualization model for western Sarpy County, Nebraska Development of a hydrogeologic visualization model for western Sarpy County, Nebraska
Population in western Sarpy County, Nebraska, has steadily increased over the last several decades and has led to increased groundwater use for domestic purposes. To meet the increase in demand, the Papio-Missouri River Natural Resources District is seeking to use all available sources of groundwater in western Sarpy County. Additionally, elevated groundwater nitrate plus nitrite as...

Environmental DNA Environmental DNA
The widespread adoption of environmental DNA (eDNA) detection tools for biodiversity monitoring has led to the need for universal data standards to inform principled eDNA data applications. Improvements in understanding the meaning and possible uncertainty of eDNA data can minimize erroneous conclusions, increase confidence in eDNA data, and maximize conservation outcomes. -Environmental...

Milkweed and floral resource availability for monarch butterflies (Danaus plexippus) in the United States Milkweed and floral resource availability for monarch butterflies (Danaus plexippus) in the United States
The global decline of pollinators, particularly insects, underscores the importance of enhanced monitoring of their populations and habitats. However, monitoring some pollinator habitat is challenging due to widespread species distributions and shifts in habitat requirements through seasons and life stages. The monarch butterfly (Danaus plexippus), a migratory insect pollinator that...

READI-Net—Providing tools for the early detection and management of aquatic invasive species READI-Net—Providing tools for the early detection and management of aquatic invasive species
Overview Early detection of biological threats, such as invasive species, increases the likelihood that control efforts will be successful and cost-effective. Environmental deoxyribonucleic acid (eDNA) sampling is an established method for the efficient and sensitive early detection of new biological threats. The Rapid eDNA Assessment and Deployment Initiative & Network (READI-Net) is a...

Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey
Executive Summary Algal blooms in water, soils, dusts, and the environment have captured national attention because of concerns associated with exposure to algal toxins for humans and animals. Algal blooms naturally occur in all surface-water types and are important primary producers for aquatic ecosystems. However, excessive algae growth can be associated with many harmful effects...

Real-time invasive sea lamprey detection using machine learning classifier models on embedded systems Real-time invasive sea lamprey detection using machine learning classifier models on embedded systems
Invasive sea lamprey (Petromyzon marinus) has historically inflicted considerable economic and ecological damage in the Great Lakes and continues to be a major threat. Accurately monitoring sea lampreys are critical to enabling the deployment of more targeted and effective control measures to minimize the impact associated with this species. This paper presents the first stand-alone...

Capturing potential: Leveraging grass carp behavior Ctenopharyngodon idella for enhanced removal Capturing potential: Leveraging grass carp behavior Ctenopharyngodon idella for enhanced removal
Effective management of invasive species benefits from a comprehensive understanding of the species’ behavior and interactions with the invaded system. We investigated temporal dynamics of telemetry detections and the potential utility of a traitor approach for informing response efforts to the invasive grass carp (Ctenopharyngodon idella) population in the Sandusky River, a major...

Peak streamflow trends in Michigan and their relation to changes in climate, water years 1921–2020 Peak streamflow trends in Michigan and their relation to changes in climate, water years 1921–2020
This study characterizes hydroclimatic variability and change in peak streamflow and daily streamflow in Michigan from water years 1921 through 2020. Four analysis periods were examined: the 100-year period from water year 1921 through 2020, the 75-year period from water year 1946 through 2020, the 50-year period from water year 1971 through 2020, and the 30-year period from water year...

Multinational evaluation of genetic diversity indicators for the Kunming-Montreal Global Biodiversity Framework Multinational evaluation of genetic diversity indicators for the Kunming-Montreal Global Biodiversity Framework
Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed, two of which focus on processes contributing to genetic diversity conservation: maintaining genetically distinct populations and ensuring populations are...

Declining groundwater storage expected to amplify mountain streamflow reductions in a warmer world Declining groundwater storage expected to amplify mountain streamflow reductions in a warmer world
Groundwater interactions with mountain streams are often simplified in model projections, potentially leading to inaccurate estimates of streamflow response to climate change. Here, using a high-resolution, integrated hydrological model extending 400 m into the subsurface, we find groundwater an important and stable source of historical streamflow in a mountainous watershed of the...
