An automatable method for developing preliminary stream crossing designs using lidar and hydraulic modeling in Massachusetts An automatable method for developing preliminary stream crossing designs using lidar and hydraulic modeling in Massachusetts
Upgrading aging and undersized stream crossings (places where culverts and bridges intersect a stream) with replacements designed for aquatic organism passage can improve infrastructure resiliency, geomorphic stability, and maintenance costs. The goal of this work is to develop preliminary culvert designs that convey hydraulic design floods and meet the Massachusetts Stream Crossings...

The impacts of cover crop performance on satellite-based detectability of cover crops in the Maryland The impacts of cover crop performance on satellite-based detectability of cover crops in the Maryland
Cover crop adoption in the U.S. has increased over the past decades, increasing the need to quantify their performance and environmental benefits. While remote sensing (RS)-based approaches for detecting cover crop presence have been developed, there has been limited research on how cover crops with varied biomass and management practices influence detectability. Using unique field-level...

Plant diversity shifts with drying and wetting cycles following removal of poplar plantations in Dongting Lake, China Plant diversity shifts with drying and wetting cycles following removal of poplar plantations in Dongting Lake, China
Dongting Lake, the second largest lake in China, plays a crucial role in maintaining regional ecological security by providing key habitats for waterbirds. This study examined how hydrology and topography (ditches and mounds) together generate fine-scale wet–dry gradients that shape species establishment and successional trajectories. Over the past decade, vegetation restoration has been

Precipitation intensity increased across the South Pacific Convergence Zone in the Industrial Age Precipitation intensity increased across the South Pacific Convergence Zone in the Industrial Age
The position, strength, and variability of precipitation in the South Pacific Convergence Zone (SPCZ) remain challenging for coupled ocean-atmosphere climate models to represent, leaving future rainfall projections in this dynamically important region uncertain. Here, we present quantitative records of mean annual precipitation (MAP) spanning the past 1,000 years using sediment cores...

Methods for estimating selected low-flow frequency and mean annual flow statistics at gaged and ungaged locations on streams in Georgia, North Carolina, and South Carolina Methods for estimating selected low-flow frequency and mean annual flow statistics at gaged and ungaged locations on streams in Georgia, North Carolina, and South Carolina
The U.S. Geological Survey, in cooperation with the Georgia Department of Natural Resources (Environmental Protection Division), North Carolina Department of Environmental Quality (Division of Water Resources), North Carolina Department of Public Safety (Office of Recovery and Resiliency), and South Carolina Department of Environmental Services, updated low-flow frequency, mean annual...

High and dry: The persistence of diverse coastal marsh communities depends on available upland area and connection to surrounding waters High and dry: The persistence of diverse coastal marsh communities depends on available upland area and connection to surrounding waters
Sea-level-rise and alterations to natural hydrology have contributed to coastal land loss. To combat coastal land loss and maintain the ecosystem services provided by marshes, marsh creation has been broadly implemented. Marsh creation projects can be performed in conjunction with the construction of elevated terrestrial ridges that seek to mimic historic delta-formed distributary ridges...

Loss and transformation of coastal wetlands due to global change in the conterminous United States: Past, present, and future Loss and transformation of coastal wetlands due to global change in the conterminous United States: Past, present, and future
Coastal wetlands are being transformed by global change, impacting the ecological and societal benefits provided by these ecosystems. Synthesizing knowledge of historical and expected future transformations in coastal wetlands can help inform forward-looking planning and stewardship efforts. Here, we review anticipated future ecological transformations in coastal wetlands of the...

A practical framework for identifying genetic subpopulations and ESUs: Insights for IUCN assessments and broader management A practical framework for identifying genetic subpopulations and ESUs: Insights for IUCN assessments and broader management
Species conservation assessments evaluate extinction risk, and recovery potential, advancing species persistence through guiding resource prioritization and planning. Assessment frameworks, including the International Union for Conservation of Nature Red List and Green Status of Species, typically focus on species as a whole. Importantly, they do not routinely account for genetically...

Development of projected depth-duration-frequency curves for precipitation in Florida, 2020–59 and 2050–89 Development of projected depth-duration-frequency curves for precipitation in Florida, 2020–59 and 2050–89
The planning, permitting, and design of stormwater-management projects require estimates of the depths of extreme precipitation for current and future events with specified durations and return periods. In this project, precipitation data from six downscaled climate datasets were used to determine changes in precipitation depth-duration-frequency curves from the period 1966–2005 to the...

On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes
Grass carp (Ctenopharyngodon idella) is an invasive herbivore observed in small numbers in the Laurentian Great Lakes since the 1980 s with records from all lakes except Lake Superior. Identification of diploid, age-1 + grass carp from the Sandusky River, a Lake Erie tributary, in 2012, prompted targeted efforts to evaluate the status of grass carp reproduction in the Lake Erie Basin. In...

Cnidarian–algal partnerships structure bacterial communities during strobilation in Cassiopea xamachana Cnidarian–algal partnerships structure bacterial communities during strobilation in Cassiopea xamachana
Cnidarian–algal (Symbiodiniaceae) symbioses rely on complex interactions among the cnidarian host, algal symbionts, and associated bacterial communities. In the upside-down jellyfish Cassiopea xamachana, the polyp-to-medusa transition (strobilation) requires the establishment of symbiosis with Symbiodiniaceae algal partners, yet bacterial community dynamics during this developmental...

Strengthening ties between the U.S. Geological Survey and Interstate Fisheries Commissions Strengthening ties between the U.S. Geological Survey and Interstate Fisheries Commissions
Fish inhabiting marine coastal and Great Lakes waters of the United States forage, migrate, and reproduce without regard to human-made boundaries. In the mid-20th century, the 32 states along the U.S. coasts and Great Lakes recognized the growing need for coordinated, interjurisdictional fisheries management and formed four interstate or international fisheries commissions through...
