Integrating data types to estimate spatial patterns of avian migration across the Western Hemisphere Integrating data types to estimate spatial patterns of avian migration across the Western Hemisphere
For many avian species, spatial migration patterns remain largely undescribed, especially across hemispheric extents. Recent advancements in tracking technologies and high-resolution species distribution models (i.e., eBird Status and Trends products) provide new insights into migratory bird movements and offer a promising opportunity for integrating independent data sources to describe...

Whooping and sandhill cranes visit upland ponds proportional to migration phenology on the Texas coast Whooping and sandhill cranes visit upland ponds proportional to migration phenology on the Texas coast
Two crane species, whooping cranes (Grus americana) and sandhill cranes (Antigone canadensis), overwinter along the Texas Gulf Coast. Periodic, extreme drought conditions have prompted concerns that potential freshwater limitations could hinder conservation of cranes, especially endangered whooping cranes. In response, land managers constructed and maintained freshwater ponds in upland...

Yuma Ridgway’s rail selenium exposure and occupancy within managed and unmanaged emergent marshes at the Salton Sea Yuma Ridgway’s rail selenium exposure and occupancy within managed and unmanaged emergent marshes at the Salton Sea
Yuma Ridgway’s rail (Rallus obsoletus yumanensis, hereafter, rail) is an endangered species for which patches of emergent marsh within the Salton Sea watershed comprise a substantial part of habitat for the species’ disjointed range in the southwestern United States. These areas of emergent marsh include (1) marshes managed by federal (particularly the U.S. Fish and Wildlife Service’s...

Oklahoma and Landsat Oklahoma and Landsat
Oklahoma benefits from a varied landscape abundant in resources. Mountains, grasslands, reservoirs, rivers, fields, and forests offer employment and enjoyment in a State that epitomizes the transition from north to south and east to west. Wheat grows in northern Oklahoma; cotton grows in the south. Wetter deciduous forest lands in the southeast contrast with drier mesas in the northwest...

Changes in waterfowl migration phenologies in central North America: Implications for future waterfowl conservation Changes in waterfowl migration phenologies in central North America: Implications for future waterfowl conservation
Globally, migration phenologies of numerous avian species have shifted over the past half-century. Despite North American waterfowl being well researched, published data on shifts in waterfowl migration phenologies remain scarce. Understanding shifts in waterfowl migration phenologies along with potential drivers is critical for guiding future conservation efforts. Therefore, we utilized

Geospatial analysis delineates lode gold prospectivity in Alaska Geospatial analysis delineates lode gold prospectivity in Alaska
Comprehensive, data-driven geographic information system analyses utilize publicly available lithologic, geochemical, geophysical, and mineral occurrence datasets to delineate gold resource potential in Alaska. These prospectivity analyses successfully identify areas containing known lode gold occurrences, expand areas of high prospectivity around known occurrences, improve the precision...

Accelerated sea-level rise is suppressing CO2 stimulation of tidal marsh productivity: A 33-year study Accelerated sea-level rise is suppressing CO2 stimulation of tidal marsh productivity: A 33-year study
Accelerating relative sea-level rise (RSLR) is threatening coastal wetlands. However, rising CO2 concentrations may also stimulate carbon sequestration and vertical accretion, counterbalancing RSLR. A coastal wetland dominated by a C3 plant species was exposed to ambient and elevated levels of CO2 in situ from 1987 to 2019 during which time ambient CO2 concentration increased 18% and sea...

Variation of cisco egg size among Laurentian Great Lakes populations Variation of cisco egg size among Laurentian Great Lakes populations
Many fish species display inter-population and inter-individual egg size variation. Intra-specific differences in egg size seemingly reflect both energetic experiences of individual spawning fish and long-term population responses to differing ecosystems. Optimal egg size theory implies that selection influences a population’s mean egg size in response to its early-life environment...

Continuous stream discharge, salinity, and associated data collected in the lower St. Johns River and its tributaries, Florida, 2020 Continuous stream discharge, salinity, and associated data collected in the lower St. Johns River and its tributaries, Florida, 2020
The U.S. Army Corps of Engineers, Jacksonville District, is deepening the St. Johns River channel in Jacksonville, Florida, from 40 to 47 feet along 13 miles of the river channel beginning at the mouth of the river at the Atlantic Ocean, in order to accommodate larger, fully loaded cargo vessels. The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, monitored...

Water quality in the Missouri River alluvial aquifer near the Independence, Missouri, well field, 1997–2018 Water quality in the Missouri River alluvial aquifer near the Independence, Missouri, well field, 1997–2018
Groundwater-quality data collected from 1997 through 2018 from 68 monitoring locations open to the Missouri River alluvial aquifer (hereafter referred to as the “alluvial aquifer”) near the Independence, Missouri, well field were analyzed by the U.S. Geological Survey, in cooperation with the City of Independence, Missouri. This analysis was done to assess the quality of the water in the...

Aqueous geochemistry of waters and hydrogeology of alluvial deposits, Pinnacles National Park, California Aqueous geochemistry of waters and hydrogeology of alluvial deposits, Pinnacles National Park, California
A cooperative study between the National Park Service (NPS) and the U.S. Geological Survey (USGS) characterized groundwater quality and hydrogeology in parts of Pinnacles National Park. The water-quality investigation assessed the geochemistry of springs, wells, surface water, and precipitation and analyzed geochemistry of rock formations that affect the water chemistry through water...
