Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016 Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016
This dataset contains data from time-constrained visual encounter surveys conducted in the Atchafalaya River Basin in South Central Louisiana from February 2008 through July 2016. In addition, it contains vocalization data collected concurrently with the visual encounter surveys and data on presence of tadpoles and larvae. All participants in surveys are included in the dataset...
Code to assemble and generate output for an integrated population model of the endangered Cape Sable Seaside Sparrow Code to assemble and generate output for an integrated population model of the endangered Cape Sable Seaside Sparrow
This data release contains the R code to run an integrated population model (IPM) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis), a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA, and provides the parameter estimates from the model. The IPM synthesizes thirty years (1992-2021) of range-wide surveys, mark-resight, and...
Bibliography of U.S. Geological Survey Contributions to Carbon and Greenhouse Gas Science Bibliography of U.S. Geological Survey Contributions to Carbon and Greenhouse Gas Science
This data release contains a bibliography of U.S. Geological Survey publications on carbon and greenhouse gas research. Publications between 2014 and 2024 were identified using search terms such as: carbon, greenhouse gas, methane, nitrous oxide, emission, sequestration, and primary productivity. Publications were primarily sourced from the USGS Publications Warehouse (https://pubs.usgs...
Building a bioenergetics model for landbird conservation in the northern Gulf of America (Gulf of Mexico) region: energy supply, bird energy demand, and surplus/deficit maps Building a bioenergetics model for landbird conservation in the northern Gulf of America (Gulf of Mexico) region: energy supply, bird energy demand, and surplus/deficit maps
The majority of landbirds breeding in eastern North America migrate through the Gulf of America (Gulf of Mexico; hereafter Gulf) region during spring and fall. Rarely do migratory landbirds make nonstop flights between breeding and non-breeding areas, rather they stopover in habitats (a.k.a. stopover sites) en route to rest and refuel. Forested habitats in the northern Gulf region...
2023 TX_LowerRioGrande Orthoimagery 2023 TX_LowerRioGrande Orthoimagery
This TX_LowerRioGrande_D22 project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at an aggregate nominal pulse spacing (ANPS) of 0.18 meters (30 ppsm) and 0.35 meters (8ppsm). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification 2022 Rev A. The data was developed based...
Isotope data of vesicomyid clams collected in the Pacific Ocean off the Oregon coastline in 2019 Isotope data of vesicomyid clams collected in the Pacific Ocean off the Oregon coastline in 2019
Isotope data for vesicomyid clams collected in the Pacific Ocean off the Oregon coastline in 2019.
Evaluating changes in Piping Plover home ranges following coastal restoration at Whiskey Island and Caminada Headland, Louisiana from 2013 to 2019 Evaluating changes in Piping Plover home ranges following coastal restoration at Whiskey Island and Caminada Headland, Louisiana from 2013 to 2019
Over time, barrier islands may become eroded and experience land loss, which require management actions to restore island integrity. The process of restoring barrier islands can create new habitats but also alter existing habitats, which can impact the organisms depending on coastal habitats, such as the Endangered Species Act-listed Piping Plover (Charadrius melodus). Therefore, we...
Greater Everglades Burmese Python Stable Isotope Data and Standard Ellipse Area Literature Review Greater Everglades Burmese Python Stable Isotope Data and Standard Ellipse Area Literature Review
Burmese pythons are an invasive species in the Greater Everglades Ecosystem. Burmese pythons captured in the ecosystem are euthanized, and in an effort to learn about this invasive species, all euthanized pythons are necropsied, during which time samples are collected. We analyzed the stable isotope ratios of carbon and nitrogen in muscle samples from 423 Burmese pythons euthanized and...
Timing of coral (Swiftia exserta) spawning in U.S.G.S. Wetland and Aquatic Research Center, Gainesville, FL Timing of coral (Swiftia exserta) spawning in U.S.G.S. Wetland and Aquatic Research Center, Gainesville, FL
The 2010 Deepwater Horizon oil spill injured mesophotic and deep-sea environments over a vast area. In order to restore the mesophotic and deep-sea coral species impacted by the spill, information on fundamental ecosystem processes such as reproduction is needed. During expeditions in 2021 and 2022, fragments of the mesophotic octocoral Swiftia exserta were collected from the northern...
RNA yield and sequencing data from Exosomal miRNA isolation in white-tailed deer (Odocoileus virginianus) for diagnostic biomarker discovery RNA yield and sequencing data from Exosomal miRNA isolation in white-tailed deer (Odocoileus virginianus) for diagnostic biomarker discovery
This study presents the isolation of exosomes and RNA from 20 samples of white-tailed deer serum using a commercially available kit, incorporating optimizations for RNA yield through two elutions and replicate pooling. The RNA yield from each method is reported, with six samples processed using three techniques. Seven samples underwent RNA sequencing, where total RNA was prepared for...
Water Level, Salinity, and Elevation Data at Turtle Bayou Mitigation Area of Bayou Sauvage National Wildlife Refuge, 2024 Water Level, Salinity, and Elevation Data at Turtle Bayou Mitigation Area of Bayou Sauvage National Wildlife Refuge, 2024
Bayou Sauvage National Wildlife Refuge (BSNWR) is an urban refuge in southeastern Louisiana that has been altered extensively due to human impacts. As a result, the hydrology of the impounded (interior) marshes within the BSNWR has been disrupted due to obstructions such as spoil banks, levees, and water control structures that affect the gradient and fluctuation of water surface...
Wetland transformations for three relative sea-level rise scenarios along the middle and upper Texas Coast, wetland current condition map and wetland transformation maps by decade, sea-level rise scenario, and coastal wetland drowning threshold (ver. 2.0, Wetland transformations for three relative sea-level rise scenarios along the middle and upper Texas Coast, wetland current condition map and wetland transformation maps by decade, sea-level rise scenario, and coastal wetland drowning threshold (ver. 2.0,
As sea levels rise, wetlands exposed to oceanic water can adapt to changing conditions through vertical development (i.e., soil surface elevation gains via biophysical feedbacks) and horizontal migration into upslope areas. Elevation-based models of wetland transformation from sea-level rise are often hampered from a variety of sources of uncertainty, including contemporary elevation and...
