Fish species abundance data for selected streams of the Potomac River basin

This Data Release contains data on fish species abundance for selected streams of the Potomac River basin in eastern North America. This dataset supports analysis of karst streams in the Chesapeake Bay headwaters region and was funded by USGS Chesapeake Bay studies.

Stream temperature observations during summer 2021 for sites in the Antietam Creek watershed, Maryland

This Data Release contains stream temperature observations for 28 sites in the Antietam Creek Watershed (Maryland) during summer 2021. Data were collected using Onset ProV2 temperature gages within perforated PVC cases attached to stream substrates with rebar. Temperature gages were deployed and retrieved by volunteers with the Antietam-Conococheague Watershed Alliance. Temperature records are pro

Data regarding the efficacy of management practices for controlling gull use of Common Tern nesting colonies

These data, which support a paired USGS publication, describe the efficacy of several management practices for reducing the presence of herring gulls in the nesting colonies of Common Terns. This data was collected on Poplar Island, located in the Chesapeake Bay portion of Maryland.

Water Chemistry and Smallmouth Bass Biological Data From the Potomac River, Dargan, Maryland, 2013-2019

Decades of poor reproductive success and young-of-the-year recruitment, in addition to adult mortality, has led to a decline in the smallmouth bass (SMB) population in subwatersheds of the Potomac River. Previous studies have identified numerous biologic and environmental stressors associated with negative effects on SMB health. To better understand the impact of these stressors, the current study

North American Bird Banding Program Dataset 1960-2022 retrieved 2022-07-14

The North American Bird Banding Program is directed in the United States by the U.S. Geological Survey (USGS) Bird Banding Laboratory (BBL), Eastern Ecological Science Center at the Patuxent Research Refuge (EESC) and in Canada by the Bird Banding Office (BBO), Environment and Climate Change Canada (ECCC). The respective banding offices have similar functions and policies and use the same bands, r

Data describing the effects of elastic leg-loop harnesses on adult and juvenile Common Terns

These data describe the affects of elastic leg-loop harnesses on the reproductive success and behavior of adult Common Terns and the growth and behavior of juvenile Common Terns. These data support a USGS authored manuscript.

Data describing infection status and movement ecology of North American waterfowl

These data, which support a USGS authored manuscript, describe how active and previous previous infection with avian influenza impacts the movement ecology of several wild waterfowl species that overwinter in California. Results varied by species and demonstrate that the relationships between avian influenza infection and wild bird movements are context- and species-dependent.

Surface water estimates for a complex study site derived from traditional and emerging methods

These data describe the area of different habitat covered in water as determined via three approaches: manual surveys, digitized aerial imagery, and categorization of the newly available dynamic surface water extent dataset derived from satellite imagery. These data support a scientific publication.

West Brook Trout Data, Whatley, Massachusetts.

The Ecology Section at the USGS Conte Laboratory has studied fish in the West Brook since 1997. The goal is to understand the strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish population dynamics and ultimately individual fitness (natural selection and evolution) in the study area.

Spatial models indicating avian influenza transmission risk at the interface of domestic poultry and wild birds in China

Emergence of avian influenza viruses with high lethality to humans, such as the currently circulating highly pathogenic A(H5N1) and A(H7N9) cause serious concern for the global economic and public health sectors. To improve our understanding of the spatial and temporal trends in transmission risk we developed a model that predicts hotspots of novel virus emergence between domestic and wild birds a

Data measuring avian influenza infection, mercury concentration, and body condition in wild waterfowl

These data represent mercury contamination, influenza infection, and body condition in 11 species of dabbling and diving ducks in the Pacific Flyway. These data support a USGS lead scientific publication.

Weekly relative effective waterfowl populations across the United States based upon predicted abundance and viral prevalence by species - Initial phase models

This data layer depicts the weekly relative effective waterfowl populations across the United States based upon predicted abundance and viral prevalence by species. These data have been produced to allow for visualization of how different factors impact transmission risk and may be advanced in future iterations to include additional species.
