Data includes fish abundance and habitat data collected at ten sites in the Sandusky River, OH. Fish were collected using two 3.67 m long hoop nets with an initial hoop diameter of 0.91 m. Nets were set perpendicular to the current, opening toward the shoreline. Nets were set for approximately 24 hours and catch rates for each set were defined as the number of fish caught in the two hoop nets per 24-hour sampling period. Fish were identified to species, measured for total length (mm), and released. Water quality was taken daily at each site at approximately the same time of day with a YSI Exo2 multiparameter sonde. Physical habitat data was recorded at the start of each trial. Vegetation coverage was characterized...

From 2010-2018 we investigated the occurrence of avian influenza antibody in wild birds in Iceland. A total of 2453 serum samples were collected from wild birds. We tested all samples by enzyme-linked immunosorbent assay (ELISA) for evidence of previous exposure to avian influenza virus with 1302 testing positive.

Monitoring wild fish health and associated exposure effects in regions where agriculture and development have impacted rivers and streams has become a valuable research tool. Smallmouth bass (Micropterus dolomieu) are a sensitive, indicator species that exhibit symptoms of immunosupression and endocrine disruption in response to water quality changes and contaminant exposure. In the Susquehanna River drainage, smallmouth bass have been used in biomonitoring assessments to help understand changes in the population due to poor young-of-the-year recruitment and health effects. To help determine effects of agriculture and development on smallmouth bass health, two sites (a developed/agriculture site and a forested site)...

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Dedicated Dredging on the Barataria Basin Landbridge (BA-36) project for 2018 and 2021. This data is used as a basemap land-water classifications. It also serves as a visual tool for project managers to help them identify any obvious problems...
In 2016, for the first time, an abundance of age-0 silver carp (Hypophthalmichthys molitrix) were captured at several sites upstream of Lock and Dam 19 on the Upper Mississippi River near Keokuk, Iowa. These data were collected in an attempt to determine the early life environments and frequency and timing of the reproductive events that led to a large year class of age-0 silver carp. This information is important for informing decisions about control measures. We sampled these fish to determine age (days) and early life environments using their otoliths. Sampled age-0 silver carp were collected from navigation Pools 18 and 19 from July–October 2016 using a variety of sampling gears. We aged these fish by counting...

These data are the results of a spatially interpolated integrated population model (SIIPM) fit to count and demographic data collected from populations of Greater Sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) located in Nevada, U.S.A. during 2013-2021. We used a novel framework, using integrated population models (IPMs), to express demographic relatedness among sampled and unsampled populations using geographic principles of spatial autocorrelation (Shepard, 1968; Tobler, 1970). Specifically, the framework pairs relatively inexpensive population count data with spatially interpolated demographic estimates. When conducted within a Bayesian framework, spatially interpolated demographic parameters...
The Kentucky Department of Fish and Wildlife Resources and Tennessee Wildlife Resource Agency conducted observations onboard commercial fishing vessels. During these observations total lengths were collected from a subset of that capture which we have used to develop a length-based stock assessment of invasive carp. The first dataset represent harvest from the invasive carp harvest program in Kentucky and Tennessee from 2009-2021 only in Lake Barkley and Kentucky Lake where the majority of harvest occurs. The second data are length data from a subset of those fish harvested in 2018-2021. The last dataset are the results from a survey delivered to fishers participating in the invasive carp harvest program in Kentucky...

Twenty-three long-term mangrove vegetation plots were established between 1992-1997 within the southwest coastal region of Everglades National Park (Florida, USA) to quantify tree damage and recovery following hurricanes and to understand the effects of global climate change. Many of the mangrove vegetation plots were associated with hydrology, soil porewater, and soil surface elevation monitoring stations. Within each plot, trees were tagged, mapped, and identified to species. The diameter at breast height (DBH) and status of each tree were measured at one to two year intervals through 2011. This dataset includes 51,730 tree measurements.

This data set represents an ecological and laboratory-based experiment to understand influenza virus viability in surface water. Data tables included in this release consist of 1) daily mean water temperature, 2) viability of viruses maintained in water, 3) influenza detection in duck samples, 4) viral titers of experimentally inoculated water samples, and 5) water chemistry.
