Data

The effects of high- and low-flow conditions on biological communities in Alabama streams were investigated by utilizing data on benthic macroinvertebrates, fish communities, hydrology, land use, and water quality. Biological data from streams and rivers in the Mobile River basin and other Gulf Coast drainages was collected from 278 sites between 1999 and 2014. These sites' upstream...

Product Description: This dataset provides maps of peak biomass carbon stock (C) in gC/m2 and net primary productivity (NPP) in gC/m2/yr of coastal herbaceous wetlands at a resolution of 30 m across the conterminous United States (CONUS) for 2015. Aboveground, belowground, and total peak biomass C and NPP are provided for tidal herbaceous wetlands. Data is presented for 1. all herbaceous...

This metadata record contains two tables with reported and calculated amounts of biosolids applied to agricultural land within the Chesapeake Bay watershed in 2023 at different scales. Included in the dataset are (1) mass of land-applied biosolids calculated for NHDPlus Version 2.1 (NHDPlusV2) reach catchments in 2023 and (2) actual amount of biosolids applied to land by county in 2023...

These data pertain to bird point surveys collected from 30 April 2016 to 12 May 2016 and 23 May 2016 to 25 June 2016 at four bottomland hardwood restoration sites in northeastern Indiana. The data are a single monitoring occasion with the purpose of documenting bird communities across these sites. During the time of collection, sites contained areas of hardwood planting ranging in age...

Bird and habitat surveys were conducted in winter-flooded rice fields in the Sacramento Valley, California, USA during the fall and winters of 2021-2022 (Oct 2021 through February 2022) and 2022-2023 (December 2022 through February 2023). Rice field sampling consisted of (1) a bird survey that was followed by (2) an overall habitat assessment and (3) a more detailed habitat transect...

Tabular and raster data containing spatial capture recapture records for male and female black bears (Ursus americanus) in Glacier National Park and surrounding landscape collected from June - October 2004 and associated tabular data files required for analysis of data with spatial capture connectivity models and raster data describing the ouput from SCR models. Associated tables and...

These data represent the measurements of length and mouth gape from large juvenile and adult wild-caught and small juvenile hatchery origin black carp, and the results of laboratory size preference trials with bivalve prey, specifically Corbicula clams. Wild-caught black carp ranged from 429-1580 mm total length, a larger range than measured in previous studies. Corbicula feeding trial...

Black Carp collections (n=534) by commercial fishers, biologists, and recreational anglers from the Mississippi River basin recorded from 2018 to 2022 are reported here. Geographic coordinates, total length (TL), weight, girth, date of capture, sex, and gear were recorded. Total length was measured from the tip of the snout to the longest caudal fin ray with the caudal fin lobes pinched...

These data provide morphological measurements and primary feather length measurements of Black Oystercatcher (Haematopus bachmani) captured at several sites across Alaska and British Columbia between 2019 and 2022. The first table contains mass and morphological measurements of body and bill size. The second table provides lengths of individual primary feathers measured from folded wing

Body mass data (measured in grams) of dabbling and diving ducks harvested in three regions of California: Sacramento Valley, Suisun Marsh, and San Joaquin Valley during the 2014/2015, 2015/2016, 2016/2017, 2018/2019, and 2019/2020 hunting seasons. In addition to mass, the flattened length of right wing, species, sex, age, and date of harvest were also recorded. These data support the...

This data set, compiled by the USGS Lake Erie Biological Station, provides near-bottom measurements of temperature and dissolved oxygen for the Central Basin of Lake Erie. Data were recorded by self-contained environmental data loggers (PME, Inc., MiniDOT data loggers). The data loggers for 2023 were deployed to collect data during April 2023 through November 2023 to better understand...

This data release provides catch-per-unit-effort (CPUE) data by age-class for alewife (Alosa pseudoharengus) based on bottom trawl surveys from Lake Michigan (1973-2022) or Lake Huron (1976-2004). These data are associated with a study that sought to evaluate whether alewife populations across the Great Lakes are synchronous in their time series.
