Ambystomatid salamander population and breeding pond habitat data for the Delaware Water Gap National Recreation Area (2001 - 2003)

This database contains breeding pond use data (i.e., egg mass and larval abundance counts) of three ambystomatid salamander species (Spotted salamander, Jefferson salamander, and marbled salamander) collected from 200 individual aquatic habitats (ponds, wetlands, and impoundments) in the Delaware Water Gap National Recreation. Data were collected between the years 2001 and 2

Video data for trout abundance estimation

Rapid advances in video technology are enabling new strategies for species abundance estimation. Here we provide estimates of fish abundance derived from video data collected in a series of stream pools in Shenandoah National Park, Virginia (n=41). Two 360-degree cameras were simultaneously used at each pool site where 15-minutes of underwater footage was collected. Environmental data are

Environmental data collected at piezometer field plot locations used to study hydrologic impacts on vegetation due to historic rail road embankment at Canaan Valley NWR

This data represents environmental attributes collected at or around field sample locations (groundwater piezometers or water wells) that were used in a study of impacts from a historic railroad embankment on wetland vegetation. GPS surveys were used to map piezometer locations, elevations, and the elevation of the ground surface in proximity to the piezometer. Water surface elevations

Benthic macroinvertebrates abundance data for the study of urbanization effects in the Delaware Water Gap National Recreation Area, (2006)

This database contains aquatic benthic macroinvertebrate abundance data derived from samples collected from 33 75-meter stream site locations within the Delaware Water Gap National Recreation area in September of 2006. The database contains two separate table files (i.e., entities) in csv format: 1) Macroinvertebrate site abundance data and 2) site location data. For macroinvertebrate

Flume facility data collection at the S.O. Conte Anadromous Fish Research Laboratory in Turners Falls, MA for the 2016-2017 Fishway Entrance Gate Project

This data was collected over the course of two years, from 2016 to 2017, within the flume facility laboratory. The research project that was conducted evaluated different fishway entrance designs and their effect on the passage of adult American shad (Alosa sapidissima). The data consists of 15 columns and 1925 rows. Each row entry pertains to the performance of a single fish during on

Laboratory study investigating the effects of seasonal temperature and photoperiod manipulation on Eastern elliptio reproduction

A laboratory study was conducted at the Northern Appalachian Research Laboratory (Wellsboro, PA) on the ability to manipulate photoperiod and water temperatures to determine its effects on Eastern elliptio freshwater mussel glochidia production. Brooding mussels were collected from Pine Creek, Tioga County, PA in late December and were housed in the laboratory in groups subjected to on

Health Assessment of Brown Bullhead (Ameiurus nebulosus) at Selected Great Lakes Areas of Concern, 2011-2013

A total of 878 adult brown bullhead were collected at 11 sites within the Lake Erie and Lake Ontario drainages from 2011 to 2013. The sites included seven Areas of Concern (AOC; 670 individuals), one delisted AOC (50 individuals) and three nonAOC sites (158 individuals) used as reference sites. These fish were used to assess the “fish tumor or other deformities” beneficial...

Shale gas data used in development of the Disturbance Intensity Index for the Pennsylvania portion of the Upper Susquehanna River basin in Maloney et al. 2018.

Data on 17 metrics of shale gas development in the Pennsylvania portion of the Upper Susquehanna River basin that was collated from a variety of sources and summarized at the upstream catchment scale. Data were also standardized by upstream area and transformed into rank scores based on metric distribution and then summarized into a Disturbance Intensity Index (DII). See Maloney et al. 2018...

Molecular detection of avian influenza virus from sediment samples in waterfowl habitats on the Delmarva Peninsula, USA

Data were collected as part of an investigation developed by Leetown Science Center to investigate the comparative detection of avian influenza viruses from waterfowl and potential environmental reservoirs such as aquatic sediment from waterfowl habitat. This dataset identifies positive or negative test results for qRT-PCR (quantitative reverse transcriptase polymerase chain reaction) for avi...
