Qualitative and quantitative surveys of native freshwater mussels in the upper and middle Delaware River (2000-2002)

Data is included for two types of field surveys conducted for freshwater mussels in the mainstem of the middle and upper Delaware River in the Mid-Atlantic region of the United States from 2000-2002. Timed search (qualitative) surveys were conducted during 2000-2001 from a point at the confluence of the East and West Branches of the Delaware River near Hancock, NY continuously downstream to a poin

Susquehanna River Basin freshwater mussel surveys: 2008-2015

Data are included for two types of field surveys conducted for freshwater mussels throughout the Susquehanna River Basin (and one site in the Potomac River Basin) in the Mid-Atlantic region of the United States from 2008-2010. Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river (at least 8 in each stream). The number of mussels of each species and associat

Site bathymetry, water temperature and rating curve 2004 and 2005 data for 3 sites in the Delaware River mainstem

Data were obtained in order to develop bathymetric maps, rating curve relationships between site stage and river flow conditions, and water temperature to better understand the habitat needs of the dwarf wedgemussel, Alasmidonta heterodon, to inform conservation of the species and management of the river. Data are included from three parts of the research in the Delaware River focusing on three si

Annual survival, site fidelity, and longevity in the eastern population of the Painted Bunting (Passerina ciris)

Data comprise 6632 observations of individually banded Painted Buntings, captured and observed from 1999-2016 at 40 study locations on the southeastern Atlantic Coast (NC, SC, GA and FL, US).

Preliminary evaluation of behavioral response of nesting waterbirds to small unmanned aircraft flight

This dataset is comprised of 3 .csv files related to the use of unmanned aerial systems over waterbird colonies. Specifically, data detail the disturbance observed in birds during flights, the time required for traditional ground surveys to be conducted, and the distance at which birds flush during traditional ground surveys.

Laboratory study on the effects of rearing temperature on American glass eels, Anguila rostrata (2011)

Data were collected on American glass eels (Anguilla rostrata) to determine optimal thermal conditions for laboratory rearing and aquaculture. American glass eels (Anguilla rostrata) were housed in buckets for 3 weeks at 14, 18, 22, or 26°C (n=5 buckets/treatment) to determine optimal juvenile rearing temperature in the laboratory. Initial weight (g) was recorded for each bucket. During the 3 week

North American Breeding Bird Survey Dataset 1966 - 2017, version 2017.0

The 1966-2017 North American Breeding Bird Survey dataset contains avian point count data for more than 700 North American bird taxa (primarily species, but also some races and unidentified species groupings). These data are collected annually during the breeding season, primarily June and May, along thousands of randomly established roadside survey routes in the United States and Canada. Routes

Water and air temperature data from Shenandoah Valley streams, Virginia (2017)

This Data Release provides hourly records of air and water temperature within 5 watersheds (Beaver Creek, Dry River, Mossy Creek, Passage Creek & Spout Run) in the Shenandoah Valley, VA in the summer of 2017. Data loggers were deployed and retrieved by Trout Unlimited personnel and volunteers.

Examination of contaminant exposure and reproduction of ospreys (Pandion haliaetus) nesting in Delaware Bay and River in 2015

Reproductive Data for All Nests Monitored; Data for Mayfield Analysis; Eggshell thickness, nestling morphological measurements, nestling plasma stable isotopes, and nestling red blood cell oxidative DNA damage; Egg organochlorine pesticide, total PCB, flame retardants, and PCB toxic equivalent concentrations; Fish capture by osprey; Fish pools and size for contaminant analysis; Fish organochlorine

Stream fish species abundance and associated physical habitat data in Catoctin Mountain Park (2015-2016)

This Data Release provides records of fish species abundance collected during summer 2015 using single pass backpack electrofishing within sections of Owens Creek, Big Hunting Creek, and Blue Blazes Creek (a tributary to Big Hunting Creek) in Maryland (USA). We also provide water and air temperature data collected during at 30 minute increments summers of 2015 and 2016. Stream physical habitat dat

Effects of local shoreline and subestuary watershed condition on waterbird use: influences of geography, scale, and season in the Chesapeake Bay

In many coastal regions throughout the world, there is increasing pressure to harden shorelines to protect human infrastructures against sea-level rise, storm surge and erosion. This study examines waterbird community integrity in relation to shoreline hardening and land use characteristics at three geographic scales: (1) the subestuary scale characterized by seven shoreline types: bulkhead, ripr

Estrogen Equivalents of Surface Water in the Upper Chesapeake Bay Watershed (2008 - 2011)

Intersex in small- and largemouth bass has been observed in the upper Chesapeake Bay Watershed since 2003. This observation is indicative of exposure to estrogenic endocrine disrupting chemicals. In order to complement biological data sets and better identify the spatial and temporal nature of this end-point, discrete grab water samples were collected throughout the upper Chesapeake Bay Watershed
