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 data, six samples were collected within 2-3 riffle areas within each site location with Portable Invertebrate Box Samplers (0.1-m2 sample area, 350 micron mesh collecting nets). Where possible, organisms were identified to the genus taxonomic level using a stereoscope except for organisms of the family Chironomidae and class Oliogochaeta,...

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 provided describing pool morphology, canopy cover, and fish cover (boulders, large woody debris, and undercut banks).

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 data are also reported for fish sampling sites.

A combination of long-term daily temperature records and depth to bedrock measurements were used to parameterize one-dimensional models of shallow aquifer vertical heat transport in Shenandoah National Park, VA, USA. Spatially discontinuous roving water surface and bank temperatures surveys were performed with a handheld thermal infrared camera in September and December 2015 along the main channel of a headwater stream supporting coldwater-dependent brook trout (Salvelinus fontinalis). We also installed vertical arrays of thermal data loggers to estimate bulk thermal diffusivity of the saturated alluvium at two stations in the upper trout section. The methods are fully documented in the associated journal article,...

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 2003. The database contains three separate table files (i.e., entities) in csv format: 1) Salamander egg mass/larval abundance counts; 2) site habitat data; and 3) site location data. The salamander data file includes egg mass counts for Spotted and Jefferson salamanders and presence/absence data for Marbled salamander larvae for Marbled salamanders...
