These two datasets represent a normalized least-cost corridor mosaic (see WHCWG 2010 and McRae and Kavanagh 2011) calculated using (1) temperature gradients and a landscape integrity resistance raster, or (2) temperature gradients only, following the climate gradient linkage-modeling methods outlined in Nuñez (2011), using an adapted version of the Linkage Mapper software (McRae and Kavanagh 2011). This GIS dataset is one of several climate connectivity analyses produced by Tristan Nuñez for a Master's thesis (Nuñez 2011). The dataset was produced in part to assist the Climate Change Subgroup of the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The core areas in the map lie in Washington State...

Data described herein was collected by USGS personnel and the project funded by USGS and the National Park Service (Catoctin Mountain Park) through a FY14 NRPP project involving both agencies and developed to detect the presence and prevalence of ranavirus and chytrid pathogens among amphibians of Catoctin Mountain Park (CATO). Supplemental molecular analyses were performed on behalf of LSC by the molecular biology laboratory at Hagerstown Community College whereby students performed the molecular diagnostic testing and provided the raw data to LSC for analysis. There is no data sharing agreement specifying ownership, but the data was presented to the NPS CATO staff to help guide their management decision-making...

See description for each data layer. NOTE: Databasin was unable to display the appropriate color ramping for the corridor layers; higher resolution layers and images for the climate-gradient corridor analysis can be found at www.waconnected.org.

Data described herein was collected by USGS personnel and the project funded by USGS. Northern snakehead specimens were collected from the Potomac River and its tributaries by regional natural resource management agencies in the course of their field investigations working with this priority invasive aquatic species. Specimens were provided to USGS for the purpose of conducting health related assessments of northern snakehead in the region, with approximately 90 specimens evaluated grossly and histologically for the presence of lesions and abnormalities. Data presented here was collected seasonally (spring through fall) in 2006 and from 2015 to 2017. Data for each specimen includes date and location of collection,...
