These data represent capture histories for humpback chub (Gila cypha) that spawn in the Little Colorado River (LCR) from 2009-2017. Capture histories pertain to size class (<150mm total length [TL], 150-199mm TL, 200-249mm TL, and >250mm TL) and spatial location (the juvenile chub monitoring [JCM] reach in the Colorado River [63.4-65.0 river miles downstream of Lees Ferry], lower LCR [0-13.56 km upstream of Colorado River confluence], and upper LCR [13.57-17.9 km upstream of Colorado River confluence]).
Point shapefile of Wind Turbine locations in Wyoming as of December 2010. Turbine location and attribute data extracted from the FAA Obstruction Evaluation Database (https://oeaaa.faa.gov/oeaaa/external/portal.jsp). The FAA requires evaluation of any wind turbine (or structure) over 200ft. Therfore any wind turbine under 200ft would not be included in this data layer. In 2008 the FAA put a focus on wind turbines creating region categories specifically for wind turbines. With this, records for wind turbines before 2008 are less inclusive. The FAA database provides no determination of Wind Turbines that have been built and Wind Turbines that are still in planning stages. Therefore this layer includes Wind Turbines...
This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth,...

These data were compiled to examine patterns of humpback chub (Gila cypha) in western Grand Canyon from just below Havasu Creek at river kilometer (rkm) 253 (Lees Ferry is rkm 0) downriver to Pearce Ferry at rkm 451. These data represent mean daily water temperatures in degrees Celsius from two USGS gaging locations (2005-2016), catches of individual humpback chub in hoop nets (2005-2016), total lengths of individual humpback chub captured in hoop nets during 2014, 2015 and 2016, and the effort (number of seine hauls) and catch of humpback chub in seines (2000-2016) in the Colorado River. These data were collected by research staff from the Grand Canyon, Monitoring & Research Center, Southwest Biological Science...
These data were compiled for a manuscript entitled 'Vital rates of a burgeoning population of Humpback Chub in western Grand Canyon. Objective(s) of our study were to compare survival and growth of humpback chub in western Grand Canyon to that from the more established metapopulation in eastern Grand Canyon that spawns in the Little Colorado River (LCR). These data represent capture histories of fish based on mark-recapture data. These data were collected in eastern Grand Canyon (CR-east study site) and in the western Grand Canyon (CR-west study site). The CR-east reach sites are located at the lower 13.56 rkm of the LCR and in the mainstem of the Colorado River at river kilometers (rkm) 126.2-128.7 (2009-2016)...

These tabular data were compiled to estimate abundance from paired physical capture and antenna detection data in closed, open, and robust design mark-recapture models. These data represent humpback chub capture histories in the Little Colorado River (LCR) and in the juvenile chub monitoring (JCM) reach of the Colorado River in the Grand Canyon, Arizona. The dataset includes multistate capture histories that describe both physical captures and antenna detections. The 'LCR chub' dataset was collected from long-term monitoring efforts by the US Fish and Wildlife Service in the lower 13.56 river km of the LCR (2009-2020), as well as a summer sampling trip conducted by US Geological Survey (2013-2020). Also, the LCR...
