Humpback chub spring and fall capture histories in the Little Colorado River, 2009-2019

These data were compiled to examine rates of skipped migration in adult humpback chub that spawn in the Little Colorado River (LCR). These data include mark-recapture information from the lower 13.56 kilometers of the LCR and from the Colorado River, from river kilometer 105.5-145.7 downstream of Glen Canyon Dam. Data also include detections from a multiplexer array (MUX) that is located in the LCR and from submersible PIT tag antennas that are deployed in parts of the Colorado River. These data are capture histories that include both spring and fall sampling events that occurred between spring 2009 and spring 2019. Capture histories can include information about size (small adults being 200-249mm total length and...

Injury and abnormality data for southwestern pond turtles (Actinemys pallida) from 3 sites along the Mojave River, California from separate surveys in 1998-1999 and 2017-2019

These data were compiled to assess the size, structure, and health of various populations of Actinemys pallida along the length of the Mojave River. Objective(s) of our study were to determine the extent of injuries and abnormalities within our Actinemys pallida populations (including statistical analyses comparing injuries with turtle sex and size) and estimate the cause(s) of the injuries and abnormalities. These data represent injuries and abnormalities from the effects of physical hazards encountered by turtles in their habitats. These data were collected in the Mojave Desert of California at three separate study sites along a length of the Mojave River in San Bernardino County between May 1998–October 1999...

Rainbow trout reproduction data from 3 sampling trips (2018-2019) within Glen Canyon, AZ

These data were compiled to describe population reproductive structure of rainbow trout in the Colorado River downstream of Glen Canyon Dam, Arizona. Objective(s) of our study were to describe the population on reproductive structure of the rainbow trout population in Glen Canyon on the Colorado River and evaluate the accuracy of nonlethal methods (manual expression and ultrasonography) for assigning sex and reproductive phase. These data represent samples collected in 3 sampling trips fall in October to November 2018, February 2019, and April 2019. These data were collected in Glen Canyon, from Glen Canyon Dam to Lees Ferry on the Colorado River. Specifically, we sampled three reaches within Glen Canyon to represent...
