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...
This dataset provides morphological and blood-derived physiological data from invasive Burmese pythons (Python bivittatus) captured in Florida. Data were collected on pythons at capture in the field and in varying lengths of time in captivity. Samples were collected immediately at handling (baseline) and 1 hour post-restraint. Physiological data include circulating corticosterone hormone levels, functional immune assays, and blood cell counts. Also included is R code ( Python_captivity_capture_code.R ) to replicate analyses used in the publication "Scales of Stress: Effects of capture and captivity in an invasive snake". For reference, the following data files are relevant to each section of the corresponding manuscript:...

Individual identification is required for investigations that examine population-level changes (e.g., decreased survival, increased disease prevalence) and the mechanisms associated with these changes in wild populations. Such identification generally requires the application of a unique mark, or the documentation of characteristics unique to each individual animal. Marking strategies that minimize handling time (representing stress), and thus minimize impacts to populations, are encouraged from scientific, as well as ethical, perspectives. We used passive integrated transponder (PIT) tagging and photography to individually identify Boreal toads (Anaxyrus boreas boreas) in Rocky Mountain National Park, Colorado...

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...
