Summary

These data were compiled as part of an ecological study of Sonora Mud Turtles and their interaction with non-native turtles at Montezuma Well in Yavapai County, Arizona. The data consist of observations and measurements of individual turtles captured during the study, and support analyses of population size and trends, general condition and health of the turtles, and female reproduction. Principal investigators for the study were Phil Rosen (1983 data), Matthew Malone and Steve Garber (1999 data) and Jeff Lovich and Charles Drost (data from 2007 through 2015). This dataset provides detailed capture data, measurements, and female reproductive status for the Sonora Mud Turtle population at Montezuma Well, which should be useful for comparisons [...]

Purpose

The purpose of these data are to support and document calculations and estimates of population size, and reproductive rates of female Sonora Mud Turtles over the study period. Non-native turtles (primarily Pond Sliders) were removed from Montezuma Well starting in 2007, so population size was calculated simply from the decrease of non-native turtles, to zero in 2013 (i.e., capture of the last non-native turtle). Population size for Sonora Mud Turtles was calculated using mark-recapture estimators of the individually marked turtles. Number of eggs was recorded for most female turtles examined, but the data were reported as simply gravid (eggs present) or not gravid (no eggs) for purposes of the manuscript.
