Measurements of arsenic in Sonora mud turtles and their food web at Montezuma Well, Arizona 2010-2015

These data were compiled to better understand the geogenic arsenic cycle in a unique natural wetland in central Arizona. The objective of our study was to determine the role of Sonora mud turtles in the arsenic cycle of a simple food web. These data represent the first study to do so even though a previous studies left out turtles as the top predator and consumer. The data were collected at Montezuma Well, a satellite preserve of Montezuma Castle National Monument in Yavapai County, Arizona. These data were collected between 2010 and 2015 from field samples including water, sediments, plants, invertebrates and turtles. These data were collected by employees of the U.S. Geological Survey, Southwest Biological Science Center. These data can be used to better understand the levels of arsenic in various components of the food web at Montezuma Well.
