Minimum daily air temperatures (1999 to 2001) and minimum and maximum daily water temperatures next to egg masses (2001) during embryogenesis for Anaxyrus canorus at various breeding sites near Tioga Pass

We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. From 1999 to 2001, we deployed Optic StowAway Temperature loggers (Onset Computer Corporation; Bourne, Massachusetts, USA) to measure minimum daily air temperatures at various breeding sites during embryogenesis for A. canorus. These measurements enabled us to determine relations between air temperatures at individual breeding sites relative to air temperatures measured at the automated weather station in Dana Meadows (DAN) in the heart of our study area. We measured air temperatures [...]
