Summary

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. We assessed the extent of annual mortality among embryos of A. canorus and Pseudacris regilla variously among breeding sites and years by measuring hatching success in as many individual egg masses as possible, given logistical constraints, at sites we surveyed annually from 1996 to 2000. We visually evaluated each individual embryo in an egg mass in situ while kneeling alongside it immediately before, at, or very soon after hatching (when individual capsules remained from hatched [...]

Purpose

We used these data to help us evaluate the effects of potential exposure to freezing and UV-B on embryos of these species in our study area. Other researchers could use them to address various ecological questions related to fitness, reproduction success, recruitment, and natural history, among other topics, for A. canorus (especially) and P. regilla in our study area or elsewhere.
