Possible Effects of Sampling Biases on Reproduction Rate Estimates for Dolphins in the Eastern Tropical Pacific

Description: From introduction: The purpose of this report is to present a sensitivity analysis on the effects that biased sampling of young calves and lactating females would have on the various estimated life history parameters. This sensitivity analysis provides one measure of reliability of the various estimates. Also, where inconsistencies in the estimates can be identified, this analysis provides one means for evaluating which estimates are likely in error.
