<br />Appendix II. Summary of population estimates generated within Program CAPTURE for adult
<br />roundtail chub in Westwater Canyon, 1998-2000. Information for comparison within
<br />~ each year of the study among the six estimators used includes the population
<br />estimate (N), 9S% confidence intervals, coefficient of variation (CV), probability of
<br />capture (p-hat), and the model selection criteria.
