Declining amphibian populations: The pitfalls of count data in the study of diversity, distributions, dynamics, and demography


Schmidt, B R (2004). Declining amphibian populations: The pitfalls of count data in the study of diversity, distributions, dynamics, and demography. Herpetological Journal, 14(4):167-174.

Abstract

Most data used in the study of the demography, dynamics, distributions, diversity, and declines of amphibians are count data that are not adjusted for detection probabilities, which are generally variable and low. Such unadjusted count data are unreliable for understanding amphibian ecology, amphibian declines, or when developing conservation and management strategies. In the future, detection probabilities should be estimated and counts adjusted accordingly. This could be achieved by using capture-mark-recapture, distance sampling or novel Bayesian methods.
