ABSTRACT: State-space models (SSMs) helped NASA complete a successful trip to the moon....and back in 1969. Ames Research Labs developed a SSM fitting algorithm, the extended Kalman filter, which aided navigation and control of the Apollo space capsule. SSMs are models for two time series occurring in parallel: one consisting of an unknown dynamic process and another consisting of imperfect, partial measurements of the process; for example, a time series of the true position of the capsule and a time series of estimates of the position. Such time series pairs are ubiquitous in fish and wildlife management and science, for example, the abundances of a gray whale stock from 1967 through 1997 and shore-based counts of whales. I present a general framework for SSMs as well as a selection of applications to fish and wildlife populations over the past 30 years. Model fitting methods are briefly discussed along with model formulation and evaluation. Entry-level points for fish and wildlife biologists to some of the SSM literature on methodology and applications and to software for fitting SSMs are given.
