Occupancy Estimation and Modeling

Cutting-edge information on improving ecological statistics and estimation

Examines models for analyzing presence/absence data in occupancy measurement, and explores its importance in accurate population estimation. Using multiple models, this title addresses the problem of imperfect detectability, and provide flexible means of analysis to address the issue.Occupancy Estimation and Modeling is the first book to examine the latest methods in analyzing presence/absence data surveys. Using four classes of models (single-species, single-season; single-species, multiple season; multiple-species, single-season; and multiple-species, multiple-season), the authors discuss the practical sampling situation, present a likelihood-based model enabling direct estimation of the occupancy-related parameters while allowing for imperfect detectability, and make recommendations for designing studies using these models.
