Introduction to distance sampling : estimating abundance of biological populations / S.T. Buckland, D.R. Anderson, K. P. Burnham, J.L. Laake, D.L. Borchers and L. Thomas

Includes bibliographic references and index

This book introduces the suite of techniques known as 'distance sampling', so-called because the common theme is the sampling of distances of objects from a line or point. The objects are usually animals or groups of animals ('clusters'), and the primary aim is to estimate their density or abundance in a survey area. In line transect sampling, the sampled distances are the shortest or perpendicular distance from a detected object to the line
