We hope this book will make the bewildering variety of methods for estimat ing the
abundance of animal populations more accessible to the uninitiated and more coherent to …

Summary 1 Methods papers play a crucial role in advancing applied ecology. Counting
organisms, in particular, has a rich history of methods development with many key advances …

Large whales were extensively hunted in coastal waters off Alaska, but current distribution,
population sizes and trends are poorly known. Line transect surveys were conducted in …

Abstract Information on animal distribution and abundance is integral to wildlife conservation
and management. However abundance estimates have not been available for many …

Double-observer line transect methods are becoming increasingly widespread, especially
for the estimation of marine mammal abundance from aerial and shipboard surveys when …

We develop estimators for line transect surveys of animals that are stochastically
unavailable for detection while within detection range. The detection process is formulated …
