Accounting for animal density gradients using independent information in distance sampling surveys

Marques, Tiago A.; Buckland, Stephen T; Bispo, Regina; Howland, Brett

Description

Distance sampling is extensively used for estimating animal density or abundance. Conventional methods assume that location of line or point transects is random with respect to the animal population, yet transects are often placed along linear features such as roads, rivers or shorelines that do not randomly sample the study region, resulting in biased estimates of abundance. If it is possible to collect additional data that allow an animal density gradient with respect to the transects to be...[Show more]
