Density estimation implications of increasing ambient noise on beaked whale click detection and classification
(University of St Andrews, 2010) - ReportAcoustic based density estimates are being increasingly used. Usually density estimation methods require one to evaluate the effective survey area of the acoustic sensors, or equivalently estimate the mean detection probability ... -
Designing a shipboard line transect survey to estimate cetacean abundance off the Azores Archipelago, Portugal
(2008) - ThesisManagement schemes dedicated to the conservation of wildlife populations rely on the effective monitoring of population size, and this requires the accurate and precise estimation of abundance. The accuracy and precision ... -
Distance software: design and analysis of distance sampling surveys for estimating population size
(2010) - Journal article1. Distance sampling is a widely used technique for estimating the size or density of biological populations. Many distance sampling designs and most analyses use the software Distance. 2. We briefly review distance sampling ... -
Estimating the Barents Sea polar bear subpopulation size
(2009-01) - Journal articleA large scale survey was conducted in August 2004 to estimate the size of the Barents Sea polar bear subpopulation. We combined helicopter line transect distance sampling surveys in most of the survey area with total counts ... -
Estimation bias under model selection for distance sampling detection functions
(2017-05-26) - Journal articleMany simulation studies have examined the properties of distance sampling estimators of wildlife population size. When assumptions hold, if distances are generated from a detection model and fitted using the same model, ... -
Incorporating measurement error and density gradients in distance sampling surveys
(University of St Andrews, 2007-11) - ThesisDistance sampling is one of the most commonly used methods for estimating density and abundance. Conventional methods are based on the distances of detected animals from the center of point transects or the center line ...
