Cetacean abundance and distribution in European Atlantic shelf waters to inform conservation and management
(2013-08) - Journal articleThe European Union (EU) Habitats Directive requires Member States to monitor and maintain at favourable conservation status those species identified to be in need of protection, including all cetaceans. In July 2005 we ... -
Design and analysis of line transect surveys for primates
(2010-10) - Journal articleLine transect surveys are widely used for estimating abundance of primate populations. The method relies on a small number of key assumptions, and if these are not met, substantial bias may occur. For a variety of reasons, ... -
Double-observer line transect methods : levels of independence
(2010-03) - Journal articleDouble-observer line transect methods are becoming increasingly widespread, especially for the estimation of marine mammal abundance from aerial and shipboard surveys when detection of animals on the line is uncertain. The ... -
Model-based distance sampling
(2016-03) - Journal articleConventional distance sampling adopts a mixed approach, using model-based methods for the detection process, and design-based methods to estimate animal abundance in the study region, given estimated probabilities of ... -
Spatial models for distance sampling data : recent developments and future directions
(2013-11) - Journal articleOur understanding of a biological population can be greatly enhanced by modelling their distribution in space and as a function of environmental covariates. Density surface models consist of a spatial model of the abundance ...
