Complex Region Spatial Smoother (CReSS)
(University of St Andrews, 2011) - ReportConventional smoothing over complicated coastal and island regions may result in errors across boundaries, due to the use of Euclidean distances to represent inter-point similarity. The new Complex Region Spatial Smoother ... -
Comparing pre- and post-construction distributions of long-tailed ducks Clangula hyemalis in and around the Nysted offshore wind farm, Denmark : a quasi-designed experiment accounting for imperfect detection, local surface features and autocorrelation
(University of St Andrews, 2011) - ReportWe report a novel technique to model abundance patterns of wintering seaducks in relation to the construction of an offshore wind farm (OWF) based on seven years of aerial survey transect data. Distance sampling was used ... -
A first survey of the global population size and distribution of the Scottish Crossbill Loxia scotica
(2011-06) - Journal articleA survey of Scottish Crossbills Loxia scotica was carried out in 3,506 km2 of conifer woodland in northern Scotland during January to April 2008 to provide the first estimate of the global population size for this endemic ... -
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 ... -
Estimating gopher tortoise abundance through design-based and model-based methods
(2010) - ThesisGopher tortoises are a small land tortoise that inhabit south-eastern United States and are listed as threatened due to habitat loss. They are rather hard to survey, since they occur at low density. This project was based ...
