Estimating wildlife distribution and abundance from line transect surveys conducted from platforms of opportunity
(University of St Andrews, 2001) - Thesis
Line transect data obtained from 'platforms of opportunity' are useful for the monitoring of long term trends in dolphin populations which occur over vast areas, yet analyses of such data axe problematic due to violation ...
Reconstruction of foliations from directional information
(University of St Andrews, 2007-06) - Thesis
In many areas of science, especially geophysics, geography and meteorology, the data are often directions or axes rather than scalars or unrestricted vectors. Directional statistics considers data which are mainly unit ...
Incorporating measurement error and density gradients in distance sampling surveys
(University of St Andrews, 2007-11) - Thesis
Distance 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 ...
Embedding population dynamics in mark-recapture models
(University of St Andrews, 2009-06-24) - Thesis
Mark-recapture methods use repeated captures of individually identifiable animals to provide estimates of properties of populations. Different models allow estimates to be obtained for population size and rates of processes ...
Using generalized estimating equations with regression splines to improve analysis of butterfly transect data
(University of St Andrews, 2008-06) - Thesis
Surveying animal populations is an important aspect of wildlife management. Distinguishing trend from random fluctuations and quantifying trend are key goals in any analysis. The aim of this thesis is to review analyses ...
A Bayesian approach to modelling field data on multi-species predator prey-interactions
(University of St Andrews, 2006) - Thesis
Multi-species functional response models are required to model the predation of generalist preda- tors, which consume more than one prey species. In chapter 2, a new model for the multi-species functional response is ...
