  • Acoustic and foraging behavior of a Baird’s beaked whale, Berardius bairdii, exposed to simulated sonar 

    Stimpert, Alison; De Ruiter, Stacy Lynn; Southall, Brandon; Moretti, David; Falcone, Erin; Goldbogen, Jeremy; Friedlaender, Ari; Schorr, Greg; Calambokidis, John (2014-11-13) - Journal article
    Beaked whales are hypothesized to be particularly sensitive to anthropogenic noise, based on previous strandings and limited experimental and observational data. However, few species have been studied in detail. We describe ...
  • Annual report on the implementation of Council Regulation (EC) No 812/2004 during 2014

  • An approximate Bayesian method applied to estimating the trajectories of four British grey seal (Halichoerus grypus) populations from pup counts. 

    Lonergan, Michael Edward; Thompson, David; Thomas, Leonard Joseph; Duck, Callan David (2011) - Journal article
    1. For British grey seals, as with many pinniped species, population monitoring is implemented by aerial surveys of pups at breeding colonies. Scaling pup counts up to population estimates requires assumptions about ...
  • Avoidance of wind farms by harbour seals is limited to pile driving activities 

    Russell, Deborah Jill; Hastie, Gordon Drummond; Thompson, David; Janik, Vincent M.; Hammond, Philip Steven; Scott-Hayward, Lindesay Alexandra Sarah; Matthiopoulos, Jason; Jones, Esther Lane; McConnell, Bernie J (2016-05-23) - Journal article
    1. As part of global efforts to reduce dependence on carbon-based energy sources there has been a rapid increase in the installation of renewable energy devices. The installation and operation of these devices can result ...
  • Bayesian sequential tests of the initial size of a linear pure death process 

    Goudie, I.B.J. (2015-05) - Journal article
    We provide a recursive algorithm for determining the sampling plans of invariant Bayesian sequential tests of the initial size of a linear pure death process of unknown rate. These tests compare favourably with the ...
  • Circular designs balanced for neighbours at distances one and two 

    Aldred, R. E. L.; Bailey, R. A.; Mckay, Brendan D.; Wanless, Ian M. (2014-12) - Journal article
    We define three types of neighbour-balanced designs for experiments where the units are arranged in a circle or single line in space or time. The designs are balanced with respect to neighbours at distance one and at ...

    We define three types of neighbour-balanced designs for experiments where the units are arranged in a circle or single line in space or time. The designs are balanced with respect to neighbours at distance one and at ...
  • Complex Region Spatial Smoother (CReSS) 

    Scott Hayward, Lindesay Alexandra Sarah; MacKenzie, Monique Lea; Donovan, Carl Robert; Walker, Cameron; Ashe, Erin (University of St Andrews, 2011) - Report
    Conventional 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 ...
  • Computing in matrix groups without memory 

    Cameron, Peter Jephson; Fairbairn, Ben; Gadouleau, Maximilien (2014-11-02) - Journal article
    Memoryless computation is a novel means of computing any function of a set of registers by updating one register at a time while using no memory. We aim to emulate how computations are performed on modern cores, since they ...
  • Computing in permutation groups without memory 

    Cameron, Peter Jephson; Fairbairn, Ben; Gadouleau, Maximilien (2014-11-02) - Journal article
    Memoryless computation is a new technique to compute any function of a set of registers by updating one register at a time while using no memory. Its aim is to emulate how computations are performed in modern cores, since ...
  • Constructing flag-transitive, point-imprimitive designs 

    Cameron, Peter Jephson; Praeger, Cheryl E. (2016-05-04) - Journal article
    We give a construction of a family of designs with a specified point-partition and determine the subgroup of automorphisms leaving invariant the point-partition. We give necessary and sufficient conditions for a design in ...
  • A critical review of the literature on population modelling 

    Cabrelli, Abigail; Harwood, John; Matthiopoulos, Jason; New, Leslie Frances; Thomas, Len (University of St Andrews, 2009) - Report
    The 2005 report of the National Research Council’s ‘Committee on Characterizing Biologically Significant Marine Mammal Behavior’ proposed a framework, which they called PCAD - Population Consequences of Acoustic Disturbance, ...
  • Decomposition tables for experiments : I. A chain of randomizations 

    Brien, C. J.; Bailey, Rosemary Anne (2009-12) - Journal article
    One aspect of evaluating the design for an experiment is the discovery of the relationships between subspaces of the data space. Initially we establish the notation and methods for evaluating an experiment with a single ...
  • Decomposition tables for experiments : II. Two–one randomizations 

    Brien, C. J.; Bailey, Rosemary Anne (2010-10) - Journal article
    We investigate structure for pairs of randomizations that do not follow each other in a chain. These are unrandomized-inclusive, independent, coincident or double randomizations. This involves taking several structures ...
  • A description of LATTE outputs 

    Marques, Tiago A.; Thomas, Len (University of St Andrews, 2015-10-30) - Report
  • Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis 

    Harris, Catriona M; Sadykova, Dinara; De Ruiter, Stacy Lynn; Tyack, Peter Lloyd; Miller, Patrick; Kvadsheim, Petter; Lam, Frans-Peter; Thomas, Len (2015-11-20) - Journal article
    Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
