Animal Movement - Mobility Data - page 286

from physics to biology in order to develop a more quantitative understanding of
animal movement. Okubo ( 1980 ) mainly uses an Eulerian approach by studying
the “average” movement. For a discussion of the differences between Eulerian
and Lagrangian approaches, see. Smouse et al. ( 2010 ). In Alt and Hoffman
( 1990 ), one can find a very useful glossary, many examples of studies on solitary
and social organisms, descriptions of simulation methods, and a first mention
of Levy walk in relation to animal movement. The topic by Turchin ( 1998 )
is the best reference text on the subject. It deals with both data analysis and
modeling and presents a wide review of the literature. The beginner is suggested
to start with this topic. Gould and Gould ( 2012 ) are a useful reference for
animal navigation. Nathan et al. ( 2008 ) introduced “movement ecology” theory.
Hierarchical resource selection was originally developed by Johnson ( 1980 ). The
presence of Levywalks in nature and themethods to discriminate Levywalks and
Brownian motion have determined much controversy. A short presentation of
this debate can be found in Smouse et al. ( 2010 ), and a more detailed discussion
is given by Viswanathan et al. ( 2011 ). Finally, a comprehensive description of
recent technology, data management, and analysis issues in the study of animal
movement, mainly driven by the use of GPS-based devices, is offered in the
Thematic issue of Cagnacci et al. ( 2010 ). The study on elks is from Fryxell
et al. ( 2008 ). The experimental studies on fallow deer can be found in Focardi
et al. ( 2009 ), and information about biologgers in relation to animal movement
studies is described by Tomkiewicz et al. ( 2010 ). Urbano et al. ( 2010 ) is a useful
reference for animal movement databases.
