Supplement 1. The S-Plus (6.0 for Windows [Insightful Corporation, Seattle, Washington, USA]) code used to generate simulated pathways for both examples together with a data set for the sea surface temperature (st) field.

<h2>File List</h2><blockquote> <p><a href="Pathway_code.zip">pathway_code.zip</a> (all files at once) -- a zip containing S-Plus simulation code and a required data set.</p> <p>   <a href="Pathway/S_pathway_code.txt">S_pathway_code.txt</a> </p> <p>   <a href="Pathway/SST.txt">SST.txt</a> </p><p>   <a href="Pathway/readme.txt">readme.txt</a></p> </blockquote><h2>Description</h2><blockquote> The file pathway_code.zip contains the S-Plus code used to simulate movement pathways, a tab-delimited text file of SST (sea surface temperature) random field data required by the pathway simulation, and readme file that describes the code and data set. </blockquote>
