<a href="woth.txt">woth.txt</a> - Capture history file
for wood thrush example</blockquote><h2>Description</h2><blockquote>
<p>The 'carCJS.r' script requires
the following R packages: boot, coda, deldir, gpclib, maptools, Matrix, R2WinBUGS,
spam, spatstat, spdep, and tripack. The script reads in data; and creates
a base 1-degree ASCII grid ('MAPSgrid.txt'),
a model file for WinBUGS ('spatialcjs.txt'),
and objects needed to run the model in WinBUGS. The script calls WinBUGS and
stores output in an R list called 'out'.
The script also creates objects for creating spatial maps of survival and
residency (as in Fig. 3) within R and writes ASCII grids for making maps with
GIS software outside of R. </p>
<p>The data in 'woth.txt' are capture histories derived from the Monitoring
Avian Productivity and Survivorship (MAPS) program. Included are all records
of adult birds (i.e., ‘after-hatch-year’) of both sexes at stations
where the species is known to breed. Fields in ‘woth.txt’ include:</p>
<ol>
<li>SPEC
– Species 4-letter code. WOTH = wood thrush (<i>Hylocichla mustelina</i>)</li>
<li>STA2
– MAPS station 4-character code. Stations consist of about 10 mist
nets that sample an area of approximately 20 ha. Multiple stations <
1 km apart were considered a single station</li>
<li>BAND
– USGS Bird Banding Laboratory band number</li>
<li>R – Indicates whether predetermined
resident (M) or not (U)</li>
<li>Y1 – Indicator variable
denoting whether captured (1) or not captured (0) in year 1. Y1 corresponds
to 1992, the first year of the study (first year of standardized MAPS protocol)</li>
<li>Y2 – Indicator variable
denoting whether captured (1) or not captured (0) in year 2 (1993)</li>
<li>Y3 – Indicator variable
denoting whether captured (1) or not captured (0) in year 3 (1994)</li>
<li>Y4 – Indicator variable
denoting whether captured (1) or not captured (0) in year 4 (1995)</li>
<li>Y5 – Indicator variable
denoting whether captured (1) or not captured (0) in year 5 (1996)</li>
<li>Y6 – Indicator variable
denoting whether captured (1) or not captured (0) in year 6 (1997)</li>
<li>Y7 – Indicator variable
denoting whether captured (1) or not captured (0) in year 7 (1998)</li>
<li>Y8 – Indicator variable
denoting whether captured (1) or not captured (0) in year 8 (1999)</li>
<li>Y9 – Indicator variable
denoting whether captured (1) or not captured (0) in year 9 (2000)</li>
<li>Y10 – Indicator variable
denoting whether captured (1) or not captured (0) in year 10 (2001)</li>
<li>Y11 – Indicator variable
denoting whether captured (1) or not captured (0) in year 11 (2002)</li>
<li>Y12 – Indicator variable
denoting whether captured (1) or not captured (0) in year 12 (2003)</li>
<li>LAT – Latitude of the MAPS station in decimal degrees</li>
<li>LONG – Longitude of the MAPS station in decimal degrees</li>
<li>CAP – Mean no. of within-year captures per individual at the station</li>
</ol>
<p>Note that although 6,645 birds are included in the woth.txt, only 6,241 of
these birds that were captured for the first time prior to the last year of
the study are read into the data object used in the model.</p>
