CAPTURE, MARK, POPAN-5, and NOREMARK (White, 1996). The classic
closed-population models of Otis et al. (1978) and some updated estimators
(e.g., jackknife for models M
h
or M
bh
) could be run using the original pro-
gram CAPTURE in PC-DOS. Later, for PC-DOS and the earliest versions of
Windows, an interactive interface for CAPTURE, called 2CAPTURE, was
created (Rexstad and Burnham, 1992), which can still be run using emula-
tors of old Windows versions. Afterward, MRI, another interactive version
of CAPTURE, was created by Landcare Research (New Zealand) and built in
as a module of POPAN-5. MRI also includes an interactive access to JOLLY, a
program for the analysis of open populations based on the Jolly-Seber model
(described in Chapter 8). The last version of MRI was Windows NT execut-
able; thus, it can only be run using Windows emulators. At the Patuxent
Wildlife Research Center (U.S. Geological Survey) website (http://www.mbr-
pwrc.usgs.gov/software/capture.html), there is also a facility for running
CAPTURE statements. The program MARK also includes a menu allowing
access to all the CAPTURE models, including the standard Otis et al.
(1978)
models, Huggins's models, and other approaches for heterogeneity. However,
MARK is not easy to use for a novice, and anyone interested in using it is
advised to take part in a workshop that only addresses this program.
Finally, the program DENSITY is suitable for the analysis of spatially
explicit capture-recapture data (Efford, 2012). This incorporates various
closed-population models for the estimation of population sizes and densi-
ties of animals detected or captured from arrays of traps. See also the work
of Efford et al

(2004) and Efford and Fewster (2013).
