Program MARK is a Windows-based software application, developed by Gary White (Colorado State University) for the analysis of data from marked individuals. The primary motivation for developing Program MARK was to bring a common interface to the problem of parameter estimation. MARK is now by far the most widely used software application for the analysis of data from marked individuals... Program MARK provides parameter estimates from marked animals when they are re-encountered at a later time. Re-encounters can be from dead recoveries (e.g., the animal is harvested), live recaptures (e.g. the animal is re-trapped or re-sighted), radio tracking, or from some combination of these sources of re-encounters. The time intervals between re-encounters do not have to be equal, but are assumed to be 1 time unit if not specified. More than one attribute group of animals can be modeled, e.g., treatment and control animals, and covariates specific to the group or the individual animal can be..
