Web8 dec. 2024 · Summary. We describe an R package called marked for analysis of mark-recapture data. Currently, the package is capable of fitting Cormack-Jolly-Seber (CJS) models with maximum likelihood estimation (MLE) and Bayesian Markov Chain Monte Carlo (MCMC) methods. In addition, Jolly-Seber (JS) models can be fitted with MLE. Web1 jan. 2009 · Mark–recapture methods were initially developed, and have mostly been used, for studies in which individual animals are physically captured in traps of some kind, … Mark and recapture is a method commonly used in ecology to estimate an animal population's size where it is impractical to count every individual. A portion of the population is captured, marked, and released. Later, another portion will be captured and the number of marked individuals within the … Meer weergeven Typically a researcher visits a study area and uses traps to capture a group of individuals alive.
