Title Developing methods to estimate parameters associated with animal population


Project Description This project involves research on field and statistical methods for estimating parameters relevant

to animal population dynamics including development of capture-recapture models to estimate

population size, population rate of increase, movement rate, survival rate, transition probabilities

among different individual states or conditions, total number of transiets in a population, probability

that an animal is a temporary emigrant, number of animals passing through a migration stopover

location, etc. Combination studies involving both capture-recapture data and data from band

recoveries, ancillary resightings, and radio-telemetry permit estimation of additinal parameters

relating to fidelity and both permanent and temporary emigration. In addition, methods will be

developed to estimate abundance, density, and rate of population increase based on animal


Keywords abundance, animal population dynamics, density, estimation, modeling, survival rate,
