Project Title: Use of Genetic Markers to Identify Individuals in Capture-recapture Studies

Principal Investigator: Ken Burnham

Funding Agency: Colorado Division of Wildlife

Objectives: Monitoring habitat use, movement patterns, survival and reproduction of lynx.

Introduction: Ninety-six lynx were reintroduced in Colorado in an effort to establish a viable population following their expiration from the state. We are currently monitoring habitat use, movement, survival, and reproduction of radio collared individuals. Recent developments in genetics allow individual identifications from small amounts of DNA such as a few cells at the root of a hair. If the entire genome could be examined error free, the identity of an individual would be certain. Due to practical considerations, only a small portion of the genome is examined. Therefore, identity is uncertain. The project will develop a way to quantify the uncertainty in identification from DNA fingerprints, and a way will be developed to incorporate uncertain identification in capture-recapture models. The DNA capture-recapture methods will be applied to lynx in Colorado.

Progress: An extension to the closed population and robust design capture-recapture models has been developed. A method for using scat based DNA sampling is in progress. All hair and blood samples have been analyzed for microsatellite genotypes.
