INDIVIDUAL BASED STATISTICAL METHODS FOR DNA-PROFILES WITH APPLICATION TO MANAGEMENT OF MARINE RESOURCES

Tildelt: kr 0,13 mill.

DNA registers are rapidly being built up for many wildlife species. Data may result from harvesting operations or by designed scientific sampling, or a combination of the two. DNA profiles provide information about the relationship between individuals in the sample, and hence information about the demographic structure of the population. Such studies are conducted both for terrestrial and aquatic species, but are particularly useful for marine species which are difficult to observe. The identification of closely related individuals in a sample constitutes a statistical challenge, as commonly used DNA-profiles do not determine the type of relationship with certainty. There is a growing literature in this field, but there still is a need for basic research. The two main components of project will be abundance estimation of minke whales using the close-kin approach of Skaug (2001) and estimation of variation in reproductive success from DNA-register data. Under both activities the use of single nucleotide po lymorphisms (SNP) markers will be investigated to prepare for the growing amount of SNP data that will be available in the near future.
