Identification of Novel Single-Nucleotide Polymorphisms in Chinook Salmon and Variation among Life History Types
—Single-nucleotide polymorphisms (SNPs) are simple base substitutions or small indels in otherwise conserved regions of nuclear or mitochondrial DNA. Assays detecting these genetic markers have been a powerful tool for conserving and managing fish populations. In nonmodel species, however, available DNA sequence data are limited and inventive techniques must be employed in screening for SNPs. I...
متن کاملGenetic Variation and Structure of Chinook Salmon Life History Types in the Snake River
—We evaluated 25 inland populations of Chinook salmon Oncorhynchus tshawytscha in the Snake River with 13 microsatellite loci to test for contemporary genetic differentiation at three scales: between life history types, among regions within life history types, and among populations within regions. The genetic distance and diversity of natural Chinook salmon populations were also contrasted with...

15 صفحه اولsecuritization of mortality risks in life annuities
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
