Transmissible cancers are clonal lineages of neoplastic cells able to infect multiple hosts, spreading through populations in the environment as an infectious disease. Transmissible cancers have been identified in Tasmanian devils, dogs, and bivalves. Several lineages of bivalve transmissible neoplasias (BTN) have been identified in multiple bivalve species. In 2019 in Puget Sound, Washington, USA, disseminated neoplasia was o...

Inferring the genomic basis of local adaptation is a long‐standing goal of evolutionary biology. Beyond its fundamental evolutionary implications, such knowledge can guide conservation decisions for populations of conservation and management concern. Here, we investigated the genomic basis of local adaptation in the Coho salmon ( Oncorhynchus kisutch ) across its entire North American range. We hypothesized that extensive spat...

The major histocompatibility complex ( MHC ), an important component of the vertebrate immune system, provides an important suite of genes to examine the role of genetic diversity at non‐neutral loci for population persistence. We contrasted patterns of diversity at the two classical MHC loci in sockeye salmon ( O ncorhynchus nerka ), MHC class I ( UBA ) and MHC class II ( DAB ), and neutral microsatellite loci across 70 popul...

Nest site fidelity and serial polyandry were examined in lingcod, Ophiodon elongatus , a teleost fish in which the nest‐guarding male parent invests more heavily in parental care than the elusive female parent. Lingcod parental and progeny genotypes were established for fish spawning on a 200 m 2 section of Snake Island reef, British Columbia in two successive years to evaluate male and female mate choice (monogamy or polygamy...
