Conservation Genetics of Bull Trout in the Columbia and Klamath River Drainages
Bull trout from the Columbia and Klamath drainages would qualify as separate “species” under the United States Endangered Species Act according to criteria established for anadromous salmonid fishes.
Mating in bighorn sheep: frequent male reproduction via a high-risk “unconventional” tactic
Male traits important in gaining social status and obtaining cooperative consorts with ewes were different and potentially in conflict with those needed to defend against (and practise) coursing, suggesting that sperm competition approximated a fair lottery.
Genetic rescue of an insular population of large mammals
This is the first demonstration, to the authors' knowledge, of increased male and female fitness attributable to outbreeding realized in a fully competitive natural setting and suggests that genetic principles deserve broader recognition as practical management tools with near-term consequences for large-mammal conservation.
Microsatellite evolution in congeneric mammals: domestic and bighorn sheep.
The domestic sheep had greater genetic variation, higher allele-size variances, and larger allele sizes than the wild sheep, and standard measures better distinguished allopatric populations.
Assessing population structure at high levels of differentiation: microsatellite comparisons of bighorn sheep and large carnivores
Despite analytical difficulties at large geographical scales and large genetic divergences, microsatellite data assist management by characterizing historical rates and patterns of dispersal on smaller scales, and by detecting population bottlenecks and regions of particularly high or low historical gene flow.
One of two growth hormone genes in coho salmon is sex-linked.
Sequences of intron C indicate much greater divergence between the X chromosome- specific allele and the Y chromosome-specific allele within coho salmon than between theX chromosomes-specific alleles of coho and the closely related chinook salmon.
Testing for wolf-coyote hybridization in the Rocky Mountains using mitochondrial DNA
The wolf populations in the Rocky Mountain region have not hybridized with coyotes as they have in the Great Lakes region, and mitochondrial DNA was used to evaluate potential gray wolf-coyote hybridization.
Genomic context of paralogous recombination hotspots mediating recurrent NF1 region microdeletion
This work suggests that perfect tracts at recombination hot spots may be a result of gene conversion at sites at which preferential pairing occurs for other, as‐yet‐unknown reasons.
Genetic Structure and Migration in Native and Reintroduced Rocky Mountain Wolf Populations
Gray wolf (Canis lupus) recovery in the Rocky Mountains of the U.S. is proceeding by both natural recolonization and managed reintroduction. We used DNA microsatellite analysis of wolves transplanted
Genetic Variation of Naturally Colonizing Wolves in the Central Rocky Mountains
Recovery of gray wolf (Canis lupus) populations in North America depends on minimizing human-caused mortality and enhancing migration from stable source populations to suitable habitat unoccupied by
