Available in PDF, EPUB and Kindle. Book excerpt: Alaskan caribou (Rangifer tarandus granti) are a valued game species and a key grazer in Alaska's terrestrial ecosystem. Caribou herds, defined by female fidelity to calving grounds, are management units. However, the extent to which herds constitute genetic populations is unknown. Historical fluctuations in herd size, range, and distribution suggest periods of contact and isolation between herds. Likewise, historical contact between caribou and introduced domestic reindeer (R.t. tarandus) created opportunities for hybridization, but its extent is not known. I conducted an interdisciplinary study to understand how historical processes influence genetic identity and population structure of caribou and reindeer. Interviews with herders and hunters in Barrow, Alaska, revealed that many reindeer migrated away with caribou in the 1940s despite herder efforts to prevent mixing. Local observations of reindeer-like animals in caribou herds today suggest feral reindeer may survive and interbreed. Using genetic analysis of North Slope caribou and Seward Peninsula reindeer (n = 312) at 19 microsatellite loci, I detected individuals with hybrid ancestry in all four caribou herds and in reindeer. Selective hunting of reindeer-like animals, along with herd size and natural selection, may remove reindeer from caribou herds over time. I used genetics as well to describe caribou population structure and determine how it is influenced by geography, historical demography, and ecotypes. I found that Alaskan caribou from 20 herds (n = 655) are subdivided into two genetic clusters: the Alaska Peninsula and the mainland. Alaska Peninsula herds are genetically distinct, while many mainland herds are not. I hypothesize that Alaska Peninsula herds have diverged due to post-glacial founder effects and recent bottlenecks driven by constraints to population size from marginal habitat and reduced gene flow across a habitat barrier at the nexus of the peninsula. I hypothesize that mainland herds have maintained genetic connectivity and large effective population size via range expansions and shifts over time. However, I find evidence that herds of different ecotypes (migratory, sedentary) can remain differentiated despite range overlap. Genetic evidence provides information for herd-based management, while also demonstrating the importance of spatial connectivity of herds and their habitats over the long-term.

Download or read book Caribou Herds of Northwest Alaska 1850 2000 written by Ernest S. Burch Jr. and published by University of Alaska Press. This book was released on 2012-09-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his final, major publication Ernest S. “Tiger” Burch Jr. reconstructs the distribution of caribou herds in northwest Alaska using data and information from research conducted over the past several decades as well as sources that predate western science by more than one hundred years. Additionally, he explores human and natural factors that contributed to the demise and recovery of caribou and reindeer populations during this time. Burch provides an exhaustive list of published and unpublished literature and interviews that will intrigue laymen and experts alike. The unflinching assessment of the roles that humans and wolves played in the dynamics of caribou and reindeer herds will undoubtedly strike a nerve. Supplemental essays before and after the unfinished work add context about the author, the project of the book, and the importance of both.
