About This Book
Authors examine beaver specimens from Utah and conclude that populations are more variable than previously recognized, identifying and naming three previously undescribed subspecies. They present detailed diagnoses including pelage color, skull and dental morphology, and standard measurements for type specimens and ranges, and compare these forms with related subspecies across the region. The paper discusses geographic distribution and cautions that human transplants could alter genetic makeup and distribution, and it specifies color nomenclature and measurement methods used to support taxonomic distinctions.
