Abstract Small numbers of domestic yak (Bos grunniens) were imported to North America in the late 19th century indirectly from the Qinghai-Tibetan Plateau. Coat color of yak is of interest for fiber production, aesthetics, and as a potential indicator of recent hybridization with cattle. North American yak are classified into 3 major coat color patterns depending upon the presence and extent of white markings. They are further classified by nose pigmentation (black or gray). The aim of this study was to identify loci involved in white patterning and nose pigmentation of North American yak. Genotyping by mass spectrometry of markers identified through Sanger and whole-genome sequencing revealed a 388 kb haplotype of KIT associated in a semi-dominant manner with white coloration in this population of yak. This KIT haplotype is similar to both a haplotype found in white-faced Chinese yak and to haplotypes found in cattle but is divergent from other Bos species such as bison, gaur, and banteng. Melanocortin 1 receptor (MC1R) was implicated as a dominant determinant of black nose color with a single haplotype containing 2 missense mutations perfectly associated with the phenotype. The MC1R haplotype associated with black nose pigment is also similar to cattle haplotypes. No cattle studied, however, shared either of the 2 haplotypes associated with color in yak, suggesting these alleles were introgressed into yak before they were imported to North America. These results provide molecular insight into the history of North American yak and information from which breeders can determine possible color outcomes of matings.

Two new species of the subterranean amphipod genus Stygobromus are described from groundwater habitats in Siberia: Stygobromus mikhaili n. sp. from a spring in the Central Altay Mountains and Stygobromus anastasiae n. sp. from two non-freezing springs in South Pribaikalye in the Irkutsk area. Additional taxonomic details of the previously described S. pusillus (Martynov) from Teletskoye Lake, also in Central Altay, are illustrated based on syntype material. Utilization of SEM has revealed a tiny structure on antenna 2 that appears to be a new character, and may prove useful in future analyses. Descriptions of the two new species raise the total number of described species in the genus Stygobromus to 134, but four or possibly five have been found in the Palearctic region outside North America. However, it is likely that continued exploration of subterranean groundwater habitats in Siberia and other parts of the Palearctic will reveal additional new species of Stygobromus and provide more insight into the origin and geographic distribution of this large, northern hemisphere, subterranean freshwater amphipod genus. Careful evaluation of taxonomic affinities of the new species and comparison with previously described congeners should provide further insight into the biogeographic history of Stygobromus.

This article provides a comparative overview of the history of museums in Europe and North America, from their origins to their most recent postmodern transformations. It highlights the very unique evolution of museums in North America compared to their European counterparts due to their emphasis on leisure and their strong ties with local communities. It also shows how museums in Quebec, and in Canada as a whole, tend to focus more on ideas than those in Europe, the Musée de la civilisation being a prime example. North American museums have demonstrated the capacity to adapt to the specific needs of communities by being open and flexible institutions capable of preserving heritage, speaking to citizens, and transmitting − or simply bringing life to − past and present cultures.

Species from the crested wheatgrass (Agropyron spp.) complex have been widely used for revegetation and grazing on North American rangelands for over 100 years. Focused crested wheatgrass breeding has been ongoing since the 1920s. These efforts resulted in the development of 18 cultivars adapted to western USA and Canadian growing conditions. These cultivars establish rapidly, persist, and provide soil stabilization and a reliable feed source for domestic livestock and wildlife. To address ecological concerns and increase rangeland agriculture efficiency, crested wheatgrass breeding requires new emphases and techniques. This review covers the history of crested wheatgrass breeding and genetics in North America and discusses emerging methods and practices for improvement in the future.

The interplay between modes of speech and the demographical, geographical, social, and political history of Britain's North American colonies of settlement influenced the linguistic evolution of colonial English speech. By the early to mid-eighteenth century, regional varieties of English emerged that were not only regionally comprehensible but perceived by many observers as homogeneous in contrast to the deep dialectical differences in Britain. Many commentators also declared that Anglophone colonial speech matched metropolitan standard English. As a result, British colonials in North America possessed a national language well before they became “Americans.” This shared manner of speech inadvertently helped to prepare them for independent American nation-hood.

Today’s political map of North America took its basic shape in a continental crisis in the 1860s, marked by Canadian Confederation (1867), the end of the U.S. Civil War (1865), the restoration of the Mexican Republic (1867), and numerous wars and treaty regimes conducted between these states and indigenous peoples through the 1870s. This volume explores the tumultuous history of North American state-making in the mid-nineteenth century from a continental perspective that seeks to look across and beyond the traditional nation-centered approach. This introduction orients readers by first exploring the meaning of key terms—in particular sovereignty and its historical attachment to the concept of the nation state—and then previewing how contributors interrogate different themes of the mid-century struggles that remade the continent’s political order. Those themes fall into three main categories: the character of the states made and remade in the mid-1800s; the question of sovereignty for indigenous polities that confronted the European-settler descended governments of Canada, Mexico, and the United States; and the interaction between capitalist expansion and North American politics, and the concomitant implications of state making for sovereignty’s more diffuse meaning at the level of individual and group autonomy.

This article explores the history of vínarterta, a striped fruit torte imported by Icelandic immigrants to North America in the late nineteenth century and obsessively preserved by their descendants today. When roughly 20–25 percent of the population of Iceland relocated to North America between 1870 and 1914, they brought with them a host of culinary traditions, the most popular and enduring of which is this labor-intensive, spiced, layered dessert. Considered an essential fixture at any important gathering, including weddings, holidays, and funerals, vínarterta looms large in Icelandic–North American popular culture. Family recipes are often closely guarded, and any alterations to the “correct recipe,” including number of layers, inclusion or exclusion of cardamom or frosting, and the use of almond extract, are still hotly debated by community members who see changes to “original” recipes as a controversial, even offensive sign of cultural degeneration. In spite of this dedication to authenticity, this torte is an unusual ethnic symbol with a complex past. The first recipes for “Vienna torte” were Danish imports via Austria, originally popular with the Icelandic immigrant generation in the late nineteenth century because of their glamorous connections to continental Europe. Moreover, the dessert fell out of fashion in Iceland roughly at the same time as it ascended as an ethnic symbol in wartime and postwar North American heritage spectacles. Proceeding from recipe books, oral history interviews, memoirs, and Icelandic and English language newspapers, this article examines the complex history of this particular dessert.

Abstract—Despite being dominant elements of understory communities in the coniferous forests of western North America, phylogenetic relationships among bilberries (Vaccinium section Myrtillus) remain unresolved. Morphological delimitation among most western bilberry species is tenuous, and traditionally employed molecular sources of phylogenetic information have yielded insufficient variability. Moreover, these species are hypothesized to have undergone extensive introgression. We used RADseq data analyzed with maximum likelihood species tree estimation and Patterson’s D-statistic analyses to examine the influence of introgression on relationships among Vaccinium myrtillus, V. scoparium, and V. cespitosum. Additionally, we used these data to assess whether the populations of V. myrtillus disjunct between North America and Eurasia are monophyletic and should continue to be recognized as conspecific. Significant genome-wide introgression, as determined through D-statistic analyses, was detected between North American samples of V. myrtillus and V. cespitosum, and to a lesser extent, between V. myrtillus and V. scoparium. No significant D-values were detected between V. scoparium and V. cespitosum. Accessions of Vaccinium myrtillus from Eurasia and North America were recovered as non-monophyletic, prompting our proposed resurrection of V. oreophilum for North American material. The long-assumed sister species relationship between V. oreophilum and V. scoparium was not recovered in our analysis. Instead, V. oreophilum and V. cespitosum were inferred to be sister taxa. This study reveals considerable introgression detectable in the evolutionary history of western North American bilberries and demonstrates the utility of RADseq data to resolve species level relationships in groups that undergo reticulate evolution such as Vaccinium.
