as livestock, with wood bison in Alaska and Canada an example of the former, and plains bison in the Canadian and <strong>American</strong> Plains an example of the latter. The jury is probably still out on whether we will manage bison as wildlife, as livestock, or as both in the future, but it is clear that there is a bright role for this animal in an emerging North <strong>American</strong> food system and tradition. Native <strong>American</strong>s are both recovering and restoring their long-established cultural relationship with the <strong>American</strong> bison, and Native <strong>American</strong>s and other non-native North <strong>American</strong>s are finding new ways to relate to this animal in ways that will enhance the conservation of the species. 12 <strong>American</strong> <strong>Bison</strong>: Status Survey and Conservation Guidelines 2010
Chapter 3 Taxonomy and Nomenclature The purpose of naming organisms is to facilitate recognition and communication and to identify patterns and apply practical structure to the natural world. Taxonomy can support the conservation and sustainable use of biological diversity by contributing to identification, assessment, and monitoring programmes (Environment Australia 1998). Taxonomy is also vital for the creation and interpretation of laws, treaties, and conservation programmes because it creates legal identities for organisms (Geist 1991). While it is important to strive for accuracy in taxonomic classification, semantic issues and uncertainty can create substantial management challenges by distracting conservation decision makers from the issues threatening a taxon or biological unit worthy of conservation. Despite the extensive history, and the economic and symbolic importance of bison to North <strong>American</strong> societies, there remains significant confusion and disagreement about bison taxonomy. The issues range from an historical discrepancy over the common name, to ongoing scientific debate over the systematics of the genus, species, and subspecies designations. 3.1 An Historical Misnomer: <strong>Bison</strong> vs. <strong>Buffalo</strong> The bison is not a buffalo. True ‘buffalo’ are native only to Africa (cape buffalo, Syncerus caffer) and Asia (four species of water buffalo, Bubalus spp.). The use of the term buffalo for <strong>American</strong> bison derived perhaps from other languages used by explorers to describe the unfamiliar beast, e.g., bisonte, buffes, buffelo, buffles, and buffilo (Danz 1997; Dary 1989). These terms are similar to bufle and buffe, which were commonly used to refer to any animal that provided good hide for buff leather (Danz 1997). Despite the misnomer, the term ‘buffalo’ has been used interchangeably with “bison” since early explorers first discovered the North <strong>American</strong> species (Reynolds et al. 1982). The term has become entrenched as a colloquialism in North <strong>American</strong> culture and language. Although scientific convention dictates use of ‘bison’, the term ‘buffalo’ persists as an accepted, non-scientific convention for habitual and nostalgic reasons. 3.2 Genus: Bos vs. <strong>Bison</strong> When Linnaeus first classified the bison in 1758 for his 10th Edition of the Systema Naturae, he assigned the animal to Bos, the same genus as domestic cattle (Wilson and Reeder 2005). During the 19th Century, taxonomists determined that Lead Authors: Delaney P. Boyd, Gregory A. Wilson, and C. Cormack Gates there was adequate anatomical distinctiveness to warrant assigning the bison to its own genus (Shaw and Meagher 2000). Therefore, in 1827, C. Hamilton Smith assigned the sub- generic name <strong>Bison</strong> to the <strong>American</strong> bison and the European bison (Skinner and Kaisen 1947). In 1849, Knight elevated the subgenus <strong>Bison</strong> to the level of genus (Skinner and Kaisen 1947). Since then, taxonomists have debated the validity of the genus, some arguing that bison are not sufficiently distinct from cattle, guar, yak, and oxen to warrant a distinct genus (Gardner 2002, personal communication). During the last two decades, as molecular genetic and evolutionary evidence has emerged, scientists have used Bos with increasing frequency. Discrepancies in the genus are reflected in major cataloguing centres and books. For example, the Canadian Museum of Nature (Balkwill 2002, personal communication) and the Smithsonian National Museum of Natural History in its publication Mammal Species of the World (Wilson and Reeder 2005) use <strong>Bison</strong>, while the Royal Ontario Museum (Eger 2002, personal communication) and the Museum of Texas Tech University, in its Revised Checklist of North <strong>American</strong> Mammals North of Mexico (Jones, Jr. et al. 1992; Jones et al. 1997; Baker et al. 2003), have reverted to Bos. The debate over the appropriate genus arises from the conflict between the traditional practice of assigning names based on similar features distinguishable by morphology (the phenetic approach) versus using evolutionary relationships (the phylogenetic approach) (Freeman and Herron 2001; Winston 1999). Systematists develop evolutionary trees by analysing shared derived characteristics (Freeman and Herron 2001; Winston 1999). In this scheme, only monophyletic groups, or clades, which represent all descendants of a common ancestor, are named. A phenetic scheme might assign names to partial clades, or paraphyletic groups, which exclude one or more descendants (Freeman and Herron 2001). Some taxonomists and systematists suggest that the traditional naming system be replaced with a phylogenetic scheme (Freeman and Herron 2001). While not all biologists agree this is prudent, given that a strictly phylogenetic scheme could ignore functionally and ecologically important differences among species (Freeman and Herron 2001), the phylogenetic approach provides some useful insights about evolutionary relationships within the family Bovidae. <strong>Bison</strong> reside in the family Bovidae, subfamily Bovinae, tribe Bovini, which currently contains four genera: Bubalus (Asian water buffalo); Syncerus (African buffalo); Bos (domestic cattle <strong>American</strong> <strong>Bison</strong>: Status Survey and Conservation Guidelines 2010 13
