This book is a comprehensive presentation of health and diseases in reindeer and caribou, or just Rangifer, a key Circumarctic species with broad social and ecological value. It is an essential reference for anyone interested in the biology and health of wild or semi-domesticated reindeer and caribou, and is more broadly relevant for those with interests in other species of free-ranging and captive cervids. Beginning with a general introduction to Rangifer as a species, it then focuses on Rangifer "health" as a concept and describes the determinants of health at an individual and population level. Chapters cover a range of topics from nutrition and feeding to stress, non-infectious and infectious diseases, meat hygiene, capture and restraint, diagnosis and treatment of health issues, and finally, potential impacts of climate change on health of Rangifer.

Reindeer and Caribou: Health and Disease compiles extensive research and experience-based information on issues ranging from drug doses for chemical immobilization, blood chemistry values, and raising an orphaned calf. In addition, it contains hundreds of high quality colour illustrations that contribute to its value as a diagnostic resource for recognizing various parasites, pathogens and signs of disease, both in live and dead animals. Each chapter is followed by a comprehensive list of references and a list of contact information for all the contributors, identifying world experts in the different areas of health for this circumpolar and fascinating species. This book is compulsory reading and an indispensable resource for anyone dealing with health in reindeer and caribou, including veterinarians, wildlife biologists and managers, reindeer herders/game ranchers, zoological husbandry personnel, and students with wildlife health.

1.1Rangifer tarandus: Classification and Genetic Variation

Knut H. Røed, Steeve Côté, and Glenn Yannic

Intraspecific genetic variation is the most fundamental level of biodiversity, provides the basis for evolutionary change and is crucial for maintaining the ability of species to adapt to new environmental conditions. Knowledge of the genetic variation and structure within reindeer and caribou thus provides essential insights to their future adaptability, including susceptibility to diseases and adaptation to climate change.

1.1.1Classification and Distribution

Reindeer and caribou (Rangifer tarandus) are distributed throughout the northern Holarctic region (Figure 1.1.1); the species is a typical representative of the large mammalian fauna of this region. Reindeer have also been introduced to Iceland (Thorisson 1980) and to the southern hemisphere (e.g. the sub-Antarctic island of South Georgia [Leader-Williams 1988]), where an eradication has recently been conducted. The species belongs to the Cervidae family (the deer family) of ruminant mammals. Further classification and subdivision of Rangifer has been proposed and largely debated (Banfield 1961). Historically, there has been almost as much confusion in vernacular names for the species as in scientific names. The use of two vernacular names for this species – reindeer and caribou – has certainly contributed to the confusion. However, both refer to the same species, and caribou includes all wild specimens in North America, while reindeer refers to both wild and semi-domesticated animals in Eurasia. Domestic animals of Eurasian origin in North America are also called reindeer.

1.1.1.1Subspecies Classification

The subspecies classification of Rangifer has been dominated by a high number of described subspecies without well-defined subspecific characteristics. Prior to the last formal taxonomic revision of Rangifer in 1961, 55 species and subspecies of caribou and reindeer had been described (Banfield 1961). Although outdated, Banfield’s (1961) revision based mainly on craniometrical measurements is still widely used as a guideline for subspecies of reindeer and caribou.

1.1.1.1.1Subspecies in Eurasia

The Eurasian tundra reindeer (R. t. tarandus) is distributed almost continuously across the tundra region and mountain areas of Eurasia (Figure 1.1.1). Most wild and domestic reindeer across Eurasia belong to this subspecies. Today, less than half of the approximately 3–4 000 000 reindeer of Eurasia are wild animals, and in many ...
