ABSTRACT
This chapter discusses the importance of nutrition and adaptation to the seasonally changing availability and quality of reindeer and caribou diets, and the subsequent importance this may have for Rangifer health and performance. The topic includes the seasonal diet and nutrient intake, the function of the gastrointestinal tract, nutritional needs, deficiencies and starvation and the effect of nutrition on growth, reproduction and survival, with implications for population dynamics and management.
