Document Summary
Provide examples of genetic adaptations and acclimatization in arctic organisms. Explain how structure is tightly linked to function at multiple levels of organization in both arctic plants and animals. Analyze data from published research articles to enhance understanding of the impact of climate change on plant or animal function. As with organisms in all environments, arctic plants and animals must be able to carry out critical metabolic processes, exchange materials with their environment, and maintain physiological parameters within a limited range. In this unit we introduce the concept of acclimatization in arctic organisms and we will further explore physiological change on a chronic time scale. First, we will need to review some of the basic processes by which arctic organisms exchange materials with the external environment. Organisms must also balance the ion composition of their internal fluids. Ions are obtained from food or directly from the environment (especially in aquatic animals).
