Document Summary
Evolution: the study of both adaptive and non-adaptive change over time in populations, the origin and extinction of species, and the relationships among living things. Ecology: the study of interrelationships between organisms and both living (biotic) and non-living (abiotic) components of their environments. Physiology: the study of organism structure and function, including homeostasis and encompassing cells, tissues, organs, and body systems. Biological impacts: biodiversity changes, disease, migration. Political and economic impacts: artic sovereignty, natural resources, environmental policy. Artic plants and animals have lived in the artic ecosystem for thousands of year. They must cope with temperature change on many different time scales. Adjustment by an individual organism to chronic stress. Physiological processes or structures change to function more optimally under new. Change is reversible, and may even be repeated. Air temperature tissue damage due to temperature extremes. Wind speed high wind desiccation, wind damage. Snow cover shelter from the wind and insulates temperature extremes.
