The course examines organisms and their abiotic and biotic interactions in natural and human-impacted environments. The importance of temperature, water, and energy are evaluated in the context of physiology and how this impacts distribution patterns. The effects of competition, predation, herbivory, parasitism, mutualism and commensalism on population and community dynamics are examined in detail. An ecosystems approach is explored and discussed in terms of conservation and natural resource management. The significance of evolutionary processes and life history are explored throughout the semester. Prerequisites: Successful completion (C- or better) of BIOL 111 and 112 with labs. Corequisite: BIOL 370L lab, 1 credit hour. Fall.
