When Offered:Spring. Alternate years The study of the relationships among individual organisms and the biotic and abiotic environments. Structure/function relationships will be emphasized throughout the course. Topics to be covered include: energy budgets; gas exchange by plants and animals; resource acquisition; water relations; and morphological, physiological and behavioral adaptations to environmental selection pressures. Lab will cover techniques of measuring gas exchange in both animals and plants; nutrient uptake; water relations; foraging efficiencies and physiological optima; and techniques in microclimate measurement. Prerequisites: BIO 3302 (Ecology) and either BIO 3301 (Human Systems Physiology) or BIO 5555. Lecture three hours, laboratory three hours.
