Day's research uses physiological and ecological approaches to determine how environmental factors influence the performance and distribution of plants and how these influences in turn alter the productivity and nutrient cycling at the whole-community or ecosystem level. Through field work and laboratory experiments, he investigates how environmental factors such as high levels of ultraviolet and visible light, extreme temperatures, and water stress limit plant performance under natural conditions. His concern is how these factors alter key processes such as photosynthesis, respiration, growth, reproduction, productivity, and nutrient cycling.
