"Sensitivity of an alpine watershed to climate change: Interactions among stream hydrology, DOC, heavy metals, and UV radiation."

The ability to tolerate disturbance is a defense strategy that minimizes the effects of damage to fitness and is essential for sustainability of populations, communities and ecosystems. Despite the apparent benefits of tolerance there may be an associated cost that results in a deficiency of a system to respond to additional disturbances. Aquatic ecosystems are often exposed to a variety of natural and anthropogenic disturbances and the effects of these compound perturbations are not well known.  In this investigation I examine whether tolerance to one stressor, metals, results in a cost of increased sensitivity to an additional stressor, Ultraviolet-B (UV-B) radiation under the umbrella of climate change.
