Nutrient Conservation Trait Responses Of Low Resource Adapted Chaparral Shrubs To Increased Resource Availability, Reina Lee Nielsen
Nutrient Conservation Trait Responses Of Low Resource Adapted Chaparral Shrubs To Increased Resource Availability, Reina Lee Nielsen
Masters Theses
Traits that increase mean nutrient retention times are essential to plant performance in low resource environments, where multiple stressors (low water and nutrients) are present. Although physiological responses to either water or nutrient stress are well understood, fewer studies have investigated the interaction of these stressors from a phylogenetically-controlled, whole-plant perspective. This research focused on three, phylogenetically-controlled pairs of shrubby evergreen species from the California chaparral that either grow on or off serpentine soils, which differ in nutrient availability. Using greenhouse and field studies, the responses of these plants to altered water and nutrient availability were evaluated. The greenhouse study …
