2020 Fall. ; Includes bibliographical references. ; Riparian ecosystems provide essential services including flood mitigation, organic matter and energy, nutrient cycling, and wildlife habitat with their structure and function strongly influenced by fluvial processes and shallow groundwater. Riparian areas across the world have been degraded by land development and the alteration of streamflow by dams, diversions, dikes, and groundwater pumping. Climate change will further stress riparian ecosystems and the Colorado River is predicted to experience the largest decrease in streamflow of the major basins in the western US. Changes in the patterns of stream flow can result in the alteration of plant communities, physical structure, and overall ecosystem functioning. Efforts to understand how plant species are distributed along hydrologic gradients in riparian zones have focused on individual species. The use of vegetation guilds, groups of plants with similar functional traits, may be useful in generalizing plant responses to streamflow alterations across rivers. The identification of trait-based guilds with member species that respond similarly to stressors common along rivers directly links plant performance to environmental processes. The range of traits within a vegetation guild can also help explain how functionally similar species contribute to vegetation structure and heterogeneity that supports habitat for wildlife, including birds that rely on riparian ecosystems for breeding, foraging, nesting, and migration. In Chapter 1, I investigate the relationship between riparian vegetation guilds, vegetation structure, and bird habitat along the Verde River in Arizona. Five woody and seven herbaceous guilds were classified using a suite of functional traits including specific leaf area, potential rooting depth, and seed mass. Bird abundance, diversity, and richness were best predicted by the cover of the tall tree guild dominated by Salix gooddingii and the drought tolerant shrub guild dominated by Prosopis ... |
