Invasive Phragmites Effect On Utah Wetlands Soil Composition, Cecilia Steffen, Rachel Wood, Madison L. Brown
Invasive Phragmites Effect On Utah Wetlands Soil Composition, Cecilia Steffen, Rachel Wood, Madison L. Brown
Library/Life Sciences Undergraduate Poster Competition 2024
Introduction
• Invasive Phragmites australis (referred to as Phragmites), invaded Utah wetlands in the 1980's. Efforts have been made since then to remove Phragmites through various treatments.
• Phragmites outcompetes other wetland plants, causing it to be the dominant species. This is called a monoculture.
• Utah's wetlands are important for many species migrations, filtration, and nutrient cycling.
• How do Phragmites treatments effect soil nutrients and moisture? How do untreated Phragmites wetlands compare to native dominant wetlands?

Theses and Dissertations
An intensive sampling of all ant species encountered on 6 Hawaiian Islands: Big Island, Maui, Oahu, Kauai, Molokai, and Lanai took place between 1988 and 1996. Species presence and absence was recorded at each site. Using remote sensing, variables were added insitu and used throughout my analysis. Species accumulation curves suggest that sampling was comprehensive. There is a significant trend between island area and species richness which validates the Theory of Island Biogeography for invasive species. Islands were found to be significantly nested by area, order, and tourism. Cluster analysis shows a link between elevation, land-use and island, and species …
