Dissertations and Theses
Many rooted macrophytes form a dense canopy on the water surface that is detrimental to aquatic organisms, water quality, navigation, and recreation. Control of invasive macrophytes may be improved when management activities are linked to the plant's biology. The purpose of this research was to evaluate seasonal changes in the morphology, growth rates, allocation patterns and photosynthetic responses of a clonal submersed macrophyte. Egeria densa Planch. (Hydrocharitaceae) is highly invasive in the USA where it forms dense surface canopies in freshwater ecosystems. Using E. densa the following hypotheses were evaluated: (1) flowering stems have reduced capacity for vegetative growth as …
