The objectives of study are to determine the extent to which the presence of Myriophyllum spicatum has altered community structure and the intensity of predator-prey interactions in the Mobile Tensaw Delta (MTD) estuary. This study tested the hypothesis that the presence of Myriophyllum spicatum has triggered a shift in the composition and relative abundances of estuarine predators and their prey as well as trophic exchanges between these predators and their prey. To conduct this evaluation, I compared measures of habitat utilization, community structure, and predator foraging efficiency among the dominant native submerged aquatic vegetation (SAV) species (in terms of areal coverage), Vallisneria neotropicalis and either Heteranthera dubia or Ceratophyllum demersum, found in the MTD and the exotic Myriophyllum spicatum. |
