Invasion Ecology: Effects of Habitat Alteration on the Survival of an Exotic Species

Dataset extent

The Dr. John Valentine Lab at the Dauphin Island Sea Lab reports the findings of a three year study conducted in the upper reaches of the Mobile Bay Estuary and the lower Mobile Tensaw Delta (MTD). This study evaluates, to the extent possible, that variability in disturbance intensity arising from hydrological modification of estuarine hydrology determines the abundance and distribution of one of the most common exotic submerged aquatic vegetation (SAV) species found in the area, Eurasian milfoil (Myriophyllum spicatum). Prior to this study, no one has experimentally evaluated the impacts of habitat forming exotic SAV species on native SAV species in the Northern Gulf of Mexico. Furthermore, none have evaluated the extent to which natural disturbances or variations in local hydrography control the spread of these exotics in estuarine waters.
