Emergent aquatic macrophyte may serve as refuge, food or mating sites for invertebrates.  The prominence of any one macrophyte, such as the invasive elephant ear (Colocasia sp.), might facilitate the spread of other exotic invasive species that utilize elephant ear for multiple purposes.  Channeled applesnails (Genus: Pomacea) live the majority of their lives on the bottom of slow, shallow water bodies.  However, when ready to lay eggs, female Pomacea climb up emergent structures to deposit large egg clutches that require drying before successfully hatching.  Growth and fecundity of the Texas applesnail, P. insularum, may depend strongly on its interactions with elephant ear as snails also consume stems and leaves.  In laboratory experiments, we demonstrate that juvenile applesnails consume significantly more elephant ear than water hyacinth (Eichhornia).  Furthermore, lab and field studies suggest that females preferentially chose to oviposit on elephant ear stems when other structures were available.  Our current work seeks to discover any relationships between elephant ear as a resource versus as an oviposition site for applesnails across size classes.  With high fecundity often predictive of invasion success for mollusks, bolstered growth or fecundity of applesnails could signal a future invasional meltdown for aquatic systems in the southeast.
