The proposed research has two main objectives: (1) To further investigate the interactions between the ecologically dominant large macrophytes, filamentous epi/endophytes, and mesograzers and (2) To determine the nature of interactions between mesograzers and sessile invertebrates.

Broader impacts include involvement of undergraduates, including minorities, in research; training of graduate students, and continuation of the highly successful UAB IN ANTARCTICA interactive web program (two time recipient of awards of excellence from the US Council for Advancement and Support of Education). The researchers also will share their scientific endeavors with teachers, K-12 students, and other members of the community at large while in residence in Antarctica. In addition, the investigators will request the participation of a PolarTREC teacher."
