Antarctic sea anemone distribution, abundance and relationships with habitat composition, community structure and anthropogenic disturbance
Understanding the distribution, abundance and habitat preferences of species in the SouthernOcean provides a foundation for assessing the impacts of environmental change and anthropogenicdisturbance on Antarctic ecosystems. In near-shore waters at Casey and Davis Stations, photoquadratsurveys were u...

Understanding the distribution, abundance and habitat preferences of species in the SouthernOcean provides a foundation for assessing the impacts of environmental change and anthropogenicdisturbance on Antarctic ecosystems. In near-shore waters at Casey and Davis Stations, photoquadratsurveys were used to determine sea anemone distribution and abundance, habitat preferences,associations with other species and the impact of human disturbance on sea anemone distribution.Two distinct sea anemone morphotypes were found in this study: large sea anemones that requirehard substrate for attachment and small, burrowing sea anemones found in muddy sediment.

The large sea anemones were associated with a diversecommunity of epibenthic species found in rocky habitats.

At Casey Station, seaanemones were more abundant in habitats adjacent to a former waste disposal site than at controlsites.
