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.
