In situ growth and physiological data from two Antarctic anemone species, Isotealia antarctica and Urticinopsis antarctica at Rothera Research Station (2020-2023)

To further our understanding of Antarctic predator growth and seasonal physiology, field growth rates were measured for two soft-bodied Antarctic anemone benthic predators, Isotealia antarctica and Urticinopsis antarctica, using in situ sampling of anemones on uniquely marked tiles from Rothera Research Station from 2020-2023. Ex situ measurements of oxygen consumption and seven-day faecal output were obtained from recently collected specimens in aquaria and compared between summer and winter. Winter physiological data for Antarctic species are rare, and we tested the hypothesis that generalist feeders or predators continue to feed during the winter. There is a dearth of basic life history and physiological data from Southern Ocean species, particularly from benthic sessile predators. This is an important data gap because species inhabiting the Southern Ocean live in a more temperature stable but seasonally varying environment than temperate and tropical counterparts.

    Statement

    Respirometry data relies on the calibration of PreSens GmBH with SP-PSt3-NAUspots after each respirometry event. These spots are calibrated with 0 % oxygen water and 100 % saturated oxygen water.

    The Sartoritus LA320D balances are calibrated every year and are rotated.



    Losses of data_growth metrics_supplementalS4 (57KB), contain NA''s because author was unable to obtain metrics for each individual anemone for ash free weights because anemone contain high water content and take a long time to dry. Furnace space was limited at Rothera.
