dc.description.abstractThe rapid melting of glaciers and loss of sea ice will result in changes in habitat conditions that may drive substantial changes in biodiversity. In order to bioassess the changing polar ecosystem and evaluate biologicalconservation, pelagic ciliate communities at different taxonomic resolutions were studied at five habitats in the Amundsen Sea during the austral summer from December 2010 to January 2011. Distinctive spatial patterns were observed in the communities among the five habitats (oceanic areas, transitional areas, polynyas, edges of glaciers,and edges of sea ice) in response to environmentalvariability (e.g., temperature, salinity, chlorophyll a, and nutrients). The distributions in the numbers of differenttaxonomic levels and of three biodiversity indices (Shannon-Wiener H0, Pielou's J0, and Margalef D) also revealed clear spatial variability with the maximum mean species number and indices in the polynya and maximum genus and family numbers in the transitional area. The presence/absence of data at taxonomic resolutions up to the family level provided sufficient information to evaluate the ecologicalpatterns of pelagic ciliate communities and could accurately reflect habitat variations.The k-dominance curves illustrated clearly that maximum diversity waspresented in the polynya at the species level and in the transitional area at the genus and family level. We suggestthat the diversity at higher taxonomic resolutions should be considered more in future monitoring. Our findings provide basic data and an approach toward answering important questions about biological conservation, especially the biodiversity at various taxonomic resolutions in response to the increasing climate changes in polar ecosystems.-
