冰川的迅速融化和海冰的减少将导致栖息地条件的变化，从而可能导致生物多样性的重大变化。为了对变化的极地生态系统进行生物评价和生物保护评价，于2010年12月至2011年1月对阿蒙森海南部夏季5个生境进行了不同分类分辨率的中上层纤毛虫群落研究。5个生境（海洋区、过渡区、多冰区、冰川边缘和海冰边缘）的群落对环境变化（如温度、盐度、绿藻和营养物）的响应具有明显的空间格局。Shannon-WienerH’、Pielou’s j’和MargalefD等3个生物多样性指数的分布也呈现出明显的空间变幅，多冰区平均物种数和指数最高，过渡区属科数最高。在科级分类学分辨率上数据的存在/缺失为评价远洋纤毛虫群落的生态格局提供了足够的信息，并能准确反映生境的变化。k-优势度曲线清楚地表明，在物种水平上，冰沼区多样性最大，在属和科水平上，过渡区多样性最大。我们建议在未来的监测中应更多地考虑高分类学分辨率下的多样性。我们的研究结果为回答关于生物保护的重要问题提供了基础数据和方法，特别是在应对极地生态系统日益加剧的气候变化的不同分类分辨率下的生物多样性。
The 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 biological conservation, 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 environmental variability (e.g., temperature, salinity, chlorophylla, and nutrients). The distributions in the numbers of different taxonomic levels and of three biodiversity indices (Shannon-WienerH′, Pielou’sJ′, and MargalefD) 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 ecological patterns of pelagic ciliate communities and could accurately reflect habitat variations. Thek-dominance curves illustrated clearly that maximum diversity was presented in the polynya at the species level and in the transitional area at the genus and family level. We suggest that 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.
