摘要

本研究提供了南设得兰群岛(SSI)和南极半岛东北部(EAP)威德尔海岩石栖息地大型藻类群落的新物种记录。调查于2013/2014年至2017/2018年夏季在大象岛、欺骗岛、半月岛和织女星岛进行。本研究的数据和南极半岛西部文献中的数据相结合,提供了一份更新的清单,深入了解了宏观生态学和温盐环流模式的潜在变化。从我们的采样中总共鉴定了48个大型藻类分类群,其中8个代表威德尔海EAP部门的NR,5个代表SSI的NR。SSI、WAP和EAP的组合之间存在统计差异。NRs,包括机会物种和这里报道的物种生物地理分布的新信息,可以深入了解生态区域的连通性和环境变化。这项研究更新了目前正经历气候变化影响的地区的大型藻类多样性记录。需要为保护目的进行未来和持续的监测,以检测与南极水域温盐异常有关的非本土物种、新的传播途径和模式。

New records and updated distributional patterns of macroalgae from the South Shetland Islands and northern Weddell Sea, Antarctica
This study provides new species records (NRs) of macroalgal assemblages present in rocky habitats from the South Shetland Islands (SSI) and north-eastern Antarctic Peninsula (EAP), Weddell Sea. Surveys were conducted during the summers of 2013/2014 to 2017/2018 at Elephant, Deception, Half Moon and Vega islands. Data from the present study and those available in the literature from the western Antarctic Peninsula (WAP) were combined to provide an updated checklist, giving insights into macroecology and potential changes in thermohaline circulation patterns. A total of 48 macroalgal taxa were identified from our sampling, with eight representing NRs to the EAP sector of the Weddell Sea and five representing NRs to the SSI. Statistical differences among the assemblages from the SSI, WAP and EAP were identified. NRs, including opportunistic species and new information about the biogeographical distributions of species reported here, give insights into ecoregional connectivity and environmental changes. This study updates macroalgal diversity records in regions that are currently experiencing the impacts of climate change. Future and ongoing monitoring for conservation purposes is required to detect non-native species, new dispersal pathways and patterns related to thermohaline anomalies in Antarctic waters.

期刊介绍: Antarctic Science provides a truly international forum for the broad spread of studies that increasingly characterise scientific research in the Antarctic. Whilst emphasising interdisciplinary work, the journal publishes papers from environmental management to biodiversity, from volcanoes to icebergs, and from oceanography to the upper atmosphere. No other journal covers such a wide range of Antarctic scientific studies. The journal attracts papers from all countries currently undertaking Antarctic research. It publishes both review and data papers with no limits on length, two-page short notes on technical developments and recent discoveries, and book reviews. These, together with an editorial discussing broader aspects of science, provide a rich and varied mixture of items to interest researchers in all areas of science. There are no page charges, or charges for colour, to authors publishing in the Journal. One issue each year is normally devoted to a specific theme or papers from a major meeting.
