Abstract

This research note presents a report documenting a rare phenomenon observed in Sanionia uncinata (Hedw.) Loeske, entailing the presence of sporophytes across eight distinct locations on King George Island, Antarctica. Additionally, it briefly explores the potential correlation between regional warming air temperatures, water availability, and the emergence of these structures, suggesting their utility as indicators of climate change. Given that S. uncinata is recognized as a hygrophilic moss species typically found in well-hydrated environments, our hypothesis posits that the unprecedented development of substantial sporophyte numbers might be a consequence of rapid regional warming in the vicinity of the Antarctic Peninsula. Further investigations are essential to elucidate the potential interplay between shifting climate patterns and the observed proliferation of Sanionia uncinata sporophytes, thereby contributing to a more comprehensive understanding of their ecological responses to environmental fluctuations.

南极洲乔治王岛上出现的 Sanionia uncinata 孢子体：探索与气候变化的可能联系

本研究报告记录了在 Sanionia uncinata (Hedw.) Loeske 中观察到的一种罕见现象，即在南极洲乔治王岛的八个不同地点出现孢子体。此外，报告还简要探讨了区域气温升高、水源供应和这些结构的出现之间的潜在关联，并建议将其作为气候变化的指标。鉴于S. uncinata是公认的亲水苔藓物种，通常出现在水分充足的环境中，我们的假设认为，孢子体数量的空前增长可能是南极半岛附近地区迅速变暖的结果。进一步的研究对于阐明气候模式的变化与所观察到的Sanionia uncinata孢子体增殖之间的潜在相互作用至关重要，从而有助于更全面地了解它们对环境波动的生态反应。

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
