“…Desolation of the moss can be caused by burial under perennial snow(Yu et al 2016). Such buried under snow patch moss bank was found on Died Moss Ravine on the Galindez Island(Parnikoza et al 2016b;Yevchun et al 2021b). Figure1, demonstrates the remnants of moss banks destroyed by the expansion of the gentoo penguins that started in the summer of 2007/2008 on the Galindez Island (Parnikoza et al…”

Tall moss turf subformation, whose developed forms are called moss banks (MB), play an important role in the structure of vegetation communities in the maritime Antarctic. In the present research, we studied the spatial distribution, moss banks thickness, area, species amount, dependence between these parameters, and species composition of the 44 MB on Galindez Island, Argentine Islands, Graham Coast.To select indicators for the monitoring of communities affected by climate change and biotic disturbance we compared the key parameters of the largest moss bank on Galindez Island (Smith moss bank) with measurements received for this moss bank 46 years ago. Galindez moss banks' bryophyte ora included 13 species of mosses and three species of liverworts. There was no correlation between the species richness and the area of MB, but the species richness positively correlated with moss banks' thickness. We supposed species diversity of MB depended presumably on the age of the moss bank and microconditions than on the area. Abundance of some moss species correlated with moss bank thickness. A comparison of results obtained in this study and in 1976, revealed an increase in the amount of brownand black-coloured curtains of Polytrichum strictum, no signi cant changes in the ratio of Chorisodontium aciphyllum and a decrease in the lichen incrustation. These results show that the ratio of P. strictum's colour morphotypes, C. aciphyllum and liverworts' abundance can be used to evaluate the condition of MB in the long-term monitoring.

This paper documents the occurrence of the genus Umbilicaria in the Argentine Islands–Kyiv Peninsula region of the Graham Coast in the maritime Antarctic. The presence of seven Umbilicaria species ( U. africana, U. antarctica, U. aprina, U. decussata, U. kappenii, U. nylanderiana and U. umbilicarioides ) in the ice-free areas of the Argentine Islands–Kyiv Peninsula region were confirmed. The species of U. africana and U. aprina are documented from the studied region for the first time. This study moves the southern distribution limit of U. africana about 300 km to the south: to the Argentine Islands–Kyiv Peninsula region. The distribution maps of Umbilicaria species for the studied region and maritime Antarctica are prepared.

Tall moss turf subformation, whose developed forms are called moss banks (MB), play an important role in the structure of vegetation communities in the maritime Antarctic. In the present research, we studied the spatial distribution, moss banks thickness, area, species amount, dependence between these parameters, and species composition of the 44 MB on Galindez Island, Argentine Islands, Graham Coast. To select indicators for the monitoring of communities affected by climate change and biotic disturbance we compared the key parameters of the largest moss bank on Galindez Island (Smith moss bank) with measurements received for this moss bank 46 years ago. Galindez moss banks’ bryophyte flora included 13 species of mosses and three species of liverworts. There was no correlation between the species richness and the area of MB, but the species richness positively correlated with moss banks’ thickness. We supposed species diversity of MB depended presumably on the age of the moss bank and micro-conditions than on the area. Abundance of some moss species correlated with moss bank thickness. A comparison of results obtained in this study and in 1976, revealed an increase in the amount of brown- and black-coloured curtains of Polytrichum strictum, no significant changes in the ratio of Chorisodontium aciphyllum and a decrease in the lichen incrustation. These results show that the ratio of P. strictum’s colour morphotypes, C. aciphyllum and liverworts’ abundance can be used to evaluate the condition of MB in the long-term monitoring.
