Invited review: climate change impacts in polar regions: lessons from Antarctic moss bank archives
Abstract Mosses are the dominant plants in polar and boreal regions, areas which are experiencing rapid impacts of regional warming. Long‐term monitoring programmes provide some records of the rate of recent climate change, but moss peat banks contain an unrivalled temporal record of past climate ch...

Abstract Mosses are the dominant plants in polar and boreal regions, areas which are experiencing rapid impacts of regional warming. Long‐term monitoring programmes provide some records of the rate of recent climate change, but moss peat banks contain an unrivalled temporal record of past climate change on terrestrial plant Antarctic systems. We summarise the current understanding of climatic proxies and determinants of moss growth for contrasting continental and maritime Antarctic regions, as informed by 13C and 18O signals in organic material. Rates of moss accumulation are more than three times higher in the maritime Antarctic than continental Antarctica with growing season length being a critical determinant of growth rate, and high carbon isotope discrimination values reflecting optimal hydration conditions. Correlation plots of 13C and 18O values show that species ( Chorisodontium aciphyllum / Polytrichum strictum ) and growth form (hummock / bank) are the major determinants of measured isotope ratios. The interplay between moss growth form, photosynthetic physiology, water status and isotope composition are compared with developments of secondary proxies, such as chlorophyll fluorescence.
