Mosses (Bryophyta) of the north-western region of Marambio (Seymour) Island, Antarctica

Abstract

Marambio (Seymour) Island is located in the James Ross Archipelago east of the Antarctic Peninsula. Although several research groups havecarried out studies on the biodiversity on the island for decades, surveys of bryophytes have not been developed. That is why there arecurrently only six species of mosses recorded in the northern part of the island. During the 2021–2022 summer Antarctic field trip, 15mosses species were surveyed in Marambio Island. Of the total number of collected species, nine are reported for the first time forMarambio Island. For the remaining four species, their distributions are now expanded to Marambio Island.
