Land of retreating glaciers – checklist of liverworts on Svalbard

Abstract

The checklist of liverworts of the Svalbard archipelago contains all published data on the occurrence of liverworts in the Svalbard archipelago. The list includes 105 species, five more reported species that only doubtfully occur there, and 51 species previously listed for the archipelago that are excluded from Svalbard. In addition, the locations of 67 species new to different regions of the archipelago are reported. Two species, Neoorthocaulis hyperboreus and Riccardia chamedryfolia, are listed as new to the archipelago. Two old names are typified and synonymized with taxa common on Svalbard. РезюмеЧек лист печеночников Свальбарда обобщает все опубликованные данные о распространении видов на архипелаге. Список включает 105 видов, находки еще пяти видов представляются сомнительными, a 51 вид, приводившийся ранее для архипелага исключен из состава флоры. Для 67 видов сообщается о находках, которые являются новыми для отдельных регионов архипелага. Два вида, Neoorthocaulis hyperboreus и Riccardia chamedryfolia, приводятся как новые для Свальбарда.

Contribution to the flora of Franz Josef Land Archipelago. II. Liverworts (Marchantiophyta) of Alexandra Land Island

“…Three species of the genus Marsupella were so far known from isolated localities in the Arctic. Marsupella boeckii and M. sprucei have been recorded for Svalbard in Prins Oscars Land (Konstantinova & Savchenko, 2008), and Marsupella apiculata occurs sporadically in Svalbard (Söderström et al, 2021) and recorded as well for Bolshevik Island (Potemkin & Matveyeva, 2015). The high proportion of species new to the archipelago on one of the most visited and most well-studied islands indicates that we are still far from fully recording the flora of the archipelago's liverworts.…”
