| Zusammenfassung: | The lichens of Tetlin National Wildlife Refuge (NWR) and adjacent lands were collected and recorded at sites selected to represent the range of environmental variation. One hundred ninety-two taxa of lichens are reported from an area where few previous collections have been recorded. Six species are new to Alaska-Aspicilia arctica, Caloplaca arenaria, C. xanthostigmoidea, Endocarpon pusillum, Ramalina intermedia and Rhizocarpon cinereovirens. To provide a comparative phytogeographic framework for Tetlin NWR, we analyzed data from published reports and categorized lichen distribution patterns from a circumpolar perspective. Wide-ranging arctic-alpine and boreal species dominate the lichen flora, while amphi-Beringian species form a minor element. |
