The Arctic has been, and is, an area of focus for the botanical and fungal (lichenized fungi included) collections at the Natural History Museum of Oslo. These collections house more than 233,000 unique Arctic specimens, the oldest dating back more than two centuries. The vascular plants account for 63 percent, lichens 30 percent, and fungi 7 percent. The Arctic collections have a circumpolar representation with emphasis on mainland Norway (48 percent) and Svalbard (13 percent), followed by Arctic America (10 percent), Greenland (9 percent), and Arctic Russia (8 percent). The Oslo herbarium and fungarium house collections from important polar expeditions like Fram-2, Gjøa, and Maud, but also of many expeditions where collecting biological specimens was the main purpose. The number of new collections was highest in the decades 1930 to 1939 and 2000 to 2009 with each around 35,000 new specimens. In the 1990s, a DNA Bank was established for DNA extracts and tissue samples, and it houses today 22,879 Arctic accessions of fungi, lichens, and plants. In times of climatic change and a tense geopolitical situation, the herbarium and fungarium at NHM-Oslo represent an invaluable source for biological information about the Arctic. We welcome the use of our collections for research-, nature management-, and teaching purposes. |
