UAM Herbarium (ALA), Cryptogam Collection (Arctos)

The Herbarium (ALA) at the University of Alaska Museum is the major regional herbarium in Alaska and part of a network of similar collections with an interest in the origin and evolution of the circumpolar flora. ALA contains more than 260,000 specimens of vascular and non-vascular plants. Data for the Vascular Plant and Cryptogam collections are managed separately in Arctos. Most lichen collections in the ALA date from the early post WWII period, after the Alcan (now Alaska Highway) was completed, including specimens from John Thomson’s first of two Alaska expeditions in 1958 on the Arctic Slope as well as his 1967 expedition along the Alaska Highway. The contributions of three other people, H. Persson and W. C. Steere (bryophytes) and H. Krog (lichens), further strengthened the foundation for ALA’s cryptogamic collections. Barbara Murray’s collecting started in the 1970s just after the discovery of oil at Prudhoe Bay on the arctic coast of Alaska. Use of helicopters became frequent and as a result Murray has collected large number of specimens at over 250 Alaskan localities. The ALA cryptogamic collection has recently been supported by two NSF grants (NSF- 1023407: Toward Documenting Biodiversity Change in Arctic Lichens: Databasing the Principal Collections, Establishing a Baseline, and Developing a Virtual Flora (with University of Wisconsin) and NSF NSF-1115056: TCN Collaborative Research: North American Lichens and Bryophytes: Sensitive Indicators of Environmental Quality and Change) to help with digitization of specimen data and taking care of large backlogs of specimens. The majority of the cryptogam collections are from Alaska, while numerous collections are also from Russia, Fennoscandia, Canada and the lower 48 United States.

阿拉斯加大学博物馆的阿拉斯加植物标本馆（ALA）是阿拉斯加地区核心区域性植物标本馆，同时隶属于一个聚焦环北极植物区系起源与演化的同类馆藏网络。ALA馆藏逾26万份维管植物与非维管植物标本。维管植物与隐花植物（Cryptogam）馆藏的数据分别在Arctos系统中独立管理。ALA的多数地衣馆藏形成于二战后早期，即阿拉斯加公路（原称Alcan公路，现为阿拉斯加高速公路）建成之后，其中涵盖约翰·汤姆森1958年首次阿拉斯加科考（他共开展两次阿拉斯加科考）于北极坡采集的标本，以及其1967年沿阿拉斯加公路科考的采集物。另有三位学者的馆藏贡献进一步夯实了ALA隐花植物馆藏的基础：研究苔藓植物（bryophytes）的H·珀森（H. Persson）、W·C·斯蒂尔（W. C. Steere），以及研究地衣的H·克羅格（H. Krog）。芭芭拉·默里（Barbara Murray）的标本采集工作始于20世纪70年代，彼时阿拉斯加北极海岸普拉德霍湾刚发现石油。当时直升机的使用愈发频繁，默里借此在阿拉斯加超250个采集点获取了大量标本。近年来，ALA的隐花植物馆藏获得两项美国国家科学基金会（NSF）资助项目的支持：其一为NSF-1023407项目《北极地衣生物多样性变化记录：核心馆藏数字化、基线建立与虚拟植物区系开发（与威斯康星大学合作）》，其二为NSF-1115056项目《TCN合作研究：北美地衣与苔藓植物——环境质量与变化的敏感指示物》，以助力标本数据的数字化工作，并处理积压的大量馆藏标本。隐花植物馆藏的绝大多数标本源自阿拉斯加，同时也有大量馆藏来自俄罗斯、芬诺斯坎迪亚（Fennoscandia）、加拿大以及美国本土48州。
