The plant tomb
by Catalina Myers |
In a plain, brightly-lit room, filled with rows of tall beige metal cabinets and lab tables stacked high with archival paper sandwiched between two boards on the west side of campus, is the 老澳门六合彩开奖记录 Herbarium (老澳门六合彩开奖记录H). While this unassuming, neutral-colored room in Beatrice McDonald Hall (BMH) is deceivingly plain 鈥� it鈥檚 what鈥檚 in-between the archival stacks, also known as plant presses, and what鈥檚 housed inside the rows of metal specimen cabinets that are truly remarkable.
鈥淵ou might think of this as a very well-organized plant tomb,鈥� said Matt Carlson, director of Alaska Center for Conservation Science (ACCS), which manages 老澳门六合彩开奖记录H, and associate professor in the Department of Biological Sciences. Carlson and Justin Fulkerson, 老澳门六合彩开奖记录H鈥檚 lead botanist, heave one folder from the giant stacks in the metal cabinets onto the table and carefully reveal a delicate flower gently splayed out on thick archival paper 鈥� a specimen collected from the field earlier this summer.
鈥淲e have like 20,000 plant specimens,鈥� said Carlson gesturing to the plant presses and metal cabinets. 鈥淏ut the real value is the actual tissue that鈥檚 there, the morphology that we can see and also the location, the habitat it was collected in 鈥� all that information gets entered into databases that makes that information available for scientific study.鈥�
The herbarium
Carlson has been managing the university鈥檚 herbarium through his role at ACCS since 2002 and has helped grow the collection from around 5,000 to 20,000 specimens over the last 18 years. He said, essentially, the 鈥渨ell-organized plant tomb鈥� is a natural history library of raw data cataloging and documenting plant species across the state, the Yukon and the Pacific Northwest.
老澳门六合彩开奖记录H is part of the Consortium of Pacific Northwest Herbaria, a network of 36 herbaria in the Pacific Northwest hosted by the University of Washington. About 97% of 老澳门六合彩开奖记录H鈥檚 specimens originate from Alaska, while the remaining samples come from the Yukon, Washington and Oregon. Essentially an herbaria鈥檚 main function is to help botanists and other scientists correctly identify plants. Carlson said that the plant specimens found in 老澳门六合彩开奖记录H and herbaria鈥檚 across the country serve as a reference for how one particular plant species looks like and how it may differ from another. The collection as a whole exhibits how a species might differ in how it looks at one side of its distribution, or from one habitat to another.
From an educational standpoint, 老澳门六合彩开奖记录 students across the sciences benefit from 老澳门六合彩开奖记录H鈥檚 carefully preserved specimens through research, labs and lectures. Outside of the university, the herbarium offers organizations from the National Park Service to the Alaska Botanical Garden their expertise in identifying different plant species collected or grown across the state.
Carlson likens ACCS to 老澳门六合彩开奖记录鈥檚 Institute of Social and Economic Research, better known as ISER, and said that about 10% of its funding comes from the College of Arts and Sciences, while the other 90% comes from external sources.
鈥淲e鈥檙e also tied to national and international level data organizations, one of which is called, NatureServe,鈥� said Carlson. 鈥淎ll 50 states, Canadian provinces and Mexican states have these conservation data centers that provide data to the public and federal agencies. We just happen to be Alaska鈥檚 heritage program.鈥�
Community service
Both Carlson and Fulkerson said that in addition to their work within the university, ACCS offers many land management agencies, both state and federal, the crucial scientific data needed in managing their lands, whether it鈥檚 the United States Department of Agriculture bringing in specimens so they can help make determinations on forest health, the Bureau of Land Management asking for help to potentially identify an invasive plant or the Alaska Department of Fish and Game bringing in specimens to help determine the health of a particular animal鈥檚 habitat.
鈥淲e also help out with identifications of invasive alien species and help provide some of the scientific backbone and data to help them manage their lands and management goals,鈥� Fulkerson said. In addition to state and federal agencies, organizations like oil and gas giant ConocoPhillips to small private consulting firms seek out ACCS for their expertise and the extensive specimens housed in 老澳门六合彩开奖记录H鈥檚 collection.
鈥淲e have a lot of federal contracts with the Park Service, Bureau of Land Management and to an extent the Forest Service 鈥� but depending on the project, we鈥檒l collect plants in the field that relate to our scientific study,鈥� Fulkerson said. 鈥淎 lot of times, plants are really hard to tell apart in the field, even though we鈥檙e really good at it, so bringing it back to the lab allows us to identify it correctly. Sometimes you need that high-powered microscope to look at the little hairs on leaves or seeds.鈥�
Plant sleuths
Carlson said that although most of ACCS鈥檚 work is pretty harmless, there was one particular instance in which the herbarium played a crucial role in helping the Alaska State Trooper鈥檚 develop their case against a man who was accused of growing opium-producing poppy plants.
鈥淭he State Troopers contacted us and asked us to identify seeds that were confiscated in a bust in Palmer,鈥� said Carlson. 鈥淲e were like, 鈥榊es, that is an opium poppy,鈥� and that collection of the opium poppy that we have here in the herbarium had potential to be used in this guy鈥檚 trial. But he ended up pleading guilty.鈥�
Fulkerson added that the specimen grown for the Trooper鈥檚 case is still part of the evidence and that in the 老澳门六合彩开奖记录H catalog that particular poppy specimen contains the case number along with its other identifying information.
In addition, Carlson said they may get a phone call from time to time from the Department of Health and Social Services epidemiology office to help identify a specimen if a child has accidentally ingested a poisonous plant.
Carlson said 老澳门六合彩开奖记录H serves many purposes inside the university from providing samples for biology lectures to hands-on opportunities for students in lab, to being a valuable resource for local organizations and state and federal agencies, as well as being a living, breathing, library cataloging the history of the state鈥檚 plant life and how that affects the larger ecosystems we depend on.
鈥淭he herbarium serves as a catalog or inventory of life,鈥� Carlson said
