William C. Steere
William Campbell Steere (1907–1989) was an American botanist known as an expert on bryophytes, especially arctic and tropical American species. Early life Steere was born November 4, 1907 in Muskegon, Michigan to a family of Irish Quakers. His paternal grandfather was Joseph Beal Steere. Steere attended the University of Michigan, and earned his B.S. in botany with "high distinction". He briefly attended the University of Pennsylvania where he studied cytology under William Randolph Taylor, while also working as an instructor at Temple University. Steere was persuaded by Harley H. Bartlett to return to the University of Michigan as an instructor. He earned his M.A. in 1931 and his Ph.D. from the University in 1932. Career Steere continued to teach botany at the University of Michigan. His research was focused on bryology, and he taught courses in bryology and systematic biology with a focus on Michigan's Upper Peninsula. In 1932, he led a biological survey of the Yucatan ...

Liverwort
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly diff ...

BIOSIS
BIOSIS Previews is an English-language, bibliographic database service, with abstracts and citation indexing. It is part of ''Clarivate Analytics Web of Science'' suite. BIOSIS Previews indexes data from 1926 to the present. BIOSIS Previews is part of the ''Life Sciences'' in Web of Science. Its coverage encompasses the life sciences and biomedical sciences literature, with deep global coverage on a wide range of related subject areas. This is accomplished with access to indexed journal content from ''Biological Abstracts'', and supplemental indexed non-journal content from '' Biological Abstracts/Reports, Reviews, Meetings'' (''BA/RRM'' or ''Biological Abstracts/RRM)'' and the major publications of BIOSIS. This coverage includes literature in pre-clinical and experimental research, methods and instrumentation, animal studies, environmental and consumer issues, and other areas. The database is also provided by EBSCO Information Services through a partnership with Clarivate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Abstracts
Biological Abstracts is a database produced by Clarivate Analytics. It includes abstracts from peer-reviewed academic journal articles in the fields of biology, biochemistry, biotechnology, botany, pre-clinical and experimental medicine, pharmacology, zoology, agriculture, and veterinary medicine, and has been published since 1926. It can be accessed through a number of services, including EBSCO, Ovid and Web of Science. History The service began as a print publication in 1926, when it was formed by the union of ''Abstracts of Bacteriology'' (1917–1925), and ''Botanical Abstracts'' (1919–1926), both published in Baltimore by Williams and Wilkins. It was published in paperback subject sections, with abstracts usually written by scientists in the US, as a great many articles from that period were in other languages. At the time of founding, it was in competition with the classified indexing service of the Concilium Bibliographicum in Zurich. The first online version was publi ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest.

Great Bear Lake
Great Bear Lake ( den, Sahtú; french: Grand lac de l'Ours) is a lake in the boreal forest of Canada. It is the largest lake entirely in Canada (Lake Superior and Lake Huron are larger but straddle the Canada–US border), the fourth-largest in North America, and the eighth-largest in the world. The lake is in the Northwest Territories, on the Arctic Circle between 65 and 67 degrees of northern latitude and between 118 and 123 degrees western longitude, above sea level. The name originated from the Chipewyan language word , meaning "grizzly bear water people". The Sahtu, a Dene people, are named after the lake. Grizzly Bear Mountain on the shore of the lake also comes from Chipewyan, meaning, "bear large hill".Johnson, LThe Great Bear Lake: Its Place in History Calgary, Alberta: ''Arctic Institute of North America'' (AINA) database at the University of Calgary. pp. 236-237.

Cinchona Mission
The Cinchona Missions (1942-1945) were a series of expeditions led by the United States to find natural sources of quinine in South America during World War II. Background Bark of species from the genus ''Cinchona'' produces the alkaloid quinine, a potent anti-malarial treatment. Although originally native to South America, cinchona plantations were established in India, Ceylon, and the Dutch East Indies during the 19th century. By 1913, 95 percent of quinine production was controlled by the Dutch through large plantations on Java. With the outbreak of World War II, a supply of quinine was essential for successful military operations. In 1942, the Japanese occupation of the Dutch East Indies cut off the supply of quinine to the allies. Recognizing the need for a new source of quinine, a program was established by the United States Board of Economic Warfare under the operation of the Defense Supplies Corporation (DSC). Professor William C. Steere was brought on as assistant dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quinine
Quinine is a medication used to treat malaria and babesiosis. This includes the treatment of malaria due to ''Plasmodium falciparum'' that is resistant to chloroquine when artesunate is not available. While sometimes used for nocturnal leg cramps, quinine is not recommended for this purpose due to the risk of serious side effects. It can be taken by mouth or intravenously. Malaria resistance to quinine occurs in certain areas of the world. Quinine is also used as an ingredient in tonic water to impart a bitter taste. Common side effects include headache, ringing in the ears, vision issues, and sweating. More severe side effects include deafness, low blood platelets, and an irregular heartbeat. Use can make one more prone to sunburn. While it is unclear if use during pregnancy causes harm to the baby, treating malaria during pregnancy with quinine when appropriate is still recommended. Quinine is an alkaloid, a naturally occurring chemical compound. How it works as a medicin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
