Margaret Bryan Davis
Dr. Margaret Bryan Davis (''née'' Margaret Bryan; born October 23, 1931) is an American palynologist and paleoecologist, who used pollen data to study the vegetation history of the past 21,000 years (i.e. since the last ice age). She showed conclusively that temperate- and boreal-forest species migrated at different rates and in different directions while forming a changing mosaic of communities. Early in her career, she challenged the standard methods and prevailing interpretations of the data and fostered rigorous analysis in palynology. As a leading figure in ecology and paleoecology, she served as president of the Ecological Society of America and the American Quaternary Association and as chair of the Department of Ecology, Evolution and Behavior at the University of Minnesota. In 1982 she was elected to the National Academy of Sciences and, in 1993, received the Eminent Ecologist Award from the Ecological Society of America. Early life and education Davis was born on October ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palynologist
Palynology is the "study of dust" (from grc-gre, παλύνω, palynō, "strew, sprinkle" and ''-logy'') or of "particles that are strewn". A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. The condition and identification of those particles, organic and inorganic, give the palynologist clues to the life, environment, and energetic conditions that produced them. The term is commonly used to refer to a subset of the discipline, which is defined as "the study of microscopic objects of macromolecular organic composition (i.e., compounds of carbon, hydrogen, nitrogen and oxygen), not capable of dissolution in hydrochloric or hydrofluoric acids". It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sediment ...

Sylvania Wilderness
Sylvania Wilderness is an protected area located a few miles west of Watersmeet Township, Michigan. Sylvania is located entirely within the bounds of the Ottawa National Forest, and is currently being managed as a wilderness area as part of the National Wilderness Preservation System by the U.S. Forest Service. Within its borders lie 34 lakes set against a backdrop of old-growth forests. It represents one of only a handful of such areas left in the Midwest. History Little is known of the area prior to the late 1800s, other than the area was frequently used by clans of Ojibwa Native Americans, as evidenced by the few scattered artifacts that have been found there. In 1895, a Wisconsin lumberman by the name of A.D. Johnston purchased of land at the south end of Clark Lake with the intent to cut the large pines located there. Upon seeing the land for himself, he was so taken by the rugged beauty of it that he changed his mind and decided to preserve it. He soon invited fr ...

People From Boston
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Women Earth Scientists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Thro ...

The Ann Arbor News
''The Ann Arbor News'' is a newspaper serving Washtenaw and Livingston counties in Michigan. Published daily online through MLive.com, the paper also publishes print editions on Thursdays and Sundays. History Original publication Published in Ann Arbor under various names from 1835 to 2009, ''The News'' was part of Booth Newspapers, owned by Advance Publications Inc. ''The News'' was published in the afternoons Monday through Friday and in the mornings on weekends and holidays. It published special sections throughout the year. The newspaper ended its 174-year print run on July 23, 2009. The publisher blamed the loss of classified advertising revenue (which moved to Craigslist), and noted "the seven-day-a-week print model just is not sustainable here. We have very low home ownership. The population is transient and young. Those demographics have worked against us." Web site ''The Ann Arbor News'' was replaced by a Web site, AnnArbor.com, which carried daily news stories and w ...

British Ecological Society
The British Ecological Society is a learned society in the field of ecology that was founded in 1913. It is the oldest ecological society in the world. The Society's original objective was "to promote and foster the study of Ecology in its widest sense" and this remains the central theme guiding its activities today. The Society had, circa 2013 around 4,000 members of which 14% are students. Of its members, 42% are outside the United Kingdom, in a total of 92 countries. The head office is located in London. History The Society evolved out of the British Vegetation Committee, which was founded in 1904 to promote the survey and study of vegetation in the British Isles. This initiative was in turn the outcome of what many historians perceive to have been the emergence of modern ecology in the 1890s. The British Ecological Society's inaugural meeting was held at University College London on 12 April 1913 and was attended by 47 members. Sir Arthur Tansley became the first Presid ...

National Women's History Month
Women's History Month is an annual declared month that highlights the contributions of women to events in history and contemporary society. It is celebrated during March in the United States, the United Kingdom, and Australia, corresponding with International Women's Day on March 8, and during October in Canada, corresponding with the celebration of Persons Day on October 18. The commemoration began in 1978 as "Women's History day" in Sonoma County, California, and was championed by Gerda Lerner and the National Women's History Alliance to be recognized as a national week (1980) and then month (1987) in the United States, spreading internationally after that. History In the United States Women's History Week In the United States, Women's History Month traces its beginnings back to the first International Women's Day in 1911. In 1978, the school district of Sonoma, California participated in Women's History Week, an event designed around the week of March 8 (International ...

Eminent Ecologist Award
The Eminent Ecologist Award is prize awarded annually to a senior ecologist in recognition of an outstanding contribution to the science of ecology. The prize is awarded by the Ecological Society of America. According to the statutes, the recipient may be from any country in the world.
