Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botany, botanist of the 19th century. His ''Darwiniana'' (1876) was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built a ...

Aimée Antoinette Camus
Aimée Antoinette Camus (1 May 1879 – 17 April 1965) was a French botanist. She was best known for her study of orchids and oaks. Camus also has the legacy of authoring the second highest number of land plant species among female scientists, in total naming 677 species. Biography Camus was the daughter of Edmond Gustave Camus, also a botanist, and was born in L'Isle-Adam, about 50 kilometres north of Paris. Under her father's influence, she specialized in the study of orchids and the anatomy of the plant and worked for some time with other professionals such as Paul Bergon (1863-1912) and Paul Henri Lecomte (1856-1934). She was especially close to her sister, the painter Blanche-Augustine Camus (1881-1968). Collaboration with the Paris Natural History Museum From 1922, Camus voluntarily collaborated for more than 30 years as a free worker for the Paris Natural History Museum and her numerous publications are part of the Museum's collections.

Hu Hsen-Hsu
Hu Xiansu or Hu Hsen-Hsu (, 24 May 1894 – 16 July 1968), courtesy name Buzeng (), was a Chinese botanist, scholar, literary critic and educator. He was the founder of plant taxonomy in China and a pioneer of modern botany and paleobotany research in the country. One of his most notable achievements as a botanist was the identification of the living fossil ''Metasequoia glyptostroboides'' (dawn redwood) in the 1940s, which was previously thought to have been extinct for over 150 million years. This has been considered by some in the scientific community as one of the greatest botanical discoveries of the 20th century. Outside botany, Hu also made significant contributions in the field of literary critique and education. In 1922, in opposition of the New Culture Movement that promoted vernacular literature, Hu co-founded '' The Critical Review'', a major Chinese-language journal which advocated the preservation of Chinese classical literature. From 1940 to 1944, Hu served as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wan Chun Cheng
Wan Chun Cheng or Zheng Wanjun (, 24 June 1908–25 July 1987) was a Chinese botanist. Initially one of the Chinese plant collectors who followed in the wake of the Europeans after 1920, he became one of the world's leading authorities on the taxonomy of gymnosperms. Working at the National Central University in Nanjing, he was instrumental, along with H.H.Hu, in the identification in 1944 of the dawn redwood, ''Metasequoia glyptostroboides ''Metasequoia glyptostroboides'', the dawn redwood, is a fast-growing, endangered deciduous pinophyta, conifer.

Quercus
An oak is a hardwood tree or shrub in the genus ''Quercus'' of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve. Ecologically, oaks are keystone species in habitats from Mediterranean semi-desert to subtropical rainforest. They live in association with many kinds of fungi including truffles. Oaks support more than 950 species of caterpillar, many kinds of gall wasp which form distinctive galls (roundish woody lumps such as the oak apple), and a large number of pests and diseases. Oak leaves and acorns contain enough tannin to be toxic to cattle, but pigs are ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Geography of Taiwan, Taiwan: the Ryukyu Islands are divided into the Satsunan Islands (Ōsumi Islands, Ōsumi, Tokara Islands, Tokara and Amami Islands, Amami) and Okinawa Prefecture (Daitō Islands, Daitō, Miyako Islands, Miyako, Yaeyama Islands, Yaeyama, Senkaku Islands, Senkaku, Okinawa Islands, Okinawa, Sakishima Islands (further divided into the Miyako Islands, Miyako and Yaeyama Islands), and Yonaguni as the westernmost). The larger ones are mostly volcanic islands and the smaller mostly coral island, coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain ha ...

Binchōtan
''Binchō-tan'' (, ), also called white charcoal or ''binchō-zumi,'' is a type of high-quality charcoal traditionally used in Japanese cooking. Its use dates back to the Edo period when during the Genroku era, a craftsman named Bichū-ya Chōzaemon () began to produce it in Tanabe, Wakayama. The typical raw material used to make ''binchō-tan'' in Japan is oak, specifically , now the official tree of Wakayama Prefecture. Wakayama continues to be a major producer of high-quality charcoal, with the town of Minabe, Wakayama, producing more ''binchō-tan'' than any other town in Japan. ''Binchō-tan'' produced in Wakayama is referred to as ''Kishū binchō-tan'' (), Kishū being the old name of Wakayama. White charcoal is made by pyrolysing wood in a kiln at approximately for 120 hours, then raising the temperature to around . Once carbonised, the material is taken out and covered to cure in a damp mixture of earth, sand Sand is a granular material composed of finel ...

Activated Carbon
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area available for ''adsorption '' or chemical reactions. (Adsorption, not to be confused with Absorption (chemistry), absorption, is a process where atoms or molecules adhere to a surface). The pores can be thought of as a microscopic "sponge" structure. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. ''Activated'' is sometimes replaced by ''active''. Because it is so porous on a microscopic scale, one gram of activated carbon has a surface area of over , as determined by gas absorption and its porosity can run 10ML/day in terms of treated water per gram. Researchers at Cornell University synthesized an ultrahigh surface area activated ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Tree
Urban forestry is the care and management of single trees and tree populations in Urban area, urban settings for the purpose of improving the urban environment. Urban forestry involves both planning and management, including the programming of care and maintenance operations of the urban forest. Urban forestry advocates the role of trees as a critical part of the urban infrastructure. Urban foresters plant and maintain trees, support appropriate tree and forest preservation, conduct research and promote the many benefits trees provide. Urban forestry is practiced by municipal and commercial arborists, municipal and utility foresters, environmental policymakers, city planners, consultants, educators, researchers and community activists. Benefits Environmental and health impacts Heat waves cause 1,300 deaths each year in the United States alone, which is more than any other weather-related event.

Flora Of South-Central China
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...
