Adrian Hardy Haworth
Adrian Hardy Haworth (19 April 1767, in Kingston upon Hull, Hull – 24 August 1833, in Chelsea, London, Chelsea) was an England, English entomologist, botanist and carcinologist. Family The younger son of Benjamin Haworth, of Haworth Hall and Anne Booth baronets, Booth, he was educated at Hull Grammar School and by tutors who steered him towards a career in the law. After inheriting the family estate, he devoted all his time to natural history. He married three times, firstly in 1792 to Elizabeth Sidney Cumbrey (died 1803), secondly in 1805 to Amy Baines (died 1813), and lastly in 1819 to Elizabeth Maria Coombs, who survived him. By his first wife, he left children from whom descend the Haworth-Booths. Career In 1792 he settled in Little Chelsea, London, where he met William Jones (naturalist), William Jones (1750–1818) who was to have a great influence on him. He became a Fellow of the Linnean Society of London in 1798. His research work was aided by his use of the library ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Grasslands, Savannas, And Shrublands
Temperate grasslands, savannas, and shrublands are terrestrial biomes defined by the World Wide Fund for Nature. The predominant vegetation in these biomes consists of grass and/or shrubs. The climate is temperate and ranges from Semi-arid climate, semi-arid to semi-humid. The habitat type differs from tropical grasslands in the annual temperature regime and the types of species found here. The habitat type is known as prairie in North America, pampas in South America, veld in Southern Africa and steppe in Asia. Generally speaking, these regions are devoid of trees, except for riparian or gallery forests associated with streams and rivers. Steppes/shortgrass prairies are short grasslands that occur in semi-arid climates. Tallgrass prairies are tall grasslands in higher rainfall areas. Heath (habitat), Heaths and pastures are, respectively, low shrublands and grasslands where forest growth is hindered by human activity but not the climate. Tall grasslands, including the tallgras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opuntia
''Opuntia'', commonly called the prickly pear cactus, is a genus of flowering plants in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. Cacti are native to the Americas, and are well adapted to arid climates; however, they are still vulnerable to alterations in precipitation and temperature driven by climate change. The plant has been introduced to parts of Australia, southern Europe, the Middle East, and northern Africa. ''Prickly pear'' alone is more commonly used to refer exclusively to the fruit, but may also be used for the plant itself; in addition, other names given to the plant and its specific parts include ''tuna'' (fruit), ''sabra'', ''sabbar'', '' nopal'' (pads, plural ''nopales'') from the Nahuatl word , nostle (fruit) from the Nahuatl word , and paddle cactus. The genus is named for the Ancient Greek city of Opus. The fruit and leaves are edible. The most common culinary species is the "Barbary fig" ('' Opuntia ficus-indica ...

Lewis And Clark Expedition
The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark, along with 30 others, set out from Camp Dubois (Camp Wood), Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, ending six months later on September 23 of that year. President Thomas Jefferson commissioned the expedition, shortly after the Louisiana Purchase of 1803, to explore and detail as much of ...

Wildfire
A wildfire, forest fire, or a bushfire is an unplanned and uncontrolled fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire (Bushfires in Australia, in Australia), desert fire, grass fire, hill fire, Peat#Peat fires, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems Fire ecology, depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake. Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pronghorn
The pronghorn (, ) (''Antilocapra americana'') is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope, and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. During the Pleistocene epoch, about 11 other antilocaprid species existed in North America, many with long or spectacularly twisted horns.Smithsonian Institution. North American MammalsPronghorn ''Antilocapra americana'' Three other genera ('' Capromeryx'', '' Stockoceros'' and '' Tetrameryx'') existed when humans entered North America but are now extinct. The pronghorn's closest living relatives are the giraffe and okapi. See Fig. S10 in Supplementary Information. The antilocaprids are part of ...

Black-tailed Prairie Dog
The black-tailed prairie dog (''Cynomys ludovicianus'') is a rodent of the family Sciuridae (the squirrels) found in the Great Plains of North America from about the United States–Canada border to the United States–Mexico border. Unlike some other prairie dogs, these animals do not truly hibernate. The black-tailed prairie dog can be seen above ground in midwinter. A black-tailed prairie dog town in Texas was reported to cover and included 400,000,000 individuals. Prior to habitat destruction, the species may have been the most abundant prairie dog in central North America. It was one of two prairie dogs described by the Lewis and Clark Expedition in the journals and diaries of their expedition. Description Black-tailed prairie dogs are generally tan in color, with lighter-colored bellies. They may have color variation in their pelt, such as dark fur on their back in black and brown tones. Their tails have black tips, from which their name is derived. Adults can weigh from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicinal Plant
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including Plant defense against herbivory, defense and protection against insects, fungi, Plant disease resistance, diseases, against parasites and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, . The Ebers Papyrus from ancient Egypt, , describes over 850 plant medicines. The Greek physician Pedanius Dioscorides, Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in , ; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of use ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...
