George Suckley
George Suckley (1830–1869) was an American physician and naturalist notable as an explorer of the Washington and Oregon territories in the 1850s, and describer of several new fish species. Life He was born in New York City, studied at the College of Physicians and Surgeons (today Columbia University), received an M.D. in 1851, and subsequently served as surgeon at New York Hospital. In April 1853 Suckley was appointed assistant surgeon and naturalist to the Pacific Railroad Survey led by Isaac Stevens. Initially commissioned as a surgeon with the U.S. Army, Suckley resigned in 1856 to pursue natural history full-time resulting in the publication of several works on the natural history of the Pacific Northwest. Upon the outbreak of the American Civil War, Suckley rejoined the Army and worked as a surgeon throughout the war. He died in New York City a few years after the war. Two fish species, ''Squalus suckleyi'' Girard 1855, and '' Catostomus sucklii'' Girard 1856, and the bum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multnomah (tribe)
The Multnomah are a tribe of Chinookan people who live in the area of Portland, Oregon, in the United States. Multnomah villages were located throughout the Portland basin and on both sides of the Columbia River. The Multnomah speak a dialect of the Upper Chinookan language in the Oregon Penutian family. History The Multnomah people are a band of the Chinookan peoples who originally resided on and near Sauvie Island in Oregon. The Multnomah and the related Clackamas tribes lived in a series of villages along the river near the mouth of the Willamette River on the Columbia River (the Willamette was also called the "Multnomah" in the early 19th century). According to archaeologists, the villages in the area were home to approximately 3,400 people year-round, and as many as 8,000 during fishing and wappato-harvesting seasons (wappato is a marsh-grown plant like a potato or onion and a staple food). In 1830, a disease generally thought to have been malaria devastated the Multnoma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Robert J
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Yellowstone Cutthroat Trout
The Yellowstone cutthroat trout (''Oncorhynchus clarkii bouvieri'') is a subspecies of the cutthroat trout (''Oncorhynchus clarkii''). It is a freshwater fish in the salmon family (family Salmonidae). Native only to a few U.S. states, their original range was upstream of Shoshone Falls on the Snake River and tributaries in Wyoming, also across the Continental Divide in Yellowstone Lake and in the Yellowstone River as well as its tributaries downstream to the Tongue River in Montana. The species is also found in Idaho, Utah and Nevada. Population threats Their range has been reduced by overfishing and habitat destruction due to mining, grazing, and logging, and population densities have been reduced by competition with non-native brook, brown, and rainbow trout since these were introduced in the late 19th and early 20th centuries. However, the most serious current threats to the subspecies are interbreeding with introduced rainbow trout (resulting in cutbows) in the Greater Yel ...

Barton Warren Evermann
Barton Warren Evermann (October 24, 1853 – September 27, 1932) was an American ichthyologist. Early life and education Evermann was born in Monroe County, Iowa in 1853. His family moved to Indiana while he was still a child and it was there that he grew up, completed his education, and married. Evermann graduated from Indiana University in 1886. Career For 10 years, he served as teacher and superintendent of schools in Indiana and California. While teaching in Carroll County, Indiana Evermann met fellow teacher Meadie Hawkins. They married on October 24, 1875 and had a son, Toxaway Bronte (born 1879) and a daughter, Edith (born). He was professor of biology at the Indiana State University in Terre Haute from 1886 to 1891. He lectured at Stanford University in 1893–1894, at Cornell University in 1900–1903, and at Yale University in 1903–1906.

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meriwether Lewis
Meriwether Lewis (August 18, 1774 – October 11, 1809) was an American explorer, soldier, politician, and public administrator, best known for his role as the leader of the Lewis and Clark Expedition, also known as the Corps of Discovery, with William Clark. Their mission was to explore the territory of the Louisiana Purchase, establish trade with, and sovereignty over the natives near the Missouri River, and claim the Pacific Northwest and Oregon Country for the United States before European nations. They also collected scientific data, and information on indigenous nations. President Thomas Jefferson appointed him Governor of Upper Louisiana in 1806. He died of gunshot wounds in what was either a murder or suicide, in 1809. Life and work Meriwether Lewis was born August 18, 1774, on Locust Hill Plantation in Albemarle County, Colony of Virginia, in the present-day community of Ivy. He was the son of William Lewis, of Welsh ancestry, and Lucy Meriwether, of English ancestr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Falls (Missouri River)
The Great Falls of the Missouri River are a series of waterfalls on the upper Missouri River in north-central Montana in the United States. From upstream to downstream, the five falls along a segment of the riverCutright, Paul Russell, and Johnsgard, Paul A. ''Lewis and Clark: Pioneering Naturalists.'' 2d ed. Lincoln, Neb.: University of Nebraska Press, 2003. are: *Black Eagle Falls () *Colter Falls () * Rainbow Falls () *Crooked Falls, also known as Horseshoe Falls () * Big Falls, also known as the Great Falls, () The Missouri River drops a total of from the first of the falls to the last, which includes a combined of vertical plunges and of riverbed descent. The Great Falls have been described as "spectacular", one of the "scenic wonders of America", and "a major geographic discovery". When the Lewis and Clark Expedition became the first white men to see the falls in 1805, Meriwether Lewis said they were the grandest sight he had beheld thus far in the journey.Pritchett, M ...

Fly Fishing
Fly fishing is an angling method that uses a light-weight lure—called an artificial fly—to catch fish. The fly is cast using a fly rod, reel, and specialized weighted line. The light weight requires casting techniques significantly different from other forms of casting. The flies may resemble natural invertebrates, bait-fish, or other food organisms. Fly fishing can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species, notably bass. In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout and salmon versus coarse fishing for other species. Techniques for fly fishing differ with habitat (lakes and ponds, small streams, large rivers, bays and estuaries, and open ocean.) Author Izaak Walton called fly fishing "The Contemplative Man's Recreation". Overview In fly fishing, fish are caught by using artificial flies that ar ...

Isaac Stevens
Isaac Ingalls Stevens (March 25, 1818 – September 1, 1862) was an American military officer and politician who served as governor of the Territory of Washington from 1853 to 1857, and later as its delegate to the United States House of Representatives. During the American Civil War, he held several Union commands. He was killed at the Battle of Chantilly, while at the head of his men and carrying the fallen colors of one of his regiments against Confederate positions. According to one account, at the hour of his death Stevens was being considered by President Abraham Lincoln for appointment to command the Army of Virginia. He was posthumously advanced to the rank of Major General. Several schools, towns, counties, and lakes are named in his honor. Descended from early American settlers in New England, Stevens – a man who stood just tall – overcame a troubled childhood and personal setbacks to graduate at the top of his class at West Point before embarking on a successful mi ...
