Oregon Silverspot
''Speyeria zerene hippolyta'', the Oregon silverspot, is a threatened butterfly that is found in the U.S. states of California and Oregon. It is a subspecies of ''Speyeria zerene''. Taxonomy ''Speyeria zerene hippolyta'' was described by American lepidopterist William Henry Edwards in 1879 as a subspecies of ''Speyeria zerene'', Zerene Fritillary, which was described by French lepidopterist Jean Baptiste Boisduval in 1852. Phylogeny ''Speyeria zerene hippolyta'' is in a clade of three closely related subspecies. In suitable habitat along the U.S. Pacific coast, it is the northernmost one found. Further south, Myrtle's silverspot (''Speyeria zerene myrtleae'') had a range along the coast from San Mateo County to Sonoma County, California, and Behren's silverspot ('' Speyeria zerene behrensii'') had a range along the northern California coast. McHugh et al. (2013) conducted a genetic analysis of ''S. z. hippolyta'' and other ''S. zerene'' subspecies using mitochondrial ...

William Henry Edwards
William Henry Edwards (March 15, 1822 – April 2, 1909) was an American businessman and entomologist. He was an industrial pioneer in the coalfields of West Virginia, opening some of the earliest mines in the southern part of the state. He was also a prominent naturalist specializing in the study of butterflies. He wrote ''The Butterflies of North America'', a three-volume treatise that is highly regarded for its scholarship and the quality of its illustrations. Biography Edwards was born in Hunter, New York, a village that had been founded by his family just five years earlier and originally called Edwardsville. The son of William W. Edwards and Helen Ann (Mann) Edwards, he came from a prominent and successful American family. His father was a businessman involved in banking, insurance and European imports. His grandfather was Colonel William Edwards, founder of the family tannery business and inventor of several devices used in the manufacture of leather goods. His great-great- ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Fish And Wildlife Service
The United States Fish and Wildlife Service (USFWS or FWS) is an agency within the United States Department of the Interior dedicated to the management of fish, wildlife, and natural habitats. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people." Among the responsibilities of the USFWS are enforcing federal wildlife laws; protecting endangered species; managing migratory birds; restoring nationally significant fisheries; conserving and restoring wildlife habitats, such as wetlands; helping foreign governments in international conservation efforts; and distributing money to fish and wildlife agencies of U.S. states through the Wildlife Sport Fish and Restoration Program. The vast majority of fish and wildlife habitats are on U.S. state, state or private land not controlled by the United States government. Therefore, the USFWS works closely with private g ...

Viola Adunca
''Viola adunca'' is a species of violet known by the common names hookedspur violet, early blue violet, sand violet, and western dog violet. It is native to meadows and forests of western North America, Canada, and the northern contiguous United States. Description This is a hairy, compact plant growing from a small rhizome system. The leaves are spade- or heart-shaped, sometimes with broadly wavy margins. They are generally 0.5 to 4 centimeters long. The single-flowered inflorescence grows at the end of a very thin peduncle reaching about high. The nodding flower is a violet about long, with five purple petals. The lower three petals have white bases and purple veining. The two side petals are white-bearded near the throat. The upper two petals may have hooked spurs at their tips. It is a perennial blooming in late spring. There are several varieties of ''V. adunca''; a white-petaled form has been noted in Yosemite National Park. It has also been observed in Southern Ontar ...

Ecological Succession
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire) or more or less. Bacteria allows for the cycling of nutrients such as carbon, nitrogen and sulphur. The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment. Succession is a process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clatsop Plains
The Clatsop Plains are an area of wetlands and sand dunes between the Northern Oregon Coast Range and Pacific Ocean in northwestern Oregon in the United States. They stretch from near the mouth of the Columbia River south to the vicinity of Tillamook Head near Seaside. The plains are drained by several coastal rivers include the Skipanon River and the Necanicum River, which flow parallel to the coast and empty into the Columbia at Youngs Bay near Astoria and into the Pacific Ocean near Seaside respectively. At the time, the Lewis and Clark Expedition recorded a different river draining the plains which entered the Pacific near the current day Camp Rilea Armed Forces Training Center. Research, 200 years later in 2005, seems to have confirmed this by locating an old river channel. The plains are named for the Clatsop tribe of Native Americans who lived in the area at the time of the arrival of Europeans and European Americans by ship at the end of the 18th century and by land ...

Lake Earl
Lake Earl is a lagoon on the extreme northern California coast, just south of the Oregon border. A navigable body of water, it lies partly within Tolowa Dunes State Park and partly within Lake Earl Wildlife Area in Del Norte County, California and the third-most important seabird area on the West Coast after the Farallons and the Channel Islands.McHugh, PaulLake Earl is pearl of northernmost coast 19 July 2007, San Francisco Chronicle, accessdate 3 January 2013 Lake Earl has two principal lobes separated by "the Narrows." The smaller lobe, which is also closer to the ocean and the sand bar breach site, is called Lake Tolowa or Lake Talawa by the California Department of Fish and Game. The larger lobe of the lagoon is Lake Earl. Lake Earl is mostly freshwater while Lake Tolowa has a higher salt content. As opposed to an estuary, which is typically open to the ocean and fresh water constantly, a lagoon seals up seasonally and fills with a predominance of fresh water. The lagoo ...

Cascade Head
Cascade Head is a headland and UNESCO biosphere reserve and United States Forest Service Experimental Forest. It is situated southwest of Portland, Oregon on the Oregon Coast between Lincoln City and Neskowin. Cascade Head Preserve is a Nature Conservancy Selected Site. The Nature Conservancy In the early 1960s, volunteers organized an effort to protect Cascade Head from development. By 1966 they had raised funds and purchased the property, and then turned it over to The Nature Conservancy. Because of its ecological significance, Cascade Head Preserve and surrounding national forest and other lands won recognition in 1980 as a National Scenic Research Area and a United Nations Biosphere Reserve. Conservancy researchers are testing methods of maintaining and restoring grassland habitat for the Oregon silverspot butterfly, including prescribed fire. Conservancy ecologists also monitor the populations of rare plants throughout the year. In spring and summer, teams of volunt ...

Haplotype
A haplotype ( haploid genotype) is a group of alleles in an organism that are inherited together from a single parent. Many organisms contain genetic material ( DNA) which is inherited from two parents. Normally these organisms have their DNA organized in two sets of pairwise similar chromosomes. The offspring gets one chromosome in each pair from each parent. A set of pairs of chromosomes is called diploid and a set of only one half of each pair is called haploid. The haploid genotype (haplotype) is a genotype that considers the singular chromosomes rather than the pairs of chromosomes. It can be all the chromosomes from one of the parents or a minor part of a chromosome, for example a sequence of 9000 base pairs. However, there are other uses of this term. First, it is used to mean a collection of specific alleles (that is, specific DNA sequences) in a cluster of tightly linked genes on a chromosome that are likely to be inherited together—that is, they are likely to be con ...
