Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an England, English botany, botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle, North Yorkshire, Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury (naturalist), John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Rams ...

Silver Strand (San Diego)
Silver Strand, or simply The Strand, is a low, narrow, sandy isthmus or tombolo long in San Diego County, California partially within the Silver Strand State Beach. It connects Coronado Island with Imperial Beach. Together with the Point Loma peninsula it shelters and defines San Diego Bay. State Route 75 (SR 75) runs the length of the strand and is a popular site for jogging and bicycling. The Silver Strand Half Marathon is run along the route each November. Silver Strand State Beach, which encompasses both the San Diego Bay and Pacific Ocean sides of the strand, is a little farther off the beaten path of the highly popular beaches in Ocean Beach and Mission Beach, offering more solitude for those who wish to avoid beach crowds. The ocean side of the strand features of coastline trimmed with silver shells (thus named Silver Strand). Beach The Silver Strand State Beach is just south of Coronado on SR 75. The beach offers many activities including camping, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By John Torrey
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Without Expected TNC Conservation Status
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. 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 first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malacothrix (plant)
''Malacothrix'' is a genus of plants in the tribe Cichorieae within the family Asteraceae. They are known generally as desert dandelions or desertdandelions. Most are native to western North America although a few have been introduced to South America. Several are found only on offshore islands in the Pacific.''Malacothrix''. Flora of North America. Phylogenetics, Phylogenetic analysis demonstrates that ''Malacothrix'' is not monophyly, monophyletic. Some of its species are related to ''Atrichoseris'', whereas a second group is more closely related to ''Anisocoma'' and ''Calycoseris''.Lee, J., et al.

Silver Strand Beach
Silver Strand Beach is an unincorporated beach neighborhood in Ventura County, California, United States. Lying between the mouth of Channel Islands Harbor on the north and the ocean entrance to the Port of Hueneme on the south, the eastern side of the beach community lies along the boundary of the Naval Construction Battalion Center Port Hueneme. The harbors and the Naval base almost completely surround Silver Strand, keeping the area relatively separate from the city of Oxnard and making it accessible by only one main road, Victoria Avenue. For statistical purposes, the United States Census Bureau has combined Silver Strand with two other historic neighborhoods, Hollywood Beach and Hollywood by the Sea, to define a census-designated place (CDP) named Channel Islands Beach. Because of its location near an open water trench, it is common to see a large array of marine life including dolphins, seals, and jellyfish. Silver Strand is also home to the Oxnard Base of the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Channel Islands (California)
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park, and the waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. The islands were inhabited as early as 13,000 years ago, the earliest paleontological evidence of humans in North America. They are the easternmost islands in the Pacific Island group. The Chumash and Tongva Native Americans who lived later on the islands may be the descendants of the original inhabitants, but they were then displaced by Spaniards who used the islands for fishing and agriculture.
