San Clemente Island
San Clemente Island (Tongva: ''Kinkipar''; Spanish: ''Isla de San Clemente'') is the southernmost of the Channel Islands of California. It is owned and operated by the United States Navy, and is a part of Los Angeles County. It is administered by Naval Base Coronado. It is long and has of land. The 2018 census estimates 148 military and civilian personnel reside on the island. The city of San Clemente in Orange County, California is named after the island. Geography Topography Geologically, the island is described as being "the upper part of a tilted and gently arched northwestward-trending block of the earth's crust that has a straight, steep northeastern slope and a more irregular and much gentler southwestern slope" that is composed primarily of volcanic rock, with the northeast boundary of the island having a large fault that parallels most of the major faults on the California mainland. San Clemente Island has some of the best examples of marine terraces, and has trench-li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tongva Language
The Tongva language (also known as Gabrielino or Gabrieleño) is an extinct Uto-Aztecan language formerly spoken by the Tongva, a Native American people who live in and around Los Angeles, California. It has not been a language of everyday conversation since the 1940s. The Gabrielino people now speak English but a few are attempting to revive their language by using it in everyday conversation and ceremonial contexts. Presently, Gabrielino is also being used in language revitalization classes and in some public discussion regarding religious and environmental issues. Tongva is closely related to Serrano. The last fluent native speakers of Tongva lived in the early 20th century. The language is primarily documented in the unpublished field notes of John Peabody Harrington made during that time. The "J.P. Harrington Project", developed by the Smithsonian through UC Davis, approximately 6,000 pages of his notes on the Tongva language, were coded for documentation by a Tongva member ...

Endemic (ecology)
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] |
Lithophragma Maximum
''Lithophragma maximum'', known by the common name San Clemente Island woodland star, is a rare species of flowering plant in the saxifrage family. It is endemic to San Clemente Island, one of the eight Channel Islands of California. It is known from only about four kilometers of rocky coastal cliffs on the edge of the island.Furches, M.S., et al. (2009)High genetic divergence characterizes populations of the endemic plant ''Lithophragma maximum'' (Saxifragaceae) on San Clemente Island ''Conservation Genetics'' 10:115-26. The plant was thought to be extinct until a few specimens were rediscovered in 1979.USFWSDetermination of Endangered Status for Three Plants from the Channel Islands of Southern California.Federal Register. August 8, 1997. Only 200 individuals were tallied in a 1996 survey. In 1997 the plant was listed as an endangered species on the federal level.

Triteleia Clementina
''Triteleia clementina'' is a rare species of flowering plant known by the common name San Clemente Island triteleia. It is endemic to San Clemente Island, one of the Channel Islands of California, where it is known from about twenty occurrences. Its habitat includes moist, rocky, seaside grassland. It is a perennial herb growing from a corm. It produces two or three keeled, lance-shaped leaves up to 100 centimeters long by three wide. The inflorescence arises on an erect stem up to 90 centimeters tall and bears an umbel-like cluster of many flowers. Each flower is a funnel-shaped lavender or light blue bloom with six lobes measuring up to 1.5 centimeters long. There are six stamens with purple anthers.

Brodiaea Kinkiensis
''Brodiaea kinkiensis'' is a species of ''Brodiaea'' also with the common name San Clemente Island brodiaea. This flower is endemic to San Clemente Island, one of the Channel Islands of California. This flower is not considered endangered, but it is of some concern since its entire wild distribution is limited to the clay mesas of San Clemente Island. Description It has one cylindrical leaf alongside a tall stem which bears an inflorescence of one to several bell-shaped blooms. Each flower has six petallike tepals A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very ... in shades of light purple with darker purple longitudinal stripes or streaks.

Bell's Sparrow
Bell's sparrow (''Artemisiospiza belli'') is a medium-sized sparrow of the western United States and northwestern Mexico. It used to be placed in the genus ''Amphispiza'', but recent evidence suggested it be placed in its own genus. Four populations are resident to the west: subspecies ''canescens'' breeds in south-central California, the dark nominate subspecies ''belli'' in the California Coast Ranges and part of the western slope of the Sierra Nevada south to about 29°N in Baja California, the equally dark subspecies ''clementeae'' limited to San Clemente Island, and subspecies ''cinerea'' in western Baja California from 29°N to 26°45′N. The AOU now considers Bell's sparrow a separate species, formerly grouped with the sagebrush sparrow, and together previously known as the sage sparrow. Characteristics Bell's sparrow is difficult to separate in the field from the sagebrush sparrow. Both species measure about long and weigh approximately . In general, with Bell's S ...

Kelp Forest
Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth.Mann, K.H. 1973. Seaweeds: their productivity and strategy for growth. Science 182: 975-981. Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global Primary production, primary productivity. Kelp forests occur worldwide throughout temperate and polar region, polar coastal oceans. In 2007, kelp forests were also discovered in tropical waters near Ecuador.Graham, M.H., B.P. Kinlan, L.D. Druehl, L.E. Garske, and S. Banks. 2007. Deep-water kelp refugia as potential hotspots of tropical marine diversity and productivity. Proceedings of the National Academy of Sciences 104: 16576-16580.

Hydrocoral
Anthoathecata, or the athecate hydroids, are an order of hydrozoans belonging to the phylum Cnidaria. A profusion of alternate scientific names exists for this long-known, heavily discussed, and spectacular group. It has also been called Gymnoblastea and (with or without an emended ending ''-ae''), Anthomedusa, Athecata, Hydromedusa, and Stylasterina. There are about 1,200 species worldwide.Schuchert, P. (2014). Anthoathecata. Accessed through: Schuchert, P. (2014) World Hydrozoa database at http://www.marinespecies.org/hydrozoa/aphia.php?p=taxdetails&id=13551 on 2014-10-31 These hydrozoans always have a polyp stage. Their hydranths grow either solitary or in colonies. There is no firm perisarc around the polyp body. The medusae, or jellyfish, are solitary animals, with tentacles arising from the bell margin, lacking statocysts but possessing radial canals. Their gonads are on the manubrium ("handle").Bouillon, J.; Gravili, C.; Pagès, F.; Gili, J.-M.; Boero, F. (2006). An intro ...

California Spiny Lobster
The California spiny lobster (''Panulirus interruptus'') is a species of spiny lobster found in the eastern Pacific Ocean from Monterey Bay, California, to the Gulf of Tehuantepec, Mexico. It typically grows to a length of and is a reddish-brown color with stripes along the legs, and has a pair of enlarged antennae but no claws. The interrupted grooves across the tail are characteristic for the species. Females can carry up to 680,000 eggs, which hatch after 10 weeks into flat ''phyllosoma'' larvae. These feed on plankton before the metamorphosis into the juvenile state. Adults are nocturnal and migratory, living among rocks at depths of up to , and feeding on sea urchins, clams, mussels and worms. The spiny lobster is eaten by various fish, octopuses and sea otters, but can defend itself with a loud noise produced by its antennae. The California spiny lobster is the subject of both commercial and recreational fishery in both Mexico and the United States, with sport fishermen ...

Sea Lion
Sea lions are pinnipeds characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short and thick hair, and a big chest and belly. Together with the fur seals, they make up the family Otariidae, eared seals. The sea lions have six extant and one extinct species (the Japanese sea lion) in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. They have an average lifespan of 20–30 years. A male California sea lion weighs on average about and is about long, while the female sea lion weighs and is long. The largest sea lions are Steller's sea lions, which can weigh and grow to a length of . Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about ) at a single feeding. Sea lions can move around in water and at their fastest they can reach a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Clemente Island Goat
The San Clemente Island goat is a type of domestic goat derived from feral goats isolated on San Clemente Island, one of the Channel Islands of California. History The long-isolated feral goats of the Channel Islands, including the San Clemente Island goat and the Santa Catalina Island goat, are thought to be descendants of goats brought to the islands by Spanish missionaries and settlers; breeds such as the La Blanca Celtiboras, the La Castellana Extremenas, and later the more common dairy and meat goats of Spain, the Malaguenas and Murcianas. They first arrived on San Clemente from Santa Catalina Island, in 1875, and there they remained feral until the United States Navy, which was under a directive to preserve the endangered flora and fauna of the island that were threatened by the grazing of nonendemic species, sought their removal. After initial trapping and hunting failed to eliminate the goats, the Navy began a shooting program to exterminate them. This was blocked in co ...
