Pío Pico
Don Pío de Jesús Pico (May 5, 1801 – September 11, 1894) was a Californio politician, ranchero, and entrepreneur, famous for serving as the last governor of California (present-day U.S. state of California) under Mexican rule. A member of the prominent Pico family of California, he was one of the wealthiest men in California at the time and a hugely influential figure in Californian society. His legacy can be seen in the numerous places named after him, such as the city of Pico Rivera, Pico Boulevard in Los Angeles, Pio Pico State Historic Park, and the numerous schools that bear his name. Early years Pico, a member of the prominent Pico family of California, was born at Mission San Gabriel Arcángel to José María Pico and his wife María Eustaquia Gutiérrez, with the aid of midwife Eulalia Pérez de Guillén Mariné. His paternal grandmother, María Jacinta de la Bastida, was listed in the 1790 census as '' mulata'', meaning mixed race with African ancestry. His ...

Rivers Of Sonoma County, California
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs ...

Estero De San Antonio
Estero de San Antonio is a stream in the northern California counties of Marin and Sonoma which empties into Bodega Bay. Course The Estero springs just north of the Marin-Sonoma county line (from a hill overlooking Bloomfield, California) and runs south along Gericke Road into Marin County. Just north of Fallon-Two Rock Road, it turns west, flowing under the road just east of State Route 1. It flows south along the highway for , then crosses under the highway at milepost 47.6 and continues west to a confluence with Stemple Creek southeast of Fallon, California. From there, it winds its way westward, passing under Middle Road and Valley Ford Franklin School Road before emptying into Bodega Bay north of Dillon Beach, California. Ecology The Estero de San Antonio has a variety of habitat types, including freshwater ponds, mudflats, eelgrass and saltgrass area, and wooded ravines. It is estimated that the Estero has of associated wetlands. In the summer or early fall, a sandb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tee Beam
A T-beam (or tee beam), used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a -shaped cross section. The top of the -shaped cross section serves as a flange or compression member in resisting compressive stresses. The web (vertical section) of the beam below the compression flange serves to resist shear stress. When used for highway bridges the beam incorporates reinforcing bars in the bottom of the beam to resist the tensile stresses which occur during bending. The T-beam has a big disadvantage compared to an I-beam (with shape) because it has no bottom flange with which to deal with tensile forces. One way to make a T-beam more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab acts as the compression flange. History A T-beam is a structural element able to withstand large loads by resistance in the beam or by internal reinforcements. ...

Striped Bass
The striped bass (''Morone saxatilis''), also called the Atlantic striped bass, striper, linesider, rock, or rockfish, is an anadromous perciform fish of the family Moronidae found primarily along the Atlantic coast of North America. It has also been widely introduced into inland recreational fisheries across the United States. Striped bass found in the Gulf of Mexico are a separate strain referred to as Gulf Coast striped bass. The striped bass is the state fish of Maryland, Rhode Island, and South Carolina, and the state saltwater (marine) fish of New York, New Jersey, Virginia, and New Hampshire. The history of the striped bass fishery in North America dates back to the Colonial period. Many written accounts by some of the first European settlers describe the immense abundance of striped bass, along with alewives, traveling and spawning up most rivers in the coastal Northeast. Morphology and lifespan The striped bass is a typical member of the family Moronidae in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threespine Stickleback
The three-spined stickleback (''Gasterosteus aculeatus'') is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Many populations are anadromous (they live in seawater but breed in fresh or brackish water) and very tolerant of changes in salinity, a subject of interest to physiologists. It displays elaborate breeding behavior (defending a territory, building a nest, taking care of the eggs and fry) and it can be social (living in shoals outside the breeding season) making it a popular subject of inquiry in fish ethology and behavioral ecology. Its antipredator adaptations, host-parasite interactions, sensory physiology, reproductive physiology, and endocrinology have also been much studied. Facilitating these studies is the fact that the three-spined stickleback is easy to find in natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Roach
The California roach (''Hesperoleucus symmetricus'') is a cyprinid fish native to western North America and abundant in the intermittent streams throughout central California. Once considered the sole member of its genus, it has recently been split into a number of closely related species and subspecies.Baumsteiger J, Moyle PB 2019A reappraisal of the California Roach/Hitch (Cypriniformes, Cyprinidae, Hesperoleucus/Lavinia) species complexZootaxa 4543 (2): 221–240 Characteristics of fish in the ''Hesperoleucus symmetricus'' species complex These fishes are of a relatively chunky body shape, with a largish head and large eyes, but a small mouth oriented downwards. The color is a darker grayish-bluish above, and a dull silver underneath. During the breeding season, red-orange patches appear on the chin, operculum, and at the bases of pectoral, pelvic, and anal fins. The smallish dorsal fin has 7-10 rays, while the anal fin has 6-9 rays. They never get large, the maximum known b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steelhead Trout
Steelhead, or occasionally steelhead trout, is the common name of the anadromous form of the coastal rainbow trout or redband trout (O. m. gairdneri). Steelhead are native to cold-water tributaries of the Pacific basin in Northeast Asia and North America. Like other sea-run (anadromous) trout and salmon, steelhead spawn in freshwater, smolts migrate to the ocean to forage for several years and adults return to their natal streams to spawn. Steelhead are iteroparous, although survival is approximately 10–20%. Description The freshwater form of the steelhead is the rainbow trout (''Oncorhynchus mykiss''). The difference between these forms of the species is that steelhead migrate to the ocean and return to freshwater tributaries to spawn, whereas non-anadromous rainbow trout do not leave freshwater. Steelhead are also larger and less colorful than rainbow trout, and can weigh up to and reach in length. They can live up to 11 years and spawn multiple times. The body ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
