Lavinia (fish)
The hitch (''Lavinia exilicauda'') is a cyprinid fish endemic to central California, and was once very common. The common name may derive from a Pomoan word for this species. It is the only species in the monospecific genus ''Lavinia''. Taxonomy The hitch was first formally described in 1854 by Spencer Fullerton Baird and Charles Frédéric Girard with its type locality given as the Sacramento River in California. While the hitch is closely related to the California roach (''Hesperoleucus symmetricus''), and the two species can hybridize, leading some authorities to place ''H. symmetricus'' in ''Lavinia'', genomic data appear to support the fishes' separate lineages. The ''Lavinia'' genus has been placed in the subfamily Leuciscinae of the family Cyprinidae in the 5th edition of '' Fishes of the World''. Other authorities classify the Leuciscidae as a family and place the genus ''Lavinia'' in the subfamily Laviniinae of that family. Three distinct population segments (DPS) ...

Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Pajaro River
The Pajaro River (''pájaro'' is ''bird'' in Spanish language, Spanish) is a U.S. river in the Central Coast (California), Central Coast region of California, forming part of the border between San Benito County, California, San Benito and Santa Clara County, California, Santa Clara Counties, the entire border between San Benito and Santa Cruz County, California, Santa Cruz County, and the entire border between Santa Cruz and Monterey County, California, Monterey County. Flowing roughly east to west, the river empties into Monterey Bay, west of Watsonville, California. History The first European land exploration of Alta California, the Spanish Portolà expedition, camped near the river for two nights, in the vicinity of today's community of Pajaro, California, Pajaro, on October 8–9, 1769. The party continued north the next day toward Santa Cruz. Expedition soldiers called it "Pajaro" (meaning "bird" in Spanish) because the natives they saw there had a large stuffed bird. Fr ...

Clear Lake (California)
Clear Lake (Pomo: ''Lypoyomi'') is a natural freshwater lake in Lake County in the U.S. state of California, north of Napa County and San Francisco. It is the largest natural freshwater lake wholly within the state, with of surface area. At an age of 2.5 million years, it is the oldest lake in North America. It is the latest lake to occupy a site with a history of lakes stretching back at least 2,500,000 years. Clear Lake supports large populations of largemouth bass, crappie, bluegill, carp and catfish. Two-thirds of the fish caught in Clear Lake are largemouth bass, with a record of . In addition to fish, there is abundant wildlife within the Clear Lake basin. There are year-round populations of ducks, pelicans, grebes, blue herons, egrets, osprey, and bald eagles, and the basin supports sizable populations of deer, bear, mountain lion, raccoon and other animals. The expansive, warm water of Clear Lake makes it popular for watersports, such as swimming, water skiing, wak ...

Russian River (California)
The Russian River (Southern Pomo: ''Ashokawna'', es, Río Ruso) is a southward-flowing river that drains of Sonoma and Mendocino counties in Northern California. With an annual average discharge of approximately 1,600,000 acre feet (2.0 km3), it is the second-largest river (after the Sacramento River) flowing through the nine-county Greater San Francisco Bay Area, with a mainstem long. Names The Southern Pomo know the river as Ashokawna (ʼaš:oʼkʰawna), "east water place" or "water to the east", and as Bidapte, "big river". Juan Rodríguez Cabrillo and his expedition may have travelled as far north as the Russian River in November 1542 before storms forced them to turn back south towards Monterey. The earliest Slavic name for the river, Slavyanka, appears on a Russian-American Company chart dated 1817. In 1827 the Spanish called it the San Ygnacio, and in 1843 the Spanish land grant referred to it as Rio Grande. The river takes its current name from Russian Iv ...

San Joaquin River
The San Joaquin River (; es, Río San Joaquín) is the longest river of Central California. The long river starts in the high Sierra Nevada, and flows through the rich agricultural region of the northern San Joaquin Valley before reaching Suisun Bay, San Francisco Bay, and the Pacific Ocean. An important source of irrigation water as well as a wildlife corridor, the San Joaquin is among the most heavily dammed and diverted of California's rivers. People have inhabited the San Joaquin Valley for more than 8,000 years, and it was long one of the major population centers of pre-Columbian California. Starting in the late 18th century, successive waves of explorers then settlers, mainly Spanish and American, emigrated to the San Joaquin basin. When Spain colonized the area, they sent soldiers from Mexico, who were usually of mixed native Mexican and Spanish birth, led by Spanish officers. Franciscan missionaries from Spain came with the expeditions to evangelize the natives by teac ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Salinas River (California)
The Salinas River ( Rumsen: ''ua kot taiauačorx'') is the longest river of the Central Coast region of California, running and draining . It flows north-northwest and drains the Salinas Valley that slices through the central California Coast Ranges south of Monterey Bay. The river begins in southern San Luis Obispo County, originating in the Los Machos Hills of the Los Padres National Forest. From there, the river flows north into Monterey County, eventually making its way to connect with the Monterey Bay, part of the Pacific Ocean, approximately south of Moss Landing. The river is a wildlife corridor, and provides the principal source of water from its reservoirs and tributaries for the farms and vineyards of the valley. Hydrology In 1769, when the river was first discovered by non-Native peoples via the Portola expedition, it was reported by them as being a "river watering a luxuriant plain" filled with fish weighing . As of the end of 2016, the river had been transformed ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Suisun Marsh
Located in northern California, the Suisun Marsh ( ) has been referred to as the largest brackish water marsh on west coast of the United States of America. The marsh land is part of the San Francisco Bay tidal estuary, and subject to tidal ebb and flood. The marsh is home to many species of birds and other wildlife, and is formed by the confluence of the Sacramento and San Joaquin rivers between Martinez and Suisun City, California and several other smaller, local watersheds. Adjacent to Suisun Bay, the marsh is immediately west of the legally defined Sacramento-San Joaquin Delta as well as part of the San Francisco Bay estuary. The Suisun Marsh is named for the Suisunes, a Patwin/Wintun sub-tribe, who inhabited the area around 200 years ago. Overview Suisun Marsh, 116,000 acres (470 km2) of land, bays, and sloughs, is one of the largest estuarine marshes in the western United States. Geologically, the Suisun Marsh is the product of water-borne sediment deposition, carri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Golden Shiner
The golden shiner (''Notemigonus crysoleucas'') is a cyprinid fish native to eastern North America. It is the sole member of its genus. Much used as a bait fish, it is probably the most widely pond-cultured fish in the United States. It can be found in Quebec, and its French name is "Mené jaune" or "Chatte de l'Est". Taxonomy It is the only North American member of the Old World clade within subfamily Leuciscinae. Description Though it has been known to reach lengths of , in the wild the golden shiner is usually between long. The body is laterally compressed (deep-bodied). The back is dark green or olive, and the belly is a silvery white. The sides are silver in smaller individuals, but golden in larger ones. There can be a faint dusky stripe along the sides. The anal fin is large and has 8-19 rays, while the dorsal fin comprises almost always 8 rays. Scales are relatively large and easily lost when the fish is handled. The mouth is small and upturned. Two characteristics can ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
