Hesperoleucus
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.

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Leuciscinae
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows. Members of the Old World (OW) clade of minnows within this subfamily are known as European minnows. As the name suggests, most members of the OW clade are found in Eurasia, aside from the golden shiner (''Notemigonus crysoleucas''), which is found in eastern North America. According to ancestral area reconstruction, the subfamily Leuiciscinae is thought to have originated in Europe before becoming widely distributed in parts of Europe, Asia and North America. Evidence for the dispersal of this subfamily can be marked by biogeographical scenarios/observations, geomorphological changes, phylogenetic relationships as well as evidence for vicariance events taking place through time. Through analyses and evidence of divergence time, it was observed that the two monophyletic groups, the phoxinins and the leuciscins, had shared a common ancestor dating to approximately 70.7 million year ...

John Otterbein Snyder
John Otterbein Snyder (August 14, 1867 – August 19, 1943) was an American ichthyologist and professor of zoology at Stanford University. History As a student he met David Starr Jordan who inspired him to enter zoology. He eventually became a zoology instructor at Stanford University and served there from 1899 until 1943. He went on several major collecting expeditions aboard the in the early 1900s and organized the U.S. National Museum's fish collection in 1925. The same year he also declined the directorship there so he could return to Stanford. He was a long-term member of the California Academy of Sciences and worked for the California Bureau of Fisheries. He wrote many articles and papers as well as describing several new species of sharks. San Francisco Bay In 1905, Snyder, then Assistant Professor of Zoology at Stanford, published ''Notes on the fishes of the streams flowing into San Francisco Bay'' in ''Report of the Commissioner of Fisheries to the Secretary of Comme ...

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 ...

Fish Of North America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Warner Valley
The Warner Valley is a valley in south-central Oregon in the United States. It is a remote valley at the northwestern corner of North America's Basin and Range Province. The valley is home to a chain of lakes and wetlands known as the Warner Lakes. Native Americans were present in the Warner Valley for thousands of years before European explorers arrived in the 19th century. It is the site of Fort Warner, built by the United States Army in 1867. The fort was used as a supply depot and administrative headquarters during a protracted Army campaign against Northern Paiute bands in eastern Oregon and northern California. Today, livestock ranching is the main commercial activity in the valley. The Warner Valley offers a number of recreational opportunities including hunting, fishing, bird watching, and wildlife viewing. Geography The Warner Valley is located in south-central Oregon. It is approximately long and wide. Most of the valley is in Lake County; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permanente Creek
Permanente Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed February 3, 2013 stream originating on Black Mountain in Santa Clara County, California, United States. It is the namesake for the Kaiser Permanente health maintenance organization. Named by early Spanish explorers as Arroyo Permanente or Rio Permanente because of its perennial flow, the creek descends the east flank of Black Mountain then courses north through Los Altos and Mountain View, discharging into southwest San Francisco Bay historically at the Mountain View Slough but now partly diverted via the Permanente Creek Diversion Channel to Stevens Creek and the Whisman Slough in San Francisco Bay. History The Ohlone Indians lived in the area for over 3,000 years prior to the arrival of the Europeans. A large village, known as Partacsi, was located in this general area. An expedition led by Colonel Juan Bautista de Anza passed through this area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adobe Creek (near Los Altos, California)
Adobe Creek, historically San Antonio Creek, is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 15, 2011 northward-flowing stream originating on Black Mountain in the Santa Cruz Mountains. It courses through the cities of Los Altos Hills, Los Altos, and Palo Alto on its way to the Palo Alto Flood Basin and thence to southwestern San Francisco Bay in Santa Clara County, California, United States. Historically, Adobe Creek was a perennial stream and hosted runs of steelhead trout entering from the Bay, but these salmonids are now blocked by numerous flood control structures, including a tidal gate at the creek's mouth and a long concretized rectangular channel culminating in an impassable drop structure at El Camino Real. The co-founders of Adobe Systems both lived on Adobe Creek. History The Ohlone people were the original inhabitants of Adobe Creek. A large shell mound which once had a group of Indian hut ...

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] |
