Tule Elk
The tule elk (''Cervus canadensis nannodes'') is a subspecies of elk found only in California, ranging from the grasslands and marshlands of the Central Valley to the grassy hills on the coast. The subspecies name derives from the tule (), a species of sedge native to freshwater marshes on which the Tule elk feeds. When the Europeans first arrived, an estimated 500,000 tule elk roamed these regions, but by 1870 they were thought to be extirpated. However, in 1874–1875 a single breeding pair was discovered in the tule marshes of Buena Vista Lake in the southern San Joaquin Valley. Conservation measures were taken to protect the species in the 1970s. Today, the wild population exceeds 4,000. Tule elk can reliably be found in Carrizo Plain National Monument, Point Reyes National Seashore, portions of the Owens Valley from Lone Pine to Bishop, on Coyote Ridge in Santa Clara Valley, San Jose, California and in Pacheco State Park and areas surrounding San Luis Reservoir near Los ...

Santa Clara Valley
The Santa Clara Valley is a geologic trough in Northern California that extends 90 miles (145 km) south–southeast from San Francisco to Hollister. The longitudinal valley is bordered on the west by the Santa Cruz Mountains and on the east by the Diablo Range; the two coastal ranges meet south of Hollister. The San Francisco Bay borders the valley to the north, and fills much of the northern third of the valley. The valley floor is an alluvial plain that formed in the graben (tectonic depression) between the San Andreas Fault to the west and the Hayward and Calaveras faults to the east. Within the valley and surrounding the bay on three sides are the urban communities of San Mateo County, Santa Clara County, and Alameda County, while the narrow southern reaches of the valley extend into rural San Benito County to Hollister. In practical terms, the central portion of the Santa Clara Valley is often considered by itself, contained entirely within Santa Clara County. The val ...

Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocky Mountain Elk
The Rocky Mountain elk (''Cervus canadensis nelsoni'') is a subspecies of elk found in the Rocky Mountains and adjacent ranges of Western North America. Habitat The winter ranges are most common in open forests and floodplain marshes in the lower elevations. In the summer it migrates to the subalpine forests and alpine basins. Elk have a diverse habitat range that they can reside in but are most often found in forest and forest edge habitat and in mountain regions they often stay in higher elevations during warmer months and migrate down lower in the winter. They may even come down the mountain and leave the forest into some grassland for part of the day but head back into the timber in the evening. Effects of climate change Climate change/warming can keep elk in their higher elevation habitats for longer into the winter than normal. Climate changes such as warming have in some cases even increased the seasonal range of elk in the winter. For example, in Yellowstone the climate ...

Monterey, California
Monterey (; es, Monterrey; Ohlone: ) is a city located in Monterey County on the southern edge of Monterey Bay on the U.S. state of California's Central Coast. Founded on June 3, 1770, it functioned as the capital of Alta California under both Spain (1804–1821) and Mexico (1822–1846). During this period, Monterey hosted California's first theater, public building, public library, publicly-funded school, printing-press, and newspaper. It was originally the only port of entry for all taxable goods in California. In 1846, during the Mexican–American War of 1846–1848, the United States Flag was raised over the Customs House. After Mexico ceded California to the U.S. at the end of the war, Monterey hosted California's first constitutional convention in 1849. The city occupies a land area of and the city hall is at above sea level. The 2020 census recorded a population of 30,218. Monterey and the surrounding area have attracted artists since the late 19th-century, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buttonwillow, California
Buttonwillow is an unincorporated community and census-designated place in the San Joaquin Valley, in Kern County, California. Buttonwillow is west of Bakersfield, at an elevation of ). The population was 1,508 at the 2010 census, up from 1,266 at the 2000 census. The center of population of California is located in Buttonwillow. History The town was originally called Buena Vista when it was founded in 1895, but the name quickly became Buttonwillow. Buttonwillow was named for the ''buttonbush'' ''(Cephalanthus occidentalis)''. A lone buttonbush served as a landmark on an old trans-valley trail and was used by ancient Yokuts Indian as a meeting place, later becoming the site of settlers' stock rodeos. The Miller & Lux holdings company eventually established a headquarters and store near the tree. This tree is listed as California Historical Landmark No. 492.

Suisun Bay
Suisun Bay ( ; Wintun for "where the west wind blows") is a shallow tidal estuary (a northeastern extension of the San Francisco Bay) in Northern California. It lies at the confluence of the Sacramento River and San Joaquin River, forming the entrance to the Sacramento–San Joaquin River Delta, an inverted river delta. To the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms a northern extension of Suisun Bay. Suisun Bay is directly north of Contra Costa County. The bay was named in 1811, after the Suisunes, a Patwin tribe of Wintun Indians. The Central Pacific Railroad built a train ferry that operated between Benicia and Port Costa, California, from 1879 to 1930. The ferry boats ''Solano'' and ''Contra Costa'' were removed from service when the nearby Martinez railroad bridge was completed in ...

California Department Of Fish And Wildlife
The California Department of Fish and Wildlife (CDFW), formerly known as the California Department of Fish and Game (CDFG), is a state agency under the California Natural Resources Agency. The Department of Fish and Wildlife manages and protects the state's wildlife, wildflowers, trees, mushrooms, algae (kelp) and native habitats (ecosystems). The department is responsible for regulatory enforcement and management of related recreational, commercial, scientific, and educational uses. The department also prevents illegal poaching. History The Game Act was passed in 1852 by the California State Legislature and signed into law by Governor John Bigler. The Game Act closed seasons in 12 counties for quail, partridge, mallard and wood ducks, elk, deer, and antelope. A second legislative action enacted the same year protected salmon runs. In 1854, the Legislature extended the act to include all counties of California. In 1860, protection controls were extended for trout. Lake Merritt ...

Owens River
The Owens River is a river in eastern California in the United States, approximately long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 17, 2011, It drains into and through the Owens Valley, an arid basin between the eastern slope of the Sierra Nevada and the western faces of the Inyo and White Mountains. The river terminates at the endorheic Owens Lake south of Lone Pine, at the bottom of a watershed. In the early 1900s, the Owens River was the focus of the California Water Wars, fought between the city of Los Angeles and the inhabitants of Owens Valley over the construction of the Los Angeles Aqueduct. Since 1913, the Owens River has been diverted to Los Angeles, causing the ruin of the valley's economy and the drying of Owens Lake. In winter 2006, the Los Angeles Department of Water and Power restored 5% of the pre-aqueduct flow to the river by court order, allowing the Owens River Gorge, the river bed in ...

Roosevelt Elk
The Roosevelt elk (''Cervus canadensis roosevelti)'', also known commonly as the Olympic elk and Roosevelt's wapiti, is the largest of the four surviving subspecies of elk (''Cervus canadensis'') in North America by body mass (although by antler size, both the Boone and Crockett (rifle) and Pope and Young (bow) records have Rocky Mountain elk being larger; none of the top 10 Roosevelt elk would score in the top 20 of Pope and Young's Rocky Mountain elk. In both species, mature bulls weigh from 700 to 1200 lbs. with very rare large bulls weighing more.) Its geographic range includes temperate rainforests of the Pacific Northwest, extending to parts of northern California. It was introduced to Alaska's Afognak, Kodiak, and Raspberry Islands in 1928 and reintroduced to British Columbia's Sunshine Coast from Vancouver Island in 1986. In December 1897, mammalogist C. Hart Merriam named the species after his friend Theodore Roosevelt, then Assistant Secretary of the US Navy. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
