Pacific Flyway
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. Any given bird species travels roughly the same route every year, at almost the same time. Ornithologists and birdwatchers can often predict to the day when a particular species will show up in their area. Notable locations Along the Pacific Flyway, there are many key rest stops where birds of many species gather, sometimes in the millions, to feed and regain their strength before continuing. Some species may remain in these rest stops for the entire season, but most stay a few days before moving on. :''Notable locations include:'' * Boundary Bay, British Columbia, has been listed as an Important Bird Area by the Canadian government in recognition of its value to migratory bi ...

Lakes Of Siskiyou County, California
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archeological Site 4-SK-4
Archeological Site 4-SK-4, in Tulelake, California, near Macdoel, California, is a stratified archeological site that was a hunter-gatherer village on the west shores of the Lower Klamath Lake. The site is located in the heart of the Klamath Basin wetlands, west of Indian Tom Lake. It has also been known as Nightfire Island and as Sheepy Island. Modern Modocs have called the island ''Shapasheni'' (Shapash /xpni), meaning "where the sun and moon live", or "home of the sun and the moon. Prehistorically, it served as a village camp on a man-made mound in the wetlands and as a ceremonial site.Howe, 8-9 The site shows evidence of human occupancy from the peak of the Hypsithermal era, approximately 7,000 years ago. Archeologist have unearthed three villages one on top of the other through the centuries. Obsidian arrowheads are frequent finds, whose varieties include Northern Sided Notched, Elko type corner notched, and Gunther type points. Excavations and sampling started in 1966 by K ...

List Of Lakes In California
There are more than 3,000 named lakes, reservoirs, and dry lakes in the U.S. state of California. Largest lakes In terms of area covered, the largest lake in California is the Salton Sea, a lake formed in 1905 which is now saline. It occupies in the southeast corner of the state, but because it is shallow it only holds about of water. Tulare Lake in the San Joaquin Valley was larger, at approximately , until it was drained during the later years of the nineteenth century. In terms of volume, the largest lake on the list is Lake Tahoe, located on the California–Nevada border. It holds roughly of water. It is also the largest freshwater lake by area, at , and the deepest lake, with a maximum depth of . Among freshwater lakes entirely contained within the state, the largest by area is Clear Lake, which covers . Many of California's large lakes are actually reservoirs: artificial bodies of fresh water. In terms of both area and volume, the largest of these is Lake S ...

Alkalinity
Alkalinity (from ar, القلوي, al-qaly, lit=ashes of the saltwort) is the capacity of water to resist acidification. It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases. It is measured by titrating the solution with an acid such as HCl until its pH changes abruptly, or it reaches a known endpoint where that happens. Alkalinity is expressed in units of concentration, such as meq/L (milliequivalents per liter), μeq/kg (microequivalents per kilogram), or mg/L CaCO3 (milligrams per liter of calcium carbonate). Each of these measurements corresponds to an amount of acid added as a titrant. Although alkalinity is primarily a term used by oceanographers, it is also used by hydrologists to describe temporary hardness. Moreover, measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or ...

Eagle Lake (Lassen County)
Eagle Lake is a lake at elevation in Lassen County approximately north of Susanville, California. An endorheic alkaline lake, it is the second largest natural lake entirely in the state of California, United States. Ecology Eagle Lake is home to osprey (''Pandion haliaetus'') and bald eagles (''Haliaeetus leucocephalus''), from which it gets its name. Eagle Lake is the only watershed which supports native Eagle Lake trout (''Oncorhynchus mykiss aquilarum''). These rainbow trout grow to very large sizes, possibly having evolved to live longer as low flows often restrict spawning runs up their main spawning stream, Pine Creek. The average size of Eagle Lake trout are about and can exceed . Adults quickly grow to a size of in three years and can live for up to 11 years. Since these Modoc Lakes are high in alkalinity, the trout have evolved to be the only known trout subspecies capable of surviving in the alkaline waters of Eagle Lake. Eagle Lake Rainbow descendants, however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eagle Lake Trout
Eagle Lake trout, ''Oncorhynchus mykiss aquilarum'', is a subspecies of rainbow trout endemic to Eagle Lake, in Lassen County, California. It is a type of trout known for its ability to withstand high alkalinity.http://stevenojai.tripod.com/elrain.htm Eagle Lake Rainbow Its unique adaptations to the harsh environment of Eagle Lake make the fish a specialist with a very narrow environmental specificity. The Eagle Lake Trout is a State Species of Special Concern, but not considered endangered according to the Federal Endangered Species Act. Range The ''Eagle Lake trout'' name comes from its former exclusive-endemic Eagle Lake territory. Eagle lake is approximately 24,000 acres, making it one of the largest natural lakes in California. The streams and rivers that reach the lake only connect with the lake in the late spring after the snowmelt. The lake is highly basic, with an alkalinity of pH 8-9, making it uninhabitable for many aquatic species. The Eagle Lake trout have adapted t ...

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 ...

Lahontan Cutthroat Trout
Lahontan cutthroat trout (''Oncorhynchus clarkii henshawi'') is the largest subspecies of cutthroat trout, and the state fish of Nevada. It is one of three subspecies of cutthroat trout that are listed as federally threatened. Natural history The Lahontan cutthroat is native to the drainages of the Truckee River, Humboldt River, Carson River, Walker River, Quinn River and several smaller rivers in the Great Basin of North America. These were tributaries of ancient and massive Lake Lahontan during the ice ages until the lake shrank to remnants such as Pyramid Lake and Walker Lake about 7,000 years ago, although Lake Tahoe—from which the Truckee flows to Pyramid Lake—is still a large mountain lake. In this sense, Lahontan cutthroats essentially evolved in inland ocean-like conditions. Here, Lahontan cutthroats became a large (up to 1 m or 39 in) and moderately long-lived predator of chub suckers, and other fish as long as 30 or . The trout was able to remain a p ...

Brine Shrimp
''Artemia'' is a genus of aquatic crustaceans also known as brine shrimp. It is the only genus in the family Artemiidae. The first historical record of the existence of ''Artemia'' dates back to the first half of the 10th century AD from Urmia Lake, Iran, with an example called by an Iranian geographer an "aquatic dog," although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. ''Artemia'' populations are found worldwide in inland saltwater lakes, but not in oceans. ''Artemia'' are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the ''Artemia'' to produce dormant eggs, known as cysts, has led to extensive use of ''Artemia'' in aquaculture. The cysts may be stored indefinitely and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans. Nauplii of the brine shrimp ''Artemia' ...
