Martinez, California Beavers
The Martinez beavers are a family of North American beavers living in Alhambra Creek in downtown Martinez, California. Best known as the longtime home of famed 19th/20th-century naturalist John Muir, Martinez has become a national example of urban stream restoration utilizing beavers as ecosystem engineers. In late 2006, a male and female beaver arrived in Alhambra Creek, proceeding to produce 4 kits over the course of the summer. After a decision by the City of Martinez to exterminate the beavers, local conservationists formed an organization called ''Worth a Dam'' and as a result of their activism, the decision was overturned. Subsequently, wildlife populations have increased in diversity along the Alhambra Creek watershed, most likely due to the dams maintained by the beavers. Alhambra Creek In late 2006, Alhambra Creek, which runs through the city of Martinez, was adopted by two beavers. The beavers built a dam 30 feet wide and at one time 6 feet high, and ch ...

Beaver Yearling Grooming Alhambra Creek 2008
Beavers are large, semiaquatic rodents in the genus ''Castor'' native to the temperate Northern Hemisphere. There are two extant species: the North American beaver (''Castor canadensis'') and the Eurasian beaver (''C. fiber''). Beavers are the second-largest living rodents after the capybaras. They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet and flat, scaly tails. The two species differ in the shape of the skull and tail and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams impound water and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ... [...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 of t ...

Fort Vancouver
Fort Vancouver was a 19th century fur trading post that was the headquarters of the Hudson's Bay Company's Columbia Department, located in the Pacific Northwest. Named for Captain George Vancouver, the fort was located on the northern bank of the Columbia River in present-day Vancouver, Washington. The fort was a major center of the regional fur trading. Every year trade goods and supplies from London arrived either via ships sailing to the Pacific Ocean or overland from Hudson Bay via the York Factory Express. Supplies and trade goods were exchanged with a plethora of Indigenous cultures for fur pelts. Furs from Fort Vancouver were often shipped to the Chinese port of Guangzhou where they were traded for Chinese manufactured goods for sale in the United Kingdom. At its pinnacle, Fort Vancouver watched over 34 outposts, 24 ports, six ships, and 600 employees. Today, a full-scale replica of the fort, with internal buildings, has been constructed and is open to the public as Fort Van ...

Fort Astoria
Fort Astoria (also named Fort George) was the primary fur trading post of John Jacob Astor's Pacific Fur Company (PFC). A maritime contingent of PFC staff was sent on board the '' Tonquin'', while another party traveled overland from St. Louis. This land based group later became known as the Astor Expedition. Built at the entrance of the Columbia River in 1811, Fort Astoria was the first American-owned settlement on the Pacific coast of North America. The inhabitants of the fort differed greatly in background and position, and were structured into a corporate hierarchy. The fur trading partners of the company were at the top, with clerks, craftsmen, hunters, and laborers in descending order. Nationalities included Americans, Scots, French Canadian voyageurs, Native Hawaiian Kanakas, and various indigenous North Americans, including Iroquois and others from Eastern Canada. They found life quite monotonous, with the fish and vegetable diet boring. Venereal diseases were problem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hudson's Bay Company
The Hudson's Bay Company (HBC; french: Compagnie de la Baie d'Hudson) is a Canadian retail business group. A fur trading business for much of its existence, HBC now owns and operates retail stores in Canada. The company's namesake business division is Hudson's Bay, commonly referred to as The Bay ( in French). After incorporation by English royal charter in 1670, the company functioned as the ''de facto'' government in parts of North America for nearly 200 years until the HBC sold the land it owned (the entire Hudson Bay drainage basin, known as Rupert's Land) to Canada in 1869 as part of the Deed of Surrender, authorized by the Rupert's Land Act 1868. At its peak, the company controlled the fur trade throughout much of the English- and later British-controlled North America. By the mid-19th century, the company evolved into a mercantile business selling a wide variety of products from furs to fine homeware in a small number of sales shops (as opposed to trading posts) acros ...

San Francisco Bay Area
The San Francisco Bay Area, often referred to as simply the Bay Area, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California. The Bay Area is defined by the Association of Bay Area Governments to include the nine counties that border the aforementioned estuaries: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties that do not border the bay such as Santa Cruz and San Benito (more often included in the Central Coast regions); or San Joaquin, Merced, and Stanislaus (more often included in the Central Valley). The core cities of the Bay Area are San Francisco, San Jose, and Oakland. Home to approximately 7.76 million people, Northern California's nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a comp ...

California Fur Rush
Before the 1849 California Gold Rush, American, English and Russian fur hunters were drawn to Spanish (and then Mexican) California in a California Fur Rush, to exploit its enormous fur resources. Before 1825, these Europeans were drawn to the northern and central California coast to harvest prodigious quantities of southern sea otter (''Enhydra lutris nereis'') and fur seals (''Callorhinus ursinus''), and then to the San Francisco Bay Area and Sacramento – San Joaquin River Delta to harvest beaver (''Castor canadensis''), river otter (''Lontra canadensis''), marten, fisher, mink, gray fox (''Urocyon cinereoargenteus''), weasel, and harbor seal. It was California's early fur trade, more than any other single factor, that opened up the West, and the San Francisco Bay Area in particular, to world trade. Coastal or maritime fur trade Just three years after Juan de Ayala sailed the first ship to pass through the Golden Gate in 1775, North America's Pacific Coast fur trade bega ...

Necropsy
An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death or to evaluate any disease or injury that may be present for research or educational purposes. (The term "necropsy" is generally reserved for non-human animals). Autopsies are usually performed by a specialized medical doctor called a pathologist. In most cases, a medical examiner or coroner can determine the cause of death. However, only a small portion of deaths require an autopsy to be performed, under certain circumstances. Purposes of performance Autopsies are performed for either legal or medical purposes. Autopsies can be performed when any of the following information is desired: * Determine if death was natural or unnatural * Injury source and extent on the corpse * Manner of death must be determined * Post mortem interval * Determining the decease ...

Hooded Merganser
The hooded merganser (''Lophodytes cucullatus'') is a species of merganser. It is the only extant species in the genus ''Lophodytes''. The genus name derives from the Greek language: ''lophos'' meaning 'crest', and ''dutes'' meaning 'diver'. The bird is striking in appearance; both sexes have crests that they can raise or lower, and the breeding plumage of the male is handsomely patterned and coloured. The hooded merganser has a sawbill but is not classified as a typical merganser. Hooded mergansers are the second-smallest species of merganser, with only the smew of Europe and Asia being smaller, and it also is the only merganser whose native habitat is restricted to North America. A species of fossil merganser from the Late Pleistocene of Vero Beach, Florida, was described as ''Querquedula floridana'' (a genus now included in ''Anas''), but upon reexamination turned out to be a species closely related to the hooded merganser; it is now named ''Lophodytes floridanus'', but th ...

Tule Perch
The tule perch ''Hysterocarpus traskii'' is a surfperch ( Embiotocidae) native to the rivers and estuaries of central California, United States of America. It is the sole member of its genus, and the only freshwater surfperch. The tule perch is small, at most in length, and deep-bodied, with a definite hump shape between the head and the dorsal fin. Color is variable, with a dark back that may have a bluish or purplish cast, and a whitish or yellowish belly. The sides may have a pattern of narrow or wide bars; the frequency of barred patterns varies according to subspecies. The dorsal fin has a noticeable ridge of scales running along its base, and consists of 15-19 spines followed by 9-15 soft rays. The anal fin has three spines and 20-16 soft rays, while the pectoral fins have 17-19 rays. They are fish of the lowlands, inhabiting lakes, sloughs, streams, and rivers, generally in areas with beds of vegetation or overhangs. They generally gather in groups, sometimes in large nu ...
