Olympic Shrew
The Olympic shrew (''Sorex rohweri'') is a rare species of shrew that lives in only 13 spots in northwest Washington state and, a recent discovery, in Burns Bog, located in Delta, BC. Not much is known about this species. It was only described in 2007 and is often mistaken for the masked shrew, ''Sorex cinereus''. Recent reexaminations of museum specimens show the species occurs in British Columbia in the Fraser Valley south of the Fraser River, east to Chilliwack Lake.Nagorsen, David and N. Panter. 2009.

Shrew
Shrews (family Soricidae) are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders. Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are. It is, in fact, a much closer relative of hedgehogs and moles; shrews are related to rodents only in that both belong to the Boreoeutheria magnorder. Shrews have sharp, spike-like teeth, whereas rodents have gnawing front incisor teeth. Shrews are distributed almost worldwide; among the major tropical and temperate land masses, only New Guinea, Australia, and New Zealand have no native shrews; in South America shrews appeared only relatively recently, as a result of the Great American Interchange, and are present only in the northern Andes. The shrew family has 385 known species, making it the fourth-most spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burns Bog
Burns Bog is an ombrotrophic peat bog located in Delta, British Columbia, Canada. It is the largest raised peat bog and the largest undeveloped urban land mass on the West Coast of the Americas. Burns Bog was originally before development. Currently, only remain of the bog. Burns Bog is habitat to more than 300 plant and animal species, and 175 bird species. Some of these animals are listed as endangered (i.e. red-listed) or vulnerable (i.e. blue-listed) under the BC Provincial Government Species at-risk designations. The bog is also a major migratory stopover for various bird species on the Pacific Flyway. Burns Bog regulates water as well. The bog prevents flooding, maintains cool water temperatures in nearby rivers, holds water, and releases water in dry conditions. Burns Bog is an estuarine bog since it is situated at the mouth of the Fraser River and next to the Pacific Ocean. Ecology Characteristics The major characteristics of Burns Bog is that it is wet, acidi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta, BC
Delta is a city in the Lower Mainland region of British Columbia, Canada, as part of Greater Vancouver. Located on the Fraser Lowland south of Fraser River's south arm, it is bordered by the city of Richmond on the Lulu Island to the north, New Westminster to the northeast, Surrey to the east, the Boundary Bay and the American pene-exclave Point Roberts to the south, and the Strait of Georgia to the west. Encompassing the nearby Annacis Island, Deas Island and Westham Island, Delta is mostly rural and officially composed of three distinct communities: North Delta, Ladner and Tsawwassen. History Prior to European settlement, Delta's flatlands and coastal shores were inhabited by the Tsawwassen First Nation of the Coast Salish. The land was first sighted by Europeans in 1791, when Spanish explorer Lieutenant Francisco de Eliza mistook the area for an island and named it "Isla de Cepeda". The first European settler in Delta was James Kennedy who pre-empted 135 acres in what later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masked Shrew
The cinereus shrew or masked shrew (''Sorex cinereus'') is a small shrew found in Alaska, Canada, and the northern United States. This is the most widely distributed shrew in North America, where it is also known as the common shrew. Description It is grey-brown in colour with a light grey underside and a pointed snout. It has a long tail that is brown on top and pale underneath with a dark tip. Its body is about in length including a long tail. It weighs about . It has darker colouring than other shrews. Masked shrews can live up to two years, but, on average, only survive eighteen months. In a long-term study done in Alaska, Yom-Tov and colleagues (2005) found that the masked shrew's body size contradicts Bergmann's Rule. The study, done on 650 specimens and spanning from 1950 to 2003, examined body size in relation to ambient temperature. Measurements of body weight and the length of the tail, ear, hind foot, and body were taken. Results yielded that the masked shrew's bo ...

Gateway Program
The Gateway Program is a C$3.0 billion regional transportation project for Metro Vancouver that is being managed by the British Columbia Ministry of Transportation. The ministry introduced the Gateway Program on January 31, 2006, as a means to address growing congestion and reduce travel times. Port Mann / Highway 1 The Port Mann / Highway 1 (PMH1) Project includes the widening of Highway 1, a new Port Mann Bridge, and upgrades to interchanges on British Columbia Highway 1 in order to address congestion through this corridor. The Port Mann Bridge was replaced with a new 10-lane tolled bridge. On September 1, 2017, the toll was removed. The project will also feature rapid bus lanes. This will include transit priority access to Highway 1, park-and-ride facilities, new transit loops in Surrey and Langley, and 20 new buses. The bridge will include separated pedestrian and cycling lanes and is also designed to accommodate the eventual addition of light rail transit underneath th ...

Sorex
The genus ''Sorex'' includes many of the common shrews of Eurasia and North America, and contains at least 142 known species and subspecies. Members of this genus, known as long-tailed shrews, are the only members of the tribe Soricini of the subfamily ''Soricinae'' (red-toothed shrews). They have 32 teeth. These animals have long, pointed snouts, small ears, which are often not visible, and scent glands located on the sides of their bodies. As their eyesight is generally poor, they rely on hearing and smell to locate their prey, mainly insects. Some species also use echolocation. Distinguishing between species without examining the dental pattern is often difficult. In some species, a female shrew and her dependent young form "caravans", in which each shrew grasps the rear of the shrew in front, when changing location. Species * Genus ''Sorex'' – most basal of the genera ** Kashmir pygmy shrew (''S. planiceps'') – India and Pakistan ** Tibetan shrew (''S. thibetanus'') â ...
