Salicornia Pacifica
''Salicornia pacifica'', also known as pickleweed, sea asparagus, Pacific swampfire, or glasswort, is a species of low-growing perennial succulent halophyte in the genus ''Salicornia'' found in the Pacific coast of North America and California. Description ''S. pacifica'' grows as erect shrubs possessing a well-developed primary central root system with few or no adventitious roots. It tends to flower between July and November. Distribution The species is native to salt marshes and alkaline soils throughout coastal California. It is occasionally found in Alaska and the East Coast. It occurs below 100 meters (330 feet) elevation. The genus is distributed globally. Ecology Pickleweed is specially adapted to use saltwater as its main source of water. When the saltwater is taken up, the salt is removed and stored in specialized vacuoles in the terminal segments. As the vacuoles become full of brine, they turn red and drop off the plant, removing the salt. Although pickleweed ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Halophyte
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes.Physiology of halophytes, T. J. FLOWERS, Plant and Soil 89, 41-56 (1985) An example of a halophyte is the salt marsh grass ''Spartina alterniflora'' (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in thehalophdatabase. The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity. Classification Halophytes can be classified in many ways. According to Stocker (1933), it is mainly of 3 kind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicornia
''Salicornia'' is a genus of succulent, halophytic (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. ''Salicornia'' species are native to North America, Europe, Central Asia, and southern Africa. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in ''Salicornia''. To French speakers in Atlantic Canada, they are known colloquially as ''titines de souris'' ('mouse tits'). The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus as sea beans, samphire greens or sea asparagus. Description The ''Salicornia'' species are small annual herbs. They grow prostrate to erect, their simple or branched stems are succulent, hairless, and appear to be jointed. The opposite leaves are strongly reduced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Alkaline
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lim ...

Vacuoles
A vacuole () is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution, though in certain cases they may contain solids which have been engulfed. Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these. The organelle has no basic shape or size; its structure varies according to the requirements of the cell. Discovery Contractile vacuoles ("stars") were first observed by Spallanzani (1776) in protozoa, although mistaken for respiratory organs. Dujardin (1841) named these "stars" as ''vacuoles''. In 1842, Schleiden applied the term for plant cells, to distinguish the structure with cell sap from the rest of the protoplasm. In 1885, de Vries named the vacuole membrane as tonoplast.

Salt Marsh Harvest Mouse
The salt marsh harvest mouse (''Reithrodontomys raviventris''), also known as the red-bellied harvest mouse, is an endangered rodent endemic to the San Francisco Bay Area salt marshes in California. The two distinct subspecies are both endangered and listed together on federal and state endangered-species lists. The northern subspecies (''R. r. halicoetes'') is lighter in color and inhabits the northern marshes of the bay, and the southern subspecies (''R. r. raviventris'') lives in the East and South Bay marshes. They are both quite similar in appearance to their congener species, the Western harvest mouse, ''R. megalotis'', to which they are not closely related. Genetic studies of the northern subspecies have revealed that the salt marsh harvest mouse is most closely related to the plains harvest mouse, ''R. montanus'', which occurs now in the Midwest. Its endangered designation is due to its limited range, historic decline in population and continuing threat of habitat loss d ...

Snowy Egret
The snowy egret (''Egretta thula'') is a small white heron. The genus name comes from Provençal French for the little egret, , which is a diminutive of , 'heron'. The species name ''thula'' is the Araucano term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.Jobling, 2010, p.143, 385 The snowy egret is the American counterpart to the very similar Old World little egret, which has become established in the Bahamas. At one time, the plumes of the snowy egret were in great demand as decorations for women's hats. They were hunted for these plumes and this reduced the population of the species to dangerously low levels. Now protected in the United States by law, under the Migratory Bird Treaty Act, this bird's population has rebounded. Description Adult snowy egrets are entirely white apart from the yellow lores between the long black bill and the eye, black legs, and bright yellow feet. The nape and neck bear long ...
