Tagoyano Shell Mound
The is an archaeological site in what is now the city of Tsugaru, Aomori Prefecture, in the Tōhoku region of northern Japan with an early Jōmon period shell midden. The site was designated a National Historic Site in 1944 by the Japanese government. It is a rare example of a shell midden to be found near the coast of the Sea of Japan. Overview During the early to middle Jōmon period (approximately 4000 to 2500 BC), sea levels were five to six meters higher than at present, and the ambient temperature was also 2 deg C higher. During this period, the Tōhoku region was inhabited by the Jōmon people, many of whom lived in coastal settlements. The middens associated with such settlements contain bone, botanical material, mollusc shells, sherds, lithics, and other artifacts and ecofacts associated with the now-vanished inhabitants, and these features, provide a useful source into the diets and habits of Jōmon society. Most of these middens are found along the Pacific coast o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lithic Flake
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often ( but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion. Since cores are often struck on an edge with a suitable angle (<90°) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pit Dwelling
A pit-house (or ''pit house'', ''pithouse'') is a house built in the ground and used for shelter. Besides providing shelter from the most extreme of weather conditions, these structures may also be used to store food (just like a pantry, a larder, or a root cellar) and for cultural activities like the telling of stories, dancing, singing and celebrations. General dictionaries also describe a pit-house as a ''dugout'', and it has similarities to a ''half-dugout''. In archaeology, a pit-house is frequently called a ''sunken-featured building'' and occasionally (grub-)hut or ''grubhouse'', after the German name ''Grubenhaus'' They are found in numerous cultures around the world, including the people of the Southwestern United States, the ancestral Pueblo, the ancient Fremont and Mogollon cultures, the Cherokee, the Inuit, the people of the Plateau, and archaic residents of Wyoming (Smith 2003) in North America; Archaic residents of the Lake Titicaca Basin (Craig 2005) in South Am ...

Short-tailed Albatross
The short-tailed albatross or Steller's albatross (''Phoebastria albatrus'') is a large rare seabird from the North Pacific. Although related to the other North Pacific albatrosses, it also exhibits behavioural and morphological links to the albatrosses of the Southern Ocean. It was described by the German naturalist Peter Simon Pallas from skins collected by Georg Wilhelm Steller (after whom its other common name is derived). Once common, it was brought to the edge of extinction by the trade in feathers, but with protection efforts underway since the 1950s, the species is in the process of recovering with an increasing population trend. Its breeding range, however, remains small. Taxonomy Short-tailed albatrosses are a type of albatross that belong to the family Diomedeidae, order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Sea Bass
The Japanese sea bass (''Lateolabrax japonicus'') is a species of catadromous marine ray-finned fish from the Asian sea bass family Lateolabracidae which is found in the Western Pacific. In Japan this species is known as . Description The Japanese sea bass has a slightly forked tail and a large mouth which has the lower jaw protruding beyond the upper jaw. The young fish have small black spots on the back and dorsal fin which tend to lost in larger fish. Its body has 12 to 15 spines in the first dorsal followed by 12 to 14 soft rays in its second dorsal. The anal fin has 3 spines and 7 to 9 soft rays. The maximum recorded total length is , although the more common standard length is and the maximum published weight is . Distribution The Japanese sea bass is found in the Western pacific where it occurs from Japan to the South China Sea.

Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bl ...

Corbicula Japonica
''Corbicula japonica'' is an edible species of brackishwater clam, a bivalve mollusk in the family Cyrenidae, the basket clams. The common names of the species include ''Shijimi'' (after its Japanese name), Japanese basket clam, or Japanese blue clam. Summary Japanese basket clams settle at the mouths of rivers in brackish water. During low tide, people are able to see them in tidal flats and collect them for food. Their shells are roughly 30-35mm and are reddish-brown while young, turning black as they mature. Their shells are glossy and have a tendency to grow concentric circles from their base, similar to Corbicula fluminea. The inside of their shells is purple when they are young and becomes white as they mature. Their reproduction is based on gonochorism. As food Shijimi and Asari (''Venerupis philippinarum'') are the most popular types of clam used in miso soup and Tsukudani in Japan.

Lake Jūsan
, also known locally as is a brackish-water Estuary#Lagoon-type or bar-built, lagoon-type estuary located in the city of Goshogawara in Aomori Prefecture, Japan. It is the third-largest lake in Aomori Prefecture, after Lake Towada and Lake Ogawara, with a shoreline of and a maximum depth of 3 meters. Etymology Per the Goshogawara city tourist bureau, the lagoon is called Lake Jusan because different rivers flow into it. However, other sources state that the name comes from the Ainu language word "To Sam", meaning the "shoreline of a lake". Hydrology The primary inflow to Lake Jūsan is the Iwaki River. Several small rivers also flow into the lagoon. The only outflow of the lagoon is to the Sea of Japan at the northwest corner of the lake, opposite to the mouth of the Iwaki River. Geology Lake Jūsan was formed after the end of a glacial period about 7,000 years ago. The retreating glaciers left behind sandy deposits that divided the estuary from the Sea of Japan.

Iwaki River
The is a river that crosses western Aomori Prefecture, Japan. It is in length and has a drainage area of . Under the Rivers Act of 1964 the Iwaki is designated as a Class 1 River and is managed by the Japanese Ministry of Land, Infrastructure, Transport and Tourism. The Iwaki River is the longest river in Aomori Prefecture, and is the source of irrigation for the large-scale rice and apple production of the prefecture. The Iwaki River, in the Tōhoku region north of the Fukushima Daiichi Nuclear Power Plant, remains unpolluted by radioactive materials after the Fukushima Daiichi nuclear disaster. Testing for caesium-134 and caesium-137 is carried out and published on a bimonthly basis. Geography The source of the Iwaki River is at Mount Ganmori () in the Shirakami-Sanchi region, a mountainous, unspoiled expanse of virgin forest which spans both Akita and Aomori Prefectures. The river flows eastward as a small mountain stream, then joins several tributaries to form the scenic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluvial Terrace
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers". These terraces lie parallel to and above the river channel and its floodplain. Because of the manner in which they form, fluvial terraces are underlain by fluvial sediments of highly variable thickness.Fairbridge, R. W., 1968, ''Encyclopedia of Geomorphology.'' Reinhold Book Company, New York.Blum, M., and T.E. Tonqvist, 2000, ''Fluvial responses to climate and sea-level change, a review and look forward.'' Sedimentology. v. 47 suppl. 1, pp. 2-48. River terraces are the remnants of earlier floodplains that existed at a time when either a stream or river was flowing at a higher elevation before its channel downcut to create a new floodplain at a lower elevation.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Diet (nutrition)
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity. Health A healthy diet can improve and maintain health, which can include aspects of mental and physical health. Specific diets, such as the DASH diet, can be used in treatment and management of chronic conditions. Dietar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
