Japanese Temperate Rainforest
The Japanese temperate rainforest is located in the Japanese archipelago, in small batches over a wide range of islands, from Kyushu in the South to Hokkaido in the North. Due to its geographic features and climate, the Japanese temperate rainforest is very different from other temperate rainforests in the world. The islands in the Japanese archipelago comprise about 1/400 of the world’s land. The islands are located on a latitude that is normally dry; desert can be found elsewhere in the world at this latitude. However, the oceans surrounding Japan provide enough precipitation to maintain a temperate rainforest. General description Japanese temperate rainforest can be classified into three types: the warm temperate zone found in the southern islands and lower elevations in the north, the cool temperate zone found in the northern islands and higher elevations in the south, and the subalpine forest in the higher elevations of northern Honshu and Hokkaido. The distribution of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Archipelago
The Japanese archipelago ( Japanese: , ''Nihon Rettō'') is an archipelago of 14,125 islands that form the country of Japan. It extends over from the Sea of Okhotsk in the northeast to the East China and Philippine seas in the southwest along the Pacific coast of the Eurasian continent, and consists of three island arcs from north to south: the Northeastern Japan Arc, the Southwestern Japan Arc, and the Ryukyu Island Arc. The Daitō Islands, the Izu–Bonin–Mariana Arc, the Kuril Islands, and the Nanpō Islands neighbor the archipelago. Japan is the largest island country in East Asia and the fourth-largest island country in the world with . It has an exclusive economic zone of . Terminology The term " mainland Japan" is used to distinguish the large islands of the Japanese archipelago from the remote, smaller islands; it refers to the main islands of Hokkaido, Honshu, Kyushu and Shikoku. From 1943 until the end of the Pacific War, Karafuto Prefecture (south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called ''interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for t ...

Pinus Pumila
''Pinus pumila'', commonly known as the Siberian dwarf pine, dwarf Siberian pine, dwarf stone pine, Japanese stone pine, or creeping pine, is a tree in the family Pinaceae native to northeastern Asia and the Japanese isles. It shares the common name ''creeping pine'' with several other plants. Description The Siberian dwarf pine is a coniferous evergreen shrub ranging from in height, exceptionally up to , but may have individual branches that extend farther along the ground in length. In the mountains of northern Japan, it sometimes hybridises with the related Japanese white pine (''Pinus parviflora''); these hybrids (''Pinus'' × ''hakkodensis'') are larger than ''P. pumila'', reaching tall on occasion. The leaves are needle-like, formed in bundles of five and are 4–6 centimetres long. The cones are 2.5–4.5 cm long, with large nut-like seeds ( pine nuts).

Carex
''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial, although some species, such as '' C. bebbii'' and '' C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts ( caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...

Sasa Veitchii
is a species of flowering plant in the genus '' Sasa'', in the Poaceae family. Description ''Sasa veitchii'' is a large species of bamboo grass which may reach a height of 1-2m, with leaves about 20cm in length and 4-5cm in width. Young leaves are initially uniform green in color but develop light-colored edges as they mature overwinter. In its native Japan, it is found as a dense covering on some forest floors. The term ''kumazasa'' is not precise and can refer to a variety of bamboo grass species other than ''S.veitchii'', including ''S. kurilensis'', ''S. senanensis'', ''S. palmata'', and others. Uses This species is often planted in gardens as ornamental ground cover. The leaves can be used to make herbal tea, and are traditionally ground up and taken as a folk remedy for diabetes and hypertension, although there is no scientific consensus on its efficacy as medicine. In Ishikawa, Nagano, and Niigata prefectures, the leaves are used as wrapping for regional varieties of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thujopsis
''Thujopsis'' () is a genus of conifers in the cypress family (Cupressaceae), the sole member of which is ''Thujopsis dolabrata''. It is endemic to Japan, where it is named ''asunaro'' (). It is similar to the closely related genus '' Thuja'' (arborvitae), differing in the broader, thicker leaves and thick cones. It is also called hiba, false arborvitae, or hiba arborvitae. A popular allegory for the meaning behind ''asunaro'' is ''asu wa hinoki ni narou'' (), literally "tomorrow it will become a hinoki cypress", i.e. the tree looks like a smaller version of the common hinoki cypress. In Japan, other than being called asunaro, it also goes by the name ''hiba'' (). There are also a few regional variations, with asunaro being called ''ate'' () in Ishikawa, and ''atebi'' on Sado island. ''Thujopsis'' is a medium to large evergreen tree, reaching up to 40 m tall and 1.5 m trunk diameter, with red-brown bark which peels in vertical strips. The leaves are arranged in decussate pa ...

Chamaecyparis
''Chamaecyparis'', common names cypress or false cypress (to distinguish it from related cypresses), is a genus of conifers in the cypress family Cupressaceae, native to eastern Asia ( Japan and Taiwan) and to the western and eastern margins of the United States. The name is derived from the Greek ''khamai'' (χαμαί), meaning "on the earth", and ''kuparissos'' (κυπάρισσος) for "cypress". They are medium-sized to large evergreen trees growing from tall, with foliage in flat sprays. The leaves are of two types, needle-like juvenile leaves on young seedlings up to a year old, and scale-like adult leaves.
