Cryptomeria
''Cryptomeria'' (literally "hidden parts") is a monotypic genus of conifer in the cypress family Cupressaceae. It includes only one species, ''Cryptomeria japonica'' ( syn. ''Cupressus japonica'' L.f.). It is considered to be endemic to Japan, where it is known as . The tree is also called Japanese cedar or Japanese redwood in English. It has been extensively introduced, and cultivated for wood production on the Azores and elsewhere. Description ''Cryptomeria'' is a very large evergreen tree, reaching up to tall and trunk diameter, with red-brown bark which peels in vertical strips. The leaves are arranged spirally, needle-like, long; and the seed cones globular, diameter with about 20–40 scales. It is superficially similar to the related giant sequoia (''Sequoiadendron giganteum''), from which it can be differentiated by the longer leaves (under in the giant sequoia) and smaller cones ( in the giant sequoia), and the harder bark on the trunk (thick, soft and spong ...

Hay Fever In Japan
is most commonly caused by pollen from ''Cryptomeria japonica'' (known as ''sugi'' in Japanese and often translated as "cedar" though it is not a member of the Cedrus genus) and Japanese cypress (known as ''hinoki''), two native Japanese tree species. According to the Ministry of the Environment, as of 2019, 42.5% of Japanese suffer from some form of hay fever, and 38.8% suffer from cedar pollinosis. Cause Hay fever was relatively uncommon in Japan until the early 1960s. Shortly after World War II, reforestation policies resulted in large forests of cryptomeria and Japanese cypress trees, which were an important resource for the construction industry. As these trees matured, they started to produce large amounts of pollen. Peak production of pollen occurs in trees of 30 years and older. As the Japanese economy developed in the 1970s and 1980s, cheaper imported building materials decreased the demand for cryptomeria and Japanese cypress materials. This resulted in increasing for ...

Moth
Moths are a group of insects that includes all members of the order Lepidoptera that are not Butterfly, butterflies. They were previously classified as suborder Heterocera, but the group is Paraphyly, paraphyletic with respect to butterflies (suborder Rhopalocera) and neither subordinate taxon is used in modern classifications. Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although there are also crepuscular and Diurnal animal, diurnal species. Differences between butterflies and moths While the Butterfly, butterflies form a monophyly, monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae a ...

Larva
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle. A larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the lar ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tianmu Mountain
Tianmu Mountain, Mount Tianmu, or Tianmushan () is a mountain in Lin'an County west of Hangzhou, Zhejiang, in eastern China. It is made up of two peaks: West Tianmu () and East Tianmu (). Twin ponds near the top of the peaks led to the name of the mountain. China's Tianmu Mountain National Nature Reserve lies on the northwest portion of the mountain. It is a UNESCO Biosphere Reserve as part of UNESCO's Man and the Biosphere Programme. Tianmu is known for giant Japanese cedars, waterfalls, Tianmu tea, peaks surrounded by clouds, bamboo shoots, temples and nunneries, and odd-shaped rocks. More than 2,000 species of plants grow on the mountain, including (on West Tianmu) the last surviving truly wild population of Ginkgo trees. Prominent among the Japanese cedars is the "Giant Tree King", named by the Qianlong Emperor of the Qing. In 2009, it measured in height, in diameter, and in volume. The mountain is also home to hundreds of species of birds and animals, including 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernest Henry Wilson
Ernest Henry "Chinese" Wilson (15 February 1876 – 15 October 1930), better known as E. H. Wilson, was a British plant collector and explorer who introduced a large range of about 2,000 Asian plant species to the Western culture, West; some sixty bear his name. Career Wilson was born in Chipping Campden, Gloucestershire but the family soon moved to Shirley, Warwickshire, where they set up a floristry business. He left school early for employment at the local nursery of Messrs. Hewitt, Warwickshire, as apprentice gardener, and, aged 16, at the Birmingham Botanical Gardens (United Kingdom), Birmingham Botanical Gardens; there he also studied at Aston University, Birmingham Municipal Technical School in the evenings, receiving the Queen's Prize for botany. In 1897 he began work at the Royal Botanic Gardens, Kew, where he won the Joseph Dalton Hooker, Hooker Prize for an essay on conifers. He then accepted a position as Chinese plant collector with the Veitch Nurseries, firm of Jam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequoiadendron Giganteum
''Sequoiadendron giganteum'' (also known as the giant sequoia, giant redwood, Sierra redwood or Wellingtonia) is a species of coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the largest trees on Earth. They are native to the groves on the western slopes of the Sierra Nevada (U.S.), Sierra Nevada mountain range of California but have been introduced, planted, and grown around the world. The giant sequoia is listed as an endangered species by the International Union for Conservation of Nature, IUCN with fewer than 80,000 remaining in its native California. The tree was introduced to the U.K. in 1853, and by now might have 500,000 trees growing there where it is more commonly known as Wellingtonia after the Duke of Wellington. The giant sequoia grow to an average height of 50–85 m (164–279 ft) with trunk diameters ranging from 6–8 m (20–26 ft). Record trees have been measured at 94.8 m (311&nbs ...

Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...
