Friedrich Anton Wilhelm Miquel
Friedrich Anton Wilhelm Miquel (24 October 1811 – 23 January 1871) was a Dutch botanist, whose main focus of study was on the flora of the Dutch East Indies. Early life Miquel was born in Neuenhaus and studied medicine at the University of Groningen, where, in 1833, he received his doctorate. After starting work as a doctor at the Buitengasthuis Hospital in Amsterdam, in 1835, he taught medicine at the clinical school in Rotterdam. In 1838 he became correspondent of the Royal Institute, which later became the Royal Netherlands Academy of Arts and Sciences, and in 1846 he became member. He was professor of botany at the University of Amsterdam (1846–1859) and Utrecht University (1859–1871). He directed the Rijksherbarium (National Herbarium) at Leiden from 1862. In 1866, he was elected a foreign member of the Royal Swedish Academy of Sciences. Research Miquel did research on the taxonomy of plants. He was interested in the flora of the Dutch Empire, specifically the Dutch E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myristicaceae
The Myristicaceae are a family of flowering plants native to Africa, Asia, Pacific islands, and the Americas and has been recognized by most taxonomists. It is sometimes called the "nutmeg family", after its most famous member, '' Myristica fragrans'', the source of the spices nutmeg and mace. The best known genera are '' Myristica'' in Asia and ''Virola'' in the Neotropics. The family consists of about 21 genera with about 520 species of trees, shrubs and rarely lianas ('' Pycnanthus'') found in tropical forests around the world. Most of the species are large trees that are valued in the timber industry. Description They are typically trees with reddish sap and distinctive pagoda-like growth (known as myristicaceous branching) in which horizontal branching only occurs at certain nodes along the main axis of the trunk, each node separated by a large gap where no branching occurs. All genera are dioecious, except '' Endocomia'' and some '' Iryanthera''. The inner bark is usual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java
Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site. Formed by volcanic eruptions due to geologic subduction of the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indonesia
Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at . With over 275 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population. Indonesia is a presidential republic with an elected legislature. It has 38 provinces, of which nine have special status. The country's capital, Jakarta, is the world's second-most populous urban area. Indonesia shares land borders with Papua New Guinea, East Timor, and the East Malaysia, eastern part of Malaysia, as well as maritime borders with Singapore, Vietnam, Thailand, the Philippines, Australia, Palau, an ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myristica
''Myristica'' is a genus of trees in the family Myristicaceae. There are over 150 species, distributed in Asia and the western Pacific. The type species of the genus, and the most economically important member, is ''Myristica fragrans'' (the nutmeg tree), from which mace is also derived. Etymology The name ' is from the Greek adjective , meaning ‘fragrant, for anointing’, referring to its early use. The adjective is from the noun (‘perfume, ointment, anointing oil’). Description All or nearly all species are dioecious. Knuth (1904) however cites a report of trees being male in their sex expression when young and female later. Perianth of one whorl of three largely united segments. Stamens two to thirty, partly or wholly united. The ovary is superior, consisting of a single uniovulate carpel.Secondary Pollen Presentation. page 7.

Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
