Common Pawpaw
''Asimina triloba'', the American papaw, pawpaw, paw paw, or paw-paw, among many regional names, is a small deciduous tree native to the eastern United States and Canada, producing a large, yellowish-green to brown fruit. ''Asimina'' is the only temperate genus in the tropical and subtropical flowering plant family Annonaceae, and ''Asimina triloba'' has the most northern range of all. Well-known tropical fruits of different genera in family Annonaceae include the custard-apple, cherimoya, sweetsop, ylang-ylang, and soursop. The pawpaw is a patch-forming (clonal) understory tree of hardwood forests, which is found in well-drained, deep, fertile bottomland and also hilly upland habitat. It has large, simple leaves with drip tips, more characteristic of plants in tropical rainforests than within this species' temperate range. Pawpaw fruits are the largest edible fruit indigenous to the United States (not counting gourds, which are typically considered vegetables rather than frui ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gourd
Gourds include the fruits of some flowering plant species in the family Cucurbitaceae, particularly ''Cucurbita'' and ''Lagenaria''. The term refers to a number of species and subspecies, many with hard shells, and some without. One of the earliest domesticated types of plants, subspecies of the bottle gourd, ''Lagenaria siceraria'', have been discovered in archaeological sites dating from as early as 13,000 BCE. Gourds have had numerous uses throughout history, including as tools, musical instruments, objects of art, film, and food. Terminology ''Gourd'' is occasionally used to describe crop plants in the family Cucurbitaceae, like pumpkins, cucumbers, squash, luffa, and melons. More specifically, ''gourd'' refers to the fruits of plants in the two Cucurbitaceae genera ''Lagenaria'' and ''Cucurbita'', or also to their hollow, dried-out shell. There are many different gourds worldwide. The main plants referred to as gourds include several species from the genus ''Cucurbita'' ...

Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ripe Fruit Of Asimina Triloba
Réseaux IP Européens (RIPE, French for "European IP Networks") is a forum open to all parties with an interest in the technical development of the Internet. The RIPE community's objective is to ensure that the administrative and technical coordination necessary to maintain and develop the Internet continues. It is not a standards body like the Internet Engineering Task Force (IETF) and does not deal with domain names like ICANN. RIPE is not a legal entity and has no formal membership. This means that anybody who is interested in the work of RIPE can participate through mailing lists and by attending meetings. RIPE has a chair to keep an eye on work between RIPE meetings and to act as its external liaison. Rob Blokzijl, who was instrumental in the formation of RIPE, was the initial chair and remained in that position until 2014, when he appointed Hans Petter Holen as his successor. The RIPE community interacts via RIPE Mailing Lists, RIPE Working Groups, and RIPE Meetings. Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Annonacin
Annonacin is a chemical compound with toxic effects, especially in the nervous system, found in some fruits such as the paw paw, custard apples, soursop, and others from the family ''Annonaceae''. It is a member of the class of compounds known as acetogenins. Annonacin-containing fruit products are regularly consumed throughout the West Indies for their traditional medicine uses. Traditional medicine Historically, plants and fruits of Annonaceae (particularly '' Annona muricata'' and ''Annona squamosa'') have been consumed in various forms throughout the West Indies, usually as hot water extracts of leaves.Ross, I. A. (2003). Annona muricata L. Medicinal Plants of the World, Vol. 1: Chemical Constituents, Traditional and Modern Medicinal Uses,1, 133-142. These annonacin-containing herbal teas are thought to be useful in folk medicine. On the Caribbean island of Guadeloupe, such teas are consumed mainly for their sedative qualities.

Neurotoxin
Neurotoxins are toxins that are destructive to nerve tissue (causing neurotoxicity). Neurotoxins are an extensive class of exogenous chemical neurological insultsSpencer 2000 that can adversely affect function in both developing and mature nervous tissue.Olney 2002 The term can also be used to classify endogenous compounds, which, when abnormally contacted, can prove neurologically toxic. Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol (drinking alcohol), glutamate,Choi 1987 nitric oxide, botulinum toxin (e.g. Botox), tetanus toxin,Simpson 1986 and tetrodotoxin. Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive concentrations. Neurotoxins inhibit neuron control over ion concentrations across the cell membrane, or com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent ...

Pineapple
The pineapple (''Ananas comosus'') is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae. The pineapple is indigenous to South America, where it has been cultivated for many centuries. The introduction of the pineapple to Europe in the 17th century made it a significant cultural icon of luxury. Since the 1820s, pineapple has been commercially grown in greenhouses and many tropical plantations. Pineapples grow as a small shrub; the individual flowers of the unpollinated plant fuse to form a multiple fruit. The plant is normally propagated from the offset produced at the top of the fruit, or from a side shoot, and typically matures within a year. Botany The pineapple is a herbaceous perennial, which grows to tall, although sometimes it can be taller. The plant has a short, stocky stem with tough, waxy leaves. When creating its fruit, it usually produces up to 200 flowers, although some large-fruited cultivars can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mango
A mango is an edible stone fruit produced by the tropical tree ''Mangifera indica''. It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. ''M. indica'' has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus ''Mangifera'' also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion. Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh. Etymology The English word ''mango'' (plural "mangoes" or "mangos") originated in the 16th century from the Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banana
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus ''Musa''. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless ( parthenocarp) bananas come from two wild species – ''Musa acuminata'' and ''Musa balbisiana''. The scientific names of most cultivated bananas are ''Musa acuminata'', ''Musa balbisiana'', and ''Musa'' × ''paradisiaca'' for the hybrid ''Musa acuminata'' × ''M. balbisiana'', depending on their genomic constitution. The old scientific name for this hybrid, ''Musa sapientum'', is no longer used. ''Musa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
