Scaptotrigona Mexicana
''Scaptotrigona mexicana'' is a species of stingless bee that lives throughout Mexico and is part of the Meliponini tribe. This species is sometimes termed "Pisil Nekmej" and is extensively studied for its medicinal purposes. This species is considered common and abundant throughout Mexico and it has been noted to thrive in tropical environments. Taxonomy and phylogeny ''S. mexicana'' is part of the family Apidae and is in the tribe Meliponini. This species was named by Félix Édouard Guérin-Méneville in 1845. Description and identification ''S. mexicana'' is composed of a queen, female workers, and males within each colony. The males of this species are haploid and the queens single mate, resulting in reproductive colonies throughout the year. This species has been noted to be stingless and have strong jaws with which to bite. Queen characteristics The queen is noted to focus on single mating, and colonies are often formed within areas where virgin queens are thought to ...

Félix Édouard Guérin-Méneville
Félix Édouard Guérin-Méneville, also known as F. E. Guerin, (12 October 1799, in Toulon – 26 January 1874, in Paris) was a French entomologist. Life and work Guérin-Méneville changed his surname from Guérin in 1836. He was the author of the illustrated work ''Iconographie du Règne Animal de G. Cuvier 1829–1844'', a complement to the work of the zoologists Georges Cuvier and Pierre André Latreille, ''Le Règne Animal'', which illustrated only a selection of the animals covered. Cuvier was delighted with the work, saying that it would be very useful to readers, and that the illustrations were "as accurate as they were elegant". He also introduced silkworms to France, so they could be bred for the production of silk. Guérin-Méneville founded several journals: ''Magasin de zoologie, d’anatomie comparée et de paléontologie'' (1830), ''Revue zoologique par la Société cuviérienne'' (1838), ''Revue et Magasin de zoologie pure et appliquée'' (1849), and ''Revue de ...

CIA Map Of Central America
The Central Intelligence Agency (CIA ), known informally as the Agency and historically as the Company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and performing covert actions. As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States. President Harry S. Truman had created the Central Intelligence Group under the direction of a Director of Central Intelligence by presidential directive on January 22, 1946, and this group was transformed into the Central Intelligence Agency by implementation of the National Security Act of 1947.

Hymenoptera Of North America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medicines ...

Piper (plant)
''Piper'', the pepper plants or pepper vines, is an economically and ecologically important genus in the family Piperaceae. It contains about 1,000-2,000 species of shrubs, herbs, and lianas, many of which are dominant species in their native habitat. The diversification of this taxon is of interest to understanding the evolution of plants. Pepper plants belong to the magnoliids, which are angiosperms but neither monocots nor eudicots. Their family, Piperaceae, is most closely related to the lizardtail family (Saururaceae), which in fact generally look like smaller, more delicate and amphibious pepper plants. Both families have characteristic tail-shaped inflorescences covered in tiny flowers. A somewhat less close relative is the pipevine family (Aristolochiaceae). A well-known and very close relative – being also part of the Piperaceae – are the radiator plants of the genus ''Peperomia''. The scientific name ''Piper'' and the common name "pepper" are derived from the San ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miconia
''Miconia'' is a genus of flowering plants in the glory bush family, Melastomataceae, native to warm temperate to tropical regions of the Americas. The species are mostly shrubs and small to medium-sized trees up to 15 m tall. The generic name honours Catalan physician and botanist Francesc Micó. Some species are known by the common name johnnyberry. Many species are threatened by habitat destruction in their native range, and some are feared to be on the brink of extinction. On the other hand, '' M. calvescens'' is a contributing factor in the decline and maybe even extinction of other plants: it has become a highly invasive weed on a number of Pacific Islands where it was introduced, including Hawaii and Tahiti. It is often referred to as the "purple plague" or the "green cancer" in reference to its habit of overgrowing native ecosystems, and its leaves which are bright green above and bright purple below. ''Miconia'' fruit are a favorite food of many birds (invasive ''M. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coffea Arabica
''Coffea arabica'' (), also known as the Arabic coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is currently the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean ('' C. canephora'') makes up most of the remaining coffee production. Arabica coffee originates from and was first cultivated in Yemen, and documented by the 12th century. ''Coffea arabica'' is called () in Arabic, borrowed from the Amharic "Buna". Taxonomy ''Coffea arabica'' was first described scientifically by Antoine de Jussieu, who named it ''Jasminum arabicum'' after studying a specimen from the Botanic Gardens of Amsterdam. Linnaeus placed it in its own genus ''Coffea'' in 1737. ''Coffea arabica'' is the only polyploid species of the genus ''Coffea,'' as it carries 4 copies of the 11 chromosom ...

Pimenta Dioica
Allspice, also known as Jamaica pepper, myrtle pepper, pimenta, or pimento, is the dried unripe berry of ''Pimenta dioica'', a midcanopy tree native to the Greater Antilles, southern Mexico, and Central America, now cultivated in many warm parts of the world. The name ''allspice'' was coined as early as 1621 by the English, who valued it as a spice that combined the flavours of cinnamon, nutmeg, and clove. Several unrelated fragrant shrubs are called "Carolina allspice" ('' Calycanthus floridus''), "Japanese allspice" (''Chimonanthus praecox''), or "wild allspice" ('' Lindera benzoin''). Production Allspice is the dried fruit of the ''Pimenta dioica'' plant. The fruits are picked when green and unripe, and are traditionally dried in the sun. When dry, they are brown and resemble large, smooth peppercorns. Fresh leaves are similar in texture to bay leaves and similarly used in cooking. Leaves and wood are often used for smoking meats where allspice is a local crop. Care ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eusociality
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the ...
