Cornelis Christiaan Berg
Cornelis Christiaan (Cees) Berg (1934–2012) was a Dutch botanist known for his work on the plant family Moraceae. Early life and education Berg was born on 7 February 1934 in Bandung, Indonesia, then part of the Dutch East Indies, and later moved to Sumatra, near Medan. During World War II, his father was conscripted, and died during the Japanese conquest. Berg was interned with his mother and brothers, and moved to a men's camp at the age of 10. Berg, his mother and siblings, all survived their internment, but his mother died of starvation shortly after. After the war, the orphaned siblings were raised with foster families in the Netherlands. He got his education in the Netherlands, where he went to the school of horticulture at Breda. Career From 1959 to 1966 he worked at some colleges and from 1960 to 1986 held several positions at the University of Utrecht. Later on he graduated from that university in 1962 and 1964 respectively with a Ph.D. in 1973. A year before he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erik Albert Mennega
Erik Albert Mennega (6 January 1923 – 27 January 1998) was a Dutch botanist, plant taxonomist, and author. Biography Mennega studied biology at Utrecht University, receiving his degree in 1947. He was then hired as a taxonomist at the Utrecht University Botanic Gardens. He spent much of his time identifying botanical collections at the original garden in Baarn, as well as identifying at documenting species at the Von Gimborn Arboretum. He remained at the gardens until his retirement in 1984.Zijlstra, G. (1998). Erik A. Mennega (1923-1998). Taxon, 47(4), 974-975. Retrieved from http://www.jstor.org/stable/1224228 In 1988, Frans Stafleu and Richard Sumner Cowan published the second edition of ''Taxonomic Literature: A Selective Guide to Botanical Publications and Collections, with Dates, Commentaries, and Types''. After Cowan left the project, Stafleu began collaborating with Mennega on a supplement series. The two wrote and published six volumes between 1992 and 2000, the last tw ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Peperomia
''Peperomia'' is one of the two large genera of the family Piperaceae. It is estimated that there are at least over 1,000 species, occurring in all tropical and subtropical regions of the world. They are concentrated in northern South America and Central America, but are also found in Africa, southern Asia, and Oceania. The exact number is difficult to tell as some plants have been recorded several times with different names (c. 3,000 names have been used in publications) and new species continue to be discovered. Peperomias have adapted to many different environments and their appearance varies greatly. Some are epiphytes (growing on other plants) or lithophytes (growing on rock or in rock crevices), and many are xerophytes (drought-tolerant) either with thick succulent structures or with underground tubers (geophytes). Most species are compact perennial shrubs or vines. The genus name ''Peperomia'' was coined by Spanish botanists Ruiz López and Pavón Jiménez in 1794 aft ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Piperaceae
The Piperaceae (), also known as the pepper family, are a large family of flowering plants. The group contains roughly 3,600 currently accepted species in 5 genera. The vast majority of species can be found within the two main genera: ''Piper'' (2,171 species) and ''Peperomia'' (over 1,000 species). Members of the Piperaceae may be small trees, shrubs, or herbs. The distribution of this group is best described as pantropical. The best-known species, ''Piper nigrum'', yields most peppercorns that are used as spices, including black pepper, although its relatives in the family include many other spices. Etymology The name Piperaceae is likely to be derived from the Sanskrit term ''pippali'', sa, पिप्पली, which was used to describe long peppers (like those of ''Piper longum''). Taxonomy The APG III system of 2009 recognizes this family, and assigns it to the order Piperales in the unranked clade magnoliids. The family consists of five genera: ''Piper'', ''Peperom ...

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
