Zea Nicaraguensis
''Zea nicaraguensis'' is an annual, true grass species in the genus '' Zea''. It is considered to be phenotypically the most distinctive, as well as the most threatened teosinte. This teosinte thrives in flooded conditions along 200 m of a coastal estuarine river in northwest Nicaragua at the Reserva Natural de Apacunca. Virtually all populations of teosinte are either threatened or endangered with ''Z. nicaraguensis'' being the most endangered, it survives as about 6000 plants in an area of 200 x 150 m. The Mexican and Nicaraguan governments have taken action in recent years to protect wild teosinte populations, using both ''in situ'' and ''ex situ'' conservation methods. Currently, a large amount of scientific interest exists in conferring beneficial teosinte traits, such as insect resistance, perennialism, and flood tolerance, to cultivated maize lines, although this is very difficult due to linked deleterious teosinte traits.

Hugh Iltis
Hugh Iltis (April 7, 1925 – December 19, 2016) was a professor of botany and director of the herbarium at the University of Wisconsin–Madison. While he is most noted as a scientist for his role in the discovery of perennial teosinte (''Zea diploperennis''), a wild diploid relative of modern maize (''Zea mays''), he is also remembered as an outspoken environmental conservationist. Life and work He was born Hugo Hellmut Iltis to Anni (née Liebscher) and Hugo Iltis, a botanist and geneticist who was a life sciences teacher at the German-language gymnasium of Brünn (Brno). His father was also the first biographer of Gregor Mendel and a vocal opponent of Nazi "racial science". In the fall of 1938, the Iltis family was granted visas to enter the United States thanks to the intercession of the Emergency Committee in Aid of Displaced Foreign Scholars, along with affidavits of endorsement from Albert Einstein and Franz Boas. In January 1939, when Hitler's military was preparin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bruce F
The English language name Bruce arrived in Scotland with the Normans, from the place name Brix, Manche in Normandy, France, meaning "the willowlands". Initially promulgated via the descendants of king Robert the Bruce (1274−1329), it has been a Scottish surname since medieval times; it is now a common given name. The variant ''Lebrix'' and ''Le Brix'' are French variations of the surname.

Zea (plant)
''Zea'' is a genus of flowering plants in the grass family. The best-known species is ''Z. mays'' (variously called maize, corn, or Indian corn), one of the most important crops for human societies throughout much of the world. The four wild species are commonly known as teosintes and are native to Mesoamerica. Etymology ''Zea'' is derived from the Greek name () for another cereal grain (possibly spelt).Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 411 Recognized species The five accepted species names in the genus are: ''Zea mays'' is further divided into four subspecies: ''Z. m. huehuetenangensis'', ''Z. m. mexicana'', '' Z. m. parviglumis'' (Balsas teosinte, the ancestor of maize), and ''Z. m. mays''. The first three subspecies are teosintes; the last is maize, or corn, the only domesticated taxon in the genus ''Zea''. The genus is divided into two sections: ''Luxuriantes'', with ''Z. diploperennis'', ''Z. luxur ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Grasses Of North America
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, prim ...

Flora Of Nicaragua
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurma ...
