Larrea Tridentata, Creosote Bush
''Larrea'' is a genus of flowering plants in the caltrop family, Zygophyllaceae. It contains five species of evergreen shrubs that are native to the Americas. The generic name honours Bishop Juan Antonio Hernández Pérez de Larrea, a patron of science."Larrea" is itself a Basque surname, where ''larrea'' stands for a village in Álava (Spain), ultimatelmeaning 'meadow'(plus article -a). South American members of this genus are known as ''jarillas'' and can produce fertile interspecific hybrids. One of the more notable species is the creosote bush ('' L. tridentata'') of the southwestern United States and northwestern Mexico. The King Clone ring in the Mojave Desert is a creosote bush clonal colony estimated to be about 11,700 years old.

Basque Surname
Basque surnames are surnames with Basque-language origins or a long, identifiable tradition in the Basque Country (greater region), Basque Country. They can be divided into two main types, patronymic and non-patronymic. The patronymics such as Aluariz (probably Alvariz, child of Alvar, as in the past 'u' and 'v' were indistinguishable in writing), Obecoz or Garcez are amongst the most ancient, going as far back as the 10th century. The Basque monarchy, including the first king of Pamplona, Íñigo Arista of Pamplona, or Eneko Aritza, were the first to use this type of surname. Patronymics are by far the most common surnames in the whole of the Basque Autonomous Community and Navarre. The non-patronymic surnames are often toponymic ones that refer to the family's ''etxea'', the historically all important family home. When a farm (baserri) was rented to another family, often the new tenants were known locally by the farm name rather than by their officially registered surname. They ...

Flora Of The Americas
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'' for purposes of specificity. 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 ...

Zygophyllales Genera
The Zygophyllales are an order of dicotyledonous plants, comprising the following two families: * Family Zygophyllaceae * Family Krameriaceae According to the Angiosperm Phylogeny Group (APG II) both families are unplaced to order, but nevertheless included in the Eurosids I. The APG III system of 2009, however, recognized this order. Even if the monogeneric family Krameriaceae shares few common traits with the family Zygophyllaceae, researchers see little advantage in keeping it as a separate family (e.g. Sheahan and Chase). The name Zygophyllales can be used if one finds it appropriate to place both families into an order. The order remains unchanged in the APG IV system. Under the Cronquist system, the Zygophyllaceae were included within the Sapindales, and the Krameriaceae within the Polygalales Fabales is an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Darwiniana
''Darwiniana: Essays and Reviews Pertaining to Darwinism'' is a collection of essays by botanist Asa Gray, first published in 1876. These widely read essays both defended the theory of evolution from the standpoint of botany and sought reconciliation with theology by arguing theistic evolution — that natural selection is not inconsistent with Christianity Christianity is an Abrahamic monotheistic religion, which states that Jesus in Christianity, Jesus is the Son of God (Christianity), Son of God and Resurrection of Jesus, rose from the dead after his Crucifixion of Jesus, crucifixion, whose .... Gray considered natural selection to be the cause of new species, which was itself caused by some inherent power imparted in the beginning by Godhead.

Clonal Colony
A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet. In fungi, "individuals" typically refers to the visible fruiting bodies or mushrooms that develop from a common mycelium which, although spread over a large area, is otherwise hidden in the soil. Clonal colonies are common in many plant species. Although many plants reproduce sexually through the production of seed, reproduction occurs by underground stolons or rhizomes in some plants. Above ground, these plants most often appear to be distinct individuals, but underground they remain interconnected and are all clones of the same plant. However, it is not always easy to recognize a clonal colony especially if it spreads underground and is also sexually reproducing. Methods of establishment With ...

Mojave Desert
The Mojave Desert (; ; ) is a desert in the rain shadow of the southern Sierra Nevada mountains and Transverse Ranges in the Southwestern United States. Named for the Indigenous peoples of the Americas, indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah. The Mojave Desert, together with the Sonoran Desert, Sonoran, Chihuahuan Desert, Chihuahuan, and Great Basin Desert, Great Basin deserts, form a larger List of North American deserts, North American desert. Of these, the Mojave is the smallest and driest. It displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between .

King Clone
King Clone is thought to be the oldest creosote bush ring in the Mojave Desert. The ring is estimated to be 11,700 years old, making it one of the oldest living organisms on Earth. This single clonal colony plant of ''Larrea tridentata'' reaches up to in diameter, with an average diameter of . Geography The King Clone ring is on restricted-access land in the central Mojave Desert, near the towns of Lucerne Valley and Landers. It is in the Creosote Rings Preserve of the Lucerne Valley and Johnson Valley. Dating methodology King Clone was identified and the age estimated by Frank Vasek, a professor at the University of California, Riverside. After Vasek hypothesized that the creosote ring was, in fact, one organism, Leonel da Silveira Lobo O'Reilly Sternberg (then a graduate student working in Vasek's lab), documented that plants within a ring had more similar characteristics than those from other plant clusters. Vasek then used two methods to estimate the age of the ring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...
