Anders Sánchez Barfod
Anders is a male name in Scandinavian languages and Fering North Frisian, an equivalent of the Greek Andreas ("manly") and the English Andrew. It originated from Andres via metathesis. In Sweden, Anders has been one of the most common names for many centuries, earliest attested in 1378. It was common for priests and farmers during medieval times. According to Statistics Sweden, as of 31 December 2002 it ranks 4th among the male names. The great frequency of this name at the point in time (around 1900) when patronymics were converted into family names is the reason why 1 out of every 30 Swedes today is called Andersson. The name day of Anders in the Scandinavian calendar is 30 November, and in the old peasant superstition that day was important for determining what the Christmas weather would be. If it was very cold on 30 November there would be much sleet on Christmas (and vice versa). In Denmark Donald Duck's name is ''Anders And''. The Fering name Anders may have been bor ...

Phytelephas
''Phytelephas'' is a genus containing six known species of dioecious palms (family Arecaceae), occurring from southern Panama along the Andes to Ecuador, Bolivia, Colombia, northwestern Brazil, and Peru. They are commonly known as ivory palms, ivory-nut palms or tagua palms; the scientific name ''Phytelephas'' means "plant ivory". This and the first two of the common names refer to the very hard white endosperm of their seeds (tagua nuts or jarina seeds), which resembles elephant ivory. They are medium-sized to tall palms reaching up to 20 m tall, with pinnate leaves. The "nut" is covered with pericarp, which gets removed by animals. The kernel is covered with a brown, flaky skin and shaped like a small avocado, roughly 4–8 cm in diameter. Uses Given trade restrictions in elephant ivory as well as animal welfare concerns, ivory palm endosperm is often used as a substitute for elephant ivory today, and traded under the names vegetable ivory, palm ivory, ''marfim-vegetal' ...

Ovulate
Ovulation is the release of eggs from the ovaries. In women, this event occurs when the ovarian follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm. In addition, the uterine lining (endometrium) is thickened to be able to receive a fertilized egg. If no conception occurs, the uterine lining as well as the egg will be shed during menstruation. Process Ovulation occurs about midway through the menstrual cycle, after the follicular phase. The days in which a person is most fertile can be calculated based on the date of the last menstrual period and the length of a typical menstrual cycle. The few days surrounding ovulation (from approximately days 10 to 18 of a 28-day cycle), constitute the most fertile phase. The time from the beginning of the last menstrual period (LMP) until ovulation is, on average, 14.6 days, but with substantial variation among females and between ...

Vegetable Ivory
Vegetable ivory or tagua nut is a product made from the very hard white endosperm of the seeds of certain palm trees. Vegetable ivory is named for its resemblance to animal ivory. Species in the genus ''Phytelephas'' (literally "elephant plant"), native to South America, are the most important sources of vegetable ivory. The seeds of the Caroline ivory-nut palm from the Caroline Islands, natangura palm from Solomon Islands and Vanuatu, and the real fan palm, from Sub-Saharan Africa, are also used to produce vegetable ivory. A tagua palm can take up to 15 years to mature. But once it gets to this stage it can go on producing vegetable ivory for up to 100 years. In any given year a tagua palm can produce up to 20 pounds of vegetable ivory. The material is called ''corozo'' or ''corosso'' when used in buttons. Species Some species from which vegetable ivory is harvested are: *''Phytelephas macrocarpa'' (mainly in Peru and Bolivia) *''Phytelephas aequatorialis'' (mainly in E ...

Phytelephas Aequatorialis
The palm tree ''Phytelephas aequatorialis'', commonly known as Ecuadorian ivory palm, is the main source of Ecuadorean vegetable ivory or tagua, a botanical alternative to ivory. It is found in the tropical rainforests of the western Andean slopes of Ecuador. It has a woody trunk which can grow to 20 m in height and very long pinnate leaves. Description The plants are dioecious, with the female individuals bearing large brown conical fruits, each approximately the size of a grapefruit (but occasionally up to fourteen inches (35 centimeters) in diameter and weighing up to 42 pounds (19 kilograms) and covered in a horned husk, containing usually four seeds. Immature seeds contain sweet edible pulp. Mature seeds are harder than wood and are encased in a bonelike shell. The endosperm is a white hemicellulose material that is so hard it can be polished and carved like ivory. The male flowers are in a catkin, and each flower has as many as 1,000 stamens,Little and Dixon Arboles Communes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, Pierre. 1957 ...

Vicariance
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
