Drimys Winteri
''Drimys winteri'', also known as Winter's bark, foye and canelo, is a slender species of tree in the family Winteraceae, growing up to tall. It is native to the Magellanic and Valdivian temperate forests of Chile and Argentina, where it is a dominant tree in the coastal evergreen forests. It is found below between latitude 32° south and Cape Horn at latitude 56°. In its southernmost natural range it can tolerate temperatures down to . The plant is renowned for its phenotypic plasticity being able to grow in different sites from "extreme arid zones to wetlands along Chile". The tree does also grow in places with various types and degrees of competition from other plants. Description The leaves are lanceolate, glossy green above, whitish below and can measure up to . The flowers are white with a yellow center, and consist of a great number of petals and stamens. The fruit is a bluish berry. The height–diameter relation of ''D. winteri'' varies greatly.

Diameter At Breast Height
Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Tree trunks are measured at the height of an adult's breast, which is defined differently in different countries and situations. In many countries, DBH is measured at approximately above ground. Global variation and scientific precision The height can make a substantial difference to the measured diameter. In the United States, DBH is typically measured at above ground. In some countries, such as Australia, New Zealand, Burma, India, Malaysia, and South Africa, breast height diameter has historically been measured at a height of , but because of much active research into allometrics that are being applied to trees and forests, the convention of is more appropriate. Ornamental trees are usually measured at 1.5 metres above ground. Some authors have argued that the term DBH should be abolish ...

Francis Drake's Circumnavigation
Francis Drake's circumnavigation, also known as Drake's Raiding Expedition, was an important historical maritime event that took place between 15 December 1577 and 26 September 1580. The expedition was authorised by Queen Elizabeth I and consisted of five ships led by Francis Drake. Termed a 'voyage of discovery', it was in effect an ambitious covert raiding voyage and the start of England's challenge to the global domination of Spain and Portugal. Drake set off on 15 December 1577 after a delay of nearly six months. After capturing Spanish vessels and Portuguese caravels while crossing the Atlantic he became the first Englishman to navigate the Straits of Magellan. After reaching the Pacific Ocean in October 1578, he sailed up the west coast of South America. Due to losses by storms and disease, only two ships remained, one of which was the ''Golden Hind''. Drake then plundered Spanish ports and took a number of Spanish treasure ships including the rich galleon ''Nuestra Señora ...

Sir Francis Drake
Sir Francis Drake ( 1540 – 28 January 1596) was an English Exploration, explorer and privateer best known for making the Francis Drake's circumnavigation, second circumnavigation of the world in a single expedition between 1577 and 1580 (being the first English expedition to accomplish this). He is also known for participating in the early English slaving voyages of his cousin, John_Hawkins_(naval_commander), John Hawkins, and John_Lovell_(slave_trader), John Lovell. Having started as a simple seaman, in 1588 he was part of the fight against the Spanish Armada as a vice admiral. At an early age, Drake was placed into the household of a relative, William Hawkins (died c. 1554), William Hawkins, a prominent sea captain in Plymouth. In 1572, he set sail on his Francis Drake's expedition of 1572–1573, first independent mission, privateering along the Spanish Main. Drake's circumnavigation began on 15 December 1577. He crossed the Pacific Ocean, until then an area of exclusive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mapuche Religion
Mapuche religion is the traditional Native American religion of the Mapuche people. It is practiced primarily in south-central Chile and southwest Argentina. The tradition has no formal leadership or organizational structure and displays much internal variation. Mapuche theology incorporates a range of deities and spirits. One of the most prominent deities is Ngünechen, sometimes equated with the Christian God. Communal prayer ceremonies are termed ''ngillatun'' and involve the provision of offerings and animal sacrifice. Various different ritual specialists were historically active among the Mapuche, but in the 20th century many of these died out, leaving the ''machi'' as the main kind. These ''machi'' are tasked with overseeing healing and divination, tasks accomplished through their communication with spirits. Historically, the Mapuche were politically independent and prevented conquest by the Incan and Spanish Empires. In 1883 the Chilean military defeated the Mapuche and ...

Mapuche
The Mapuche ( , ) also known as Araucanians are a group of Indigenous peoples of the Americas, Indigenous inhabitants of south-central Chile and southwestern Argentina, including parts of Patagonia. The collective term refers to a wide-ranging ethnicity composed of various groups who share a common social, religious, and economic structure, as well as a common linguistic heritage as Mapudungun speakers. Their homelands once extended from Choapa River, Choapa Valley to the Chiloé Archipelago and later spread eastward to Puelmapu, a land comprising part of the Pampas, Argentine pampa and Patagonia. Today the collective group makes up over 80% of the Indigenous peoples in Chile and about 9% of the total Chilean population. The Mapuche are concentrated in the Araucanía (historic region), Araucanía region. Many have migrated from rural areas to the cities of Santiago and Buenos Aires for economic opportunities, more than 92% of the Mapuches are from Chile. The Mapuche traditional e ...

Sacred Tree
A sacred tree or holy tree is a tree which is considered to be sacred, or worthy of spiritual respect or reverence. Such trees appear throughout world history in various cultures including the ancient Hindu mythology, Greek, Celtic and Germanic mythologies and is central to the beliefs of The Church of Jesus Christ of Latter-day Saints. They also continue to hold profound meaning in contemporary culture in places like Japan (''shinboku''), Korea (''dangsan namu''), India (bodhi tree), and the Philippines, among others. Tree worship is core part of religions which include aspects of animism as core elements of their belief, which is the belief that trees, forests, rivers, mountains, etc. have a life force ('anime', i.e., ''alive''). An example of the continued importance of sacred trees in contemporary urban culture is the 700-year old camphor growing in the middle of Kayashima Station. Locals protested against moving the tree when the railway station had to be expanded, so the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relict (biology)
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group did ...

Vessel Element
A vessel element or vessel member (also called a xylem vessel) is one of the cell types found in xylem, the water conducting tissue of plants. Vessel elements are found in most angiosperms (flowering plants) and in some gymnosperms such as cycads and ''Ephedra (plant), Ephedra'', but absent in conifers. Vessel elements are the main feature distinguishing the "hardwood" of angiosperms from the "softwood" of conifers. Anatomy Xylem is the tissue in vascular plants that conducts water (and substances dissolved in it) upwards from the roots to the shoots. Two kinds of cell are involved in xylem transport: tracheids and vessel elements. Vessel elements are the building blocks of vessels, the conducting pathways that constitute the major part of the water transporting system in flowering plants. Vessels form an efficient system for transporting water (including necessary minerals) from the root to the leaves and other parts of the plant. In secondary xylem – the xylem that is prod ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
