Valdivian Temperate Rain Forests
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and Argentina. It is part of the Neotropical realm. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common. Setting Temperate rain forests comprise a relatively narrow coastal strip between the Pacific Ocean to the west, and the southern Andes Mountains to the east, from roughly 37° to 48° south latitude. North of 42°, the Chilean coastal range runs along the coast, and the north–south running Chilean Central Valley lies between the coastal range and the Andes. South of 42°, the coast range continues as a chain of offshore islands, including Chiloé Island and the Chonos Archipelago, while the "Central Valley" is submerged and continues as the G ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Bosque De Olivillo En Punta Curinanco
A bosque ( ) is a type of gallery forest habitat found along the riparian flood plains of stream and river banks in the southwestern United States. It derives its name from the Spanish word for 'woodlands'. Setting In the predominantly arid or semi-arid southwestern United States, a bosque is an oasis-like ribbon of green vegetation, often canopied, that only exists near rivers, streams, or other water courses. The most notable bosque is the -long ecosystem along the valley of the middle Rio Grande in New Mexico that extends from Santa Fe south to El Paso, Texas. One of the most famous and ecologically intact sections of the bosque is included in the Bosque del Apache National Wildlife Refuge. Flora and fauna Common trees in the bosque habitat include mesquite, cottonwood, desert willow, and desert olive. Because there is often only a single canopy layer and because the tree species found in the bosque are generally deciduous, a wide variety of shrubs, grasses, and ...

Termas Geometricas
Terma (; "hidden treasure") are various forms of hidden teachings that are key to Vajrayana and Tibetan Buddhist and Bon spiritual traditions. In the Vajrayana Nyingma school tradition, two lineages occur: an oral ''kama'' lineage and a revealed ''terma'' lineage. Tradition holds that ''terma'' teachings were originally esoterically hidden by eighth-century Vajrayana masters Padmasambhava and Yeshe Tsogyal, to be discovered at auspicious times by treasure revealers known as tertöns. As such, terma represent a tradition of continuous revelation in Vajrayana and Tibetan Buddhism. Tradition Tradition holds that terma may be a physical object such as a text or ritual implement that is buried in the ground, hidden in a rock or crystal, secreted in a herb, or a tree, hidden in water, or hidden in the sky or in space. Though a literal understanding of ''terma'' is "hidden treasure", and sometimes refers to objects that are hidden away, the teachings associated should be understood as bei ...

Fjord
In physical geography, a fjord or fiord () is a long, narrow inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Alaska, Antarctica, British Columbia, Chile, Denmark, Germany, Greenland, the Faroe Islands, Iceland, Ireland, Kamchatka, the Kerguelen Islands, Labrador, Newfoundland, New Zealand, Norway, Novaya Zemlya, Nunavut, Quebec, the Patagonia region of Argentina and Chile, Russia, South Georgia Island, Tasmania, United Kingdom, and Washington state. Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjords wh ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Patagonian Ice Sheet
upright=1.4, Map showing the extent of the Patagonian Ice Sheet in the Strait of Magellan area during the last glacial period. Selected modern settlements are shown with yellow dots. Sea level was much lower than shown here. The Patagonian Ice Sheet was a large elongated and narrow ice sheet centered in the southern Andes that existed during the Llanquihue glaciation. The ice sheet covered all of Chile south of Puerto Montt plus the western fringes of Argentine Patagonia. The ice sheet extended beyond the crest of the Andes into Argentina, but because of the dryness of the climate it did not reach beyond present-day lakes such as the Yagagtoo, Musters, and Colhue Huapi. At its peak (about 18,000-17,500 years ago), the Patagonian Ice Sheet covered about 480,000 km² of land with an estimated ice-volume of more than 500,000 km³,Hulton, N.R.J., R.S. Purvesa, R.D.

Gulf Of Corcovado
Gulf of Corcovado () is a large body of water separating the Chiloé Island from the mainland of Chile. Geologically, it is a forearc basin that has been carved out by Quaternary glaciers. Most of the islands of Chiloé Archipelago are located in the gulf. The area is next to the Chiloé National Park. In colonial times the Gulf of Corcovado was a major obstacle that prevented major contact between the Spanish settlers in Chiloé Archipelago and the southern Chonos living in the archipelagoes of Guaitecas and ristian ghost Archipelagoristian ghost]. In the early 17th-century, Jesuits rounded the gulf instead of crossing it when traveling south by dalcas from their base in Castro.

Chonos Archipelago
The Chonos Archipelago is a series of low, mountainous, elongated islands with deep bays, traces of a submerged Chilean Coast Range. Most of the islands are forested with little or no human settlement. The deep Moraleda Channel separates the islands of the Chonos Archipelago from the mainland of Chile and from Magdalena Island. The largest islands are Melchor Island, Benjamin Island, Traiguen Island, Riveros Island, Cuptana Island, James Island, Victoria Island, Simpson Island, Level Island, Luz Island. Far out in the Pacific is Guamblin Island with the Isla Guamblin National Park. The National park comprises about 106 km². Blue whales can often be seen here. Some groups of islands are grouped into minor archipelagoes such as the Guaitecas Archipelago. The Guaitecas Archipelago has its own municipality and possesses the only settlement in the archipelago, Melinka. All islands are part of the Aisén Region. Chonos Archipelago was mapped in the 18th and 19th centurie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiloé Island
Chiloé Island ( es, Isla de Chiloé, , ) also known as Greater Island of Chiloé (''Isla Grande de Chiloé''), is the largest island of the Chiloé Archipelago off the west coast of Chile, in the Pacific Ocean. The island is located in southern Chile, in the Los Lagos Region. Of roughly rectangular shape, the southwestern half of the island is a wilderness of contiguous forests and swamps. Mountains in the island form a belt running from the northwestern to the southeastern corner of the island. Cordillera del Piuchén make up the northern mountains and the more subdued Cordillera de Pirulil gathers the southern mountains. The landscape of the northeastern sectors of Chiloé Island is dominated by rolling hills with a mosaic of pastures, forests and cultivated fields. While the western shores are rocky and relatively straight, the eastern and northern shores contain many inlets, bays and peninsulas, and it is here where all towns and cities lie. Geographically, the bulk of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilean Central Valley
The Central Valley ( es, Valle Central), Intermediate Depression, or Longitudinal Valley is the depression between the Chilean Coastal Range and the Andes Mountains. The Chilean Central Valley extends from the border with Peru to Puerto Montt in southern Chile, with a notable interruption at Norte Chico (27°20'–33°00' S). South of Puerto Montt the valley has a continuation as a series of marine basins up to the isthmus of Ofqui. Some of Chile's most populous cities lie within the valley including Santiago, Temuco, Rancagua, Talca and Chillán. Northern section (18°30'–27°20' S) In northernmost Chile the central valley is made up of the Pampitas, a series of small flats dissected by deep valleys.Börger, p. 40. Immediately south of the Pampitas, in Tarapacá Region and northern of Antofagasta Region, the Central Valley is known as Pampa del Tamarugal.Börger, p. 41.Brüggen, p. 6.
