Taitao Peninsula
The Taitao Peninsula ( Spanish: ''Península de Taitao'') is a westward-facing landmass on the south-central Pacific west coast of Chile. The peninsula is connected to the mainland via the narrow Isthmus of Ofqui, over which tribal peoples and early missionaries often traveled to avoid navigating the peninsula's treacherous waters, carrying their boats and belongings overland between the Moraleda Channel and Gulf of Penas. spelled "Taytao" The Taitao Peninsula is situated in the Aysén del General Carlos Ibáñez del Campo Region, and part of the landmass is located inside the boundaries of Laguna San Rafael National Park. The Presidente Ríos Lake, with a surface area of , lies in the center of the peninsula. A southward-incurving projection of its outer shoreline is known as Tres Montes peninsula, the most southerly point of the cape of the same name. Spanish explorers and Jesuits that sailed south from Chiloé Archipelago in the 17th and 18th centuries regularly avoided r ...

Martín Olleta
Martín Olleta was a Chono chieftain who was an important broker between Spanish authorities in Chiloé Archipelago and indigenous people of the fjords and channels of Patagonia. He is known for rescuing the survivors of the wreck of in 1742. He was identified as chieftain by the British and referred to as "gobernadorcillo de dicha nación chonos" ("little governor of the Chono nation") by the Spanish governor of Chiloé Victoriano Martínez de Tineo. He used a rod with a silver handle as symbol of authority. Rescue of HMS ''Wager'' survivors Olleta led a party of indigenous Chono that visited Captain Cheap's stranded group in Wager Island, Guayaneco Archipelago. This happened fifteen days after a group of British sailors returned to Wager Island after failing to round Taitao Peninsula with an improvised barge. The Spanish language proficiency of the Chonos was enough to communicate with the Spanish-speaking surgeon of the British party. After some negotiation, the Chono agr ...

Understory
In forestry and ecology, understory (American English), or understorey (English in the Commonwealth of Nations, Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the Canopy (biology), 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 tolerance, 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 Cornus (genus), dogwood are understory specialists. In Temperate broadleaf and mixed forest, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Rafael Lake
San Rafael Lake is an arc-shaped coastal lake located in the Aysén del General Carlos Ibáñez del Campo Region of Chile, within the national park that bears its name. To the north the lagoon is connected to the Moraleda Channel, to the south lies the Ofqui Isthmus. To the west and east lie the Taitao Peninsula and the Northern Patagonian Ice Field respectively. The lake was formed by the retreat of the San Rafael Glacier in the Northern Patagonian Ice Field. Today it is a popular tourism destination, and ships sail from Puerto Chacabuco, Puyuhuapi and Puerto Montt to the lagoon nearly every day to see the ice falling from the glacier into the lagoon. Cruises pass by this area. The lake was visited by the Antonio de Vea expedition in December 1675. The expedition entered San Rafael Lake taking note of its windy conditions, the San Rafael Glacier and the swampy shores in the south that make up the Isthmus of Ofqui. Antonio de Vea entered San Rafael Lake through Río Témpa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oreobolus Obtusangulus
''Oreobolus obtusangulus'' is a thick cushion-forming, grass-like flowering plant species in the family Cyperaceae. It is native to South America.

Donatia Fascicularis
''Donatia fascicularis'' is a species of cushion plant in the family Donatiaceae and is closely related to species in the family Stylidiaceae. It is found in the alpine and subalpine regions of western Patagonia and Tierra del Fuego. It is the type species of the genus ''Donatia'' J.R. Forst. & G. Forst. Although first collected in 1769 during the first voyage of James Cook, anpainted at that timeby the on-board artist Sydney Parkinson, the genus and species were not validly published until 1776, by Johann Reinhold Forster and his son Georg, following the second voyage. In Chile ''Donatia fascicularis'' is, together with '' Astelia pumila'', dominant in the cushion bogs that exists in areas exposed to the Pacific coast. As such it is not usually found together with ''Sphagnum ''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat).

Cushion Plant
A cushion plant is a compact, low-growing, mat-forming plant that is found in alpine, subalpine, arctic, or subarctic environments around the world. The term "cushion" is usually applied to woody plants that grow as spreading mats, are limited in height above the ground (a few inches at most), have relatively large and deep tap roots, and have life histories adapted to slow growth in a nutrient-poor environment with delayed reproductivity and reproductive cycle adaptations. The plant form is an example of parallel or convergent evolution with species from many different plant families on different continents converging on the same evolutionary adaptations to endure the harsh environmental conditions.Went, F. W. (1971). Parallel evolution. ''Taxon'', 20(2/3): 197-226. Description Cushion plants form large, low-growing mats that can grow up to in diameter. The typical form is a compact mass of closely spaced stems with minimal apical dominance that terminate in individual ros ...

Peatland
A peatland is a type of wetland whose soils consist of Soil organic matter, organic matter from decaying plants, forming layers of peat. Peatlands arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to Waterlogging (agriculture), water-logging and subsequent anoxic waters, anoxia. Peatlands are unusual landforms that derive mostly from biological rather than physical processes, and can take on characteristic shapes and surface patterning. The formation of peatlands is primarily controlled by climatic conditions such as precipitation and temperature, although terrain relief is a major factor as waterlogging occurs more easily on flatter ground and in basins. Peat formation typically initiates as a paludification of a mineral soil forests, terrestrialisation of lakes, or primary peat formation on bare soils on previously glaciated areas. A peatland that is actively forming peat is called a ''mire''. All types of mires share the common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
