La Yeguada
La Yeguada (also known as Chitra-Calobre) is a massive stratovolcano located in Veraguas Province, Panama, north of the Azuero Peninsula. Description De Boer et al. were the first to show that La Yeguada volcano is active and part of the extension of the Central American volcanic arc in Panama. Further detailed work on the geochemistry of the lavas from La Yeguada and other volcanoes in Panama was completed by Defant et al.Defant, M. J., Jackson, T. E., Drummond, M. S., de Boer, J. Z., Bellon, H., Feigenson, M. D., Maury, R. C., and Stewart, R.H., 1992, The geochemistry of young volcanism throughout western Panama and southeastern Costa Rica: An overview: J. Geol. Soc. Lond., v. 149, pp. 569–579. They substantiated, based on geochemistry, that the lavas were derived by subduction (calc-alkaline). Radiometric dates also showed that the volcanism falls into two groups that range from 20 million years to recent. They also showed that the youngest volcanism consists primarily of ada ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Miocene Stratovolcanoes
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. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcanoes Of Panama
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Panama
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Veraguas
Veraguas () is a province of Panama, located in the centre-west of the country. The capital is the city of Santiago de Veraguas. It is the only Panamanian province to border both the Atlantic and Pacific oceans. It covers an area of 10,587.6 km² and in 2019 it had an estimated population of 247,644. History Veraguas was originally inhabited by the Veraguas culture. Veraguas was explored by Christopher Columbus on his fourth voyage. He tried to establish the first colony in the new Spanish mainland but failed due to resistance from Indigenous peoples. Diego de Nicuesa also tried to establish a colony and failed, which made him create a colony to fight against the Indigenous population, which he named Nombre de Dios. Its capital, Santiago de Veraguas, was founded about 1636. It is said that its name comes from the indigenous word "Veracua" or "Viragua", though other theories abound. It is the only province in Panama with coastlines on both the Caribbean Sea and the Paci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cedrus
''Cedrus'', common English name cedar, is a genus of coniferous trees in the plant family Pinaceae (subfamily Abietoideae). They are native plant, native to the mountains of the western Himalayas and the Mediterranean region, occurring at altitudes of 1,500–3,200 m in the Himalayas and 1,000–2,200 m in the Mediterranean.Farjon, A. (1990). ''Pinaceae. Drawings and Descriptions of the Genera''. Koeltz Scientific Books . Description ''Cedrus'' trees can grow up to 30–40 m (occasionally 60 m) tall with spicy-resinous scented wood, thick ridged or square-cracked Bark (botany), bark, and broad, level branches. The shoots are dimorphic and are made up of long shoots, which form the framework of the branches, and short shoots, which carry most of the leaves. The leaf, leaves are evergreen and needle-like, 8–60 mm long, arranged in an open spiral phyllotaxis on long shoots, and in dense spiral clusters of 15–45 together on short shoots; they vary fr ...

Dehydration
In physiology, dehydration is a lack of total body water, with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in divers. Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over ten percent of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs at a loss of between fifteen and twenty-five percent of the body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration is characterized by thirst and general discomfort and is usually resolved with oral rehydration. Dehydration can cause hypernatremia (high levels of sodium ...

Tabebuia Chrysantha
''Handroanthus chrysanthus'' (araguaney or yellow ipê), formerly classified as ''Tabebuia chrysantha'', also known as ''araguaney'' in Venezuela, as ''guayacán'' in Colombia, Panama, and Ecuador, as ''tajibo'' in Bolivia, and as ''ipê-amarelo'' in Brazil, is a native tree of the intertropical broadleaf deciduous forests of South America above the Tropic of Capricorn. On May 29, 1948, ''Handroanthus chrysanthus'' was declared the National Tree of Venezuela due to its status as an emblematic native species of extraordinary beauty. Its deep yellow resembles that of the Venezuelan flag. Designation ''Chrysantha'' is derived from two Greek words, χρῡσ-ός gold + ἄνθεµον flower. Araguaney appears to derive from "aravenei", the ancient word by which the Kalina people (Caribs) designated this tree. Habitat The araguaney is found in clearings of deciduous tropical forests of the broad Guiana Shield region. It is also native to warm lands and sabanas (Vía Oriente to El ...

Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

Azuero Peninsula
Azuero Peninsula ( es, Península de Azuero) is a large peninsula in southern Panama. It is surrounded by the Pacific Ocean in the south; the Pacific and Gulf of Montijo to the west, and by the Gulf of Panama in the east. The peninsula is effectively divided into two regions; the Western Azuero and the Eastern Azuero, as no serviceable roads join the two peninsula regions past the Pan-American Highway. The Eastern Azuero Peninsula is known for baseball and is also a center of activity during the annual ''carnaval'' (carnival), with Las Tablas being the hub. Pedasi is a small fishing town with sport fishing. The Western Azuero Peninsula is known for its cattle ranching, farming, fishing, sunsets and beaches. Tourism has begun to increase in the area both for the aforementioned sport fishing, surfing and for the local charm of cities like Chitré, Las Tablas and Pedasi. Due to a rise in tourism, real estate development has begun. The area enjoys some of the best weather in Panam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
