Tapiche Ohara's Reserve
The Tapiche Reserve is a private conservation property located in Tapiche District, Requena Province, Loreto Region in Peru. The reserve is designated by the Peruvian government as a Private Conservation Area (PCA). Geography The reserve encompasses an area of approximately 1,540 hectares, in the Tapiche River basin, spanning both sides of the river east of the Ucayali River. It is located 340 km up river from Iquitos on the Tapiche River, and is accessible only by waterway. The Blanco and Umaita Rivers empty into the Tapiche River in the basin area. Other tributaries are the Contea, Capanahua, and Lamayacu Rivers. The reserve comprises several types of lowland Amazonian forests, including igapo, varzea, and terra firme. It is one of the few areas in the Amazon basin where these forest types can be found in close proximity. The Tapiche River basin in the area of the reserve exhibits a landscape containing alluvial plains and associated floodplains. The floodplains ...

Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

Harpy Eagle
The harpy eagle (''Harpia harpyja'') is a neotropical species of eagle. It is also called the American harpy eagle to distinguish it from the Papuan eagle, which is sometimes known as the New Guinea harpy eagle or Papuan harpy eagle. It is the largest and most powerful raptor found throughout its range, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of Central America. In Brazil, the harpy eagle is also known as royal-hawk (in pt, gavião-real). The genus ''Harpia'', together with '' Harpyopsis'' and '' Morphnus'', form the subfamily Harpiinae. Taxonomy The harpy eagle was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Vultur harpyja'', after the mythological beast harpy.

Amazonian Manatee
The Amazonian manatee (''Trichechus inunguis'') is a species of manatee that lives in the Amazon Basin in Brazil, Peru, Colombia and Ecuador. It has thin, wrinkled brownish or gray colored skin, with fine hairs scattered over its body and a white chest patch. It is the smallest of the three extant species of manatee.''Trials of a Primatologist.'' - smithsonianmag.com. Accessed March 16, 2008. Taxonomy The specific name, ''inunguis'' is Latin for "nailless." The genus name ''Trichechus'', comes from Latin meaning "hair", referencing the whiskers around the manatee's mouth.Physical characteristics The Amazonian manatee is the smallest member of the manatee family and can be distinguished b ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilian Tapir
The South American tapir (''Tapirus terrestris''), also commonly called the Brazilian tapir (from the Tupi ''tapi'ira''), the Amazonian tapir, the maned tapir, the lowland tapir, the ''anta'' (Portuguese), and ''la sachavaca'' (literally "bushcow", in mixed Quechua and Spanish), is one of the four recognized species in the tapir family (of the order '' Perissodactyla'', with the mountain tapir, the Malayan tapir, and the Baird's tapir). It is the largest surviving native terrestrial mammal in the Amazon. Most classification taxons also include ''Tapirus kabomani'' (also known as the little black tapir or kabomani tapir) as also belonging to the species ''Tapirus terrestris'' (Brazilian tapir), despite its questionable existence and the overall lack of information on its habits and distribution. The specific epithet derives from ''arabo kabomani'', the word for tapir in the local Paumarí language. The formal description of this tapir did not suggest a common name for the species. ...

Giant Armadillo
The giant armadillo (''Priodontes maximus''), colloquially ''tatu-canastra'', ''tatou'', ''ocarro'' or ''tatú carreta'', is the largest living species of armadillo (although their extinct relatives, the Glyptodontidae, glyptodonts, were much larger). It lives in South America, ranging throughout as far south as northern Argentina. This species is considered vulnerable to extinction. The giant armadillo prefers termites and some ants as prey, and often consumes the entire population of a termite mound. It also has been known to prey upon worms, larvae and larger creatures, such as spiders and snakes, and plants. Some giant armadillos have been reported to have eaten bees by digging into beehives. At least one zoo park, in Villavicencio, Colombia – ''Los Ocarros'' – is dedicated to this animal. Description The giant armadillo is the largest living species of armadillo, with 11 to 13 hinged bands protecting the body and a further three or four on the neck. Its body is dark ...

Bald Uakari
The bald uakari (''Cacajao calvus'') or bald-headed uakari is a small New World monkey characterized by a very short tail; bright, crimson face; a bald head; and long coat. The bald uakari is restricted to várzea forests and other wooded habitats near water in the western Amazon of Brazil and Peru. Taxonomy There are four recognized subspecies of the bald uakari, each of which is considered vulnerable to extinction: * White bald-headed uakari, ''Cacajao calvus calvus'' * Ucayali bald-headed uakari, ''Cacajao calvus ucayalii'' * Red bald-headed uakari, ''Cacajao calvus rubicundus'' * Novae's bald-headed uakari, ''Cacajao calvus novaesi'' Description The bald uakari weighs between 2.75 and 3.45 kg (6.1 and 7.6 lb), with head and body lengths average 45.6 cm (18.0 in) (male) and 44.0 cm (17.3 in) (female). In general, the bald uakari has a long, shaggy coat ranging from white in color to red and its head is bald. The tail is bob-like and rather s ...

Jaguar
The jaguar (''Panthera onca'') is a large cat species and the only living member of the genus '' Panthera'' native to the Americas. With a body length of up to and a weight of up to , it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainfo ...

Relative Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Restinga
Restingas () are a distinct type of coastal tropical and subtropical moist broadleaf forest in eastern Brazil. They form on sandy, acidic, and nutrient-poor soils, and are characterized by medium-sized trees and shrubs adapted to the drier and nutrient-poor conditions. One of the most notable restingas is the Restinga da Marambaia (in Rio de Janeiro), which is owned and kept by the Brazilian Army. Ecoregions The World Wildlife Fund distinguishes two ''Restinga'' ecoregions. * Atlantic Coast restingas — found in several enclaves along Brazil's east coast from Rio Grande do Norte state in northeastern Brazil to Rio Grande do Sul state in southern Brazil, covering an area of that extends from the tropics to the subtropics. Its flora and fauna shares affinities with the humid Atlantic forest of eastern Brazil. * Northeastern Brazil restingas — found along the northern coast of Brazil, in Maranhão, Piauí, and Ceará states. Its flora and fauna are distinct from that of the Atl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meander
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank ( cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. Charlton, R., 2007. ''Fundamentals ...

Oxbow Lake
An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. In South Texas, oxbows left by the Rio Grande are called '' resacas''. In Australia, oxbow lakes are called billabongs. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Because oxbow lakes are stillwater lakes, with no current flowing through them, the entire lake gradually silts up, becoming a bog or swamp and then evaporating completely. When a river reaches a low-lying plain, often in its final course to the sea or a lake, it meanders wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
