Araucaria Moist Forests
The Araucaria moist forests, officially classified as mixed ombrophilous forest (Portuguese: "Floresta Ombrófila Mista") in Brazil, are a montane subtropical moist forest ecoregion. The forest ecosystem is located in southern Brazil and northeastern Argentina. The ecoregion is a southern portion of the Atlantic Forest. The ecoregion also includes select areas of open field called "campos de cima da serra" or "coxilhas" (highland fields). Setting The moist forests cover an area of , encompassing a region of mountains and plateaus in the Brazilian states of São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul, and extending into Misiones Province of Argentina. The ecoregion lies above , rising to elevation on the high slopes of the Serra Geral. The ecoregion is bounded by the Alto Paraná Atlantic forests to the north, west, and south, the Cerrado savannas and shrublands to the northeast, The Serra do Mar coastal forests to the east, and the Uruguayan savanna to the so ...

Aparados Da Serra National Park
The Aparados da Serra National Park ( pt, Parque Nacional de Aparados da Serra) is a national park located in the Serra Geral range of Rio Grande do Sul and Santa Catarina states in the south of Brazil, between 29º07’—29º15’ S and 50º01’—50º10’ W. It was created in 1959 as one of Brazil's first national parks, to protect the Itaimbezinho canyon. It extends over an area of 10,250 hectares. Flora and fauna Despite its relatively small size, the park is characterised by a rich biodiversity, as result of its diverse relief and of being situated at the contact between coastal forests, grasslands and Araucaria moist forests. There have been at least 143 bird, 48 mammal, and 39 amphibian species documented in the park. Endangered fauna on the plateaus of the park include the red-spectacled amazon parrot, the maned wolf, and the cougar. On the slopes, the neotropical otter, ocelot and the brown howling monkey can be found. Conservation and threats When created in ...

Tropical And Subtropical Moist Broadleaf Forests
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lauraceae
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as ''Sassafras'', are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus ''Cassytha'' is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous. Overview The family has a worldwide distribution in tropical and warm climates. The Lauraceae are important components of tropical forests ranging from low-lying to montane. In several forested regions, Lauraceae are among the top five families in terms of the number of species present. The Lauraceae give their name to habitats know ...

Ocotea Porosa
''Ocotea porosa'', commonly called imbuia or Brazilian walnut, is a species of plant in the Lauraceae family. Its wood is very hard, and it is a major commercial timber species in Brazil. Taxonomy and naming It is often placed in the related genus, '' Phoebe''. It is commonly called imbuia, and is also known as Brazilian walnut, because its wood resembles that of some walnuts (to which it is not related). Portuguese common names (with variant spellings) include embuia, embúia, embuya, imbuia, imbúia, imbuya, canela-imbuia. Habitat The tree grows naturally in the subtropical montane Araucaria forests of southern Brazil, mostly in the states of Paraná and Santa Catarina (where it is the official state tree since 1973), and in smaller numbers in São Paulo and Rio Grande do Sul. The species may also occur in adjacent Argentina and/or Paraguay. In its native habitat it is a threatened species. Description The trees typically reach in height and in trunk diameter. ...

Dry Season
The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year. The temperate counterpart to the tropical dry season is summer or winter. Rain belt The tropical rain belt lies in the southern hemisphere roughly from October to March; during that time the northern tropics have a dry season with sparser precipitation, and days are typically sunny throughout. From April to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification, for tropical climates, a dry season month is defined as a month when average precipitation is below . The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn. Near these latitudes, there is one wet season and one dry season annually. At the ...

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...
