Campos Rupestres
The ''campo rupestre'' ("rupestrian grassland") is a discontinuous montane subtropical ecoregion occurring across three different biomes in Brazil: Cerrado, Atlantic Forest and Caatinga. Originally, ''campo rupestre'' was used to characterize the montane vegetation of the Espinhaço Range, but recently this term has been broadly applied by the scientific community to define high altitudinal fire-prone areas dominated by grasslands and rocky outcrops. Geography ''Campo rupestre'' (sensu lato) occupies less than one percent of the Brazilian territory, 66,447km2, and it is concentrated mostly in the states of Minas Gerais, Bahia and Goiás. This ecoregion consists of a series of relatively small and isolated grasslands and rocky outcrops mostly distributed in the Espinhaço Range in eastern Brazil, surrounded by lowland and montane forests. It also forms discontinuous enclaves in other mountain ranges, such as Carajás Mountains, Serra da Canastra, Serra do Caparaó, Chapada ...

Shrubby Vegetation
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Of Eriocaulaceae(2)
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zoological ...

Soil Profile Serra Do Cipó
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stoma
In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere in a process called transpiration. Stomata are present in the sporophyte generation of all land plant groups except liverworts. In vascular plants the number, size and distribution of stomata varies widely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C4 Carbon Fixation
carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960's discovery by Marshall Davidson Hatch and Charles Roger Slack that some plants, when supplied with 14, incorporate the 14C label into four-carbon molecules first. fixation is an addition to the ancestral and more common carbon fixation. The main carboxylating enzyme in photosynthesis is called RuBisCO, which catalyses two distinct reactions using either (carboxylation) or oxygen (oxygenation) as a substrate. The latter process, oxygenation, gives rise to the wasteful process of photorespiration. photosynthesis reduces photorespiration by concentrating around RuBisCO. To ensure that RuBisCO works in an environment where there is a lot of carbon dioxide and very little oxygen, leaves generally differentiate two partially isolated compartments called mesophyll cells and bundle-sheath cells. is initially fixed in the ...

Carnivorous Plant
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Histo ..., typically insects and other arthropods. Carnivorous plants still generate some of their energy from photosynthesis. Carnivorous plants have adapted to grow in places where the soil is thin or poor in soil nutrient, nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875 Charles Darwin published ''Insectivorous Plants (book), Insectivorous Plants'', the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research. True carnivory is believed to have convergent evoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chapada Diamantina
Chapada Diamantina (; Portuguese for the "Diamond Plateau") is a region of Bahia state, in the Northeast of Brazil. This mountain range is known as “Serra do Espinhaço,” in Minas Gerais state, south of Bahia. Description The Chapada Diamantina lies at the center of Bahia State and forms the northern part of the Espinhaço Mountain Range. It has approximately and encompasses 58 municipalities. Technically this region is considered a part of the caatinga biome, and contains some of its highest elevations, most of it above . The vegetation; a product of the physiographic conditions, is known as cerrado, and consists of rocky plains, dry forests, and caatinga desert vegetation, all of which harbour a great deal of biodiversity and unique endemisms. The region is considered to have a Mesotermic climate, of the Cwb type, according to Köppen Climate classifications. It is normally quite cooler than its surrounding areas, with an average annual temperature under 22 °C. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serra Do Caparaó
Serra do Caparaó is a Brazilian mountain range located between the states of Espírito Santo and Minas Gerais. Toponym "Caparaó" is a tupi word, the etymology of which is unclear: it may come from ''capara-oca'' (house made with capara, a twisted shrub) or from ''caá-apara-ó'' (trench made of twisted shrubs).Benedito, Mouzar: ''Paca, Tatu, Cutia!: Glossário ilustrado de Tupi'' Geography Pico da Bandeira (2892 m) is the highest point in the region. Other peaks also worth mentioning are: Pico do Calçado ("Shoe Peak", 2849 m), Pico do Cristal ("Crystal Peak", 2770 m) and Morro da Cruz do Negro ("Blackman's Cross Mountain", 2658 m). The region is place for Brazil's second largest altitude, after Serra do Imeri, and the largest gap or prominence (997 m). The Caparaó Mountains are mostly covered with Atlantic Forest, the preservation of which was guaranteed with the creation in May 1961 of the Caparaó National Park.
