Campina (biome)
Campina is a Neotropical ecoregion found in the Amazon biome. It refers to vegetation that grows on infertile sandy soil with poor drainage. The term may be used to include open forest, shrubland and meadow, or may be restricted to treeless meadows. Open forest The term ''campina'' is related to ''campinarana''. The meaning of both is "wild field", and some consider that they are the same. The terms ''campina'' and ''campinarana'' both describe white sand savannas that are very poor in nutrients. They may be flooded periodically or seasonally, in which case the roots suffer from lack of aeration. The vegetation is stunted. Amazon ''campinas'' are defined as open forest on sandy soil where sunlight can reach the ground. More than half the species of orchid in the Amazon lowlands are found in this type of forest. The ''campina'' areas of the Amazon have a flowering peak in the dry season. Treeless shrubland or meadow For others, ''campina'' is distinguished as being completely treel ...

Neotropical Realm
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct f ...

Amazon Biome
The Amazon biome ( pt, Bioma Amazônia) contains the Amazon rainforest, an area of tropical rainforest, and other ecoregions that cover most of the Amazon basin and some adjacent areas to the north and east. The biome contains blackwater and whitewater flooded forest, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath and alpine tundra. Some areas are threatened by deforestation for timber and to make way for pasture or soybean plantations. Location The Amazon biome has an area of . The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin. J. J. Morrone (2006) defines the Amazonian subregion in this broader sense, divided into the biogeographical provinces of Guyana, Humid Guyana, Napo, Imeri, Roraima, Amapá, Várzea, Ucayali, Madeira, Tapajós-Xingu, Pará, Yun ...

Campinarana
Campinarana (NT0158, ), also called Rio Negro Campinarana, is a neotropical ecoregion in the Amazon biome of the north west of Brazil and the east of Colombia that contains vegetation adapted to extremely poor soil. It includes savanna, scrub and forest, and contains many endemic species of fauna and flora. Location Areas of campinarana, which may cover several thousand square kilometres, are found in the transitional region from the Guyana Shield to the Amazon basin. Large stretches of Campinarana are contained within the Japurá-Solimões-Negro moist forests, Negro-Branco moist forests, Guianan piedmont and lowland moist forests, Uatuma-Trombetas moist forests and Guianan savanna. The campinarana ecoregion totals about . Campinarana is mainly found in flat flooded areas in the Rio Negro and Rio Branco basins in the border region between Colombia, Venezuela and Bazil, but patches are found throughout the Amazon region. Areas of white-sand soils and their characteristic cam ...

Biome
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its c ...

Uatumã Sustainable Development Reserve
The Uatumã Sustainable Development Reserve ( pt, Reserva de Desenvolvimento Sustentável do Uatumã) is a sustainable development reserve in the state of Amazonas, Brazil. The land is owned by the state, but the reserve has a population of about 1,300 people engaged in sustainable agriculture, extraction and fishing. Location The Uatumã Sustainable Development Reserve is divided between the municipalities of São Sebastião do Uatumã (60.42%) and Itapiranga (39.58%) in the state of Amazonas. It has an area of . The reserve covers parts of the lower Amazon plateau and the Amazon plain. It is in the lower third of the Uatumã River basin near its mouth on the Amazon River. The Uatumã River runs through the length of the reserve from north to south. The reserve is accessible by river from Manaus, or by land via the BR-174 and AM-240 highways. History The reserve was proposed in 1996 after several studies by environmental bodies and NGOs, and in response to the demands of the ...

Bromeliad
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte '' Tillandsia'' species ...

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genus of ...
