Forest Floor
The forest floor, also called detritus or wikt:duff#Noun 2, duff, is the part of a forest ecosystem that mediates between the living, aboveground portion of the forest and the mineral soil, principally composed of dead and decaying plant matter such as rotting wood and shed leaf, leaves. In some countries, like Canada, forest floor refers to L, F and H organic horizons. It hosts a wide variety of decomposers and predators, including invertebrates, fungi, algae, bacteria, and archaea. The forest floor serves as a bridge between the above ground living vegetation and the soil, and thus is a crucial component in nutrient transfer through the biogeochemical cycle. Leaf litter and other plant litter transmits nutrients from plants to the soil. The plant litter of the forest floor (or L horizon) prevents erosion, conserves moisture, and provides nutrients to the entire ecosystem. The F horizon consists of plant material in which decomposition is apparent, but the origins of plant res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Goeldi's Marmoset
Goeldi's marmoset, or Goeldi's monkey (''Callimico goeldii''), is a small New World monkey found on the South American continent, mainly in the upper Amazon basin of Bolivia, Brazil, Colombia, and Perú. It is the only species classified in the monotypic genus ''Callimico'', thus these monkeys are sometimes referred to as "callimicos". The species takes its name from its discoverer, Swiss-Brazilian naturalist Emil August Goeldi. Likely an evolutionary adaptation for camouflage and the evasion of predators, Goeldi's marmosets are a dark-furred species, usually a blackish-gray or darker brown in color. Superficially, the short hair on their head gives them a vague resemblance to the larger woolly monkey ('' Lagothrix''); however, the back of their necks, their backside, and tails often display light, horizontal striping or highlights. Their bodies are about long, and their tails are about another long. Captive Goeldi's marmosets weigh around , while observed individuals were appr ...

Juruá River
The Juruá River ( ; ) is a southern affluent river of the Amazon River west of the Purus River. The Juruá emerges from highlands in east-central Peru, then winds its way through lowlands in Brazil, sharing with this the bottom of the immense inland Amazon depression; and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses. For most of its length, the river flows through the Purus várzea ecoregion. This is surrounded by the Juruá-Purus moist forests ecoregion. The Juruá rises among the Ucayali highlands, and is navigable and unobstructed for a distance of above its junction with the Amazon. It has a total length of approximately , and is one of the longest tributaries of the Amazon. The Médio Juruá Extractive Reserve, created in 1997, is on the left bank of the river as it meanders in a generally northeast direction through the municipality of Carauari. The lower Jur ...

The Purus River (Portuguese: ''Rio Purus''; Spanish: ''Río Purús'') is a tributary of the Amazon River in South America. Its drainage basin is , and the mean annual discharge is . The river shares its name with the Alto Purús National Park and the Purús Province (and its conformed Purús District), one of the four provinces of Peru in the Ucayali Region. Geography The Purus River rises in Peru. It defines the boundary between Peru and Brazil in the centre of the state of Acre, then runs for a short distance along the boundary of the Santa Rosa do Purus National Forest, a sustainable use conservation unit created in 2001 after it is joined by the Santa Rosa River. The Purus then flows north east through Manoel Urbano It runs through a continuous forest at the bottom of the great depression, lying between the Madeira River, which skirts the edge of the Brazilian sandstone plateau, and the Ucayali River, which hugs the base of the Andes.

Rio Acre
The Acre River (called Aquiry in the local Iñapari language; locally, ''Rio Acre'') is a long river in central South America. Course The river is born in Peru, and runs North-Eastwards, forming part of the border between Peru and Brazil and then part of the border between Bolivia and Brazil. It runs through the Brazilian states of Acre and Amazonas, before eventually running into the Purus River at Boca do Acre. It runs along the Bolivian frontier and flows northeastward to a junction with the Purus at 8° 45' South latitude. The name is also applied to a district situated on the same river and on the former boundary line of 1867, between Bolivia and Brazil. This region's area is estimated at . It is navigable from the mouth until the Xapuri River (), even farther in the wet season from January until May. The river was an important transportation artery at the end of the 19th century due to newly discovered rubber tree forests. The Rio Acre Ecological Station lies in the ...
