Birds Of The Bolivian Amazon
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. 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 partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Army Ant
The name army ant (or legionary ant or ''marabunta'') is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioural and ecological syndrome. This syndrome is often referred to as "legionary behaviour", and may be an example of convergent evolution. Most New World army ants belong to the genera ''Cheliomyrmex'', ''Neivamyrmex'', ''Nomamyrmex'', ''Labidus'', and ''Eciton''. The largest genus is ''Neivamyrmex'', which contains more than 120 species; the most predominant species is ''Eciton burchellii''; its common name "army ant" is considered to b ...

Costus
''Costus'' is a group of herbaceous perennial plants in the family Costaceae, described by Linnaeus as a genus in 1753. It was formerly known as ''Hellenia'' after the Finnish botanist Carl Niclas von Hellens. It is widespread through tropical and subtropical regions of Asia, Africa, and the Americas. ''Costus'' is often characterized and distinguished from relatives such as ''Zingiber'' (true ginger) by its spiraling stems. The genus as a whole is thus often called spiral gingers, but this can also refer to '' C. barbatus'' specifically. '' Costus spectabilis'' is the floral emblem of Nigeria; its flowers are represented (erroneously in red instead of yellow color) on its coat of arms. It is important not to confuse ''Costus speciosus'', ''C. spectabilis'' etc. with the herb known by the common name " costus". Some species are of importance to herbivores, such as caterpillars of the restricted demon (''Notocrypta curvifascia'') which feed on '' Costus speciosus'' (crê ...

Heliconia
''Heliconia'', derived from the Greek word (), is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the ca 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku. Many species of ''Heliconia'' are found in the tropical forests of these regions. Most species are listed as either vulnerable or data deficient by the IUCN Red List of threatened species. Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia, and Thailand. Common names for the genus include lobster-claws, toucan beak, wild plantain, or false bird-of-paradise. The last term refers to their close similarity to the bird-of-paradise flowers ('' Strelitzia''). Collectively, these plants are also simply referred to as "heliconias". Description These herbaceous plants range from 0.5 to nearly 4.5 m (1.5–15 ft) tall, depending on the species. The simple leaves of thes ...

Guadua
''Guadua'' is a Neotropical genus of thorny, clumping bamboo in the grass family, ranging from moderate to very large species. Physically, '' Guadua angustifolia'' is noted for being the largest Neotropical bamboo. The genus is similar to '' Bambusa'' and is sometimes included in that genus. Several animals are, to a various extent, associated with stands of ''Guadua'' bamboo, for example several species of seedeaters, and the Amazon and Atlantic Bamboo Rats. Distribution and habitats The genus can be found in a wide range from northern Mexico and Trinidad to Uruguay, but most of the species are concentrated in the Amazon basin and the Orinoco basin. They usually grow at low altitudes (below 1,500 m), but has been found up to 2,500 m. Its habitats include lowland tropical and lower-montane forest, savannas, Cerrados, gallery forest, and disturbed inter-Andean valley vegetation. Human use From a utilitarian perspective, ''Guadua'' is the most important American bamb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transitional Forest
Forest transition refers to a geographic theory describing a reversal or turnaround in land-use trends for a given territory from a period of net forest area loss (i.e., deforestation) to a period of net forest area gain. The term "landscape turnaround" has also been used to represent a more general recovery of natural areas that is independent of biome type. Causes Forest recovery resulting in net increases in forest extent can occur by means of spontaneous regeneration, active planting, or both. There are two main paths in reforestation, one emerging from economic development and another from forest scarcity. There are many causes of transition, foremost, economic development leads to industrialisation and urbanisation, pulling the labour force away from the countryside to cities. For example, in Puerto Rico, industrial policies which subsidised manufacturing led to a transition towards urban sector manufacturing and service jobs, leading to land abandonment and forest regrow ...

Várzea Forest
A várzea forest is a seasonal floodplain forest inundated by whitewater rivers that occurs in the Amazon biome. Until the late 1970s, the definition was less clear and várzea was often used for all periodically flooded Amazonian forests. Although sometimes described as consisting only of forest, várzea also contains more open, seasonally flooded habitats such as grasslands, including floating meadows. Description Along the Amazon River and many of its tributaries, high annual rainfall that occurs mostly within a rainy season results in extensive seasonal flooding of areas from stream and river discharge. The result is a rise in water level, with nutrient rich waters. The Iquitos várzea ecoregion covers the margins of the upper Amazon and its tributaries. Further down are the Purus várzea in the middle Amazon, the Monte Alegre várzea and Gurupa várzea on the lower Amazon and the Marajó várzea at the mouth of the Amazon. The Marajó várzea is affected by both freshwate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
