Atlantic Black-throated Trogon
The Atlantic black-throated trogon (''Trogon chrysochloros'') is a bird in the family Trogonidae, the trogons and quetzals. It is found in Argentina, Brazil, and Paraguay. Taxonomy and systematics What is now the Atlantic black-throated trogon was long treated as one of six subspecies of the then "black-throated trogon" (''Trogon rufus'' ''sensu lato''). Starting in 2022, the South American Classification Committee of the American Ornithological Society (AOS), the International Ornithological Congress, and the Clements taxonomy split the black-throated trogon into four species, one of them being the Atlantic black-throated trogon.Remsen, J.

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acciden ...

South American Coati
The South American coati (''Nasua nasua''), also known as the ring-tailed coati, is a coati species and a member of the raccoon family ( Procyonidae), found in the tropical and subtropical parts of South America. An adult generally weighs from and is long, with half of that being its tail.Kays, R. (2009). South American Coati (Nasua nasua), pp. 526-528 in: Wilson, D. E., and R. A. Mittermeier, eds. (2009). ''Handbook of the Mammals of the World.'' Vol. 1, Carnivores. Its color is highly variable and the rings on the tail may be only somewhat visible, but its most distinguishing characteristic is that it lacks the largely white snout (or "nose") of its northern relative, the white-nosed coati. Distribution and habitat The South American coati is widespread in tropical and subtropical South America. It occurs in the lowland forests east of the Andes as high as from Colombia and The Guianas south to Uruguay and northern Argentina. Nasua nasua occupancy is significantly and nega ...

Atlantic Forest
The Atlantic Forest ( pt, Mata Atlântica) is a South American forest that extends along the Atlantic coast of Brazil from Rio Grande do Norte state in the northeast to Rio Grande do Sul state in the south and inland as far as Paraguay and the Misiones Province of Argentina, where the region is known as Selva Misionera. The Atlantic Forest has ecoregions within the following biome categories: seasonal moist and dry broad-leaf tropical forests, tropical and subtropical grasslands, savannas, and shrublands, and mangrove forests. The Atlantic Forest is characterized by a high biodiversity and endemism. It was the first environment that the Portuguese colonists encountered over 500 years ago, when it was thought to have had an area of , and stretching an unknown distance inland, making it, back then, the second largest rainforest on the planet, only behind the Amazon rainforest. Over 85% of the original area has been deforested, threatening many plant and animal species with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Primary Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extirpated
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The number ...

Corrientes Province
Corrientes (, ‘currents’ or ‘streams’; gn, Taragui), officially the Province of Corrientes ( es, Provincia de Corrientes; gn, Taragüí Tetãmini) is a province in northeast Argentina, in the Mesopotamia region. It is surrounded by (from the north, clockwise): Paraguay, the province of Misiones, Brazil, Uruguay, and the provinces of Entre Rios, Santa Fe and Chaco. History Before the arrival of the Spanish conquest, the Kaingang, Charrua and Guaraní lived in a big area that also covered most of the current province of Corrientes. The city of Corrientes was founded on April 3, 1588 by Juan Torres de Vera y Aragón as a mid-stop between Asunción and Buenos Aires; the city flourished thanks to the traffic from the route. Jesuits erected missions in the north of the province, where they dedicated themselves to the expansion of the faith. In the wars of independence from Spain, Corrientes joined Artigas' ''Liga de los Pueblos Libres'' (1814–1820). The attack of Para ...

Misiones Province
Misiones (, ''Missions'') is one of the 23 provinces of Argentina, located in the northeastern corner of the country in the Mesopotamia region. It is surrounded by Paraguay to the northwest, Brazil to the north, east and south, and Corrientes Province of Argentina to the southwest. This was an early area of Roman Catholic missionary activity by the Society of Jesus in what was then called the Province of Paraguay, beginning in the early 17th century. In 1984 the ruins of four mission sites in Argentina were designated World Heritage Sites by UNESCO. History Indigenous peoples of various tribes lived in the area of the future province for thousands of years. At the time of European encounter, it was occupied by the Kaingang and Xokleng tribes, later followed by the Guarani tribe. The first European to visit the region, Sebastian Cabot, discovered Apipé Falls while navigating the Paraná River in December 1527. In 1541 Álvar Núñez Cabeza de Vaca reached the Iguazú ...

Paraguay River
The Paraguay River (Río Paraguay in Spanish, Rio Paraguai in Portuguese, Ysyry Paraguái in Guarani) is a major river in south-central South America, running through Brazil, Bolivia, Paraguay and Argentina. It flows about from its headwaters in the Brazilian state of Mato Grosso to its confluence with the Paraná River north of Corrientes and Resistencia. Course The Paraguay's source is south of Diamantino in the Mato Grosso state of Brazil. It follows a generally southwesterly course, passing through the Brazilian city of Cáceres. It then turns in a generally southward direction, flowing through the Pantanal wetlands, the city of Corumbá, then running close to the Brazil-Bolivia border for a short distance in the Brazilian states of Mato Grosso and Mato Grosso do Sul. From the city of Puerto Bahia Negra, Paraguay, the river forms the border between Paraguay and Brazil, flowing almost due south before the confluence with the Apa River. The Paraguay makes a long, gentle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
