Ferruginous-backed Antbird
The ferruginous-backed antbird (''Myrmoderus ferrugineus'') is a species of passerine bird in the family Thamnophilidae. It inhabits the Guyanas and the northern Amazon Basin. Its natural habitat is subtropical or tropical moist lowland forests. The ferruginous-backed antbird was formerly included in the genus '' Myrmeciza''. A molecular phylogenetic study published in 2013 found that ''Myrmeciza'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants.

Presidente Figueiredo
Presidente Figueiredo is a municipality located in the Brazilian state of Amazonas. Its population was 37,193 (2020) and its area is 25,422 km2. History The name of the municipality honors , the first president of the province of Amazonas at the time of the empire. The origins of the municipality are mainly related to Novo Airão and Itapiranga, since most of the territory that today is President Figueiredo was dismembered, as well as Manaus, whose neighborhood was an influential factor in the development of the region. The first settlements in these poles date from 1657, to the place where today is the municipality of Manaus, and in 1668, the place today is the headquarters of Novo Airão. It was from these nuclei that the consolidation and expansion of the settlement of the Baixo Rio Negro took place. Integrated in the municipality of Manaus, Novo Airão became a capital district in 1938, then with the name simply Airão. It is in 1955 that the dismemberment of Manaus t ...

Myrmeciza
The white-bellied antbird (''Myrmeciza longipes''), is a passerine bird which breeds in the tropical New World from Panama to northern Brazil and in Trinidad. It is also called Swainson's antcatcher (usually in historical sources) after William John Swainson, who first described it scientifically. The genus is monotypic. Taxonomy The white-bellied antbird was described by the English naturalist William John Swainson in 1825 and given the binomial name ''Drymophila longipes''. The genus ''Myrmeciza'' was erected by the English zoologist George Robert Gray in 1841 with the white-bellied antbird as the type species. The genus formerly included more than 20 species. A molecular phylogenetic study published in 2013 found that ''Myrmeciza'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the species formerly placed in ''Myrmeciza'' were moved to 12 other genera leaving the white-bellied antbird as only the only member of the g ...

Birds Of The Guianas
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myrmoderus
''Myrmoderus'' is a genus of passerine birds in the family Thamnophilidae. The genus contains five species: * Ferruginous-backed antbird (''Myrmoderus ferrugineus'') * Cordillera Azul antbird (''Myrmoderus eowilsoni'') * Scalloped antbird (''Myrmoderus ruficauda'') * White-bibbed antbird (''Myrmoderus loricatus'') * Squamate antbird (''Myrmoderus squamosus'') The Cordillera Azul antbird was first described in 2018. The other four species were formerly included in the genus ''Myrmeciza''. A molecular phylogenetic study published in 2013 found that ''Myrmeciza'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera four species were moved to the resurrected genus ''Myrmoderus''. The genus had originally been erected in 1909 by the American ornithologist Robert Ridgway with the white-bibbed antbird as the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or su ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have t ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with syste ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon sys ...
