A molecular phylogenetic study published in 2013 found that the genus ''Myrmeciza'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera the Yapacana antbird was moved to its own genus ''Aprositornis''. The name of the genus combines ...

Herbert Friedmann
Herbert Friedmann (April 22, 1900 – May 14, 1987) was an American ornithologist. He worked at the Smithsonian Institution for more than 30 years. In 1929 he became a fellow of the American Ornithologists' Union (AOU) and served as the President of the AOU from 1937 to 1939. He published 17 books and was noted for study of Avian brood parasites. Early life and education Herbert Friedmann grew up in Brooklyn, New York, the second of four sons. Young Friedman took advantage of educational and cultural opportunities offered in New York City, regularly visiting museums and taking advantage of standing room at the city's centers for performing arts. The Museum of Natural History, the Metropolitan Museum of Art and the Bronx Zoo were among his favorite destinations. He joined a bird club during his high school years and kept detailed notes on birds that he observed. He continued to study birds after entering the City College of New York at 16 years old and maintained a close ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 acci ...

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

Pico Da Neblina National Park
Pico da Neblina National Park ( pt, Parque Nacional do Pico da Neblina) is a national park in the state of Amazonas in the north of Brazil, bordering on Venezuela. It overlaps with several indigenous territories, which creates tensions over land use, as does the military presence due to the border location. The park includes lowlands around the Rio Negro, partly flooded, and mountains that include the highest peak in Brazil, after which the park is named. The wide variety of physical environments supports great biodiversity, including several endangered species. Location The Pico da Neblina National Park is divided between the municipalities of São Gabriel da Cachoeira (29.21%) and Santa Isabel do Rio Negro (70.79%) in the state of Amazonas. It has an area of . The park may be accessed by boat along the Igarapé Itamirim or the Cauaburi and Sá rivers. It may also be reached by small airplane from Manaus.

Jaú National Park
The Jaú National Park ( pt, Parque Nacional do Jaú) is a national park located in the state of Amazonas, Brazil. It is one of the largest forest reserve in South America, and part of a World Heritage Site. Location The name "Jaú" comes from that of one of the largest fish in Brazil, the gilded catfish or jau (''Zungaro zungaro''), after which the main river of the park is named. The park is in the Amazon biome in the Japurá-Solimões-Negro moist forests ecoregion. It covers an area of . It was created by decree 85.200 of 24 September 1980. It is administered by the Chico Mendes Institute for Biodiversity Conservation. It covers parts of the municipalities of Barcelos, Codajás and Novo Airão in the state of Amazonas.

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 ...

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.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
