Myrmotherula Iheringi
Ihering's antwren (''Myrmotherula iheringi'') is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, and Peru. Taxonomy and systematics Ihering's antwren has three subspecies, the nominate ''M. i. iheringi'' ( Snethlage, 1914), ''M. i. heteroptera'' (Todd, 1927), and ''M. i. oreni'' (Miranda, Aleixo, Whitney, Silveira, Guilherme, MPD Santos & MPC Schneider, 2013). Subspecies ''M. i. oreni'' was initially described as a full species, and the same authors suggested that ''M. i. heteroptera'' also deserved to be treated as a species.Miranda, L.; Aleixo, A.; Whitney, B.M.; Silveira, L.F.; Guilherme, E.; Santos, M.P.D.; and Schneider, M.P.C.

Emilia Snethlage
Maria Emilie Snethlage (April 13, 1868 – November 25, 1929) was a German-born Brazilian naturalist and ornithologist who worked on the bird fauna of the Amazon. Snethlage collected in Brazil from 1905 until her death. She was the director of the Museu Paraense Emílio Goeldi from 1914 to 1922. Several species of birds were described by her. Early life Maria Emilie Snethlage was born in Kraatz (now part of Gransee) in the Province of Brandenburg, Prussia, and educated privately by her father Rev. Emil Snethlage, a Lutheran pastor, after the death of her mother. In 1889 she passed an examination that allowed her to teach young women at secondary school. At the age of 21 she studied French at Neuchatel and worked for a few years as a tutor in England, Ireland and Germany. She became interested in nature at an early age through the book ''Entdeckungsreisen in Feld und Flur'' by Hermann Wagner and she collected plants for a herbarium apart from sending notes on birds to Rudolf Bl ...

Birds Described In 1914
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. Bi ...

Myrmotherula
''Myrmotherula'' is a genus of insectivorous passerine birds in the antbird family, Thamnophilidae. These are all small antbirds, measuring . The genus was erected by the English zoologist Philip Sclater in 1858. The type species is the pygmy antwren. The genus currently contains the following species: Streaked group: * Moustached antwren (''Myrmotherula ignota'') * Pygmy antwren (''Myrmotherula brachyura'') * Guianan streaked antwren (''Myrmotherula surinamensis'') * Amazonian streaked antwren (''Myrmotherula multostriata'') * Pacific antwren (''Myrmotherula pacifica'') * Cherrie's antwren (''Myrmotherula cherriei'') * Klages's antwren (''Myrmotherula klagesi'') * Stripe-chested antwren (''Myrmotherula longicauda'') * Yellow-throated antwren (''Myrmotherula ambigua'') * Sclater's antwren (''Myrmotherula sclateri'') Grey group: * White-flanked antwren (''Myrmotherula axillaris'') * Silvery-flanked antwren (''Myrmotherula luctuosa'') * Slaty antwren (''Myrmotherula schi ...

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.

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 ...

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 ...
