Osbert Salvin
Osbert Salvin (25 February 1835 – 1 June 1898) was an English natural history, naturalist, Ornithology, ornithologist, and Herpetology, herpetologist best known for co-authoring ''Biologia Centrali-Americana'' (1879–1915) with Frederick DuCane Godman. This was a 52-volume encyclopedia on the natural history of Central America. Biography Osbert Salvin was born in Finchley, north London, the second son of the architect Anthony Salvin, of Hawksfold, Sussex. He was educated at Westminster School and Trinity Hall, Cambridge, taking his degree in 1857. Shortly afterwards he accompanied his second cousin by marriage, Henry Baker Tristram, in a natural history exploration of Tunisia and eastern Algeria. Their account of this trip was published in ''Ibis (journal), The Ibis'' in 1859 and 1860. In the autumn of 1857, he made the first of several visits to Guatemala, returning there with Frederick DuCane Godman in 1861. It was during this journey that the ''Biologia Centrali-Americana ...

Tepui
A tepui , or tepuy (), is a member of a family of table-top mountains or mesas found in northern South America, especially in Venezuela, western Guyana, and northern Brazil. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Notable tepuis include Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

Taxa Named By Osbert Salvin
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1884
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furth ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Macaulay Library
The Macaulay Library is the world's largest archive of animal media. It includes more than 71 million photographs, 2.6 million audio recordings, and over three hundred thousand videos covering 96 percent of the world's bird species. There are an ever-increasing numbers of insect, fish, frog, and mammal recordings. The Library is part of Cornell Lab of Ornithology of Cornell University. History Arthur Augustus Allen and Peter Paul Kellogg made the first recordings of bird sound on May 18, 1929, in an Ithaca park. They used motion-picture film with synchronized sound to record a song sparrow, a house wren, and a rose-breasted grosbeak. This was the Beginning of Cornell Library of Natural Sounds. Graduate student Albert R. Brand and Cornell undergraduate M. Peter Keane developed recording equipment for use in the open field. In the next two years they had successfully recorded more than 40 species of birds. In 1931, Peter Keane and True McLean (a Cornell professor in electrical ...

Cornell Lab Of Ornithology
The Cornell Lab of Ornithology is a member-supported unit of Cornell University in Ithaca, New York, which studies birds and other wildlife. It is housed in the Imogene Powers Johnson Center for Birds and Biodiversity in Sapsucker Woods Sanctuary. Approximately 250 scientists, professors, staff, and students work in a variety of programs devoted to the Lab's mission: interpreting and conserving the Earth's biological diversity through research, education, and citizen science focused on birds. Work at the Lab is supported primarily by its 100,000 members and supporters. The Cornell Lab produces a quarterly publication, ''Living Bird'' magazine, and an electronic newsletter delivered twice per month. It manages numerous participatory science projects and websites, including the Webby Award-winning ''All About Birds''.

Xeno-canto
xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of bird calls and sounds of orthoptera and bats. Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. All the recordings are published under one of the Creative Commons licenses, including some with open licences. Each recording on the website is accompanied by a spectrogram and location data on a map displaying geographical variation. Data from xeno-canto has been re-used in many (a few thousand) scientific papers. It has also been the source of data for an annual challenge on automatic birdsong recognition ("BirdCLEF") since 2014, conducted as part of the Conference and Labs of the Evaluation Forum. The website is supported by a number of academic and birdwatching institutions worldwide, with its primary support being in the Netherl ...

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.

Melastomataceae
Melastomataceae () is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species. Melastomes are annual or perennial herbs, shrubs, or small trees. Description The leaves of melastomes are somewhat distinctive, being opposite, decussate, and usually with 3-7 longitudinal veins arising either from the base of the blade, plinerved (inner veins diverging above base of blade), or pinnately nerved with three or more pairs of primary veins diverging from the mid-vein at successive points above the base. Flowers are perfect, and borne either singly or in terminal or axillary, paniculate cymes. Ecology A number of melastomes are regarded as invasive species once naturalized in tropical and subtropical environments outside their normal range. Examples are Koster's curse (''Clidemia hirta''), '' Pleroma semidecandrum'' and '' Miconia calvescens'', but many othe ... [...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 regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, 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 Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...
