Sword-billed Hummingbird
The sword-billed hummingbird (''Ensifera ensifera''), also known as the swordbill, is a neotropical species of hummingbird from the Andean regions of South America. It is the only member in the genus ''Ensifera.'' Among the largest species of hummingbird, it is characterized by its unusually long bill, being the only bird to have a beak longer than the rest of its body, excluding the tail. It uses its bill to drink nectar from flowers with long corollas and has coevolved with the species ''Passiflora mixta''. While most hummingbirds preen using their bills, the sword-billed hummingbird uses its feet to scratch and preen due to its bill being so long. The sword-billed hummingbird is a trap-line feeder and feeds on nectar, especially from ''Passiflora mixta'' and other passionflowers. It also hawks for insects. It breeds from February to March and builds cup nests using moss. The sword-billed hummingbird is listed as being of least concern by the International Union for Cons ...

Passiflora
''Passiflora'', known also as the passion flowers or passion vines, is a genus of about 550 species of flowering plants, the type genus of the family Passifloraceae. They are mostly tendril-bearing vines, with some being shrubs or trees. They can be woody or herbaceous. Passion flowers produce regular and usually showy flowers with a distinctive corona. There can be as many as eight coronal series, as in the case of ''P. xiikzodz''. The flower is pentamerous and ripens into an indehiscent fruit with numerous seeds. List of species Distribution ''Passiflora'' has a largely neotropic distribution, unlike other genera in the family Passifloraceae, which includes more Old World species (such as the genus ''Adenia''). The vast majority of ''Passiflora'' are found in Mexico, Central America, the United States and South America, although there are additional representatives in Southeast Asia and Oceania. New species continue to be identified: for example, '' P. xishuangbannaensis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ensis
''Ensis'' is a genus of medium-sized edible saltwater clams, littoral bivalve molluscs in the family Pharidae. ''Ensis'', or razor clams, are known in much of Scotland as spoots, for the spouts of water they eject while burrowing into the sand, when visible at low tide. This term may also colloquially include members of the genus '' Solen''. ''Ensis magnus'' are known as bendies due to their slightly curved shell. Description The shells are long, narrow, and parallel-sided. This shape resembles a closed, old-fashioned straight razor (a cut-throat razor), or a closed jackknife (pocket knife) and sometimes these clams are known as razor shells or jackknives. The shells in these species are fragile and can easily be damaged when digging for these clams. Ecology ''Ensis'' species live in clean sand on exposed beaches. They are capable of digging very rapidly; see the description under the Atlantic jackknife clam. Some clammers catch jackknives by pouring salt on the characteristic ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Santa Fe, Bogotá
Santa Fe () is the third locality of Bogotá, Capital District of Colombia. Santa Fe is part of the traditional downtown of the city of Bogotá, the area where the city was founded by Gonzalo Jiménez de Quesada on August 6, 1538. This area once comprised Bogotá's total main urban area and was known as "Santa Fe de Bogotá" with its traditional neighbourhoods. Santa Fe hosts some of the main business areas in Bogotá, and is served by the Carrera Séptima, one of the main arteries of the city. The locality hosts most of Bogotá's skyscrapers. The International Center and the financial district along the Avenida Jiménez are also located within Santa Fe.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
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 pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
