Louis Fraser
Louis Fraser (1819 – c. 1883) was a British Zoology, zoologist and collector. In his early years, Fraser was curator of the Museum of the Zoological Society of London. Little is known about Fraser's early life. He was born in 1819 or 1820 and married Mary Ann Harrison on 17 February 1844. A son Oscar L. Fraser worked as an assistant in the Indian Museum at Calcutta around 1888. He worked for fourteen years at the museum of the Zoological Society of London. He worked with the anatomist Richard Owen on studies of the emu and rhea. He participated in the Niger expedition of 1841 as the African Civilization Society's scientist, with William Allen (admiral), Allen and Thomas Richard Heywood Thomson, Thomson. He stayed on in Fernando Po and collected. Upon his return he became in charge of Edward Smith-Stanley, 13th Earl of Derby, Lord Derby's collection at Knowsley Hall. In 1846 he was sent by Lord Derby to collect in north Africa. In 1848 he became conservator at Knowsley. He wrote ''Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Birds Described In 1840
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. Bird ...

Eriocnemis
''Eriocnemis'' is a genus of hummingbirds, which - together with the species in the genus ''Haplophaedia'' - are known as pufflegs. They occur in humid forest, woodland and shrub at altitudes of 1000 to 4800 m. asl in the Andes of Argentina, Bolivia, Peru, Ecuador, Colombia, and Venezuela. The males have a colourful green, coppery or blue plumage, and the females are generally somewhat duller. The most striking feature of both sexes in the genus ''Eriocnemis'' are their dense snow-white leg-puffs which consist of feather tufts that resemble woolly panties. One species, the black-thighed puffleg - is characterized by black coloured leg-puffs. Most have a contrasting blue, purple or coppery-red vent, but this is green in the black-thighed and emerald-bellied puffleg. Further common features of all species are the straight black bill and the slightly to deeply forked tail. The genus name was coined by the German naturalist Ludwig Reichenbach who called them ''Snowy panties''. While ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hawking (birds)
Hawking is a feeding strategy in birds involving catching flying insects in the air. The term usually refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch, though it also applies to birds that spend almost their entire lives on the wing. This technique is called "flycatching" and some birds known for it are several families of "flycatchers": Old World flycatchers, monarch flycatchers, and tyrant flycatchers. Other birds, such as swifts, swallows, and nightjars, also take insects on the wing in continuous aerial feeding. The term "hawking" comes from the similarity of this behavior to the way hawks take prey in flight, although, whereas raptors may catch prey with their feet, hawking is the behavior of catching insects in the bill. Many birds have a combined strategy of both hawking insects and gleaning them from foliage. Flycatching The various methods of taking insects have been categorized as: gleaning (per ...

Pernettya
''Gaultheria'' is a genus of about 135 species of shrubs in the family Ericaceae. The name commemorates Jean François Gaultier of Quebec, an honour bestowed by the Scandinavian Pehr Kalm in 1748 and taken up by Carl Linnaeus in his '. These plants are native to Asia, Australasia and North and South America. In the past, the Southern Hemisphere species were often treated as the separate genus ''Pernettya'', but no consistent reliable morphological or genetic differences support recognition of two genera, and they are now united in the single genus ''Gaultheria''. Description The species vary from low, ground-hugging shrubs less than tall, up to tall, or, in the case of '' G. fragrantissima'' from the Himalayas, even a small tree up to tall. The leaves are evergreen, alternate (opposite in '' G. oppositifolia'' from New Zealand), simple, and vary between species from long; the margins are finely serrated or bristly in most species, but entire in some.

Palicourea
''Palicourea'' is a plant genus in the family Rubiaceae. It contains about 200 species, which range from shrubs to small trees, and is distributed throughout the New World tropics.Taylor (2008) These plants are closely related to ''Psychotria'' and in particular its subgenus ''Heteropsychotria''. Indeed, it seems to be nothing else but a distinctively-flowered offshoot of ''Heteropsychotria''; arguably, it would thus need to be merged into ''Psychotria'' to make that genus monophyletic. On the other hand, ''Psychotria'' is extremely diverse already, so it is probably more practical to move the more distantly related species out of this genus and merge ''Heteropsychotria'' with ''Palicourea''. By a Hungarian botanist Attila Borhidi, some of the ''Psychotria'' species have been transferred into this genus. The genus is not well studied. Most species are distylous, although a few on isolated Caribbean islands seem to have lost the trait. Flowers are in racemes, having no scent, an ...

Páramo
Páramo () can refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolutionary hot spots", that meaning that it's among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ecuador) ter ...
