George Newbold Lawrence
George Newbold Lawrence (October 20, 1806 – January 17, 1895) was an American businessman and amateur ornithologist. Early life Lawrence was born in the city of New York on October 20, 1806. From his youth, Lawrence was a lover of birds and spent much of his spare time studying their habits. At sixteen years of age, he became a clerk in his father's business, becoming a partner in his father's house by age twenty. Career Lawrence conducted Pacific bird surveys for Spencer Fullerton Baird and John Cassin, and the three men co-authored ''Birds of North America'' in 1860. He sold his collection of 8,000 bird skins to the American Museum of Natural History in 1887. Fellow ornithologists honored him by naming one bird genus and 20 species after him, including both the scientific and common name of the Lawrence's goldfinch, first described by Cassin in 1852. Personal life Lawrence died on January 17, 1895 in New York City. His funeral was held at his residence, 45 East 21st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columnea
''Columnea'' is a genus of around 200 species of epiphytic herbs and shrubs in the family Gesneriaceae, native to the tropics of the Americas and the Caribbean. The tubular or oddly shaped flowers are usually large and brightly colored – usually red, yellow, or orange – sometimes resembling a fish in shape. A common name is flying goldfish plants (see also the related ''Nematanthus'') due to the unusual flower shape. The genus was named by Carl Linnaeus after the Latinized spelling of the name of the 16th-century Italian botanist Fabio Colonna (Latin: ''Fabius Columnus''). The segregate genus '' Bucinellina'' is considered by many botanists a synonym of ''Columnea''. A full list of the species now accepted in the genus, along with their synonyms, can be found at the World Checklist of Gesneriaceae. Cultivation ''Columnea'' species grow as epiphytic plants in the wild and require bright light, good air circulation, and a well-drained growing medium that is allowed ...

Birds Of The Talamancan Montane Forests
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eupherusa
''Eupherusa'' is a genus of hummingbirds in the family Trochilidae. It contains the following five species: The Mexican woodnymph was formerly placed in the genus ''Thalurania'' with other species with "woodnymph" in their English names. A molecular phylogenetic study published in 2014 found that ''Thalurania'' was monophyletic, non-monophyletic and that the Mexican woodnymph is closely related to species in ''Eupherusa''. Based on this result the Mexican woodnymph is now placed in ''Eupherusa''. References Eupherusa, Taxonomy articles created by Polbot {{hummingbird-stub ...

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] |
Synchronization
Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or ''in time''. Systems that operate with all parts in synchrony are said to be synchronous or ''in sync''—and those that are not are '' asynchronous''. Today, time synchronization can occur between systems around the world through satellite navigation signals and other time and frequency transfer techniques. Navigation and railways Time-keeping and synchronization of clocks is a critical problem in long-distance ocean navigation. Before radio navigation and satellite-based navigation, navigators required accurate time in conjunction with astronomical observations to determine how far east or west their vessel traveled. The invention of an accurate marine chronometer revolutionized marine navigation. By the end of the 19th century, important ports provided time signals in the form of a signal gun, flag, or dropping time ...

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] |
Besleria
''Besleria'' is a genus of ca. 200 species of large herbs and soft-stemmed subshrubs or shrubs in the flowering plant family Gesneriaceae.
