George Shaw (biologist)
George Kearsley Shaw (10 December 1751 – 22 July 1813) was an English botanist and zoologist. Life Shaw was born at Bierton, Buckinghamshire, and was educated at Magdalen Hall, Oxford, receiving his M.A. in 1772. He took up the profession of medical practitioner. In 1786 he became the assistant lecturer in botany at the University of Oxford. He was a co-founder of the Linnean Society in 1788, and became a fellow of the Royal Society in 1789. In 1791 Shaw became assistant keeper of the natural history department at the British Museum, succeeding Edward Whitaker Gray as keeper in 1806. He found that most of the items donated to the museum by Hans Sloane were in very bad condition. Medical and anatomical material was sent to the museum at the Royal College of Surgeons, but many of the stuffed animals and birds had deteriorated and had to be burnt. He was succeeded after his death by his assistant Charles Konig. Works Shaw published one of the first English descriptions with s ...

Bird
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. B ...

Lybiidae
The African barbets are birds in the family Lybiidae. There are 43 species ranging from the type genus ''Lybius'' of forest interior to the tinkerbirds (''Pogoniulus'') of forest and scrubland. They are found throughout sub-Saharan Africa, with the exception of the far south-west of South Africa. The African terrestrial barbets, Trachyphoninae, range from the southern Sahara to South Africa. Members of one genus, ''Trachyphonus'', are the most open-country species of barbets. The subfamily Lybiinae contains the African arboreal barbets. There are 37 species of Lybiinae in 6 genera. Description and ecology Most African barbets are about long, plump-looking, with large heads, and their heavy bill is fringed with bristles; the tinkerbirds are smaller, ranging down to the red-rumped tinkerbird (''Pogoniulus atroflavus'') at and . They are mainly solitary birds, eating insects and fruit. Figs and numerous other species of fruiting tree and bush are visited. An individual barbet may ...

Riparian Forest
A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, sink or reservoir. Etymology The term riparian comes from the Latin word ''ripa'', 'river bank'; technically it only refers to areas adjacent to flowing bodies of water such as rivers, streams, sloughs and estuaries. However, the terms ''riparian forest'' and ''riparian zone'' have come to include areas adjacent to non-flowing bodies of water such as ponds, lakes, playas and reservoirs. Characteristics Riparian forests are subject to frequent inundation. Riparian forests help control sediment, reduce the damaging effects of flooding and aid in stabilizing stream banks. Riparian zones are transition zones between an upland terrestrial environment and an aquatic environment. Organisms found in this zone are adapted to periodic flooding. Many not only tolerate it, but require it in order to maintain health an ... [...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 re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early 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 regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Black-breasted Barbet
The black-breasted barbet (''Pogonornis rolleti'') is a species of bird in the Lybiidae family. It is found in Central African Republic, Chad, Sudan, South Sudan, and the extreme northeast of Democratic Republic of Congo and northern Uganda. It occurs in woodlands of the eastern Sahel, between 200m and 1200m altitude (and as high as 2134m in western Sudan). Taxonomy This species is monotypic. Distribution and habitat The black-breasted barbet's range is largely in South Sudan. It is however known from Zakouma National Park Zakouma National Park is a national park in southeastern Chad, straddling the border of Guéra Region and Salamat Region. Zakouma is the nation's oldest national park, declared a national park in 1963 by presidential decree, giving it the highes ..., where birders do go to search for it.

Bearded Barbet
The bearded barbet (''Lybius dubius'') is an African barbet. Barbets are near passerine birds with a worldwide tropical distribution, although New World and Old World barbets are placed in different families. The barbets get their name from the bristles which fringe their heavy bills. The bearded barbet is a common resident breeder in tropical west Africa. It is an arboreal species of gardens and wooded country which eats fruit, although the young are fed on insects. It nests in a tree hole, laying 2 white eggs. This is a conspicuous, large barbet at . It is fairly plump, with a short neck, large head and a shortish tail. The adult has a black crown, back, tail and breast band. The throat and belly are red and there is a yellow eye patch. The rump is white. The massive bill is very thick and yellow, and the well developed clump of bristles at its base give the species its name. Sexes are similar. The call is a growling . The bearded barbet is found in well-wooded areas with plent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solanum
''Solanum'' is a large and diverse genus of flowering plants, which include three food crops of high economic importance: the potato, the tomato and the eggplant (aubergine, brinjal). It is the largest genus in the nightshade family Solanaceae, comprising around 1,500 species. It also contains the so-called horse nettles (unrelated to the genus of true nettles, ''Urtica''), as well as numerous plants cultivated for their ornamental flowers and fruit. ''Solanum'' species show a wide range of growth habits, such as annuals and perennials, vines, subshrubs, shrubs, and small trees. Many formerly independent genera like '' Lycopersicon'' (the tomatoes) and ''Cyphomandra'' are now included in ''Solanum'' as subgenera or sections. Thus, the genus today contains roughly 1,500–2,000 species. Name The generic name was first used by Pliny the Elder (AD 23–79) for a plant also known as , most likely ''S. nigrum''. Its derivation is uncertain, possibly stemming from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
