William Lutley Sclater
William Lutley Sclater (23 September 1863 – 4 July 1944) was a British zoologist and museum director. He was the son of Philip Lutley Sclater and was named after his paternal grandfather, also William Lutley Sclater. Life William's mother, Jane Anne Eliza, was the daughter of Sir David Hunter-Blair, 3rd Baronet and a sister-in-law of Sir Walter Elliot the Indian naturalist. Sclater received his Master of Arts degree in Natural Science from Keble College at Oxford in 1885. He worked for two years as a Demonstrator at Cambridge under Professor Adam Sedgwick and went on a collecting trip to British Guiana in 1886. He published about birds in ''The Ibis'' in 1887. In the same year, he received an appointment as a deputy superintendent of the Indian Museum in Calcutta from 1887 until 1891, when he joined the science faculty of Eton College. It was at Eton that he met his future wife, Charlotte Mellen Stephenson, an American divorcée whose two sons attended the school. The coupl ...

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] |
Birds Described In 1933
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] |
Endemic Birds Of Tanzania
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinnyris
''Cinnyris'' is a genus of sunbirds. Its members are sometimes included in ''Nectarinia''. They are generally known as double-collared sunbirds because the fringe of their bib usually includes a band of contrastingly coloured feathers. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed. Taxonomy The genus was introduced by the French naturalist Georges Cuvier in 1816. The type species was designated as "''Certhia splendida'' Shaw" by George Robert Gray in 1855. This taxon is a junior synonym of ''Certhia coccinigaster'' described by John Latham in 1801. This is now the splendid sunbird. The name ''Cinnyris'' is from the Ancient Greek κιννυρις (''kinnyris''), an unknown small bird mentioned by Hesychius of Alexandria Hesyc ...

Eastern Arc Mountains
The Eastern Arc Mountains is a chain of mountains found in Kenya and Tanzania. The chain runs from northeast to southwest, with the Taita Hills being in Kenya and the other ranges being in Tanzania. They are delimited on the southwest by the fault complex represented by the Makambako Gap that separates them from the Kipengere Range. To the northeast, they are delimited by more recent volcanism represented by Mount Kilimanjaro. The chain is considered a Tentative World Heritage Site. Mountain ranges The Eastern Arc Mountains forms a roughly crescent-shaped arc and consists of: # Taita Hills # North and South Pare Mountains # East and West Usambara Mountains # Nguru Mountains # Ukaguru Mountains # Uluguru Mountains # Uvidunda Mountains # Rubeho Mountains # Malundwe Mountain # Udzungwa Mountains # Mahenge Mountains Geology These mountain ranges are the oldest in East Africa, and though physically separated from each other, share a similar geomorphology and ecology. They were for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Udzungwa Mountains
The Udzungwa Mountains are a mountain range in south-central Tanzania. The mountains are mostly within Iringa Region, south of Tanzania's capital Dodoma. The Udzungwa Mountains are part of the Eastern Arc Mountains, and are home to a biodiverse community of flora and fauna with large numbers of endemic species. The mountains are home to the Hehe people, and the name Udzungwa comes from the Kihehe word “Wadzungwa", which means the people who live on mountainsides. Iringa is the largest settlement in the mountains, and the regional headquarters. Geography The Undzungwa Mountains cover an area of 16,131.40 km², the largest of the Eastern Arc ranges. The highest peak in the range is Luhombero at . The mountain range extends generally northeast-southwest. The Usangu Plain lies to the northwest, drained by the Great Ruaha River and its tributaries. The Great Ruaha River separates the Udzungwa Mountains from the Rubeho Mountains and Uvidunda Mountains to the northeast. The Kil ...

Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
