Madagascar Hoopoe
The Madagascar hoopoe (''Upupa marginata'') is a species of hoopoe in the family Upupidae. It was previously considered a subspecies (''Upupa epops marginata'') of the hoopoe, but was split due to its vocalisations and small differences in plumage. Some taxonomists still consider all three species conspecific. Some authorities also keep the African and Eurasian hoopoe together, but split the Madagascar hoopoe. It is endemic to Madagascar, where its natural habitat is subtropical or tropical dry forest. It is a common bird and the International Union for Conservation of Nature considers its conservation status to be of least concern. Description The adult Madagascar hoopoe is about long and weighs . It has a long, decurved bill, and cinnamon-coloured plumage, the wings being boldly barred in black and white. The tail is black and a long, cinnamon crest with black-tipped feathers can be raised when the bird is alarmed. The wings are broad and rounded; the characteristic flight co ...

Isalo National Park
Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between . History and significance Isalo National Park was created in 1962 and has been administered by the Madagascar National Parks authority since 1997. The Bara people have traditionally inhabited this area, a nomadic people subsisting on cattle (zebu) farming. There are burial sites of the Bara people and some older burial sites of the Sakalava. Isalo is primarily within the Madagascar dry deciduous forests, dry deciduous forests ecoregion, an ecoregion in which natural vegetation has been reduced by almost 40% of its origin ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. 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 partners ...

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Birds Described In 1860
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furthe ...

Endemic Birds Of Madagascar
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Upupa
Hoopoes () are colourful birds found across Africa, Asia, and Europe, notable for their distinctive "Crest (feathers), crown" of feathers which can be raised or lowered at will. Two living and one extinct species are recognized, though for many years both extant species were lumped as a single species—''Upupa epops''. In fact, some taxonomists still consider the species to be Biological_specificity#Conspecific, conspecific. Some authorities also keep the African and Eurasian hoopoe together but split the Madagascar hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated as Least Concern on the IUCN Red List of Threatened Species. However, their numbers are declining in Western Europe. Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai, Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round. Taxonomy The genus ''Upupa'' was introduced in 1758 by the Swedish naturalist Carl ...

African Hoopoe
The Eurasian hoopoe (''Upupa epops'') is the most widespread species of the genus ''Upupa''. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop". The Eurasian hoopoe is native to Europe, Asia and Africa. It is migratory in the northern part of its range. Some ornithologists consider the Madagascar hoopoes as a subspecies. The African hoopoe, subspecies ''U. e. africana'' has sometimes been treated as a separate species. Taxonomy The Eurasian hoopoe was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He cited the earlier descriptions by the French naturalist Pierre Belon and by the Swiss naturalist Conrad Gessner, both of which had been published in 1555. Linnaeus placed the Eurasian hoopoe with the northern bald ibis and the red-billed chough in the genus ''Up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Subtropical Or Tropical Dry Forest
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred millimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also tend t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850. He founded the ''Journal für Ornithologie'' in 1853''.'' Biography Cabanis was born in Berlin to an old Huguenot family who had moved from France. His father Benoit-Jean (1774–1838) and mother Maria Luise (1783–1849) both came from families that were in the textile industry. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, working as a museum assistant in Carolina. He returned in 1841 with a large natural history collection. He was assistant at the Natural History Museum, Berlin, Natural History Museum of Berlin (which was at the time the Berlin University Museum) and in 1850 he became the curator of birds, taking over from Martin Lichtenstein. Charles Lucien Bonaparte had offered him a positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
