Jean Marie Bosser
Jean Marie Bosser (23 December 1922 – 6 December 2013), sometimes listed as Jean-Michel Bosser was a French botanist and agricultural engineer who worked extensively in Madagascar and Mauritius. Bosser was a researcher at the Laboratoire de Phanérogamie at the Muséum national d'histoire naturelle in Paris. From 1962 to 1963 he was the director of ORSTOM (Office de la recherche scientifique et technique outre-mer, now Institut de recherche pour le développement) in Antananarivo, Madagascar. Together with Thérésien Cadet and Joseph Guého he contributed to the series '' Flore des Mascareignes'' published by the Institut de recherche pour le développement (IRD), the Mauritius Sugar Industry Research Institute (MSIRI), and the Royal Botanic Gardens, Kew since 1976 and is a comprehensive work on the flora of Mauritius, Réunion, and Rodrigues. Bosser described numerous new species from Madagascar and the Mascarenes, such as '' Bulbophyllum labatii'', '' Cynanchum staubii'' and ...

Raymond Rabevohitra
Raymond is a male given name. It was borrowed into English from French (older French spellings were Reimund and Raimund, whereas the modern English and French spellings are identical). It originated as the Germanic ᚱᚨᚷᛁᚾᛗᚢᚾᛞ (''Raginmund'') or ᚱᛖᚷᛁᚾᛗᚢᚾᛞ (''Reginmund''). ''Ragin'' (Gothic) and ''regin'' (Old German) meant "counsel". The Old High German ''mund'' originally meant "hand", but came to mean "protection". This etymology suggests that the name originated in the Early Middle Ages, possibly from Latin. Alternatively, the name can also be derived from Germanic Hraidmund, the first element being ''Hraid'', possibly meaning "fame" (compare ''Hrod'', found in names such as Robert, Roderick, Rudolph, Roland, Rodney and Roger) and ''mund'' meaning "protector". Despite the German and French origins of the English name, some of its early uses in English documents appear in Latinized form. As a surname, its first recorded appearance in Bri ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'' and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Madagascar Lowland Forests
The Madagascar lowland forests or Madagascar humid forests are a tropical and subtropical moist broadleaf forests, tropical moist broadleaf forest ecoregion found on the eastern coast of the island of Madagascar, home to a plant and animal mix that is 80 to 90% endemic, with the forests of the eastern plain being a particularly important location of this endemism. They are included in the Global 200 list of outstanding ecoregions. Geography The ecoregion constitutes a narrow strip of lowland forests between Madagascar's east coast and the mountainous central highlands, from sea level to elevation. It covers an area of approximately . The ecoregion is under the direct influence of the oceanic trade winds, which maintain a warm, humid climate; rainfall is above 2,000 mm per year and can reach up to 6,000 mm on the Masoala peninsula. The lowland forests extend from Marojejy in the north to the southeast corner of the island. At the northern edge of ecoregion around Vohemar, the moi ...

Tsitongambarika
Tsitongambarika is a lowland forest in the north of Fort Dauphin (Madagascar), Fort-Dauphin, village Iabakoho, Anosy in southern Madagascar. The area supports many rare species of amphibians, birds, lemurs and reptiles; many of which are Endemism, endemic. In 2001, the site was designated as an Important Bird Area by BirdLife International and in 2015, an area of 600 km² received environmental protection by the government. The reserve is the recipient of monies raised by the British Birdwatching Fair, 2016 Rutland Birdfairin. Geography The forest is in the south of the island of Madagascar, within the Tsitongambarika massif, which consists of a series of ridges aligned from south-west to north-east. On the western boundary the Manampanihy river flows northwards. The nearest town is Tôlanaro, 9 km to the south. Tsitongambarika is the only area in the south of the country that still has significant areas of lowland forest but, due to illegal logging and shifting cultivatio ...

Anosy
Anosy is one of the 22 regions of Madagascar. It is located in the southeast of the country, on the eastern side of what was once the Toliara Province. The name ''Anosy'' means "island(s)" in Malagasy. Due to a strategic sea route running along its coast, Anosy had been an important crossroads for the Malagasy, Muslims, and Europeans. In the mid-1600s, it was the location of the first French colonial settlement in the Indian Ocean. The region was part of the Imerina Kingdom for much of the 1800s and part of the French colony of Madagascar from the late 1800s to 1960. Its exports have included human slaves (shipped to the Mascarene Islands and the United States in the 1700s), live cattle (exported to Réunion for almost 300 years), sisal, natural rubber, rosy periwinkle, graphite, uranothorianite, lobster, sapphires, and ilmenite. Due to its biodiversity and unique Wildlife of Madagascar, wildlife, efforts commenced in the 1980s to promote Environmental protection, environmen ...

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 ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
