Crowned Sifaka
The crowned sifaka (''Propithecus coronatus'') is a sifaka endemic to western Madagascar, a part of the world where nature and its biological diversity faces enormous and devastating consequences resulting from anthropogenic activities. It is a species of lemur belonging to the Idriidae family, it is of comparable size to the Golden-crowned sifaka and up to a meter in length, of which 47-57 centimeters are tail. The species is an arboreal vertical climber and leaper whose diet consists of leaves, fruits and flowers. It is threatened by habitat destruction caused by human activities and is currently classified as critically endangered by the IUCN. Conservation planning needs to take local people needs and views into account in order to be successful over the long term. Taxonomy The crowned sifaka was formerly believed to be a subspecies of either Verreaux's sifaka or Von der Decken's sifaka, but is now considered a valid species following a 2007 analysis of the cranium.

Alphonse Milne-Edwards
Alphonse Milne-Edwards (Paris, 13 October 1835 – Paris, 21 April 1900) was a French mammalogist, ornithologist, and carcinologist. He was English in origin, the son of Henri Milne-Edwards and grandson of Bryan Edwards, a Jamaican planter who settled at Bruges (then in France). Milne-Edwards obtained a medical degree in 1859 and became assistant to his father at the ' in 1876. He became the director of the in 1891, devoting himself especially to fossil birds and deep-sea exploration. In 1881, he undertook a survey of the Gulf of Gascony with Léopold de Folin and worked aboard the ''Travailleur'' and the ''Talisman,'' researching the seas off the Canary Islands, the Cape Verde Islands, and the Azores. For this, he received a gold medal of the Royal Geographical Society. His major ornithological works include ' published in two parts in 1867 and 1872, ' 1866–1874 and ' 1868–1874. His study of fossils led to the discovery of tropical birds such as trogons and parrots from p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

EAZA Ex-situ Programme
The EAZA Ex-situ Programme (EEP) is a population management and Ex situ conservation, conservation programme by European Association of Zoos and Aquaria, European Association of Zoos and Aquaria (EAZA) for wild animals living in European zoos. The programme was formerly known as the European Endangered Species Programme. Each EEP has a coordinator who is assisted by a species committee. The coordinator collects information on the status of all the animals kept in EAZA zoos and aquariums of the species for which he or she is responsible, produces a Breed registry, studbook, carries out demographic and genetic analyses, produces a plan for the future management of the species and provides recommendations to participating institutions. Together with the EAZA Species Committee, recommendations are made each year about relocating and breeding animals, and the conditions of such a move (breeding loan, exchange, term free disposition, etc.). Even though EEP participation is mainly reserv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2009 Malagasy Political Crisis
The 2009 Malagasy political crisis began on 26 January 2009 with the political opposition movement led by Antananarivo mayor Andry Rajoelina, which sought to oust President Marc Ravalomanana from the presidency. The crisis reached its climax in the 2009 Malagasy coup d'état when Andry Rajoelina was declared the president of the High Transitional Authority of Madagascar on 21 March 2009, five days after Ravalomanana transferred his power to a military council and fled to South Africa. The international community immediately condemned the leader and his ascension as unconstitutional, characterising the move as a coup. Financial support and foreign investments stopped, and the country fell into one of the worst economic crises in its history. The SADC and the African Union were designated to supervise Madagascar's political reinstatement. Though the objective of the transitional government was to run presidential elections as soon as possible to relieve the tensions (despite regu ...

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slash And Burn
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom. Slash-and-burn is a type of shif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
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 ...

Paris Zoological Park
The Paris Zoological Park (), formerly known as the Bois de Vincennes Zoological Park (), and commonly called the Vincennes Zoo, is a facility of the National Museum of Natural History, located in the 12th arrondissement of Paris, which covers an area of in the bois de Vincennes. Designed to complement the Ménagerie du Jardin des plantes, this zoo is dedicated to the observation of animal behavior in a more suitable environment. Since its opening in 1934, it is remarkable for its large artificial high rock, iconic scenery of the park, visible from afar and popularly called the "Big Rock". This zoo include a greenhouse of sheltering a tropical rainforest climate A tropical rainforest climate, humid tropical climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator.

Estrus
The estrous cycle (, originally ) is the set of recurring physiological changes that are induced by reproductive hormones in most mammalian therian females. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases, otherwise known as "rest" phases, or by Pregnancy, pregnancies. Typically, estrous cycles repeat until death. These cycles are widely variable in duration and frequency depending on the species.Bronson, F. H., 1989. Mammalian Reproductive Biology. University of Chicago Press, Chicago, IL, USA. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum productivity. The male equivalent, seen primarily in ruminants, is called Rut (mammalian reproduction), rut. Differences from the menstrual cycle Mammals share the same reproductive system, includ ...

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, ''gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically or biochemically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
