Golden-crowned Sifaka
The golden-crowned sifaka or Tattersall's sifaka (''Propithecus tattersalli'') is a medium-sized lemur characterized by mostly white fur, prominent furry ears, and a golden-orange Crown (anatomy), crown. It is one of the smallest sifakas (genus ''Propithecus''), weighing around and measuring approximately from head to tail. Like all sifakas, it is a Vertical clinging and leaping, vertical clinger and leaper, and its diet includes mostly seeds and leaves. The golden-crowned sifaka is named after its discoverer, Ian Tattersall, who first spotted the species in 1974. However, it was not formally described until 1988, after a research team led by Elwyn L. Simons observed and captured some specimens for captive breeding. The golden-crowned sifaka most closely resembles the western forest sifakas of the ''P. verreauxi'' group, yet its karyotype suggests a closer relationship with the ''P. diadema'' group of eastern forest sifakas. Despite the similarities with both groups, more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

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, biochemically or biologically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 r ...

Duke Lemur Center
The Duke Lemur Center is a non-invasive research center housing over 200 lemurs and bush babies across 13 species. It is located at Duke University in Durham, North Carolina. According to the Center, it houses the most diverse population of lemurs outside of their native Madagascar. The center is open to the public through tours, for which visitors must make an appointment. History In 1966, a prosimian colony of approximately 90 individuals, belonging to John Buettner-Janusch, was relocated from the Center for Prosimian Biology at Yale University to Duke University, creating the Duke Lemur Center (DLC). Through the 1970s, the colony grew to approximately 700 individuals representing 33 species. The current colony ranges between 200 and 250 animals, representing approximately 13 species. Originally called the Duke University Primate Center (DUPC), the center's name was changed in April 2006 after a refocusing of the scientific goals and overall mission. Specimens from its sc ...

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this ...

List Of National Parks Of Madagascar
The national parks of Madagascar include all officially recognized protected areas as of 2015. The protected areas network of Madagascar is managed by the Madagascar National Parks Association (PNM-ANGAP). The network includes three types of protected areas: Strict Nature Reserves (IUCN category Ia), National Parks (IUCN category II) and Wildlife Reserves (IUCN category IV). At the 2003 IUCN World Parks Congress in Durban, the Malagasy President, Marc Ravalomanana, announced an initiative to more than triple the area under protection from approximately to over (from 3% to 10% of Madagascar's area). This " Durban Vision", as it has been dubbed, involved broadening the definition of protected areas in the country and legislation has been passed to allow the creation of four new categories of protected area: Natural Parks (IUCN category II), Natural Monuments (IUCN category III), Protected Landscapes (IUCN category V), and Natural Resource Reserves (IUCN category VI).

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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Slash-and-burn
Slash-and-burn agriculture is a form of shifting cultivation that involves the cutting and burning of plants in a forest or woodland to create a Field (agriculture), 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 (ecology), biomass is burned, resulting in a nutrient-rich layer of ash which makes the Soil fertility, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Poaching
Poaching is the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plants. In agricultural terms, the term 'poaching' is also applied to the loss of soils or grass by the damaging action of feet of livestock, which can affect availability of productive land, water pollution through increased runoff and welfare issues for cattle. Stealing livestock, as in cattle raiding, classifies as theft rather than poaching. The United Nations' Sustainable Development Goal 15 enshrines the sustainable use of all wildlife. It targets the taking of action on dealing with poaching and trafficking of protected species of flora and fauna to ensure their availability for present ...

Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...
