Euryceros
The helmet vanga (''Euryceros prevostii'') is a distinctive-looking bird of the vanga family, Vangidae, and is classified in its own genus, ''Euryceros''. It is mainly blue-black, with rufous wings and a huge arched blue bill. It is restricted to lowland and lower montane rainforests of northeastern Madagascar. Its diet is composed of invertebrates, predominantly insects. The species is threatened by habitat loss. Taxonomy The helmet vanga is the only member of the genus ''Euryceros''. Like most vangas it was originally placed in the shrike family, Laniidae. When the ornithologist Austin L. Rand moved the majority of the vangas into a separate family in 1936, he placed the helmet vanga in its own monotypic family, Eurycerotidae. It was moved to the vanga family by J. Dorst in 1960. The closest relative within the family is believed to be the rufous vanga, which is thought to have split from the helmet vanga 800,000 years ago. The specific name ''prevostii'' commemorates the Fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vanga
The family Vangidae (from ''vanga'', Malagasy for the hook-billed vanga, ''Vanga curvirostris'') comprises a group of often shrike-like medium-sized birds distributed from Asia to Africa, including the vangas of Madagascar to which the family owes its name. Many species in this family were previously classified elsewhere in other families. Recent molecular techniques made it possible to assign these species to Vangidae, thereby solving several taxonomic enigmas. Taxonomy In addition to the small set of Malagasy species traditionally called the vangas, Vangidae includes some Asian groups: the woodshrikes (''Tephrodornis''), flycatcher-shrikes (''Hemipus'') and philentomas. Vangidae belongs to a clade of corvid birds that also includes bushshrikes (Malaconotidae), ioras (Aegithinidae) and the Australian butcherbirds, magpies and currawongs (Cracticidae) and woodswallows ( Artamidae), which has been defined as the superfamily Malaconotoidea. They seem closely related to som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marojejy National Park
Marojejy National Park () is a national park in the Sava region of northeastern Madagascar. It covers and is centered on the Marojejy Massif, a mountain chain that rises to an elevation of . Access to the area around the massif was restricted to research scientists when the site was set aside as a strict nature reserve in 1952. In 1998, it was opened to the public when it was converted into a national park. It became part of the World Heritage Site known as the Rainforests of the Atsinanana in 2007. "Unique in the world, a place of dense, jungly rainforests, sheer high cliffs, and plants and animals found nowhere else on earth", Marojejy National Park has received plaudits in the ''New York Times'' and ''Smithsonian Magazine'' for its natural beauty and rich biodiversity that encompasses critically endangered members of the silky sifaka. To that end, a global consortium of conservation organizations, including the Lemur Conservation Foundation, Duke Lemur Center and Madag ...

René Primevère Lesson
René ('' born again'' or ''reborn'' in French) is a common first name in French-speaking, Spanish-speaking, and German-speaking countries. It derives from the Latin name Renatus. René is the masculine form of the name (Renée being the feminine form). In some non-Francophone countries, however, there exists the habit of giving the name René (sometimes spelled without an accent) to girls as well as boys. In addition, both forms are used as surnames (family names). René as a first name given to boys in the United States reached its peaks in popularity in 1969 and 1983 when it ranked 256th. Since 1983 its popularity has steadily declined and it ranked 881st in 2016. René as a first name given to girls in the United States reached its peak in popularity in 1962 when it ranked 306th. The last year for which René was ranked in the top 1000 names given to girls in the United States was 1988. Persons with the given name * René, Duke of Anjou (1409–1480), titular king of Naples ...

Endemic Birds Of Madagascar
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] |

Newsletter Of The Working Group On Madagascar Birds
A newsletter is a printed or electronic report containing news concerning the activities of a business or an organization that is sent to its members, customers, employees or other subscribers. Newsletters generally contain one main topic of interest to its recipients. A newsletter may be considered grey literature. E-newsletters are delivered electronically via e-mail and can be viewed as spamming if e-mail marketing is sent unsolicited. The newsletter is the most common form of serial publication. About two-thirds of newsletters are internal publications, aimed towards employees and volunteers, while about one-third are external publications, aimed towards advocacy or special interest groups. History In ancient Rome, newsletters were exchanged between officials or friends. By the Middle Ages, they were exchanged between merchant families. Trader's newsletters covered various topics such as the availability and pricing of goods, political news, and other events that would i ...

IUCN
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon is Vulnerable when it is not critically endangered or Endangered but ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causin ...

Courtship Feeding
A nuptial gift is a nutritional gift given by one partner in some animals' sexual reproduction practices. Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor. Often, such a gift will improve the fitness of the recipient as well. This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient. Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three. Edible and inedible nuptial gifts Many nuptial gifts are a source of nutrition for the recipient. In many species of animals, including birds, insects, and spiders, this takes the form of a food item that is transferred from a male to a female just prior to copulation. This is a behavior known as courtship feeding. Inedible tokens may include items ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
