Amber Mountain Rock Thrush
The Amber Mountain rock thrush (''Monticola sharpei erythronotus'') is a songbird in the family Muscicapidae, formerly placed in the Turdidae together with the other chats. It is now usually considered a subspecies of the forest rock thrush, although Clements considers it a distinct species. Distribution The Amber Mountain rock thrush is endemic to Madagascar where it occurs only on the Amber Mountain massif in the north of the island. Description This is a small forest-dwelling thrush, growing to a length of about . Males have blue hoods, chestnut upperparts, bright orange tail with brown central feathers and orange underparts. Females are mostly brown with an orange wash on the underparts and lack the blue hood. Males are distinguished from other rock-thrushes by the dark rufous back, while the females have bright orange tails and lack white streaking on the breast.

Female
Female (Venus symbol, symbol: ♀) is the sex of an organism that produces the large non-motile ovum, ova (egg cells), the type of gamete (sex cell) that fuses with the Sperm, male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, Sex-determination system, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced Secondary sex characteristic, secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Zoologica Scripta

Benson's Rock Thrush
Benson's rock thrush (''Monticola sharpei bensoni'') is a songbird in the family Muscicapidae, formerly placed in the Turdidae together with the other chats. It is usually included in the forest rock thrush (''M. sharpei'') as a subspecies; e.g. BirdLife International revised its status to subspecies in 2008., however it was recognized as a distinct species at one time. This bird is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. It is becoming rare due to habitat loss; when it was still considered a good species, it was classified as Near threatened by the IUCN.BLI (2004) Description The male has a blue head, mantle, back, wings and upper parts of the breast contrasting with an orange lower part of the breast and the belly. The female has a brown back, wings and tail and pale underparts, mottled and streaked with bold brown markings. In both sexes, the base of the outer tail feathers is orange. Males ...

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] |
Evergreen Forest
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, Live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones. Species of trees Coniferous temperate evergreen forests are most frequently dominated by species in the families. The trees include: Pinaceae and Cupressaceae. Broadleaf temperate evergreen forests include those in which Fagaceae, such as oaks and ferns are common, those in which Nothofagaceae predominate, and the eucalyptus forests of the Southern Hemisphere. There also are assorted temperate evergreen forests dominated by other families of trees, such as Lauraceae in laurel forest. Regions Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of , Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and Orinoco ba ...

Male
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...

Louis Lavauden
Louis Lavauden (19 June 1881, in Grenoble – 1 September 1935, in Anjou, Isère) was a French zoologist and forester. He was a student at the Institut agronomique et de l'Ecole forestière in Nancy, afterwards conducting zoological studies of the province Dauphiné. In 1912–13 he performed research of the fauna in Algeria and Tunisia, and following World War I, returned to Tunisia as a forester. In 1925 he took part in one of the first motorized crossings of the Sahara (from Tunis to Cotonou via Lake Chad). From 1928 he was stationed in Madagascar, where he collected zoological specimens that included a number of lemur Lemurs ( ) (from Latin ''lemures'' – ghosts or spirits) are Strepsirrhini, wet-nosed primates of the Superfamily (biology), superfamily Lemuroidea (), divided into 8 Family (biology), families and consisting of 15 genera and around 100 exist ... species.
