Collared Lemur
The collared brown lemur (''Eulemur collaris''), also known as the red-collared brown lemur or red-collared lemur, is a medium-sized strepsirrhine primate and one of twelve species of brown lemur in the family Lemuridae. It is only found in south-eastern Madagascar. Like most species of lemur, it is arboreal, moving quadrupedally and occasionally leaping from tree to tree. Like other brown lemurs, this species is cathemeral (active during the day and the night), lives in social groups, primarily eats fruit, exhibits sexual dichromatism, and does not demonstrate female dominance. The species is listed as ''Endangered'' by the International Union for Conservation of Nature (IUCN) and is threatened primarily by habitat loss. Taxonomy Together with the twelve other true lemurs (genus ''Eulemur''), the collared brown lemur (''E. collaris'') is a type of lemur belonging to the family Lemuridae. Collectively, lemurs (infraorder Lemuriformes) are classified as strepsirrhine primate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin des Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mananara River
The Mananara River is one of the main rivers in eastern Madagascar. Its mouth is located at the Indian Ocean near the city of Vangaindrano in the Atsimo-Atsinanana Atsimo-Atsinanana (South East) is a region in Madagascar. Its capital is Farafangana. The region used to be part of the Fianarantsoa Province. The region extends along the southern part of the east coast of Madagascar. It is bordered by Vatovavy-F ... region. The Mananara South is formed by the merger of the Menarahaka, Itomampy, and Ionaivo. The Ionaivo rises on the slopes of Tsimahamory peak, at an approximate elevation of 1500m. The Itomampy rises not far from the Ionaivo, about 40 km from the Indian Ocean, at approximately 1600m, and runs north until it joins the Ionaivo. The Menarahaka rises in the Andringitra massif, at approximately 2000m elevation. It is joined by the Sahambano before joining the Ionaivo.Aldegheri, Marius.

Tôlanaro
Fort-Dauphin (Malagasy Tolagnaro or Taolagnaro) is a city (''commune urbaine'') on the southeast coast of Madagascar. It is the capital of the Anosy Region and of the Taolagnaro District. It has been a port of local importance since the early 1500s. A new port, the Ehoala Port was built in 2006–2009. Fort-Dauphin was the first French settlement in Madagascar. Location Fort-Dauphin was initially situated on a short, narrow peninsula on the extreme southeastern coast of Madagascar. It has since grown to cover a much greater area along the ocean, almost to Mount Bezavona. Climate Fort-Dauphin has a tropical rainforest climate, though it is less rainy than areas further north on the eastern Malagasy coast. Being closer to the centre of the subtropical anticyclones than other parts of Madagascar, most rainfall is orographic, and tropical cyclones are not as common as in more northerly parts of the island. History The bay of Fort-Dauphin was found by a Portuguese Captain i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Red Lemur
The red lemur (''Eulemur rufus''), also known as the rufous brown lemur or northern red-fronted lemur, is a species of lemur from Madagascar. Until 2001, the species ''E. rufus'' was considered a subspecies of the common brown lemur, ''E. fulvus'', after which it was classified as its own species. In December 2008, the species was split into two separate species, the red lemur, ''E. rufus'', distributed in dry lowland forests in northwestern Madagascar, and the red-fronted lemur, ''E. rufifrons'', distributed in southwest and eastern Madagascar. The species split was based on genetic and morphological evidence. Mitochondrial DNA analysis indicates that ''E. rufifrons'' may be more closely related to the common brown lemur (''E. fulvus''), white-headed lemur (''E. albifrons'') and Sanford's brown lemur (''E. sanfordi'') than it is to ''E. rufus''. The red lemur's range covers dry deciduous forests in southwestern Madagascar between the Betsiboka River to the north and the Tsiribi ...
