Sibree's Dwarf Lemur
Sibree's dwarf lemur (''Cheirogaleus sibreei'') is a small nocturnal lemur endemic to Madagascar. The name of this dwarf lemur commemorates the English missionary and naturalist James Sibree (1836–1929). In 2010, a research team confirmed that they had found the only known living population of Sibree's dwarf lemurs several years before. The species was long believed extinct, following the destruction of its first recorded forest habitat. This was also the first confirmation of Sibree's dwarf lemur as a unique species. * Sibree's dwarf lemur spends the winter by hibernating Hibernation is a state of minimal activity and metabolic depression undergone by some animal species.

Charles Immanuel Forsyth Major
Charles Immanuel Forsyth Major (15 August 1843, Glasgow – 25 March 1923, Munich) was a Scottish-born, Swiss physician, zoologist and vertebrate palaeontologist. Major was born in Glasgow and studied at Basel and Zurich Universities in Switzerland and later Göttingen in Germany. He graduated in medicine at Basel in 1868 and became a physician in Florence, Italy. Like many early naturalists he spent his free time studying fossil mammals. His first publication was on fossil primates in 1872. The Italian government supported him in 1877 and he collected fossils from Calabria, Corsica, Sardinia, and Sicily. In 1886, he stopped practising as a physician and began to study fossils in the Greek Archipelago with his collections going to the College Galliard at Lausanne and to the British Museum (Natural History). In the British Museum collections he took a keen interest in material from Madagascar. He studied the lemur fauna, both extant and extinct, discovered the new family Megaladap ...

Mammals Of Madagascar
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Endemic Fauna 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] |

Scientific Reports
''Scientific Reports'' is a peer-reviewed open-access scientific mega journal published by Nature Portfolio, covering all areas of the natural sciences. The journal was established in 2011. The journal states that their aim is to assess solely the scientific validity of a submitted paper, rather than its perceived importance, significance, or impact. In September 2016, the journal became the largest in the world by number of articles, overtaking '' PLOS ONE''. Abstracting and indexing The journal is abstracted and indexed in the Chemical Abstracts Service, the Science Citation Index Expanded, and selectively in Index Medicus/MEDLINE/PubMed. According to the ''Journal Citation Reports'', the journal has a 2021 impact factor 4.996. Reviewing policy The ''Guide to Referees'' states that to be published, "a paper must be scientifically valid and technically sound in methodology and analysis", and reviewers have to ensure manuscripts "are not assessed based on their perceived impor ...

Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
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 pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Sibree
James Sibree (1836–1929) was an English missionary in Madagascar with an interest in the natural history and cultural history of the island. He was a contemporary of the French naturalist Alfred Grandidier and wrote detailed books about the flora and fauna of Madagascar, the country's general history, and the mission history on the island. He also helped revise the Malagasy Bible and wrote several works in the Malagasy language. He was a vocal advocate of Malagasy independence prior to the French invasion of Madagascar in 1895. Sibree also designed and helped build almost 100 new mission buildings and 50 churches in Madagascar. He was a fellow of the Royal Geographical Society and earned an honorary degree from the University of St Andrews. Swiss zoologist Charles Immanuel Forsyth Major named Sibree's dwarf lemur after him in 1896. Son of a Congregational minister, he apprenticed as a civil engineer before travelling to Antananarivo, Madagascar in 1863 on assignment from t ...

Dwarf Lemur
The dwarf lemurs are the lemurs of the genus ''Cheirogaleus''. All of the species in this genus, like all other lemurs, are native to Madagascar. Description Measuring 19–27 cm in body length with a tail about 16–17 cm, they are larger than the mouse lemur but smaller than the gentle lemur. Their heads are globular compared to the fox-like heads of the lemurs, but their muzzles are more pointed than those of the hapalemurs. Their hind limbs are slightly longer than their forelimbs, but not as elongated as in lepilemurs or indriids. Dwarf lemurs have an intermembral index of 71 on average. In contrast to most other primates, their grip is similar to that of South American monkeys with objects picked up and branches grasped between the second and third fingers, rather than between the thumb and index finger. Their nails are somewhat keeled and pointed. Dwarf lemurs roam the lower strata of the foliage in the coastal forests of eastern Madagascar. They a ...
