Sunda Shrew
The Sunda shrew (''Crocidura monticola'') is a species of mammal in the family Soricidae found in Indonesia and Malaysia. Populations from the Malay Peninsula, Sumatra and Borneo are now considered to belong to '' Crocidura neglecta''. The widespread species ''C. neglecta sensu lato'', exhibits high levels of diversity. The divergence among populations from Peninsular Malaysia, west Borneo and north-east Borneo is higher than that among many other recognised related species, suggesting that these might deserve specific status.

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he greatly increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allele
An allele is a variant of the sequence of nucleotides at a particular location, or Locus (genetics), locus, on a DNA molecule. Alleles can differ at a single position through Single-nucleotide polymorphism, single nucleotide polymorphisms (SNP), but they can also have insertions and deletions of up to several thousand base pairs. Most alleles observed result in little or no change in the function or amount of the gene product(s) they code or regulate for. However, sometimes different alleles can result in different observable phenotypic traits, such as different pigmentation. A notable example of this is Gregor Mendel's discovery that the white and purple flower colors in pea plants were the result of a single gene with two alleles. Nearly all multicellular organisms have two sets of chromosomes at some point in their biological life cycle; that is, they are diploid. For a given locus, if the two chromosomes contain the same allele, they, and the organism, are homozygous with re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1870
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Mammals Of Borneo
The mammal species of Borneo include 288 species of terrestrial and 91 species of marine mammals recorded within the territorial boundaries of Brunei, Indonesia and Malaysia. The terrestrial mammals are dominated by the chiroptera (102 species of bats) and rodents (61 species of rats and mice). Introduction The high diversity and endemicity of mammals is related to the many niches found in the tropical rain forest of Borneo and past Pleistocene events within the Sundaland region. During interglacial and post-glacial periods, there was migration of animal from the Asian mainland into Borneo and into Sulawesi via the Philippines. Due to lack of favourable habitats and small founder population, some species of animals have become extinct and others have radiated into endemic species. Of the 57 mammal species that were identified from archaeological remains in the Niah Caves, Sarawak, 13 were bats. Four of these were megachiropterans, '' Pteropus vampyrus'', '' Rousettus amplexicaudat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Of Malaysia
The wildlife of Malaysia is diverse, with Malaysia being a Megadiverse countries, megadiverse country. Most of the country is covered in rainforest, which hosts a huge biodiversity, diversity of plant and animal species. There are approximately 361 mammal species, 694 #Birds, bird species, 250 reptile species, and 150 frog species found in Malaysia. Its large marine territory also holds a great diversity of life, with the country's coastal waters comprising part of the Coral Triangle. Terrestrial fauna Malaysia is estimated to contain 20% of the world's animal species, and includes some of the most biodiverse areas on the planet. High levels of endemism are found in the diverse forests of Malaysian Borneo's mountains, as populations are isolated from each other by lowland forest.

Crocidura
The genus ''Crocidura'' is one of nine genera of the shrew subfamily Crocidurinae. Members of the genus are commonly called white-toothed shrews or musk shrews, although both also apply to all of the species in the subfamily. With over 180 species, ''Crocidura'' contains the most species of any mammal genus. The name ''Crocidura'' means "woolly tail", because the tail of ''Crocidura'' species are covered in short hairs interspersed with longer ones. They are found throughout all tropical and temperate regions of the Old World, from South Africa north to Europe, and east throughout Asia, as far east as the Malay Archipelago. One species, the possibly extinct Christmas Island shrew (''C. trichura''), also inhabited Christmas Island. They likely originated in Africa or Asia Minor during the Miocene, spread to Europe by the early Pliocene, and spread to eastern Asia and the Mediterranean by the Pleistocene.

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo () is the List of islands by area, third-largest island in the world, with an area of , and population of 23,053,723 (2020 national censuses). Situated at the geographic centre of Maritime Southeast Asia, it is one of the Greater Sunda Islands, located north of Java Island, Java, west of Sulawesi, and east of Sumatra. The island is crossed by the equator, which divides it roughly in half. The list of divided islands, island is politically divided among three states. The sovereign state of Brunei in the north makes up 1% of the territory. Approximately 73% of Borneo is Indonesian territory, and in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo.
