Neill's Long-tailed Giant Rat
Neill's long-tailed giant rat (''Leopoldamys neilli'') is a species of rodent in the family Muridae. It is found in Thailand, Laos, Vietnam, and possibly Myanmar. Its natural habitats are subtropical or tropical dry shrubland and rocky areas. ''Leopoldamys neilli'' is threatened by the destruction of limestone karst habitats. Six highly differentiated genetic lineages of ''Leopoldamys neilli'' were found in Kanchanaburi, West Central ( Saraburi-Lopburi), East Central ( Saraburi-Nakhon Ratchasima), Loei, Nan, and Phrae provinces of Thailand respectively.Alice Latinne, Surachit Waengsothorn, Vincent Herbreteau, Johan R.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Leopoldamys
''Leopoldamys'' is a genus of rodents in the family Muridae The Muridae, or murids, are either the largest or second-largest family of rodents and of mammals, containing approximately 870 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia. ... endemic to Southeast Asia.

Rats Of Asia
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include ''Neotoma'' (pack rats), ''Bandicota'' (bandicoot rats) and ''Dipodomys'' (kangaroo rats). Rats are typically distinguished from mouse, mice by their size. Usually the common name of a large muroid rodent will include the word "rat", while a smaller muroid's name will include "mouse". The common terms ''rat'' and ''mouse'' are not Taxonomy (biology), taxonomically specific. There are 56 known species of rats in the world. Species and description The best-known rat species are the black rat (''Rattus rattus'') and the brown rat (''Rattus norvegicus''). This group, generally known as the Old World rats or true rats, originated in Asia. Rats are bigger than most Old World mouse, mice, which are their relatives, but seldom weigh over in the wild.

Limestone Rat
The limestone rat (''Niviventer hinpoon'') is a species of rodent in the family Muridae found only in the limestone karsts of Saraburi, Lopburi, Nakhon Sawan provinces, central Thailand. It is listed as an endangered species An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, inv ... due to its highly fragmented limestone karst habitat that is currently threatened by mining.

Gene Flow
In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic variation, genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population. It has been shown that it takes only "one migrant per generation" to prevent populations from diverging due to Genetic drift, drift. Populations can diverge due to Natural selection, selection even when they are exchanging alleles, if the selection pressure is strong enough. Gene flow is an important mechanism for transferring genetic diversity among populations. Migrants change the distribution of genetic diversity among populations, by modifying allele frequencies (the proportion of members carrying a particular variant of a gene). High rates of gene flow can reduce the genetic differentiation between the two groups, increasing homogeneity. Gene flow has b ...

Biodiversity Loss
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in Biodiversity, biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction (for example deforestation) and land use intensification (for example monoculture farming). Further problem areas are Air pollution, air and water pollution (including nutrient pollution), over-exploitation, Invasive alien species, invasive species and climate change. Many scientists, along with the ''Global Assessment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phrae
Phrae (; ; ) is a town ('' thesaban mueang'') and capital of Phrae Province and Mueang Phrae district.

During the late 1800s, Phrae served as a major center for the teak trade, with numerous foreign companies operating around the town. Before centralization reforms by King Chulalongkorn were untertakened, Phrae served as the capital of the Kingdom of Phrae and the seat of the royal family of Phrae. In 1902, the town served as the center for the Shan-led Ngiao rebellion, which aimed to overthrow Central Thai rule over Lan Na before being crushed. Centra ...
