Please answer the following question: Information:  - The reed vole ( Microtus fortis ) is a species of vole . It is found in northern and central Eurasia , including northern China and the Korean Peninsula . This species is somewhat larger and longer - tailed than most other voles .  - In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is often problematic. For example, in a species complex, the boundaries between closely related species become unclear or disappear altogether. Other ways of defining species include similarity of DNA, morphology, or ecological niche. The presence of locally adaptive traits may further subdivide species into infraspecific taxa such as subspecies.  - Pitymys is a subgenus of voles in the genus Microtus. Species in this subgenus are:  - Deoxyribonucleic acid (DNA) is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and RNA are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix.  - A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralised government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected to any other power or state.  - Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people.  - A vole is a small rodent; a relative of the mouse, with a stouter body, a shorter, hairy tail, a slightly rounder head, smaller ears and eyes, and differently formed molars (high-crowned and with angular cusps instead of low-crowned and with rounded cusps). There are approximately 155 species of voles. They are sometimes known as meadow mice or field mice in North America and Australia. Vole species form the subfamily Arvicolinae with the lemmings and the muskrats.  - Shanghai (": Zånhae" ), often abbreviated as Hu or Shen, is one of the four direct-controlled municipalities of the People's Republic of China. It is the most populous city proper in the world, with a population of more than 24 million . It is a global financial centre and transport hub, with the world's busiest container port. Located in the Yangtze River Delta in East China, Shanghai sits on the south edge of the mouth of the Yangtze in the middle portion of the Chinese coast. The municipality borders the provinces of Jiangsu and Zhejiang to the north, south and west, and is bounded to the east by the East China Sea.  - Jurisdiction (from the Latin "ius, " meaning "law" and "" meaning "to speak") is the practical authority granted to a legal body to administer justice within a defined area of responsibility, e.g., Michigan tax law. In the federations like USA, areas of jurisdiction apply to local, state, and federal levels; e.g. the court has jurisdiction to apply federal law.  - East Asia is the eastern subregion of the Asian continent, which can be defined in either geographical or ethno-cultural terms. Geographically and geopolitically, it includes China, Hong Kong, and Macao; Mongolia and Taiwan; North and South Korea; and Japan; it covers about , or about 28% of the Asian continent, about twice the area of Europe.  - The Communist Party of China (CPC) is the founding and ruling political party of the People's Republic of China (PRC). The CPC is the sole governing party of China, although it coexists alongside eight other legal parties that comprise the United Front; these parties, however, hold no real power or independence from the CPC. It was founded in 1921, chiefly by Chen Duxiu and Li Dazhao. The party grew quickly, and by 1949 the CPC had driven the nationalist Kuomintang (KMT) government from mainland China after the Chinese Civil War, thus leading to the establishment of the People's Republic of China. The CPC is currently the world's second largest political party with a membership of 88.76 million as of 2016 (while the Indian Bharatiya Janata Party appears to have remained the largest with a membership of 110 million as of the previous year, 2015). It also controls the world's largest armed force, the People's Liberation Army.   - Alexandromys is a subgenus of voles in the genus "Microtus". Species in this subgenus are:  - Mynomes is a North American subgenus of voles in the genus "Microtus". Species in this subgenus are: References. D.E. Wilson & D.M. Reeder, 2005: Mammal Species of the World: A Taxonomic and Geographic Reference. Third Edition. The Johns Hopkins University Press, Baltimore.  - Macau (literally: "Bay Gate"), (in Portuguese, which is still widely used in the city) also spelled Macao (in English), officially the Região Administrativa Especial de Macau da República Popular da China, is an autonomous territory on the western side of the Pearl River Delta in East Asia. Macau is bordered by the city of Zhuhai in China to the North and the Pearl River Estuary to the East and South. Hong Kong lies about to its East across the Delta. With a population of 650,900 living in an area of , it is the most densely populated region in the world.  - A mouse (plural: mice) is a small rodent characteristically having a pointed snout, small rounded ears, a body-length scaly tail and a high breeding rate. The best known mouse species is the common house mouse ("Mus musculus"). It is also a popular pet. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter.  - The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World".  - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.  - Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis. The two gametes fuse during fertilization to produce DNA replication and the creation of a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination, genetic material (DNA) joins up so that homologous chromosome sequences are aligned with each other, and this is followed by exchange of genetic information. Two rounds of cell division then produce four daughter cells with half the number of chromosomes from each original parent cell, and the same number of chromosomes as both parents, though self-fertilization can occur. For instance, in human reproduction each human cell contains 46 chromosomes, 23 pairs, except gamete cells, which only contain 23 chromosomes, so the child will have 23 chromosomes from each parent genetically recombined into 23 pairs. Cell division initiates the development of a new individual organism in multicellular organisms, including animals and plants, for the vast majority of whom this is the primary method of reproduction.  - The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats. They are most closely related to the other subfamilies in the Cricetidae (comprising the hamsters and New World rats and mice). Some authorities place the subfamily Arvicolinae in the family Muridae along with all other members of the superfamily Muroidea. Some refer to the subfamily as the Microtinae or rank the taxon as a full family, the Arvicolidae.  - Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition.  - Hong Kong, officially the Hong Kong Special Administrative Region of the People's Republic of China, is an autonomous territory on the Pearl River Delta of East Asia. Macau lies across the delta to the west, and the Chinese province of Guangdong borders the territory to the north. With a total land area of and a population of over 7.3 million of various nationalities, it ranks as the world's fourth most densely populated sovereign state or territory.  - Microtus is a genus of voles found in North America, Europe, and northern Asia. The genus name refers to the small ears of these animals. About 62 species are placed in the genus. They are stout rodents with short ears, legs, and tails. They eat green vegetation such as grasses and sedges in summer, and grains, seeds, roots, and bark at other times. The genus is also called "meadow voles". (ITIS database) The species are: Subgenus "Microtus" Subgenus "Terricola" Subgenus "Mynomes" Subgenus "Alexandromys" Subgenus "Stenocranius" Subgenus "Pitymys" Subgenus "Pedomys" Subgenus "Hyrcanicola"  - Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus "Rattus", the most important of which to humans are the black rat, "Rattus rattus", and the brown rat, "Rattus norvegicus". Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats.  - Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney.  - Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data.  - Rodents (from Latin "rodere", "to gnaw") are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents; they are found in vast numbers on all continents except Antarctica. They are the most diversified mammalian order and live in a variety of terrestrial habitats, including human-made environments.  - China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower.  - A lemming is a small rodent, usually found in or near the Arctic, in tundra biomes. Lemmings are subniveal animals and together with voles and muskrats, they make up the subfamily Arvicolinae (also known as Microtinae), which forms part of the largest mammal radiation by far, the superfamily Muroidea, which also includes rats, mice, hamsters, and gerbils.
