Northeast China
Northeast China or Northeastern China () is a geographical region of China, which is often referred to as "Manchuria" or "Inner Manchuria" by surrounding countries and the West. It usually corresponds specifically to the three provinces east of the Greater Khingan Range, namely Liaoning, Jilin, and Heilongjiang, but historically is meant to also encompass the four easternmost prefectures of Inner Mongolia west of the Greater Khingan. The heartland of the region is the Northeast China Plain, the largest plain in China, with an area over . It is separated from Russian Far East to the north by the Amur, Argun, and Ussuri rivers; from Korea to the south by the Yalu and Tumen Rivers; and from Inner Mongolia to the west by the Greater Khingan and parts of the Xiliao River. Due to the shrinking of its once-powerful industrial sector and decline of its economic growth and population, the region is often referred to as China's Rust Belt. As a result, a campaign named Northeast Area Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Whole-genome Sequencing
Whole genome sequencing (WGS), also known as full genome sequencing, complete genome sequencing, or entire genome sequencing, is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondria and, for plants, in the chloroplast. Whole genome sequencing has largely been used as a research tool, but was being introduced to clinics in 2014. In the future of personalized medicine, whole genome sequence data may be an important tool to guide therapeutic intervention. The tool of gene sequencing at SNP level is also used to pinpoint functional variants from association studies and improve the knowledge available to researchers interested in evolutionary biology, and hence may lay the foundation for predicting disease susceptibility and drug response. Whole genome sequencing should not be confused with DNA profilin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Asia
Central Asia, also known as Middle Asia, is a subregion, region of Asia that stretches from the Caspian Sea in the west to western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. It includes the former Soviet Union, Soviet republics of the Soviet Union, republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, which are colloquially referred to as the "-stans" as the countries all have names ending with the Persian language, Persian suffix "-stan", meaning "land of". The current geographical location of Central Asia was formerly part of the historic region of Turkestan, Turkistan, also known as Turan. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian languages, Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Asia
Western Asia, West Asia, or Southwest Asia, is the westernmost subregion of the larger geographical region of Asia, as defined by some academics, UN bodies and other institutions. It is almost entirely a part of the Middle East, and includes Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian Highlands, the Levant, the island of Cyprus, the Sinai Peninsula, and partly the Caucasus Region (Transcaucasia). The region is considered to be separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. Western Asia covers an area of , with a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caspian Tiger
The Caspian tiger was a ''Panthera tigris tigris'' population native to eastern Turkey, northern Iran, Mesopotamia, the Caucasus around the Caspian Sea, Central Asia to northern Afghanistan, and the Xinjiang region in western China. Until the Middle Ages, it was also present in Ukraine and southern Russia. It inhabited sparse forests and riverine corridors in this region until the 1970s. This population was regarded as a distinct subspecies and assessed as extinct in 2003. Results of a phylogeographic analysis evinces that the Caspian and Siberian tiger populations shared a common continuous geographic distribution until the early 19th century. Some Caspian tigers were intermediate in size between Siberian and Bengal tigers. It was also called Balkhash tiger, Hyrcanian tiger, Turanian tiger, and Mazandaran tiger ( fa, ). Taxonomy ''Felis virgata'' was a scientific name used by Johann Karl Wilhelm Illiger in 1815 for the greyish tiger in the area surrounding the Caspian Sea ...

Peninsular Malaysia
Peninsular Malaysia ( ms, Semenanjung Malaysia; Jawi: سمننجڠ مليسيا), or the States of Malaya ( ms, Negeri-negeri Tanah Melayu; Jawi: نڬري-نڬري تانه ملايو), also known as West Malaysia or the Malaysian Peninsula, is the part of Malaysia that occupies the southern half of the Malay Peninsula in Southeast Asia and the nearby islands. Its area totals , which is nearly 40% of the total area of the country; the other 60% is in East Malaysia. For comparison, it is slightly larger than England (130,395 km2). It shares a land border with Thailand to the north and a maritime border with Singapore to the south. Across the Strait of Malacca to the west lies the island of Sumatra, and across the South China Sea to the east lie the Natuna Islands of Indonesia. At its southern tip, across the Strait of Johor, lies the island country of Singapore. Peninsular Malaysia accounts for the majority (roughly 81.3%) of Malaysia's population and economy; as of 2017, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malayan Tiger
The Malayan tiger is a tiger from a specific population of the ''Panthera tigris tigris'' subspecies that is native to Peninsular Malaysia. This population inhabits the southern and central parts of the Malay Peninsula and has been classified as critically endangered on the IUCN Red List since 2015. , the population was estimated at 80 to 120 mature individuals with a continuous declining trend. In the Malay language, the tiger is called ''harimau'', also abbreviated to ''rimau''. It is also known as the southern Indochinese tiger, to distinguish it from tiger populations in northern parts of Indochina, which are genetically different to this population. Taxonomy ''Felis tigris'' was the scientific name used by Carl Linnaeus in 1758 for the tiger. ''Panthera tigris corbetti'' was proposed by Vratislav Mazák in 1968 for the tiger subspecies in Southeast Asia. ''Panthera tigris jacksoni'' was proposed in 2004 as a subspecies as a genetic analysis indicated differences in mtD ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as in 1804, and the ...

Indochinese Tiger
The Indochinese tiger is a population of the ''Panthera tigris tigris'' subspecies that is native to Southeast Asia. This population occurs in Myanmar, Thailand, and Laos. In 2011, the population was thought to comprise 342 individuals, including 85 in Myanmar and 20 in Vietnam, with the largest population unit surviving in Thailand estimated at 189 to 252 individuals during 2009 to 2014. Taxonomy Vratislav Mazák proposed ''Panthera tigris corbetti'' as a scientific name for this specific population in 1968 based on skin colouration, marking pattern and skull dimensions. It was named in honor of Jim Corbett. In 2017, the Cat Classification Task Force of the Cat Specialist Group revised felid taxonomy and now recognizes the tiger populations of mainland South and Southeast Asia as belonging to the nominate subspecies ''P. tigris tigris''. Results of a genetic study published in 2018 supported six Monophyly, monophyletic clades based on whole genome sequencing analysis of 32 tiger ...
