Fuxian Lake
Fuxian Lake () stretches out through Chengjiang, Jiangchuan and Huaning Counties in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third-largest in Yunnan, after Dian Lake and Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth. It is also the third-deepest fresh water lake in China, after Tianchi and Kanas Lake. Climate Fuxian Lake has humid subtropical climate (Köppen climate classification ''Cwa'') with humid summers and mild dry winters. Flora and fauna Fuxian Lake is known for its unique fauna, including many endemic species. However, its relative isolation makes it vulnerable to biological invasions and pollution. Together with other Yunnan lakes (Dian, Qilu, Yangzong, Xingyun, and Yilong), Fuxian is recognized as an ecoregion. Fuxian is one of three major Yunnan lakes with a high number of endemics, the others being Dian (Dianchi) and Erhai.Wang, Wang, Li, Du, Yang, Lassoie, and Hassan (2013). ...

Yunnan Province
Yunnan , () is a landlocked province in the southwest of the People's Republic of China. The province spans approximately and has a population of 48.3 million (as of 2018). The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, autonomous regions of Guangxi, and Tibet Autonomous Region, Tibet as well as Southeast Asian countries: Vietnam, Laos, and Myanmar.

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...

IUCN
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yilong Lake
Yilong Lake () is a large freshwater lake located in Shiping County, Honghe Prefecture, Yunnan province, southwestern China. The lake has a surface area of approximately and is particularly notable for its scenery, including the colorful lotus flowers that bloom on its surface. It is located about east of the county seat. The people who live in the vicinity of the lake are largely of the Yi ethnic group. As of the spring of 2013 a severe drought had resulted in substantial lowering of the water level. The lake is one of the most-visited destinations in the Yunnan-Guizhou Plateau. It used to be called Yulong Lake, an allusion to the Yulong Mountain that lies to the lake's south. The change of name has mythological reasons. It is believed that in 1629, the dragon believed to live in the lake ascended to heaven in broad daylight, prompting the change in the lake's name. Not much is known about how the lake formed. Records tell that the lake formed during the Qin and Han dynastie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
