Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria. The 313 members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Their ease of culture in vitro and availability of an increasing number of Pseudomonas strain genome sequences has made the genus an excellent focus for scientific research; the best studied species include P. aeruginosa in its role as an opportunistic human pathogen, the plant pathogen P. syringae, the soil bacterium P. putida, and the plant growth-promoting P. fluorescens, P. lini, P. migulae, and P. graminis.
The history of the People's Republic of China details the history of mainland China since 1 October 1949, when CCP chairman Mao Zedong proclaimed the People's Republic of China (PRC) from atop Tiananmen, after a near complete victory (1949) by the Chinese Communist Party (CCP) in the Chinese Civil War. The PRC is the most recent political entity to govern mainland China, preceded by the Republic of China and thousands of years of monarchical dynasties. The paramount leaders have been Mao Zedong (1949–1976); Hua Guofeng (1976–1978); Deng Xiaoping (1978–1989); Jiang Zemin (1989–2002); Hu Jintao (2002–2012); and Xi Jinping.
Oleksandr Prokopovych Markevych was a Ukrainian zoologist, and a prolific helminthologist and copepodologist. He was professor and an Academician of the National Academy of Sciences of Ukraine.
A protist is any eukaryotic organism that is not an animal, plant, or fungus. The protists do not form a natural group, or clade, since they exclude certain eukaryotes with whom they share a common ancestor; but, like algae or invertebrates, the grouping is used for convenience. In some systems of biological classification, such as the popular five-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues". In the 21st century, the classification shifted toward a two-kingdom system of protists: Chromista and Protozoa.
Gyrodactylus arcuatoides is an ectoparasite. It was found on the sand goby in European coastal waters.
Gyrodactylus branchialis is a species of monogenean ectoparasites. It was found in Pomatoschistus microps in European coastal waters.
Gyrodactylidae is a family of flatworms in the order Gyrodactylidea.
Alexandr Vladimirovich Gussev, sometimes spelled Gusev in the literature, was a Russian helminthologist specialist of monogeneans.
Scientific ice drilling began in 1840, when Louis Agassiz attempted to drill through the Unteraargletscher in the Alps. Rotary drills were first used to drill in ice in the 1890s, and thermal drilling, with a heated drillhead, began to be used in the 1940s. Ice coring began in the 1950s, with the International Geophysical Year at the end of the decade bringing increased ice drilling activity. In 1966, the Greenland ice sheet was penetrated for the first time with a 1,388 m hole reaching bedrock, using a combination of thermal and electromechanical drilling. Major projects over the following decades brought cores from deep holes in the Greenland and Antarctic ice sheets.
Ancyrocephalidae is a family of monogenean flatworms. The family is considered as a "temporary name" in WorMS but includes a large number of genera and species.
