Armand Borel was a Swiss mathematician, born in La Chaux-de-Fonds, and was a permanent professor at the Institute for Advanced Study in Princeton, New Jersey, United States from 1957 to 1993. He worked in algebraic topology, in the theory of Lie groups, and was one of the creators of the contemporary theory of linear algebraic groups.
Serge Lang was a French-American mathematician and activist who taught at Yale University for most of his career. He is known for his work in number theory and for his mathematics textbooks, including the influential Algebra. He received the Frank Nelson Cole Prize in 1960 and was a member of the Bourbaki group.
Neal I. Koblitz is a Professor of Mathematics at the University of Washington. He is also an adjunct professor with the Centre for Applied Cryptographic Research at the University of Waterloo. He is the creator of hyperelliptic curve cryptography and the independent co-creator of elliptic curve cryptography.
Root-knot nematodes are plant-parasitic nematodes from the genus Meloidogyne. They exist in soil in areas with hot climates or short winters. About 2000 plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and nutrients. Infection of young plants may be lethal, while infection of mature plants causes decreased yield.
Richard William Timm was a Catholic Priest, educator, zoologist, and development worker. He was the Superior of the Congregation of Holy Cross in Dhaka and a member of the Sacred Heart of Jesus Province. He was also one of the founders of Notre Dame College in Dhaka, Bangladesh. He was the 6th principal of Notre Dame College.
Armand Marie Leroi is a New Zealand-born Dutch author, broadcaster, and professor of evolutionary developmental biology at Imperial College in London. He received the Guardian First Book Award in 2004 for his book Mutants: On Genetic Variety and the Human Body. He has presented scientific documentaries on Channel 4 such as Alien Worlds (2005) and What Makes Us Human (2006), and BBC Four such as What Darwin Didn't Know (2009), Aristotle's Lagoon (2010), and Secret Science of Pop (2012).
Oncholaimoidea is a superfamily of nematodes. It is the only superfamily in the monotypic suborder Oncholaimina.
Aphelenchoides ritzemabosi is a plant pathogenic nematode. It was first scientifically described in 1890 in England. This nematode has a wide host range. Among the most important species affected are Chrysanthemums and strawberries. A. ritzemabosi is a migratory foliar feeding nematode. It can feed both ectoparasitically and endoparasitically, with the later causing the most significant damage. When adequate moisture is present, this nematode enters the leaves and feeds from inside the tissue. Typical damage is characterized by necrotic zones between the veins of the leaves. Its lifecycle is short; only ten days from egg to mature adult. A single female can lay as many as 3,500 eggs. This pest can be difficult to control. Host plant resistance, hot water treatments, and predatory mites are recommended.
Xiphinema americanum, the American dagger nematode, is a species of plant pathogenic nematodes. It is one of many species that belongs to the genus Xiphinema. It was first described by N. A. Cobb in 1913, who found it on both sides of the United States on the roots of grass, corn, and citrus trees. Not only is Xiphinema americanum known to vector plant viruses, but also X. americanum has been referred to as "the most destructive plant parasitic nematode in America", and one of the four major nematode pests in the Southeastern United States.
Anguina is a genus of plant pathogenic nematodes.
Anguina amsinckiae is a plant pathogenic nematode, which attacks the weed called fiddleneck.
The nematodes, roundworms or eelworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a broad range of environments. Most species are free-living, feeding on microorganisms, but there are many that are parasitic. The parasitic worms (helminths) are the cause of soil-transmitted helminthiases.
Michel Luc was a French zoologist (nematologist) and one of the founding fathers of the field of plant-nematology. He spent his career with ORSTOM, now IRD. He created the first French nematology laboratory in the ORSTOM research station of Adiopodoumé, near Abidjan in 1955, and a second nematology lab at Dakar Bel-Air (Senegal) in 1969. In 1978, he launched the Revue de Nématologie that fused with Nematologica in 1999 to become Nematology, currently the leading nematology journal in the field. He was a world-renowned authority on nematode taxonomy.
A megadrile is a kind of worm, a mostly terrestrial oligochaete. Megadriles are placed within the superorder Megadrilacea, and include Moniligastrida and Lumbricina.
Microdriles are mostly aquatic or semi-terrestrial oligochaetes.
Root-gall nematodes are plant-parasitic nematodes from the genus Subanguina that affect grasses, including cereals, and some other plants, such as mugwort. They are distinct from the Root-knot nematodes which are from the genus Meloidogyne. So far around twenty-five separate species of Subanguina have been identified, although the most well-known and type species is Subanguina radicicola.
Oligosaprobes are organisms that inhabit clean water or water that is only slightly polluted by organic matter. Oxidation processes predominate in such waters owing to an excess of dissolved oxygen. Nitrates are among the nitrogen compounds present; there is little carbonic acid and no hydrogen sulfide. Oligosaprobic environments are aquatic environments rich in dissolved oxygen and (relatively) free from decayed organic matter.
Chronogaster elegans is a species of nematodes. It is found in fresh water in the USA.
The subcapitulum, also known as infracapitulum, hypognathum or hipognatum, refers to the ventral part of the gnathosoma or the fusion of the palpal coxae and the labrum complex present in some arthropods on which the mouth, pedipalps, mouthparts and pharynx are generally located. It is delimited by the subcapitular apodeme, which separates it from the cheliceral frame.
Benjamin Goodwin Chitwood was an American zoologist and pioneer in nematology. He published extensively and broadly in the field of nematology. An Introduction to Nematology, published with his wife May Belle Hutson Chitwood, was a major contribution to the field. Chitwood identified the species Globodera rostochiensis on Long Island in 1941 and as part of his work on higher classification revised the taxonomy of the root-knot nematode Meloidogyne incognita in 1949. This led to changes in research and control strategies for it. He served as president of the Helminthological Society of Washington in 1949 and was made a Life Member of the Society in 1968.
