Luc, M
Michel Luc (7 February 1927 – 18 January 2010) was a French zoologist (nematologist) and one of the founding fathers of the field of plant- nematology. He spent his career with ORSTOM (''Office de la Recherche Scientifique et Technique Outre-Mer''), now IRD ('' Institut de recherche pour le développement''). He created the first French nematology laboratory in the ORSTOM research station of Adiopodoumé, near Abidjan (Ivory Coast) in 1955, and a second nematology lab at Dakar Bel-Air (Senegal) in 1969. In 1978, he launched the ''Revue de Nématologie'' (soon renamed ''Fundamental and Applied Nematology'') 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. Biography Michel Luc was born on 7 February 1927 in Tunis (Tunisia). From 1945, on, he studied biology in Paris at the Sorbonne, where he attended classes delivered by biologists such as Georges Mange ...

Berdon
Berdon syndrome, also called Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIH syndrome), is an autosomal recessive fatal genetic disorder affecting newborns. In a 2011 study of 227 children with the syndrome, "the oldest survivor as24 years old." '' The Ann Arbor News'' reported a five year old survivor at the end of 2015. It is more prevalent in females (7 females to 3 males) and is characterized by constipation and urinary retention, microcolon, giant bladder (megacystis), intestinal hypoperistalsis, hydronephrosis and dilated small bowel. The pathological findings consist of an abundance of ganglion cells in both dilated and narrow areas of the intestine. It is a familial disturbance of unknown cause. Walter Berdon ''et al.'' in 1976 first described the condition in five female infants, two of whom were sisters. All had marked dilatation of the bladder and some had hydronephrosis and the external appearance of prune belly. The infants also had microcolon an ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter ('' Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Heterodera
''Heterodera'' is a genus of nematodes in the family Heteroderidae. Members of the genus are obligate Parasitism, parasites and different species attack different crops, often causing great economic damage. The genus is unique among nematode genera because of the ability of the female to transform into a tough, brown, cyst which protects the Egg (biology), eggs which have been formed within her body. The name heterodera "refers to the different 'skins' of female and cyst."Tylenchida: Parasites of Plants and Insects, 2nd ed., by Mohammad Rafiq Siddiqi Diversity The following is a list of taxa in the genus ''Heterodera'': * ''Heterodera amygdali'' * ''Heterodera arenaria'' * ''Heterodera aucklandica'' * ''Heterodera avenae'' * ''Heterodera bergeniae'' * ''Heterodera bifenestra'' * ''Heterodera cacti'' * ''Heterodera cajani'' * ''Heterodera canadensis'' * ''Heterodera cardiolata'' * ''Heterodera carotae'' * ''Heterodera ciceri'' * ''Heterodera cruciferae'' * ''Heterodera delvii'' * ' ...

Plant Pathogenic Nematodes
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abili ...

Nematodes Described In 1961
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant- parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.
