Narceus Americanus
''Narceus americanus'' is a large millipede of eastern North America. Common names include American giant millipede, worm millipede, and iron worm. It inhabits the eastern seaboard of North America west to Georgetown, Texas, north of the Ottine wetlands. It has a nearly cylindrical gray body, reaching a length of . They can be commonly found in or under decaying logs from March to October. When threatened, they sometimes curl up or release a noxious liquid that contains large amounts of benzoquinones which can cause dermatological burns. This fluid may irritate eyes or skin. Many other millipedes secrete hydrogen cyanide, and while there have also been claims that ''N. americanus'' releases hydrogen cyanide, they are unsubstantiated. They do, however, excrete a substance that causes a temporary, non-harmful discoloration of the skin known as millipede burn. Ecology and behavior Diet ''N. americanus'' are detritivores, primarily consuming decaying wood and leaf litter. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palisot De Beauvois
Ambroise Marie François Joseph Palisot, Baron de Beauvois (27 July 1752, in Arras – 21 January 1820, in Paris) was a French naturalist and zoologist. Palisot collected insects in Oware, Benin, Saint Domingue, and the United States, from 1786 to 1797. Trained as a botanist, Palisot published a significant entomological paper entitled, "Insectes Receuillis en Afrique et en Amerique". Together with Frederick Valentine Melsheimer, he was one of the first entomologists to collect and describe American insects. He described many common insects and suggested an ordinal classification of insects. He described many Scarabaeidae as well as illustrating them for the first time. The study included 39 '' Scarabaeus'' species, 17 '' Copris'' species, 7 '' Trox'' species, 4 '' Cetonia'' and 4 '' Trichius'' species. Familiar beetles such as '' Canthon viridis'', '' Macrodactylus angustatus'' and '' Osmoderma scabra'' were first described by him. Many of the specimens that were labelled fro ...

Millipede
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from the Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of ''Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fungi or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of North Carolina Press
The University of North Carolina Press (or UNC Press), founded in 1922, is a university press that is part of the University of North Carolina. It was the first university press founded in the Southern United States. It is a member of the Association of University Presses (AUPresses) and publishes both scholarly and general-interest books and journals. According to its website, UNC Press advances "the University of North Carolina's triple mission of teaching, research, and public service by publishing first-rate books and journals for students, scholars, and general readers." It receives support from the state of North Carolina and the contributions of individual and institutional donors who created its endowment. Its headquarters are located in Chapel Hill.

1,4-Benzoquinone
1,4-Benzoquinone, commonly known as ''para''-quinone, is a chemical compound with the formula C6H4O2. In a pure state, it forms bright-yellow crystals with a characteristic irritating odor, resembling that of chlorine, bleach, and hot plastic or formaldehyde. This six-membered ring compound is the oxidized derivative of 1,4-hydroquinone. The molecule is multifunctional: it exhibits properties of a ketone, being able to form oximes; an oxidant, forming the dihydroxy derivative; and an alkene, undergoing addition reactions, especially those typical for α,β-unsaturated ketones. 1,4-Benzoquinone is sensitive toward both strong mineral acids and alkali, which cause condensation and decomposition of the compound. Preparation 1,4-Benzoquinone is prepared industrially by oxidation of hydroquinone, which can be obtained by several routes. One route involves oxidation of diisopropylbenzene and the Hock rearrangement. The net reaction can be represented as follows: :C6H4(CHMe2)2 + 3 ...

Hydrogen Cyanide
Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the formula HCN and structure . It is a colorless, extremely poisonous, and flammable liquid that boils slightly above room temperature, at . HCN is produced on an industrial scale and is a highly valued precursor to many chemical compounds ranging from polymers to pharmaceuticals. Large-scale applications are for the production of potassium cyanide and adiponitrile, used in mining and plastics, respectively. It is more toxic than solid cyanide compounds due to its volatile nature. Structure and general properties Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a p''K''a of 9.2. It partially ionizes in water solution to give the cyanide anion, CN−. A solution of hydrogen cyanide in water, represented as HCN, is called ''hydrocyanic acid''. The salts of the cyanide ani ...

Millipede Burn
Millipede burns are a cutaneous condition caused by certain millipedes that secrete a toxic liquid that causes a brownish pigmentation and/or burns when it comes into contact with the skin. Some millipedes produce quinones in their defensive secretions, which have been reported to cause brown staining of the skin.

Spermatophore
A spermatophore or sperm ampulla is a capsule or mass containing spermatozoa created by males of various animal species, especially salamanders and arthropods, and transferred in entirety to the female's ovipore during reproduction. Spermatophores may additionally contain nourishment for the female, in which case it is called a nuptial gift, as in the instance of bush crickets. In the case of the toxic moth ''Utetheisa ornatrix'', the spermatophore includes sperm, nutrients, and pyrrolizidine alkaloids which prevent predation because it is poisonous to most organisms. However, in some species such as the Edith's checkerspot butterfly, the "gift" provides little nutrient value. The weight of the spermatophore transferred at mating has little effect on female reproductive output. Arthropods Spermatophores are the norm in arachnids and several soil arthropods. In various insects, such as bush crickets, the spermatophore is often surrounded by a proteinaceous spermatophylax. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
