Mites
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive '' Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of ara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oribatida
Oribatida (formerly Cryptostigmata), also known as oribatid mites, moss mites or beetle mites, are an order of mites, in the "chewing Acariformes" clade Sarcoptiformes. They range in size from . There are currently 12,000 species that have been identified, but researchers estimate that there may be anywhere from 60,000 to 120,000 total species. Oribatid mites are by far the most prevalent of all arthropods in forest soils, and are essential for breaking down organic detritus and distributing fungi. Oribatid mites generally have low metabolic rates, slow development and low fecundity. Species are iteroparous with adults living a relatively long time; for example, estimates of development time from egg to adult vary from several months to two years in temperate forest soils. Oribatid mites have six active instars: prelarva, larva, three nymphal instars and the adult. All these stages after the prelarva feed on a wide variety of material including living and dead plant and fungal m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amerus (mite)
Amerus (also Aluredus, Annuerus, Aumerus) was a 13th-century English music theorist who lived in Italy. Amerus worked under Cardinal Ottobono Fieschi, who later became Pope Adrian V, and wrote his only known work, ''Practica artis musicae'', while in Fieschi's employ. It is thought that he wrote the text in 1271 at Viterbo, where the papal conclave was held. ''Practica artis musicae'' is an instruction treatise for boys, which explains contemporaneous musical notation systems. The bulk of the work is an explanation of the tonary system as it was used in French, English, and Italian churches. The treatise also discusses the composition of polyphony, which is believed to be the first surviving treatise from Italy to use rhythmic notation. Amerus discusses the ''longa'', ''brevis'', and ''semibrevis'', assigning them in groups of two (rather than three). The work is preserved in the Bamberg Codex, among other places. References *F.
