Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.

Arachnid
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult inse ...

Trombidiformes
The Trombidiformes are a large, diverse order of mites. Taxonomy In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata. The group has few synapomorphies by which it can be defined, unlike the other major group of acariform mites, Sarcoptiformes. Its members include medically important mites (such as ''Demodex'', the chiggers, and scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae). The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes. The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species. In the 2011 revised classification, the order now contains 151 families, 2235 genera and 25,821 species, and there were another 10 species with 24 species that present only as fossils. These 151 ...

Tydeidae
Tydeidae is a family of acariform mites. As of 2016, it contained over 300 species in three subfamilies, though more species have been discovered since then. These mites live in a wide range of habitats and there are predatory, fungivorous and scavenging species. Description Tydeidae are soft-bodied mites with an idiosoma that is striated, reticulated or a combination of both. They have two bothridial setae. The chelicerae have fused bases, a movable digit that is relatively short and needle-like, and a fixed digit that is reduced. They may have two or three eyes, though some species are blind. Of the three subfamilies, Pretydeinae has no setae on the genu of legs II, III or IV, and the palptarsus has a triple eupathidium at the end. The other two subfamilies have one or two setae (Tydeinae) or three setae (Australotydeinae) on the genu of leg II, and the palptarsus ends in a double or triple eupathidium.

Mite
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 Predation, predators or Parasitism, 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 disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Domestica
''Prunus domestica'', the European plum is a species of flowering plant in the family Rosaceae. A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species. The greengages and damsons also belong to subspecies of ''P. domestica''. Its hybrid parentage was believed to be ''Prunus spinosa'' and '' P. cerasifera''; however recent cytogenetic evidence seem to implicate 2×, 4×, 6× ''P. cerasifera'' as the sole wild stock from which the cultivated 6× ''P. domestica'' could have evolved. Description Typically it forms a large shrub or a small tree. It may be somewhat thorny, with white blossom, borne in early spring. The oval or spherical fruit varies in size, but can be up to across. The pulp is usually sweet, but some varieties are sour. Like all ''Prunus'' fruits, it contains a single large seed, usually called a stone, which is discarded when eating. Taxonomy Subspecies Cull ...

Psidium Guajava
''Psidium guajava'', the common guava, yellow guava, lemon guava, or apple guava is an evergreen shrub or small tree native to the Caribbean, Central America and South America. It is easily pollinated by insects; when cultivated, it is pollinated mainly by the common honey bee, ''Apis mellifera''. Overview Widely cultivated in tropical and subtropical regions around the world, guava fruits can range in size from as small as an apricot to as large as a grapefruit. Various cultivars have white, pink, or red flesh; a few varieties feature red (instead of green or yellow) skin. When cultivated from seed, guavas are notable for their extremely slow growth rate for several months, before a very rapid acceleration in growth rate takes over. From seed, common guavas may bloom and set fruit in as few as two years or as many as eight. Cuttings, grafting, and air layering are more commonly used as a propagation method in commercial groves. Highly adaptable, guavas can be easily grown a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potchefstroom
Potchefstroom (, colloquially known as Potch) is an academic city in the North West Province of South Africa. It hosts the Potchefstroom Campus of the North-West University. Potchefstroom is on the Mooi Rivier (Afrikaans for "pretty river"), roughly west-southwest of Johannesburg and east-northeast of Klerksdorp. Etymology Several theories exist about the origin of the city's name. According to one theory, it originates from ''Potgieter'' + ''Chef'' + ''stroom'' (referring to Voortrekker leader and town founder Andries Potgieter; "chef" indicates the leader of the Voortrekkers, and "stroom" refers to the Mooi River). Geoffrey Jenkins writes, "Others however, attribute the name as having come from the word 'Potscherf', meaning a shard of a broken pot, due to the cracks that appear in the soil of the Mooi River Valley during drought resembling a broken pot". M. L. Fick suggests that Potchefstroom developed from the abbreviation of "Potgieterstroom" to "Potgerstroom", whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
