Migratory Locust
The migratory locust (''Locusta migratoria'') is the most widespread locust species, and the only species in the genus ''Locusta''. It occurs throughout Africa, Asia, Australia and New Zealand. It used to be common in Europe but has now become rare there. Because of the vast geographic area it occupies, which comprises many different ecological zones, numerous subspecies have been described. However, not all experts agree on the validity of some of these subspecies. Many other species of grasshopper with gregarious and possibly migratory behaviour are referred to as 'locusts' in the vernacular, including the widely distributed desert locust. At 6.5 Gbp, the migratory locust possesses one of the largest known insect genomes.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin ''kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac- colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edible Insects
Insects as food or edible insects are insect species used for human consumption. More than 2,000 insects species worldwide are considered edible. However, a much smaller number is discussed for industrialized mass production and partly regionally authorized for use in food. Common forms of consumption are whole insects on the one hand, and pulverized insects that are used as an ingredient in dishes or in processed food products such as burger patties, pasta, or snacks, on the other hand. Edible insects Frequently consumed insect species Estimates of numbers of edible insect species consumed globally range from 1,000 to 2,000. These species include 235 butterflies and moths, 344 beetles, 313 ants, bees and wasps, 239 grasshoppers, crickets and cockroaches, 39 termites, and 20 dragonflies, as well as cicadas. It is estimated that more than 2 billion people eat insects daily. Which species are consumed varies by region due to differences in environment, ecosystems, and clima ...

Locusta Migratoria Migratorioides
''Locusta migratoria migratorioides'', commonly known as the African migratory locust, is a subspecies of the migratory locust family Acrididae. It occurs in most of Africa south of the Sahara Desert, but its main breeding ground, and the original source of most plagues, is on the floodplains of the Niger River in West Africa. Much of the time, this locust adopts a solitary lifestyle, but under certain conditions, it becomes gregarious; the young nymphs, known as hoppers, form bands that move together and the adult insects form swarms that may reach plague proportions. Plagues of this locust took place from 1891 to 1903 and again from 1928 to 1941. After many years without outbreaks of the insects, further plagues occurred in the last two decades of the 20th century. Description The African migratory locust has two phases, a solitary one, where the insects behave independently, and a gregarious phase, where they gather together and act as a cohesive unit. Adult insects differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Distribution Modelling
Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping uses computer algorithms to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most often climate data (e.g. temperature, precipitation), but can include other variables such as soil type, water depth, and land cover. SDMs are used in several research areas in conservation biology, ecology and evolution. These models can be used to understand how environmental conditions influence the occurrence or abundance of a species, and for predictive purposes (ecological forecasting). Predictions from an SDM may be of a species’ future distribution under climate change, a species’ past distribution in order to assess evolutionary relationships, or the potential future distribution of an invasive species. Predictions of current and/or f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diffusion Potential
Liquid junction potential (shortly LJP) occurs when two solutions of electrolytes of different concentrations are in contact with each other. The more concentrated solution will have a tendency to diffuse into the comparatively less concentrated one. The rate of diffusion of each ion will be roughly proportional to its speed in an electric field, or their ion mobility. If the anions diffuse more rapidly than the cations, they will diffuse ahead into the dilute solution, leaving the latter negatively charged and the concentrated solution positively charged. This will result in an electrical double layer of positive and negative charges at the junction of the two solutions. Thus at the point of junction, a potential difference will develop because of the ionic transfer. This potential is called liquid junction potential or diffusion potential which is non-equilibrium potential. The magnitude of the potential depends on the relative speeds of the 'ions' movement.
