Mesoplodont whales are 15 species of toothed whale in the genus Mesoplodon, making it the largest genus in the cetacean order. Two species were described as recently as 1991 (pygmy beaked whale) and 2002 (Perrin's beaked whale), and marine biologists predict the discovery of more species in the future. They are the most poorly known group of large mammals. The generic name "mesoplodon" comes from the Greek meso- (middle) - hopla (arms) - odon (teeth), and may be translated as 'armed with a tooth in the centre of the jaw'.

A Mesophotic coral reef, from meso meaning middle and photic meaning light, is characterised by the presence of both light dependent coral and algae, and organisms that can be found in water with low light penetration. They normally grow between 30 to 40 metres (130 ft) and up to 150 metres (490 ft) in tropical and subtropical water. The most common species at the mesophotic level are corals, sponges and algae. The corals ranges can overlap with Deep-water coral but are distinguished by the presence of zooxanthellae and their requirement for light. They can also be thought of as part of shallow water coral ecosystems, and a crossover of coral species between the two is common. It is thought that these corals could be used as sources for reseeding shallow water coral species. The oldest kno

Mesonauta, the flag cichlids, is a small genus of cichlids native to the Amazon, Orinoco, Essequibo, Paraná and Paraguay basins in South America. Mesonauta is included in the subfamily Cichlasomatinae. They occur in various freshwater habitats such as streams and lakes, especially in areas with little water movement and aquatic vegetation. They are generally found in small groups that stay near the water surface. To avoid predators, adults may jump out of the water and juveniles mimic leaves. Some species are popular in the fishkeeping hobby and are frequently kept in aquariums. These have traditionally been referred to as M. festivus, but following taxonomic reviews of the genus in 1991 and 1998, the species most often seen in the aquarium trade are M. guyanae, M. insignis and M. mirificus. The species are similar in general appearance, but they have different distributions and can be separated by the bars they show on the body when stressed or excited (very faint when relaxed).

La Mesopotamia or Región Mesopotámica is the humid and verdant area of north-east Argentina, comprising the provinces of Misiones, Entre Ríos and Corrientes. The landscape and its characteristics are dominated by two rivers, the Paraná and the Uruguay. When Spanish settlers came to the area, the two parallel rivers and the lush area between them drew comparisons to Mesopotamia (Greek: Μεσοποταμία "land between rivers") in modern-day Iraq, and it was decided to name the Argentine region for the Iraqi region. The region shares many of its ecological features with neighboring regions of Argentina and with parts of Brazil, Paraguay, and Uruguay. Mesopotamia has some of the most popular tourist attractions in Argentina, mainly the Iguazú Falls, the Iguazú National Park and the Jesuit mission stations in Misiones. The Iberá Wetlands in Corrientes are an extensive area of flooded forest similar to Brazil's Pantanal. The region is part of the Brazilian central plateau. The whole region has high rainfall, particularly in August and September, up to 2,000 mm annually. Misiones, in the northern part of Mesopotamia, is largely covered by subtropical forest, with caiman, toucans and monkeys. Fast decomposition of organic matter gives the area a red soil with only a thin fertile layer that can easily be washed away. Corrientes is marshy and wooded, with low hills. Entre Ríos is covered with fertile pasture land stretching into Uruguay. The flora of Mesopotamia includes the yatay palm (Syagrus yatay, Butia yatay), which is a protected species in the El Palmar National Park, and the Araucaria angustifolia (Paraná pine tree). Tree ferns, orchids and large trees can also be found. Yerba mate (Ilex paraguariensis) is grown largely in Mesopotamia; 1,800 square kilometres of Misiones are devoted to its production. The region is also important for cattle and sheep, poultry, linseed, tobacco, citrus and rice. Gualeguaychú in Entre Ríos is popular for its carnival at the beginning of Lent. Corrientes is also known for its carnival celebrations and is a centre of music and festivals generally: the chamamé music style has recently seen a resurgence in popularity. The region called Litoral (Spanish for coastal) consists of the Mesopotamia and the provinces of Chaco, Formosa and Santa Fe.

Mesonoemacheilus is a genus of stone loach endemic to India.

In meteorology (and climatology), a mesonet, portmanteau of mesoscale network, is a network of (typically) automated weather and environmental monitoring stations designed to observe mesoscale meteorological phenomena. Dry lines, squall lines, and sea breezes are examples of phenomena that can be observed by mesonets. Due to the space and time scales associated with mesoscale phenomena, weather stations comprising a mesonet will be spaced closer together and report more frequently than synoptic scale observing networks, such as ASOS. The term mesonet refers to the collective group of these weather stations, and are typically owned and operated by a common entity. Mesonets usually record in situ surface weather observations but some involve other observation platforms, particularly vertical profiles of the planetary boundary layer (PBL). The distinguishing features that classify a network of weather stations as a mesonet are station density and temporal resolution. Depending upon the phenomena meant to be observed, mesonet stations utilize a spatial spacing of 1 to 40 kilometres (0.62 to 24.85 mi) and report conditions every 1 to 15 minutes. Micronets (see microscale and ), such as in metropolitan areas such as Oklahoma City, St. Louis, and Birmingham UK, may be even denser in spatial resolution.

Mesonychia ("middle claws") is an extinct taxon of small- to large-sized carnivorous ungulates related to the cetartiodactyls. Mesonychids first appeared in the early Paleocene, went into a sharp decline at the end of the Eocene, and died out entirely when the last genus, Mongolestes, became extinct in the early Oligocene. in Asia, the record of their history suggests they grew gradually larger and more predatory over time, then shifted to scavenging and bone-crushing lifestyles before the group became extinct. Mesonychids probably originated in China, where the most primitive mesonychid, Yangtanglestes, is known from the early Paleocene. They were also most diverse in Asia, where they occur in all major Paleocene faunas. Since other predators, such as creodonts and Carnivora, were either rare or absent in these animal communities, mesonychids most likely dominated the large predator niche in the Paleocene of Eastern Asia. One genus, Dissacus, had successfully spread to Europe and North America by the early Paleocene. Dissacus was a jackal-sized predator that has been found all over the Northern Hemisphere, but species of a closely related or identical genus, Ankalagon, from the early to middle Paleocene of New Mexico, were far larger, growing to the size of a bear. A later genus, Pachyaena, entered North America by the earliest Eocene, where it evolved into species that were at least as large. Mesonychids in North America were by far the largest predatory mammals during the early Paleocene to middle Eocene.

Mesopotamia is a narrow ait (about 800 yards by 30 yards) that forms part of the University Parks in Oxford, England. It lies between the upper and lower levels of the River Cherwell which are partly interspersed with the Thames. The name Mesopotamia in Greek means "between the rivers", and is shared with an area between the Tigris and Euphrates rivers in present-day Iraq. The land was purchased by the University of Oxford during the expansion of the Oxford University Parks between 1860 and 1865. A footpath, Mesopotamia Walk, laid out in 1865 runs along the centre of the spur to Kings Mill. The Domesday Book records a watermill on this site and milling continued until 1825; one level of the river was once the mill stream. From 1914, attempts were made to introduce wild ducks and geese to the area, which proved fruitless due to a predatory otter population. Until 1926, a ferry operated from a point halfway along the Walk, when it was replaced by a footbridge. Position: grid reference SP525069

A mesoporous material is a material containing pores with diameters between 2 and 50 nm, according to IUPAC nomenclature. For comparison, IUPAC defines microporous material as a material having pores smaller than 2 nm in diameter and macroporous material as a material having pores larger than 50 nm in diameter. Typical mesoporous materials include some kinds of silica and alumina that have similarly-sized mesopores. Mesoporous oxides of niobium, tantalum, titanium, zirconium, cerium and tin have also been reported. However, the flagship of mesoporous materials is mesoporous carbon, which has direct applications in energy storage devices. Mesoporous carbon has porosity within the mesopore range and this significantly increases the specific surface area. An other very common mesoporous material is Activated Carbon which is typically composed of a carbon framework with both mesoporosity and microporosity depending on the conditions under which it was synthesized. According to IUPAC, a mesoporous material can be disordered or ordered in a mesostructure. In crystalline inorganic materials, mesoporous structure noticeably limits the number of lattice units, and this significantly changes the solid-state chemistry. For example, the battery performance of mesoporous electroactive materials is significantly different from that of their bulk structure. A procedure for producing mesoporous materials (silica) was patented around 1970, and methods based on the Stöber process from 1968 were still in use in 2015. It went almost unnoticed and was reproduced in 1997. Mesoporous silica nanoparticles (MSNs) were independently synthesized in 1990 by researchers in Japan. They were later produced also at Mobil Corporation laboratories and named Mobil Crystalline Materials, or MCM-41. The initial synthetic methods did not permit to control the quality of the secondary level of porosity generated. It was only by employing quaternary ammonium cations and silanization agents during the synthesis that the materials exhibited a true level of hierarchical porosity and enhanced textural properties. Since then, research in this field has steadily grown. Notable examples of prospective industrial applications are catalysis, sorption, gas sensing, ion exchange, optics, and photovoltaics. It should be taken into account that this mesoporosity refers to the classification of nanoscale porosity, and mesopores may be defined differently in other contexts; for example, mesopores are defined as cavities with sizes in the range 30 μm–75 μm in the context of porous aggregations such as soil.

Mesoplanets are planetary bodies with sizes smaller than Mercury but larger than Ceres. The term was coined by Isaac Asimov. Assuming size is defined in relation to equatorial radius, mesoplanets should be approximately 500 km to 2,500 km in radius. The term was coined in Asimov's essay "What's in a Name?", which first appeared in The Los Angeles Times in the late 1980s and was reprinted in his 1990 book ; the term was later revisited in his essay, "The Incredible Shrinking Planet" which appeared first in The Magazine of Fantasy and Science Fiction and then in the anthology The Relativity of Wrong (1988). Asimov noted that the Solar System has a large number of planetary bodies (as opposed to the Sun and natural satellites) and stated that lines dividing "major planets" from minor planets were necessarily arbitrary. Asimov then pointed out that there was a large gap in size between Mercury, the smallest planetary body that was considered to be undoubtedly a major planet, and Ceres, the largest planetary body that was considered to be undoubtedly a minor planet. Only one planetary body known at the time, Pluto, fell within the gap. Rather than arbitrarily decide whether Pluto belonged with the major planets or the minor planets, Asimov suggested that any planetary body that fell within the size gap between Mercury and Ceres be called a mesoplanet, because mesos means "middle" in Greek.

Mesopotamian Iraqi is an Aramaic Syriac substrate, and also shares significant influences from ancient Mesopotamian languages of Akkadian, Sumerian and Babylonian, as well as Persian, Turkish, Kurdish and Greek. Mesopotamian Arabic is said to be the most Aramaic-Syriac influenced dialect of Arabic, due to Armaic-Syriac having originated in Mesopotamia, and spread throughout the Middle East (Fertile Crescent) during the Neo-Assyrian period, eventually becoming the lingua franca of the entire region before Islam.[6][7][8] Iraqi Arabs and Assyrians are the largest Semitic peoples in Iraq, sharing significant similarities in language between Mesopotamian Arabic and Syriac.

Mesopotamia is an EP by new wave band the B-52's. It was produced by David Byrne of Talking Heads and was originally planned to be the band's third studio album. Due to conflicts with Byrne and record label pressure, recording sessions were aborted prematurely and only six of ten songs to be completed were released as a shorter than originally intended LP. The record was distributed as a 12" EP by Warner Bros. in the US and by Island Records on vinyl and cassette in the UK and other non-US markets. Mesopotamia is considered a departure in style for the B-52's; Byrne and the band added plenty of additional instruments, vocal overdubs, horns, synthesizers, layered percussion and an altogether richer sound. A larger emphasis was placed on production after the raw sound of their debut album The B-52's and the slightly more polished sound of their second album, Wild Planet.

A mesoporous material is a material containing pores with diameters between 2 and 50 nm, according to IUPAC nomenclature. For comparison, IUPAC defines microporous material as a material having pores smaller than 2 nm in diameter and macroporous material as a material having pores larger than 50 nm in diameter. Since then, research in this field has steadily grown. Notable examples of prospective industrial applications are catalysis, sorption, gas sensing, ion exchange, optics, and photovoltaics.

Mesonephric tubules are genital ridges that are next to the mesonephros. In males, some of the mesonephric kidney tubules, instead of being used to filter blood like the rest, "grow" over to the developing testes, penetrate them, and become connected to the seminiferous tubules of the testes. They also form the epididymis and the paradidymis. The sperm differentiate inside the seminiferous tubules, then swim down these tubes, then through these special mesonephric tubules, and go down inside Wolffian duct, to the coelom and finally to the organ the animal uses to transport sperm into females.

Mesomys is a genus of South American spiny rats in the family Echimyidae. The genus name Mesomys derives from the two ancient greek words μέσος (mésos), meaning "middle of, between", and μῦς (mûs), meaning "mouse, rat". It refers to the fact that this rodent — literally the "middle mouse" — has been considered as an intermediate form related both to mice and jumping rats.

Mesophytes are terrestrial plants which are neither adapted to particularly dry nor particularly wet environments. An example of a mesophytic habitat would be a rural temperate meadow, which might contain goldenrod, clover, oxeye daisy, and Rosa multiflora. Mesophytes prefer soil and air of moderate humidity and avoid soil with standing water or containing a great abundance of salts. They make up the largest ecological group of terrestrial plants, and usually grow under moderate to hot and humid climatic regions.

Mesonacis is an extinct genus of trilobite that lived during the Botomian, found in North-America (excluding Greenland), and the United Kingdom (North-Western Scotland). Some of the species now regarded part of Mesonacis, have previously been assigned to Angustolenellus or Olenellus (Angustolenellus). Angustolenellus is now regarded a junior synonym of Mesonacis.

Mesopic vision is a combination of photopic vision and scotopic vision in low but not quite dark lighting situations. Mesopic light levels range from luminances of approximately 0.001 to 3 cd m−2. Most night-time outdoor and traffic lighting scenarios are in the mesopic range. Humans see differently at different light levels. This is because under high light levels typical during the day (photopic vision), the eye uses cones to process light. Under very low light levels, corresponding to moonless nights without electric lighting (scotopic vision), the eye uses rods to process light. At many night-time levels, a combination of both cones and rods supports vision. Photopic vision facilitates excellent color discrimination ability, whereas colors are indiscriminable under scotopic vision. Mesopic vision falls between these two extremes. In most night-time environments, there is enough ambient light at night to prevent true scotopic vision. In the words of Duco Schreuder, There is not one single luminescence value where photopic vision and scotopic vision meet. To the contrary, there is a wide zone of transition between them. Because it is between photopic and scotopic vision, it is usually called the zone of mesopic vision. The reason that the zone of mesopic vision exists is because the activities of neither cones nor rods is simply switched 'on' or 'off'. There are reasons to believe that the cones and the rods both operate in all luminescence conditions. The effect of switching from cones to rods in processing light is called the "Purkinje shift". During photopic vision, people are most sensitive to light that is greenish-yellow. In scotopic vision, people are more sensitive to light which would appear greenish-blue. The traditional method of measuring light assumes photopic vision and is often a poor predictor of how a person sees at night. Typically research in this area has focused on improving street and outdoor lighting as well as aviation lighting. Prior to 1951, there was no standard for scotopic photometry (light measurement); all measurements were based on the photopic spectral sensitivity function V(λ) which was defined in 1924. In 1951, the International Commission on Illumination (CIE) established the scotopic luminous efficiency function, V'(λ). However, there was still no system of mesopic photometry. This lack of a proper measurement system can lead to difficulties in relating light measurements under mesopic luminances to visibility. Due to this deficiency, the CIE established a special technical committee (TC 1-58) for collecting the results of mesopic visual performance research. Two very similar measurement systems were created to bridge the scotopic and photopic luminous efficiency functions, creating a unified system of photometry. This new measurement has been well-received because the reliance on V(λ) alone for characterizing night-time light illumination can result in the use of more electric energy than might otherwise be needed. The energy-savings potential of using a new way to measure mesopic lighting scenarios is significant; superior performance could in certain cases be achieved with as much as 30 to 50% reduction in the energy use comparing to the high pressure sodium lights.

The gorge of Mesona located in Ierapetra, east of the village of , shortly after the church of Agia Kyriaki. It is relatively a small canyon, and the length is up to 4 km, linking the plateau Thripti the area . The canyon is narrow enough nonetheless but it is passable. It requires a little climbing with ropes and more walking. In the last part of the journey, the morphology of the canyon changes abruptly, as it becomes more narrow and tall walls. Water is only minimal in winter.

Mesopotamia is a narrow ait (about 800 yards by 30 yards) that forms part of the University Parks in Oxford, England. It lies between the upper and lower levels of the River Cherwell which are partly interspersed with the Thames. The name Mesopotamia in Greek means "between the rivers", and is shared with an area between the Tigris and Euphrates rivers in present-day Iraq. The land was purchased by the University of Oxford during the expansion of the Oxford University Parks between 1860 and 1865. A footpath, Mesopotamia Walk, laid out in 1865 runs along the centre of the spur to Kings Mill.

Mesoplanets are planetary bodies with sizes smaller than Mercury but larger than Ceres. The term was coined by Isaac Asimov. Assuming size is defined in relation to equatorial radius, mesoplanets should be approximately 500 km to 2,500 km in radius.

A Mesophotic coral reef, from meso meaning middle and photic meaning light, is characterised by the presence of both light dependent coral and algae, and organisms that can be found in water with low light penetration. They normally grow between 30 to 40 metres (130 ft) and up to 150 metres (490 ft) in tropical and subtropical water. The most common species at the mesophotic level are corals, sponges and algae. The corals ranges can overlap with Deep-water coral but are distinguished by the presence of zooxanthellae and their requirement for light. They can also be thought of as part of shallow water coral ecosystems, and a crossover of coral species between the two is common. It is thought that these corals could be used as sources for reseeding shallow water coral species. The oldest known mesophotic coral ecosystems have been described from the Silurian of Sweden, such ecosystems are also known from Devonian . Oldest scleractinian-dominated mesophotic ecosystems are known from the Triassic

The mesonephros (Greek: middle kidney) is one of three excretory organs that develop in vertebrates. It serves as the main excretory organ of aquatic vertebrates and as a temporary kidney in reptiles, birds, and mammals. The mesonephros is included in the Wolffian body after Caspar Friedrich Wolff who described it in 1759. (The Wolffian body is composed of: mesonephros + paramesonephrotic blastema)

Mesophleps epiochra is a moth of the family Gelechiidae. It is found in Thailand, Papua New Guinea, Australia (Queensland, the Northern Territory, Western Australia), the Solomon Islands, Vanuatu, New Caledonia, Fiji, Western Samoa, Tonga and the Cook Islands. The wingspan is 8–20 mm. The forewings are ochreous yellow, scattered with ochreous brown scales and white-tipped brown scales (especially in the apical half). The larvae feed on Cassia occidentalis, , Sophora tomentosa and Vigna unguiculata. They live in the dry seed pods.

Mesopotamia (Greek: Μεσοποταμία) was the name of a Byzantine theme (a military-civilian province) located in what is today eastern Turkey. It should not be confused with the region of Mesopotamia or with the older Roman and early Byzantine province of Mesopotamia. The Byzantine theme was located between the rivers Arsanias (modern Murat) and Çimisgezek.

It can reach a standard length of 12.1 cm (4.8 in) and is sometimes kept in aquariums. It was generally recognized as the only valid species in the genus Mesonauta until 1991 when a taxonomic review found that five species should be recognized (a sixth was described in 1998). As a consequence aquarium specimens have generally been labelled M. festivus, but this species is seen far less often than some of its relatives, especially M. guyanae, M. insignis and M. mirificus. The other species in the genus have a more northernly range than M. festivus.

Mesophleps safranella is a moth of the family Gelechiidae. It is found in Niger, Benin, Kenya, Malawi, Madagascar and on the Seychelles. The wingspan is 11.5–14 mm.

In physics, a mesophase is a state of matter intermediate between liquid and solid. Gelatin is a common example of a partially ordered structure in a mesophase. Further, biological structures such as the lipid bilayers of cell membranes are examples of mesophases. Georges Friedel (1922) called attention to the "mesomorphic states of matter" in his scientific assessment of observations of the so-called liquid crystals. Conventionally a crystal is solid, and crystallization converts liquid to solid. The oxymoron of the liquid crystal is resolved through the notion of mesophases. The observations noted an optic axis persisting in materials that had been melted and had begun to flow. The term liquid crystal persists as a colloquialism, but use of the term was criticized in 1993: In The Physics of Liquid Crystals the mesophases are introduced from the beginning: ...certain organic materials do not show a single transition from solid to liquid, but rather a cascade of transitions involving new phases. The mechanical properties and the symmetry properties of these phases are intermediate between those of a liquid and those of a crystal. For this reason they have often been called liquid crystals. A more proper name is ‘mesomorphic phases’ (mesomorphic: intermediate form) Further, "The classification of mesophases (first clearly set out by G. Friedel in 1922) is essentially based on symmetry." Molecules that demonstrate mesophases are called mesogens. In technology, molecules in which the optic axis is subject to manipulation during a mesophase have become commercial products as they can be used to manufacture display devices, known as liquid-crystal displays (LCDs). The susceptibility of the optical axis, called a director, to an electric or magnetic field produces the potential for an optical switch that obscures light or lets it pass. Methods used include the Freedericksz transition and the twisted nematic field effect. From early liquid crystal displays the buying public has embraced the low-power optical switch facility of mesophases with director. Consider a solid consisting of a single molecular species and subjected to melting. Ultimately it is rendered to an isotropic state classically referred to as liquid. Mesophases occur before then when an intermediate state of order is still maintained as in the nematic, smectic, and columnar phases of liquid crystals. Mesophases thus exhibit anisotropy. LCD devices work as an optical switch which is turned off and on by an electric field applied to the mesogen with director. The response of the director to the field is expressed with viscosity parameters, as in the Ericksen-Leslie theory in continuum mechanics developed by Jerald Ericksen and Frank Matthews Leslie. Mesophase phenomena are important in many scientific fields. The publishing arms of professional societies have academic journals as needed. For instance, the American Chemical Society has both Macromolecules and Langmuir, while Royal Society of Chemistry has Soft Matter, and American Physical Society has Physical Review E, and Elsevier has Advances in Colloid and Interface Science.

In meteorology (and climatology), a mesonet, portmanteau of mesoscale network, is a network of (typically) automated weather and environmental monitoring stations designed to observe mesoscale meteorological phenomena. Dry lines, squall lines, and sea breezes are examples of phenomena that can be observed by mesonets. Due to the space and time scales associated with mesoscale phenomena, weather stations comprising a mesonet will be spaced closer together and report more frequently than synoptic scale observing networks, such as ASOS. The term mesonet refers to the collective group of these weather stations, and are typically owned and operated by a common entity. Mesonets usually record in situ surface weather observations but some involve other observation platforms, particularly vertical
