Crematogaster Aurora
''Crematogaster aurora'' is a valid species of myrmicine ant that lived in Baltic Europe about 46 million to 43 million years ago during the Cenozoic era Eocene epoch. ''C. aurora'' has a similar look to the ant genus '' Acanthomyrmex'' and shares some similarities with the ant genus ''Pristomyrmex''. The fossil found of ''C. aurora'' is of a queen ant that is brown in coloration. It probably died by drowning in a lake approximately 46 million years ago. References Insects described in 2015 aurora An aurora ( aurorae or auroras), also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in Earth's sky, predominantly observed in high-latitude regions (around the Arc ...

Queen Ant
A queen ant (also known as a gyne) is an adult, reproducing female ant in an ant colony; she is usually the mother of all the other ants in that colony. Some female ants, such as the '' Cataglyphis'', do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning, and all of those offspring will be female. Others, like those in the genus ''Crematogaster'', mate in a nuptial flight. Queen offspring ants among most species develop from larvae specially fed in order to become sexually mature. Depending on the species, there can be either a single mother queen, or potentially hundreds of fertile queens. Not every colony of ants has a queen. Some colonies have multiple queens. Queen ants are the only members of a colony to lay eggs. After mating, they can produce thousands, sometimes millions, of eggs during their lifetime. A queen of '' Lasius niger'' was held in captivity by German entomologist Hermann Appel for 28 years; also a ''Pogonomyrmex ow ...

Color
Color (or colour in English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-our, -or, see spelling differences) is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, emission spectra, emission, Reflection (physics), reflection and Transmittance, transmission. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelengths, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain. Colors have perceived properties such as hue, colorfulness (saturation), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Amber
Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014 and 400 tonnes in 2015. Baltic amber is also found in Poland, as well as the Baltic states. Bitterfeld amber from the brown coal mines near Bitterfeld in Germany was previously thought to be redeposited Baltic amber, but is now known to be chemically distinct, though like with Ukrainian Rovno amber, it is thought to have been deposited around the same time as Baltic amber. Because Baltic amber contains from 3 to 8% succinic acid, it is also termed succinite. Geologic context ''In situ'' Balt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene Insects Of Europe
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in com ...

Crematogaster
''Crematogaster'' is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (insect anatomy), gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal (tree-dwelling). These ants are also known as acrobat ants. Cocktail ants acquire food largely through predation on other insects, such as wasps.Schatz, Bertrand, and Martine Hossaert-Mckey. "Interactions of the Ant Crematogaster Scutellaris with the Fig/fig Wasp Mutualism." Ecological Entomology 28.3 (2003): 359-68. Print. They use venom to stun their prey and a complex trail-laying process to lead comrades to food sources. Like most ants, ''Crematogaster'' species reproduce by partaking in nuptial flights, where the queen acquires the sperm used to fertilize every egg throughout her life. Predatory ...

Insects Described In 2015
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues.

Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of ocean ...

Drowning
Drowning is a type of Asphyxia, suffocation induced by the submersion of the mouth and nose in a liquid. Submersion injury refers to both drowning and near-miss incidents. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to Hypothermia, low body temperature, Pulmonary aspiration, aspiration, or acute respiratory distress syndrome (respiratory failure from lung inflammation). Drowning is more likely to happen when spending extended periods of time near large bodies of water. Risk factors for drowning include alcohol use, drug use, epilepsy, minimal swim training or a complete l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pristomyrmex
''Pristomyrmex'' is a genus of ants in the subfamily Myrmicinae. Distribution and habitat The genus is composed of 59 extant species restricted to the Old World tropics and a single extinct species, ''Pristomyrmex rasnitsyni'', described from Scandinavian amber. Its center of diversity is the Oriental region, though species are also known from the Australian rainforests, Africa, Mauritius and Réunion. Most of the species inhabit the rainforest, forage as predators or scavengers, and tend to nest in soil, leaf litter or rotten wood.

Valid Name (zoology)
In zoological nomenclature, the valid name of a taxon is the correct scientific name for that taxon. The valid name must be used for that taxon, regardless of any other name that may currently be used for that taxon, or may previously have been used. A name can only be valid (or invalid) when it is an available name under the International Code of Zoological Nomenclature (ICZN); if a name is unavailable, then it cannot be considered either valid or invalid. In contrast, a name which is available but not the correct name for a taxon is known as an invalid name. There are two categories of invalid names. Subjectively invalid names Subjectively invalid names are names that have been rendered invalid by individual scientific judgement or opinion. Taxonomists may differ in their opinion, and names considered invalid by one researcher may be considered valid by another. They include: :* Junior subjective synonyms – synonyms described from different types, which were previousl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
