Callipogon Relictus
''Callipogon relictus'' is a species of longhorn beetle which is mostly found in Korea, but also in China and southern part of Russian Far East. It inhabits mixed and deciduous forests. The population of ''Callipogon relictus'' is decreasing due to deforestation and uncontrolled collection, and therefore the species are listed in the Russian Red Book (category II). The larvae of ''Callipogon relictus'' develop in the drying deciduous trees. The process takes 4 to 6 years, and the same tree can be populated by larvae several times a year. Larvae bring along spores of the fungus ''Pleurotus citrinopileatus'', that contributes to degradation of the tree. With the length reaching up to , ''Callipogon relictus'' is the largest beetle of Russia. Larvae of different longhorn beetles can coexist in the same tree, such as ''Callipogon relictus'', ''Rosalia coelestis'', '' Leptura thoracica'', '' Rhabdoclytus acutivittis'', '' Anoplodera cyanea'' and several other species.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Raychikhinsk
Raychikhinsk (russian: Райчи́хинск) is a town in Amur Oblast, Russia, located in the Zeya– Bureya basin, about from the Amur River and the border with China, and about east of Blagoveshchensk, the administrative center of the oblast. Population: History The town is located near a brown coal deposit which had been known of since the late 1800s. Mining began in 1913, with the foundation of the first permanent settlement in 1932, named Raychikha () after a local stream. From 1938 until 1942, Raychikha was host to a prison camp of the gulag system, where up to 11,000 prisoners were kept for forced labor in the mining of coal. In 1944, it was granted town status and given its present name. Administrative and municipal status Within the framework of administrative divisions, it is, together with three rural localities, incorporated as Raychikhinsk Urban Okrug—an administrative unit with the status equal to that of the districts.Law #127-OZ As a municipal d ...

Amur Oblast
Amur Oblast ( rus, Аму́рская о́бласть, r=Amurskaya oblast, p=ɐˈmurskəjə ˈobləsʲtʲ) is a federal subject of Russia (an oblast), located on the banks of the Amur and Zeya Rivers in the Russian Far East. The administrative center of the oblast, the city of Blagoveshchensk, is one of the oldest settlements in the Russian Far East, founded in 1856. It is a traditional center of trade and gold mining. The territory is accessed by two railways: the Trans-Siberian Railway and the Baikal–Amur Mainline. As of the 2010 Census, the oblast's population was 830,103. Amur Krai () or Priamurye () were unofficial names for the Russian territories by the Amur River used in the late Russian Empire that approximately correspond to modern Amur Oblast. Geography Amur Oblast is located in the southeast of Russia, between Stanovoy Range in the north and the Amur River in the south, and borders with the Sakha Republic in the north, Khabarovsk Krai and the Jewish Auto ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prothorax
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Maxilla (arthropod Mouthpart)
In arthropods, the maxillae (singular maxilla) are paired structures present on the head as mouthparts in members of the clade Mandibulata, used for tasting and manipulating food. Embryologically, the maxillae are derived from the 4th and 5th segment of the head and the maxillary palps; segmented appendages extending from the base of the maxilla represent the former leg of those respective segments. In most cases, two pairs of maxillae are present and in different arthropod groups the two pairs of maxillae have been variously modified. In crustaceans, the first pair are called maxillulae (singular maxillula). Modified coxae at the base of the pedipalps in spiders are also called "maxillae", although they are not homologous with mandibulate maxillae. Myriapoda Millipedes In millipedes, the second maxillae have been lost, reducing the mouthparts to only the first maxillae which have fused together to form a gnathochilarium, acting as a lower lip to the buccal cavity and the man ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Andrey Semyonov-Tyan-Shansky
Andrey Petrovich Semyonov-Tyan-Shansky (russian: Андре́й Петро́вич Семёнов-Тянь-Ша́нский) (9 June 1866–1942) was a Russian entomologist specializing in beetles. He was the son of Pyotr Semyonov-Tyan-Shansky. He entered the St. Petersburg University in 1885. In 1888 and 1889 he traveled to the Trans-Caspian and Turkestan regions in search of insects, then in 1890 became a curator at the Imperial Academy of Sciences. He worked at the museum only until 1896 and then worked at his home. He studied mainly the Hymenoptera and Dermaptera. Citations of this author most frequently bear the spelling Semenov-Tian-Shanskij (e.g. He also took an interest in the poetry of Pushkin, the protection of nature, and a range of other subjects.

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of intera ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
