Siberian Spruce
''Picea obovata'', the Siberian spruce, is a spruce native to Siberia, from the Ural Mountains east to Magadan Oblast, and from the Arctic tree line south to the Altay Mountains in northwestern Mongolia. It is a medium-sized evergreen tree growing to 15–35 m tall, and with a trunk diameter of up to 1.5 m, and a conical crown with drooping branchlets. The shoots are orange-brown, with variably scattered to dense pubescence. The leaves are needle-like, 1–2 cm long, rhombic in cross-section, shiny green to grayish-green with inconspicuous stomatal lines; the leaves subtending a bud are distinctively angled out at a greater angle than the rest of the leaves (a character shared by only two or three other spruces). The cones are cylindric-conic, 5–10 cm long and 1.5–2 cm broad, green or purple, maturing glossy brown 4–6 months after pollination, and have stiff, smoothly rounded scales. The specific name ''obovata'' means "egg-shaped." It is an important timber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khanty–Mansi Autonomous Okrug
Khanty-Mansi Autonomous Okrug–Yugra, also known as Khanty-Mansia (Khantia-Mansia), is a federal subject of Russia (an autonomous okrug of Tyumen Oblast). It has a population of 1,532,243 as of the 2010 Census. Its administrative center is located at Khanty-Mansiysk. The peoples native to the region are the Khanty and the Mansi, known collectively as Ob-Ugric peoples, but today the two groups only constitute 2.5% of the region's population. The local languages, Khanty and Mansi, are part of the Ugric branch of the Finno-Ugric language family, and enjoy a special status in the autonomous okrug. Russian remains the only official language. In 2012, the majority (51%) of the oil produced in Russia came from Khanty-Mansi Autonomous Okrug, giving the region great economic importance in Russia and the world. It borders Yamalo-Nenets Autonomous Okrug to the north, Komi Republic to the northwest, Sverdlovsk Oblast to the west, Tyumen Oblast to the south, Tomsk Oblast to th ...

Conifer Cone
A conifer cone, or in formal botanical usage a strobilus, : strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like. The cone of Pinophyta (conifer clade) contains the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually ephemeral and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the geometric cone. The individual plates of a cone are known as ''scales''. In conifers where the cone develops over more than one year (such as pines), the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale, is called an ''umbo'', while the second year's growth is called th ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Heredity (journal)
''Heredity'' is a monthly peer-reviewed scientific journal published by Nature Portfolio. It covers heredity in a biological sense, i.e. genetics. The journal was founded by Ronald Fisher and C. D. Darlington in 1947 and is the official journal of The Genetics Society. From 1996 the publishing was taken over by Nature Portfolio. The editor-in-chief is Sara Goodacre. According to the ''Journal Citation Reports'', the journal has a 2021 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a type of journal ranking. Journals with higher impact factor values are considered more prestigious or important within their field.

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinians, Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Phenotypic trait, Trait inheritance and Molecular genetics, molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the Cell (bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velodromes
A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve. History The first velodromes were constructed during the late 1870s, the oldest of which is the Preston Park Velodrome, Brighton, United Kingdom, built in 1877 by the British Army. Some were purpose-built just for cycling, and others were built as part of facilities for other sports; many were built around athletics tracks or other grounds and any banking was shallow. Reflecting the then-lack of international standards, sizes varied and not all were built as ovals: for example, Preston Park is long and features four straights linked by banked curves, while the Portsmouth velodrome, in Portsmouth, has a single straight linked by one long curve. The oldest surviving regular velodrome two-straight oval tracks is from 1889, located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cydia Illutana
__NOTOC__ ''Cydia illutana'' is a small moth of the family Tortricidae. It is found from western and central Europe (Great Britain, the Netherlands, Austria, Germany and France), north to Scandinavia (Denmark, Norway, Sweden and Finland) and east to Russia (Siberia). The wingspan is 12–14 mm. Adults are on wing in May and June. There is one generation per year. The caterpillars feed on the scales of conifer cones. Host plants are European silver fir (''Abies alba''), European larch (''Larix decidua''), Dahurian larch (''L. gmelinii''), Siberian larch (''L. sibirica''), Norway spruce (''Picea abies''), Siberian spruce (''P. (a.) obovata'') and common Douglas-fir (''Pseudotsuga menziesii''). They pupate in peat or rotting wood.

Tortrix Moth
The Tortricidae are a family of moths, commonly known as tortrix moths or leafroller moths, in the order Lepidoptera. This large family has over 11,000 species described, and is the sole member of the superfamily Tortricoidea, although the genus '' Heliocosma'' is sometimes placed within this superfamily. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting posture is with the wings folded back, producing a rather rounded profile. Notable tortricids include the codling moth and the spruce budworm, which are among the most well-studied of all insects because of their economic impact. Description Tortricid moths are generally small, with a wingspan of 3 cm or less.Hanson, Paul E. (2018). ''Insects and Other Arthropods of Tropical America''. Cornell University Press. Many species are drab and have mottled and marbled brown colors, but some diurnal species are brightly colored and mimic other moths of the families Geometrid ...

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spruce Beer
Spruce beer is a beverage flavored with the buds, needles, or essence of spruce trees. ''Spruce beer'' can refer to either alcoholic or non-alcoholic beverages. A number of flavors are associated with spruce-flavored beverages, ranging from floral, citrus, and fruity, to cola-like flavors to resinous and piney. This diversity in flavor likely comes from the choice of spruce species, the season in which the spruce ingredients are harvested, and the manner of preparation. Using evergreen needles to create beverages was practiced in both Northern Europe and North America. Certain Indigenous peoples of North America used the drink as a cure for scurvy during the winter months when fresh fruits were not available, as the fresh shoots of many spruces and pines are a natural source of vitamin C. It may also have been brewed in Scandinavia prior to European contact with the Americas, but most French and British explorers were ignorant of its use as a treatment for scurvy when they arriv ...
