Ursus Thibetanus
The Asian black bear (''Ursus thibetanus''), also known as the Asiatic black bear, moon bear and white-chested bear, is a medium-sized bear species native to Asia that is largely adapted to an arboreal lifestyle. It is distributed from southeastern Iran, Pakistan, India and the Himalayas to Mainland Southeast Asia, the Korean Peninsula, China and the Russian Far East to the islands of Honshū and Shikoku in Japan. It is listed as vulnerable on the IUCN Red List, and is threatened by deforestation and poaching for its body parts, which are used in traditional medicine. Taxonomy Ancestral and sister taxa Biologically and morphologically, Asian black bears represent the beginning of the arboreal specializations attained by sloth bears and sun bears. Asian black bears have karyotypes nearly identical to those of the five other ursine bears, and, as is typical in the genus, they have 74 chromosomes. From an evolutionary perspective, Asian black bears are the least changed of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrocław Zoo
The Wrocław Zoological Garden (), known simply as the Wrocław Zoo (), is a zoo on Wróblewski Street in Wrocław, Poland. It is the oldest zoo in Poland, having been first launched in 1865 as the Breslau Zoological Garden while the city was part of Prussia. During the World Wars it was first shut down, then reopened and finally destroyed. After World War II, it was rebuilt and ultimately opened in 1948 and now it is also the largest (in terms of the number of animals/species) zoo in the country. The zoo covers near downtown Wrocław. It is home to about 10,500 animals representing about 1,132 species. In terms of the number of animal species it is the third largest zoological garden in the world. The Wrocław Zoo is the most visited zoo in Poland and the fifth most visited zoo in Europe. The zoo is an accredited member of the European Association of Zoos and Aquaria (EAZA) and the World Association of Zoos and Aquariums (WAZA). History The beginnings of the zoo date back to ...

Poaching
Poaching is the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plants. In agricultural terms, the term 'poaching' is also applied to the loss of soils or grass by the damaging action of feet of livestock, which can affect availability of productive land, water pollution through increased runoff and welfare issues for cattle. Stealing livestock, as in cattle raiding, classifies as theft rather than poaching. The United Nations' Sustainable Development Goal 15 enshrines the sustainable use of all wildlife. It targets the taking of action on dealing with poaching and trafficking of protected species of flora and fauna to ensure their availability for present ...

Upper Merion Township, Montgomery County, Pennsylvania
Upper Merion Township is a township in Montgomery County, Pennsylvania, United States. The population was 33,613 at the 2020 U.S. Census. Located from Philadelphia, it consists of the villages of Gulph Mills, King of Prussia, Swedeland, Swedesburg, and portions of Radnor, and Wayne. The westernmost part of the township comprises the largest part of the Valley Forge National Historical Park. The township is the home of the King of Prussia mall, the third-largest shopping mall in the United States in terms of gross leasable area. King of Prussia also contains a major office park hosting firms such as Lockheed Martin and GlaxoSmithKline. The name Merion originates with the county of Merioneth in north Wales. ''Merioneth'' is an English-language translation of the Welsh ''Meirionnydd'', itself named after ''Meirchion'' (or ''Meirion''), grandson of ''Cunedda Wledig'' (b. ca. 380 A.D.), King of North Wales. History The township's incorporation dates to 1713 when the King o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Ursus Minimus
''Ursus minimus'' (the Auvergne bear) is an extinct species of bear, endemic to Europe during the Pliocene and Pleistocene, living from 5.3 to 1.8 Mya, existing for about . ''U. minimus'' appears to have given rise to '' Ursus etruscus''. The range of ''U. minimus'' was continental Europe, as far east as the Black Sea in Russia and as far south as Italy. The skeleton of ''U. minimus'' was very similar to that of the larger Asian black bear. With the exception of the age of the bones, it is often difficult to distinguish the remains of ''U. minimus'' from those of modern Asian black bears.''Search for the Golden Moon Bear: Science and Adventure in Pursuit of a New Species'' by Sy Montgomery published by Chelsea Green Publishing, 2009 Fossil distribution Sites and specimen ages: *Kossiakino 1, Stavropol'skaya, Russian Federation ~5.3—3.4 Mya. *Kuchurgan gravel site, Ukraine ~4.9—4.2 Mya. *Osztramos locality 7, Caves of Aggtelek Karst and Slovak Karst, Borsod-Abaúj-Zemplé ...

Villafranchian
Villafranchian age ( ) is a period of geologic time (3.5–1.0 Ma) spanning the Late Pliocene and Early Pleistocene used more specifically with European Land Mammal Ages. Named by Italian geologist Lorenzo Pareto for a sequence of terrestrial sediments studied near Villafranca d'Asti, a town near Turin, it succeeds the Ruscinian age, and is followed by the Galerian. The Villafranchian is sub-divided into six faunal units based on the localities of Triversa, Montopoli, Saint-Vallier, Olivola, Tasso and Farnetta.The Pleistocene Boundary and the Beginning of the Quaternary edited by John A. Van Couvering. Cambridge University Press 1997 A major division of European geological deposits and time, the Villafranchian is significant because it marked the first arrival of archai ...

Ursus Etruscus
''Ursus etruscus'', the Etruscan bear, is an extinct species of bear, endemic to Europe, Asia, and North Africa during the Early Pleistocene, living from approximately 2.2 million to around 1.4-1.2 million years ago. Taxonomy The Etruscan bear appears to have evolved from ''Ursus minimus'' and gave rise to the modern brown bear, '' Ursus arctos'', and the extinct cave bear, '' Ursus spelaeus''. The range of Etruscan bears was mostly limited to continental Europe, with specimens also recovered in the Great Steppe region of Eurasia. Fossil evidence for the Etruscan bear was recovered in Palestine, Greece, Croatia, and Tuscany, Italy. Some scientists have proposed that the early, small variety of ''U. etruscus'' of the middle Villafranchian era survives in the form of the modern Asian black bear. Morphology Not unlike the brown bears of Europe in size, it had a full complement of premolars, a trait carried from the genus '' Ursavus''. Ecology ''Ursus etruscus'', like modern ...

Old World
The "Old World" () is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia in the Eastern Hemisphere, previously thought of by the Europeans as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and ...

Chromosomes
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are visible under a light microscope only during the metaphase of cell division, where all chromosomes are aligned in the center of the cell in their condensed form. Before this stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the joined ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Ursus (genus)
''Ursus'' is a genus in the family Ursidae (bears) that includes the widely distributed brown bear, the polar bear, the American black bear, and the Asian black bear. The name is derived from the Latin ''ursus'', meaning ''bear''. Taxonomy and systematics Extant species A hybrid between grizzly bears and polar bears has also been recorded. Known commonly as a pizzly, prizzly, or grolar bear, the official name is simply " grizzly–polar bear hybrid".

Karyotype
A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as ...
