The brown bear is a large bear native to Eurasia and North America. It is one of the largest land carnivorans, rivaled in size only by its closest relative, the polar bear, which is much less variable in size and slightly bigger on average. The brown bear is a sexually dimorphic species, as adult males are larger and more compactly built than females. The pelage ranges from reddish to yellowish-brown, and dark brown to cream in color. The only extant bear with a hump formed entirely of muscle on its shoulders, the brown bear uses these muscles, as well its large paws to effectively dig through dirt. Its teeth are similar to those of other bears and reflect its dietary plasticity.
Arabidopsis (rockcress) is a genus in the family Brassicaceae. They are small flowering plants related to cabbage and mustard. This genus is of great interest since it contains thale cress, one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced. Changes in thale cress are easily observed, making it a very useful model.
The sun bear is a species in the family Ursidae occurring in the tropical forests of Southeast Asia. It is the smallest bear species, standing nearly 70 cm (28 in) at the shoulder and weighing 25–65 kg (55–143 lb). It is stockily built, with large paws, strongly curved claws, small, rounded ears and a short snout. The fur is generally short and jet black, but can vary from grey to red. The sun bear gets its name from its characteristic orange to cream-coloured chest patch. Its unique morphology—inward-turned front feet, flattened chest, powerful forelimbs with large claws—suggests adaptations for climbing.
The Asian black bear, also known as the Indian black bear, 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 lives in the Himalayas, southeastern Iran, the northern parts of the Indian subcontinent, Mainland Southeast Asia, the Korean Peninsula, China, the Russian Far East, the islands of Honshū and Shikoku in Japan, and Taiwan. 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.
Marginocephalia is a clade of ornithischian dinosaurs that is characterized by a bony shelf or margin at the back of the skull. These fringes were likely used for display. There are two clades included in Marginocephalia: the thick-skulled Pachycephalosauria and the horned Ceratopsia. All members of Marginocephalia were primarily herbivores. They basally used gastroliths to aid in digestion of tough plant matter until they convergently evolved tooth batteries in Neoceratopsia and Pachycephalosauria. Marginocephalia first evolved in the Jurassic Period and became more common in the Cretaceous. They are basally small facultative quadrupeds while derived members of the group are large obligate quadrupeds. Primitive marginocephalians are found in Asia, but the group migrated upwards into North America.
The Himalayan black bear is a subspecies of the Asian black bear. It is distinguished from U. t. thibetanus by its longer, thicker fur and smaller, whiter chest mark. The species is considered an ecological indicator and a keystone species of the environment. The species plays a vital role as a primary seed disperser in maintaining the stability of the ecosystem. On average, they measure from 56 to 65 inches nose to tail and weigh from 200 to 265 pounds, though they may weigh as much as 400 pounds in the fall, when they are fattening up for hibernation.
The Cernavodă culture, ca. 4000–3200, is a late Copper Age archaeological culture distributed along the lower Eastern Bug River and Danube and along the coast of the Black Sea and somewhat inland, generally in present-day Bulgaria and Romania. It is named after the Romanian town of Cernavodă.
An ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae). Species and subspecies of bear known to have produced offspring with another bear species or subspecies include American black bears, grizzly bears, and polar bears, all of which are members of the genus Ursus. Bears not included in Ursus, such as the giant panda, are expected to be unable to produce hybrids with other bears. The giant panda bear belongs to the genus Ailuropoda.
Tungusic peoples are an ethnolinguistic group formed by the speakers of Tungusic languages. They are native to Siberia, China, and Mongolia.
The Gobi bear, known in Mongolian as the Mazaalai (Мазаалай), is a subspecies of the brown bear that is found in the Gobi Desert of Mongolia. It is listed as critically endangered by the Mongolian Redbook of Endangered Species and by IUCN standards. Currently, there are only 31 bears left in the Mongolian Gobi Desert; through long-term genetic monitoring it is known that the population is relatively stable, however, the sex ratio is highly skewed towards males. Gobi bears are separated by enough distance from other brown bear populations to achieve reproductive isolation. In 1959, hunting of the animal was prohibited in order to preserve the dying subspecies.
Güldenstädt's shrew is a species of mammal in the family Soricidae. It is sometimes considered a subspecies of the lesser white-toothed shrew, but more recent studies support it being a distinct species. It is named after Johann Anton Güldenstädt.
The Ussuri brown bear, also known as the Ezo brown bear, Russian grizzly bear, or the black grizzly bear, is a subspecies of the brown bear or a population of the Eurasian brown bear. One of the largest brown bears, a very large Ussuri brown bear may approach the Kodiak bear in size. It is not to be confused with the North American grizzly bear.
Paralligator is an extinct genus of neosuchian crocodylomorph that lived during the Late Cretaceous (Cenomanian-Maastrichtian) period in what is now the Bayan Shireh and Nemegt formations of Mongolia, approximately 96 million to 70 million years ago. P. gradilifrons reached up to 4 m (13 ft) in length.
Xylocopa valga is a species of carpenter bee common to: western, central and southern Europe, except for far northern latitudes; the Caucasus; Middle East; Central Asia; and Mongolia. The species has become extinct in Latvia and Lithuania.
Arabidopsis arenosa, the sand rock-cress, is a species of flowering plant in the family Brassicaceae. It is found mostly in Central Europe in both a diploid and an autotetraploid form. This sets it apart from the other, mostly diploid, Arabidopsis species including the closely related Arabidopsis lyrata or Arabidopsis thaliana, the model plant species.
Kate Robb is an Australian marine mammalogist who, along with colleagues, declared in 2011 a new species of the genus Tursiops, and formally named it the Burrunan dolphin, Tursiops australis. She is the Founding Director and Head of Research at the Marine Mammal Foundation in Melbourne in the Australian state of Victoria.
Podiates are a proposed clade containing the Amorphea and the organisms now assigned to the clade CRuMs. Ancyromonadida does not appear to have emerged in this grouping. Sarcomastigota is a proposed subkingdom that includes all the podiates that are not animals or fungi. Sulcozoa is a proposed phylum within Sarcomastigota that does not include the phyla Amoebozoa (clade) and Choanozoa (paraphyletic), i.e. it includes the proposed subphyla Apusozoa and Varisulca
Epiperipatus isthmicola is a species of velvet worm in the Peripatidae family. This species is a dark brown, almost black, without any pattern on its dorsal surface. Females of this species have 29 to 32 pairs of legs; males have 26 or 27. Females range from 20 mm to 73 mm in length, whereas males range from 20 mm to 48 mm. The type locality is in Costa Rica.
Protarctos is an extinct genus of basal ursine bear that lived in North America and Eurasia during the Pliocene and into Early Pleistocene.
Scolopendra pinguis is a species of centipede in the subfamily Scolopendrinae that is endemic to Southeast Asia.
