Hokkaidō
is Japan, Japan's Japanese archipelago, second largest island and comprises the largest and northernmost Prefectures of Japan, prefecture, making up its own List of regions of Japan, region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only Cities designated by government ordinance of Japan, ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are Kuril Islands dispute, claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''.Louis Frédéric, Nussbaum, Louis-Frédéric. (2005).

Eptesicus Nilssonii Hibernating
''Eptesicus'' is a genus of bats, commonly called house bats or serotine bats, in the family Vespertilionidae. The genus name is likely derived from the Greek words ''ptetikos'' 'able to fly' or ''petomai'' 'house flier', although this is not certain. Species 28 species have been identified within the genus. Of these, 19 are from South America. These species are grouped into two subgenera In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between ...: ''Eptesicus'' and ''Histiotus''.

Arctic Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise for 40 successive days in midwinter. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Echolocation
Echolocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments. Echolocating animals include some mammals (most notably Laurasiatheria) and a few birds, especially some bat species and odontocetes (toothed whales and dolphins), but also in simpler forms in other groups such as shrews, and two cave-dwelling bird groups, the so-called cave swiftlets in the genus ''Aerodramus'' (formerly ''Collocalia'') and the unrelated oilbird ''Steatornis caripensis''. Early research The term ''echolocation'' was coined in 1938 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. As Griffin described in his book, the 18th centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghost Moth
The ghost moth or ghost swift (''Hepialus humuli'') is a moth of the family Hepialidae. It is common throughout Europe, except for in the far south-east. Female ghost moths are larger than males, and exhibit sexual dimorphism with their differences in size and wing color. The adults fly from June to August and are attracted to light. The species overwinters as a larva. The larva is whitish and maggot-like and feeds underground on the roots of a variety of wild and cultivated plants (see list below). The species can be an economically significant pest in forest nurseries. The term ghost moth is sometimes used as a general term for all hepialids. The ghost moth gets its name from the hovering display flight of the male, sometimes slowly rising and falling, over open ground to attract females. In a suitable location several males may display together in a lek. Physiology and description Female ghost moths have a wingspan of 50–70 mm. They have yellowish-buff forewing ...

Serotine Bat
The serotine bat (''Eptesicus serotinus''), also known as the common serotine bat, big brown bat, or silky bat, is a fairly large Eurasian bat with quite large ears. It has a wingspan of around and often hunts in woodland. It sometimes roosts in buildings, hanging upside down, in small groups or individually. The name serotine is derived from the Latin ''serotinus'', which means 'evening', while the generic name derives from Greek ἔπιεν and οίκος, which means 'house flyer'. Taxonomy The following subspecies have been recognised. *''Eptesicus serotinus boscai'': southern Iberia and Morocco *''Eptesicus serotinus pashtonus'': Pakistan and Afghanistan *''Eptesicus serotinus serotinus'': northern and eastern Europe and western Asia *''Eptesicus serotinus turcomanus'': central Asia and Xinjiang The Oriental serotine (''E. pachyomus'') and its constituent subspecies were formerly considered a subspecies of ''E. serotinus'', comprising its eastern populations, and is s ...

Mammals Of Korea
Approximately 100 species of mammal are known to inhabit, or to have recently inhabited, the Korean Peninsula and its surrounding waters. This includes a few species that were introduced in the 20th century; the coypu was introduced for farming in the 1990s, and the muskrat was introduced in the early 20th century into the Russian Far East, and was subsequently first recorded in Korea in the Tumen River basin in 1965. The Siberian tiger is the national animal of South Korea. The Siberian tiger and Amur leopard have most likely been extirpated from Korea, but are still included in standard lists of Korean mammals. Most Korean mammal species are found only in a small part of Korea. The large southeastern island of Jeju, and the rugged northeastern Paektu Mountain region, are particularly known for their distinctive mammal species. Several species, including the Dsinezumi shrew, are found only on Jeju, while many other species, such as the wild boar, are absent or extirpat ...

Bats Of Asia
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochirop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
