37-441: The Vespertilioninae are a subfamily of vesper bats from the family Vespertilionidae . Subfamily Vespertilioninae Vespertilionidae Vespertilionidae is a family of microbats, of the order Chiroptera , flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy
74-458: A 'little brown bat', although some species have fur that is brightly colored, with reds, oranges, and yellows all being known. The patterns of the superficial appearance include white patches or stripes that may distinguish some species. Most species roost in caves, although some make use of hollow trees , rocky crevices, animal burrows , or other forms of shelter. Colony sizes also vary greatly, with some roosting alone, and others in groups up to
111-424: A distinct four-season pattern, especially in the continental climate sector. Oceanic climates are created by the on-shore flow from the cool high latitude oceans to their west. This causes the climate to have mild summers and cool (but not cold) winters, and relative humidity and precipitation evenly distributed throughout the year. These climates are frequently cloudy and cool, and winters are milder than those in
148-789: A few highland areas of Tasmania , the Australian Alps and Southern Alps of New Zealand . This type of climate is even found in tropical areas such as the Papuan Highlands in Indonesia. Cfc is the categorization for this regime. Even in the middle of summer, temperatures exceeding 20°C (68 °F) are exceptional weather events in the most maritime of those locations impacted by this regime. In some parts of this climate, temperatures as high as 30°C (86°F) have been recorded on rare occasions, while temperatures as low as −15 °C (5 °F) have still been recorded on rare occasions. A cold variant of
185-421: A huge impact on the productivity of agriculture which is less common. Temperate regions have the majority of the world's population, which leads to large cities . There are a couple of factors why the climate of large city landscapes differs from the climate of rural areas. One factor is the strength of the absorption rate of buildings and asphalt, which is higher than that of natural land. The other large factor
222-434: A humid subtropical climate (most notably southeast China and North India ), there is an even sharper wet-dry season, called a monsoon subtropical climate or subtropical monsoon (Cwa). In these regions, winters are quite chilly and dry and summers have very heavy rainfall. Some Cwa areas in southern China report more than 80% of annual precipitation in the five warmest months (southwest monsoon). Mediterranean climates have
259-534: A landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C , when the mean temperature is above −3 °C (26.6 °F) but below 18 °C (64.4 °F) in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at 0 °C (32.0 °F). Continental climates are classified as D and considered to be varieties of temperate climates, having more extreme temperatures, with mean temperatures in
296-528: A million individuals. Species native to temperate latitudes typically hibernate to avoid cooler weather, while a few of the tropical species employ aestivation as a method of evading extremes of climate. Vespertilioninae Myotinae Kerivoulinae Murininae The four subfamilies of Vespertilionidae separate the presumably related taxa, tribes, and genera of extant and extinct taxa. The subfamilial treatments, based on morphological, geographical, and ecological comparisons have been recombined since

The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica . It owes its name to
370-461: A summer accent on rainfall. Regions with humid continental climates include southeastern Canada, the upper portions of the eastern United States , portions of eastern Europe , parts of China , Japan and the Korean Peninsula . These are temperate climates that compared to the subtropics are on the poleward edge of the temperate zone. Therefore, they still have four marked seasons including
407-435: A temperate region is found in southern Africa , where some 24,000 taxa (species and infraspecific taxa) have been described. Farming is a large-scale practice in the temperate regions (except for boreal/subarctic regions) due to the plentiful rainfall and warm summers, because most agricultural activity occurs in the spring and summer, cold winters have a small effect on agricultural production. Extreme winters or summers have

#1732858113941444-646: A warmer one, but are far more influenced by the polar zones than any other but the very polar climates ( tundra and ice cap climate ). Areas with subpolar oceanic climates feature an oceanic climate but are usually located closer to polar regions. As a result of their location, these regions tend to be on the cool end of oceanic climates. Snowfall tends to be more common here than in other oceanic climates. Subpolar oceanic climates are less prone to temperature extremes than subarctic climates or continental climates , featuring milder winters than these climates but still with similar summers. This variant of an oceanic climate
481-603: Is found in parts of coastal Iceland , the Faroe Islands , parts of Scotland , northwestern coastal areas of Norway such as Lofoten and reaching to 70° north on some islands, uplands near the coast of southwestern Norway, the Aleutian Islands of Alaska and northern parts of the Alaskan Panhandle , some parts of Southern Argentina and Chile (though most regions are still classified as continental subantarctic), and
518-486: Is known from the Holocene of Hawaii . All species are carnivorous and most are insectivores , exceptions are bats of genera Myotis and Pizonyx that catch fish and the larger Nyctalus species known to capture small passerine birds in flight. The dentition of the family varies between species; the dental formula of the family is: They rely mainly on echolocation to navigate and obtain food, but they lack
555-448: Is no longer included following its move to the separate family Cistugidae . Miniopterinae is additionally no longer recognized as a subfamily, as it was elevated to family status. A 2021 study attempted to resolve the systematic relationships among the pipistrelle-like bats of sub-Saharan Africa and Madagascar, with systematic inferences based on genetic and morphological analyses of more than 400 individuals across all named genera and
592-684: Is the classification published by the American Society of Mammalogists . Other authorities raise three subfamilies more: Antrozoinae (which is here the separate family of pallid bats ), Tomopeatinae (now regarded as a subfamily of the free-tailed bats ), and Nyctophilinae (here included in Vespertilioninae). Four subfamilies are recognized by Mammal Species of the World (2005), the highly diverse Vespertilioninae are also separated as tribes. Newer or resurrected genera are noted. The genus Cistugo
629-447: The Köppen climate classification . In contrast to oceanic climates, they are created by large land masses and seasonal changes in wind direction. This causes humid continental climates to have severe temperatures for the season compared to other temperate climates, meaning a hot summer and cold winter. Precipitation may be evenly distributed throughout the year, while in some locations there is
666-462: The tropics and the polar regions of Earth . These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates , where such variations are often small; they usually differ only in the amount of precipitation . In temperate climates, not only do latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large
703-510: The Cwb classification have significant monsoon influence, usually having dry winters and wet summers. These climates occur in the middle latitudes, between approximately 35° and 66.5° north and south of the equator. There is an equal climatic influence from both the polar and tropical zones in this climate region. Two types of climates are in this zone, a milder oceanic one and more severe seasonal continental one. Most prototypical temperate climates have
740-524: The closest relatives to the family are the free-tailed bats of family Molossidae . The monotypic genus Tomopeas , represented by the blunt-eared bat ( Tomopeas ravum ), is acknowledged as the potentially closest link between the Vespertilionidae and Molossidae, as it is the most basal member of the Molossidae and has intermediate characteristics of both families. The grouping of these subfamilies
777-595: The coldest month usually being below −3 °C (26.6 °F). The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic Circle (approximately 66.5° north latitude). The south temperate zone extends from the Tropic of Capricorn (approximately 23.5° south latitude) to the Antarctic Circle (at approximately 66.5° south latitude). In some climate classifications,

Others are specialised as long-winged genera, such as Lasiurus and Nyctalus , that use rapid pursuit to capture insects. The size range of the family is 3 to 13 cm (1.2 to 5.1 in) in head and body length; this excludes the tail, which is itself quite long in many species. They are generally brown or grey in colour, often an indiscriminate appearance as
851-410: The continental climate. Regions with oceanic climates include northwestern Europe , northwestern North America , southeastern and southwestern South America , southeastern Australia and most of New Zealand . Humid continental climates are considered as a variety of temperate climates due to lying in the temperate zones, although they are classified separately from other temperate climates in
888-522: The elaborate nose appendages of microbats that focus nasal emitted ultrasound . The ultrasound signal is usually produced orally, and many species have large external ears to capture and reflect sound, enabling them to discriminate and extract information. The vespertilionids employ a range of flight techniques. The wing surface is extended to the lower limbs, and the tails of this family are enclosed in an interfemoral membrane . Some are relatively slow-flying genera, such as Pipistrellus , that manipulate
925-636: The flying foxes and fruit bats of the megabat group Megachiroptera . The treatments of bat taxonomy have also included a placement amongst the Vespertilioniformes , or Yangochiroptera , as suborder Vespertilionoidea . Molecular data indicate the Vespertilionidae diverged from the Molossidae in the early Eocene period. The family is thought to have originated somewhere in Laurasia , possibly North America. A recently extinct species, Synemporion keana ,
962-483: The genus Vespertilio , which takes its name from a word for bat, vespertilio , derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds". (The term "evening bat" also often refers more specifically to one of the species, Nycticeius humeralis .) They are allied to the suborder Microchiroptera , the families of microbats separated from

1184-631: The opposite rainfall pattern. This climate is rare and is predominantly found in climate fringes and isolated areas of the Cascades and Andes Mountains , as the dry-summer climate extends further poleward in the Americas than elsewhere. The vast majority of the world's human population resides in temperate zones, especially in the Northern Hemisphere , due to its greater mass of land and lack of extreme temperatures. The biggest described number of taxa in
1221-505: The subtropical highland climate. Cold summer mediterranean climates ( Csc ) are present in high-elevation areas around coastal Csb climate areas, where the strong maritime influence prevents the average winter monthly temperature from dropping below 0 °C. Despite the maritime influence, they are classified alongside other mediterranean climates in the Köppen classification rather than oceanic climates like subtropical highland climates due to
1258-449: The temperate zone may be divided into several smaller climate zones, based on monthly temperatures, the coldest month, and rainfall. These can include the subtropical zone ( humid subtropical and Mediterranean climate ), and the cool temperate zone ( oceanic and continental climates ). These climates are typically found in the more equatorial regions of the temperate zone, between 23.5° and 35° north or south. They are influenced more by
