Galápagos Red Bat
The western red bat or desert red bat (''Lasiurus frantzii'') is a species of microbat in the family Vespertilionidae. It is found in western North America and Central America. Taxonomy Previously, it was believed to be a subspecies of the southern red bat (''Lasiurus blossevillii''), and was called ''Lasiurus blossevillii teliotis'' (abbreviated ''L. b. teliotis''). The western red bat is also very similar to the eastern red bat and is distinguished from each other by minor differences, such as the lack of white-tipped hair in the dorsal pelage in the western red bat and the presence of sparse fur in the lower third of their tail. Their habitats are separated by the Rocky Mountains and may overlap. Distribution and habitat The western red bat is found across western North America, ranging from southern Canada, through the western United States, down to Central America. The species has been recorded in Belize, Canada, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Society Of Mammalogists
The American Society of Mammalogists (ASM) was founded in 1919. Its primary purpose is to encourage the study of mammal A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three ...s, and professions studying them. There are over 4,500 members of this society, and they are primarily professional scientists who emphasize the importance of public policy and education. There are several ASM meetings held each year, and the society manages several publications such as the '' Journal of Mammalogy'', ''Special Publications'', '' Mammalian Species'', and ''Society Pamphlets''. The best known of these is the ''Journal of Mammalogy''. The ASM also maintains ''The Mammal Image Library'' which contains more than 1,300 mammal slides.

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the bioluminescence, ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of Active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bats Of Central America
Bats are flying mammals of the order Chiroptera (). 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 Yangochiroptera, with megabats as members of the f ...

Bats Of Canada
There are eighteen indigenous species of bats in Canada, which are found in many parts of the country. They are insectivores, and are prey to falcons, hawks, owls, snakes, cats, and raccoons.Health Canada Species The little brown bat is the most common and widely distributed of Canada's bat species.The nocturnal bat roosts in dark places during the day, and preys on insects at night. Their echolocation calls are emitted 20 times per second, increasing to 200 times per second while chasing prey. The habitat range of the big brown bat is in the southern parts of Quebec, Ontario, Manitoba, Saskatchewan, and British Columbia, and throughout Alberta. Males are solitary, whereas females "gather in maternity colonies in the spring and summer", consisting of up to 75 adults with their offspring. Smithsonian: Big Brown Bat They forage at night on dry, warm evenings, catching and eating flying insects in the air. They hibernate in the winter, migrating short distances to find an appropri ...

Animal Echolocation
Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the Echo (phenomenon) , 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 animal navigation , navigation, foraging, and predation, hunting prey. Echolocation calls can be Frequency modulation, frequency modulated (FM, varying in pitch during the call) or constant frequency (CF). FM offers precise range discrimination to localize the prey, at the cost of reduced operational range. CF allows both the prey's velocity and its movements to be detected by means of the Doppler effect. FM may be best for close, cluttered environments, while CF may be better in open environments or for hunting while perched. Echolocating animals include mammals, especially odontocetes (toothed whales) and some bat species, and, using s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insectivore
file:Common brown robberfly with prey.jpg, A Asilidae, robber fly eating a hoverfly An insectivore is a carnivore, carnivorous animal or plant which eats insects. An alternative term is entomophage, which can also refer to the Entomophagy in humans, human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects can stem from piscivory. At one time, insectivorous mammals were scientific classification, scientifically classified in an order (biology), order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each ...

Sociality
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of sociality is called a ''social animal'' ...

Microbat
Microbats constitute the suborder Microchiroptera within the order Chiroptera (bats). Bats have long been differentiated into Megachiroptera (megabats) and Microchiroptera, based on their size, the use of echolocation by the Microchiroptera and other features; molecular evidence suggests a somewhat different subdivision, as the microbats have been shown to be a paraphyletic group. Characteristics Microbats are long. Most microbats feed on insects, but some of the larger species hunt birds, lizards, frogs, smaller bats or even fish. Only three species of microbat feed on the blood of large mammals or birds ("vampire bats"); these bats live in South and Central America. Although most "Leaf-nose" microbats are fruit and nectar-eating, the name “leaf-nosed” isn't a designation meant to indicate the preferred diet among said variety. Three species follow the bloom of columnar cacti in northwest Mexico and the Southwest United States northward in the northern spring and then th ...

As American settlement in the U.S. Manifest destiny, expanded westward, the meaning of the term ''the West'' changed. Before around 1800, the crest of the Appalachian Mountains was seen as the American frontier, western frontier. The frontier moved westward and eventually the lands west of the Mississippi River were considered ''the West''. The U.S. Census Bureau's definition of the 13 westernmost states includes the Rocky Mountains and the Great Basin to the West Coast of the United States, Pacific Coast, and the mid-Pacific islands state, Hawaii. To the east of the Western United States is the Midwestern United States and the Southern United States, with Canada to the north and Mexico to the south.
