Bulldog Bat
The bat family Noctilionidae, commonly known as bulldog bats or fishing bats, is represented by two extant species, the greater and the lesser bulldog bats, as well as at least one fossil species, '' Noctilio lacrimaelunaris'', from the Miocene of Argentina. The naked bulldog bat ('' Cheiromeles torquatus'') does not belong to this family, but to the family Molossidae, the free-tailed bats. They are found near water in the Neotropics, from Mexico to Argentina and also in the Caribbean islands. In these areas they can be found roosting in groups within hollow trees, caves, manmade homes, or other openings with enough space. While the two species exhibit different social and foraging behaviors both tend to return to a main roosting spot while also visiting other alternative roosting spots. Description The bulldog bats have orange to brown fur, and range in head-body length from 7 to 14 cm and weight of 20-75 g, which makes them quite large. They have relatively long legs, l ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greenwood Press (publisher)
Greenwood Publishing Group, Inc. (GPG) was an educational and academic publisher (middle school through university level) which was part of ABC-Clio. Since 2021, ABC-Clio and its suite of imprints, including GPG, are collectively imprints of British publishing house Bloomsbury Publishing. The Greenwood name stopped being used for new books in 2023. Established in 1967 as Greenwood Press, Inc., and based in Westport, Connecticut, GPG published reference works under its Greenwood Press imprint; and scholarly, professional, and general-interest books under its related imprint, Praeger Publishers (). Also part of GPG was Libraries Unlimited, which published professional works for librarians and teachers. Both of the latter became stand-alone imprints of ABC-Clio, in 2008–2009, after its purchase of GPG. History 1967–1999 The company was founded as Greenwood Press, Inc.

Ross Piper
Ross Piper is a British zoologist, entomologist, and explorer. Biography Piper's fascination by animals began at a young age through early encounters with a violet ground beetle and the caterpillar of an elephant hawk moth. This early interest led to a degree in zoology from Bangor University and a PhD in insect ecology from the University of Leeds. Piper has travelled widely in Europe, the Americas, Africa and Southeast Asia, searching for interesting and elusive beasts. Although his focus is arthropods, the sheer diversity of animal forms and lifestyles is a continual source of fascination. In 2015 he was awarded the Alumnus of the Year award by Bangor University and has since become a member of their alumni advisory board. He is also a student mentor for the University of Leeds and a Fellow of the Royal Geographical Society. He is currently a visiting research fellow at the University of Leeds and a visiting fellow at the University of Essex. His current projects include a ...

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 ...

Sacrum
The sacrum (: sacra or sacrums), in human anatomy, is a triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30. The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis. It forms joints with four other bones. The two projections at the sides of the sacrum are called the alae (wings), and articulate with the ilium at the L-shaped sacroiliac joints. The upper part of the sacrum connects with the last lumbar vertebra (L5), and its lower part with the coccyx (tailbone) via the sacral and coccygeal cornua. The sacrum has three different surfaces which are shaped to accommodate surrounding pelvic structures. Overall, it is concave (curved upon itself). The base of the sacrum, the broadest and uppermost part, is tilted forward as the sacral promontory internally. The central part is curved outward toward the posterior, allowing greater room for the pelvic cavity. In a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulldog
The Bulldog is a British breed of dog of mastiff type. It may also be known as the English Bulldog or British Bulldog. It is a stocky, muscular dog of medium size, with a large head, thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. Selective breeding for appearance has led to increased susceptibility to health problems including brachycephaly, hip dysplasia, heat sensitivity and skin infections. The dogs may not be bred in Norway or the Netherlands, because of concerns about their quality of life. The modern Bulldog was bred as a companion dog from the Old English Bulldog, a now-extinct breed used for bull-baiting until that was outlawed under the Cruelty to Animals Act of 1835. The Bulldog Club (in England) was formed in 1878, and the Bulldog Club of America was formed in 1890. While often used as a symbol of ferocity and courage, the modern Bulldog is generally a friendly, amiable dog. It is commonly kept as a pe ...
