Crateromys Australis
The Dinagat bushy-tailed cloud rat, Dinagat crateromys or Dinagat cloud rat (''Crateromys australis'') is a species of cloud rat in the family Muridae. It is one of the eight cloud rats found only in the Philippines, and is specifically endemic to Dinagat Island. It is known locally as ''hawili''. A single specimen was discovered in 1975 by Dioscoro S. Rabor and his team during a scientific survey in Dinagat. The natural habitat is tropical lowland forests, which are facing environmental threats. Habitat loss is caused by progressive deforestation from heavy logging and chromite mining in the area. Almost 40 years after the original discovery, five live specimens were discovered by Milada Řeháková, Václav Řehák and William L.R. Oliver, in 2012. Discovery and rediscovery The Dinagat bushy-tailed cloud rat was first seen in 1975 in Balitbiton, Loreto Municipality, Surigao del Norte Province, Dinagat island during a scientific faunal survey. The only specimen (now the holotype) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Rat
The cloud rats or cloudrunners are a tribe (Phloeomyini) of arboreal and nocturnal herbivorous rodents endemic to the cloud forests of the Philippines. They belong to the family Muridae and include five genera: ''Batomys'' (hairy-tailed rats), ''Carpomys'' (dwarf cloud rats), '' Crateromys'' (bushy-tailed cloud rats), '' Musseromys'' (Luzon tree mice), and '' Phloeomys'' (giant cloud rats). They range in size from as large as to as small as . Cloud rats are threatened by habitat loss and illegal hunting. Several species are endangered or critically endangered. Description Cloud rats are characterized by long furry or hairy tails and short hind limbs with grasping feet. They spend most of their time in the canopy of cloud forests, hence the name "cloud rat" or "cloudrunner". They are believed to be entirely herbivorous, primarily eating leaves, buds, bark, fruits, and seeds. Their ecology and behavior are poorly known.

Endemic Fauna Of The Philippines
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becom ...

Rats Of Asia
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include ''Neotoma'' (pack rats), ''Bandicota'' (bandicoot rats) and ''Dipodomys'' (kangaroo rats). Rats are typically distinguished from mouse, mice by their size. Usually the common name of a large muroid rodent will include the word "rat", while a smaller muroid's name will include "mouse". The common terms ''rat'' and ''mouse'' are not Taxonomy (biology), taxonomically specific. There are 56 known species of rats in the world. Species and description The best-known rat species are the black rat (''Rattus rattus'') and the brown rat (''Rattus norvegicus''). This group, generally known as the Old World rats or true rats, originated in Asia. Rats are bigger than most Old World mouse, mice, which are their relatives, but seldom weigh over in the wild. The term ''rat'' is also used in the names ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scrotum
In most terrestrial mammals, the scrotum (: scrotums or scrota; possibly from Latin ''scortum'', meaning "hide" or "skin") or scrotal sac is a part of the external male genitalia located at the base of the penis. It consists of a sac of skin containing the external spermatic fascia, testicles, epididymides, and vasa deferentia. The scrotum will usually tighten when exposed to cold temperatures. The scrotum is homologous to the labia majora in females. Structure In regards to humans, the scrotum is a suspended two-chambered sac of skin and muscular tissue containing the testicles and the lower part of the spermatic cords. It is located behind the penis and above the perineum. The perineal raphe is a small, vertical ridge of skin that expands from the anus and runs through the middle of the scrotum front to back. The scrotum is also a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and ...

Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Animal Communication
Animal communication is the transfer of information from one or a group of animals (sender or senders) to one or more other animals (receiver or receivers) that affects the current or future behavior of the receivers. Information may be sent intentionally, as in a courtship display, or unintentionally, as in the transfer of scent from the predator to prey with kairomones. Information may be transferred to an "audience" of several receivers. Animal communication is a rapidly growing area of study in disciplines including Ethology, animal behavior, sociology, neurology, and animal cognition. Many aspects of animal behavior, such as symbolic name use, emotional expression, learning, and Animal sexual behavior, sexual behavior, are being understood in new ways. When the information from the sender changes the behavior of a receiver, the information is referred to as a "signal". Signalling theory predicts that for a signal to be maintained in the population, both the sender and receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioacoustics
Bioacoustics is a cross-disciplinary science that combines biology and acoustics. Usually it refers to the investigation of sound production, dispersion and reception in animals (including humans). This involves neurophysiology, neurophysiological and anatomy, anatomical basis of sound production and detection, and relation of acoustic Signal (electrical engineering), signals to the Transmission medium, medium they disperse through. The findings provide clues about the evolution of acoustic mechanisms, and from that, the evolution of animals that employ them. In underwater acoustics and fisheries acoustics the term is also used to mean the effect of plants and animals on sound propagated underwater, usually in reference to the use of sonar technology for biomass estimation.Simmonds J. & MacLennan D. (2005). ''Fisheries Acoustics: Theory and Practice'', second edition. Wiley-Blackwell, Blackwell The study of substrate-borne vibrations used by animals is considered by some a distinct ...
