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 is 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 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 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 mice, which are their relatives, but seldom weigh over in the wild. The term ''rat'' is also used in the names of other small mammals th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Department Of Environment And Natural Resources
The Department of Environment and Natural Resources ( fil, Kagawaran ng Kapaligiran at Likas na Yaman, DENR or KKLY) is the executive department of the Philippine government responsible for governing and supervising the exploration, development, utilization, and conservation of the country's natural resources. History of the DENR The Department of Environment and Natural Resources was first established on January 1, 1917, as the Department of Agriculture and Natural Resources (DANR) through the enactment of Act No. 2666 by the Philippine Commission, otherwise known as "An Act to Re-organize the Executive Department of the Government of the Philippine Islands," on November 18, 1916. In 1932, the DANR was reorganized into the Department of Agriculture and Commerce (DAC). In 1947, a reorganization act changed the DAC back to the Department of Agriculture and Natural Resources. The Natural Resources arm of the DANR was finally spun off on May 17, 1974, as the Ministry of Natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrotum
The scrotum or scrotal sac is an anatomical male reproductive structure located at the base of the penis that consists of a suspended dual-chambered sac of skin and smooth muscle. It is present in most terrestrial male mammals. The scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens. It is a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and pampiniform plexus. The perineal raphe is a small, vertical, slightly raised ridge of scrotal skin under which is found the scrotal septum. It appears as a thin longitudinal line that runs front to back over the entire scrotum. In humans and some other mammals the scrotum becomes covered with pubic hair at puberty. The scrotum will usually tighten during penile erection and when exposed to cold temperatures. One testis is typically lower than the other to avoid compression in the event of an impact. The scrotum is biologicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. 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 anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

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 predator to prey. Information may be transferred to an "audience" of several receivers. Animal communication is a rapidly growing area of study in disciplines including animal behavior, sociology, neurology and animal cognition. Many aspects of animal behavior, such as symbolic name use, emotional expression, learning and 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 receiver should usually receive some benefit from the interact ...

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 neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the 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. Blackwell The study of substrate-borne vibrations used by animals is considered by some a distinct field called biotremology.
