Northern Luzon Giant Cloud Rat
The northern Luzon giant cloud rat (''Phloeomys pallidus'') or northern Luzon slender-tailed cloud rat, also known as ''bu-ot'' in Filipino, is a large species of rodent in the family Muridae. It is only found in Luzon, the Philippines. Appearance This very large rodent weighs and is long, including its tail. The colour of its relatively long pelage, which also covers the tail, is highly variable, but it is usually pale brown-grey or white with some dark brown or black patches. They often have a black mask and collar but can also be entirely white. The only other member of the genus ''Phloeomys'', the southern Luzon giant cloud rat (''P. cumingi''), has a more southerly distribution, is generally smaller (although with some overlap), and is entirely dark brown. However, the occasional brown Northern Luzon giant cloud rat has been reported in the Mountain Province, and the taxonomic limits between the two ''Phloeomys'' are not fully resolved.

Alfred Nehring
Alfred Nehring (29 January 1845 in Bad Gandersheim, Gandersheim – 29 September 1904 in Charlottenburg, Berlin-Charlottenburg) was a German zoologist and paleontologist. He was a founding professor of zoology at the Royal agricultural university in Berlin. Nehring was born in Gandersheim and was educated at Helmstedt and then in Braunschweig, passing his exams in 1863. He then joined the University of Göttingen and then received a doctorate from Halle in 1867. He passed the teachers exam and joined the Royal Gymnasium in Wesel (1867) , later moving to Wolfenbüttel (1871). His paleontology work attracted interest from Rudolf Virchow, and in 1881 he became a professor of zoology at the newly founded Royal Agricultural University / ''Landwirtschaftliche Hochschule'' in Berlin. He worked there until his death. His main interests were in the Pleistocene fossils from Thiede, Immendorf, Groß- and Klein-Vahlberg, Schöppenstedt, Hornburg and Osterode, Neinstedt, Suderode, Gernrode, Que ...

Nocturnality
Nocturnality is a behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including humans (except for ni ...

Rodents Of The Philippines
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Once included with rodents, rabbits, hares, and pikas, wh ...

Fauna Of Luzon
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a book ...

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] |
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. Cloud rats belonging to the genera ''Batomys'', ''Crateromys' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Extinction
Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with extinction, global extinctions. Local extinctions mark a change in the ecology of an area. It has sometimes been followed by a replacement of the species taken from other locations, such as with wolf reintroduction. Discussion Glacial period, Glaciation is one factor that leads to local extinction. This was the case during the Quaternary glaciation, Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extinct from islands over time; this can be either local extinction if the species also occurs elsewhere, or in cases of endemism, island endemism, outright ex ...

Sierra Madre (Philippines)
The Sierra Madre is the longest mountain range in the Philippines. Spanning over , it runs from the province of Cagayan down to the province of Quezon in a north-south direction on the eastern portion of Luzon, the largest island of the archipelago. It is bordered by the Pacific Ocean to the east, Cagayan Valley to the northwest, Central Luzon to the midwest, and Calabarzon to the southwest. Some communities east of the mountain range, along the coast, are less developed and so remote that they can only be accessed by taking a plane or a boat. The country's largest protected area, the Northern Sierra Madre Natural Park, is situated at the northern part of the range in the province of Isabela. The park is in the UNESCO tentative list for World Heritage List inscription. Environmentalists, scholars, and scientists have been urging the government to include the other parks within the Sierra Madre mountains for a UNESCO site that would include the whole mountain range from Cagay ...

Pest (organism)
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats and cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rice
Rice is a cereal grain and in its Domestication, domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species ''Oryza sativa'' (Asian rice)—or, much less commonly, ''Oryza glaberrima'' (African rice). Asian rice was domesticated in China some 13,500 to 8,200 years ago; African rice was domesticated in Africa about 3,000 years ago. Rice has become commonplace in many cultures worldwide; in 2023, 800 million tons were produced, placing it third after sugarcane and maize. Only some 8% of rice is traded internationally. China, India, and Indonesia are the largest consumers of rice. A substantial amount of the rice produced in developing nations is lost after harvest through factors such as poor transport and storage. Rice yields can be reduced by pests including insects, rodents, and birds, as well as by weeds, and by List of rice diseases, diseases such as rice blast. Traditional rice polyc ...

Giant Bushy-tailed Cloud Rat
The giant bushy-tailed cloud rat or Luzon bushy-tailed cloud rat (''Crateromys schadenbergi'') is a large, endangered species of rodent in the family Muridae. It is only found in pine and mossy forest at altitudes of in the Central Cordillera of Luzon, the Philippines.Field Museum of Natural History (2010). Crateromys schadenbergi.' Synopsis of Philippine Mammals. Accessed June 10, 2011 Relatively little is known about its behavior, but it is nocturnal, mainly arboreal and feeds on various types of vegetation. It is rarer than the northern Luzon giant cloud rat, a shorter-haired species that mainly occurs at lower elevations, but locally the giant bushy-tailed cloud rat remains moderately common in oak-pine forest. The primary threats are hunting and habitat loss. The appearance of the giant bushy-tailed cloud rat has been described as spectacular, and it appears to be an equivalent of large tropical tree squirrels Tree squirrels are the members of the squirrel family (Sc ...
