It is only found in Luzon, the Philippines.[1] AppearanceThis very large rodent weighs {{convert|1.9|-|2.6|kg|lb|abbr=on}} and is {{convert|75|-|77|cm|in|round=0.5|abbr=on}} long.[3] The colour of its relatively long pelage, which also covers the tail, is highly variable, but usually it is mostly very pale grey-brown or white with some dark brown or black patches.[3] They often have a black mask and collar, but can also be entirely white.[3][2] The northern Luzon giant cloud rat has a slender tail, while the southern giant slender-tailed cloud rat, the only other species in the genus Phloeomys, has a bushy tail.[2] Distribution and habitatThe northern Luzon giant cloud rat is only found in northern and central part of Luzon, the Philippines.[1] It is found in at least 12 provinces.[2] The northern Luzon giant cloud rat prefers forest and scrub, but also occurs in degraded habitats such as plantations.[1] It occurs from sea level to an altitude of about {{convert|2200|m|ft}}.[3] In some areas it overlaps with the rarer giant bushy-tailed cloud rat, but that species mainly occurs at higher altitudes than the northern Luzon giant cloud rat.[3] BehaviorThe northern Luzon giant cloud rat is nocturnal and feeds on various types of vegetation.[3] Because of its relatively large size, it does not enter traditional small-mammal traps and this has limited research in the species.[4] ReproductionNorthern Luzon giant cloud rats often live in pairs with one or two dependent young.[2] They give birth in hollow boles of trees (standing or fallen) or in burrows in the ground.[2] The sperm head of northern Luzon giant cloud rat has a short apical hook, with the sperm tail attached off-center basally.[5] The tail of the sperm is about 127 µm long.[5] Conservation statusThe northern Luzon giant cloud rat can cause extensive damage to rice crops and are sometimes considered a pest.[6] They are regularly hunted for food in the Sierra Madre.[7] It has been extirpated from some regions because of hunting,[3] but overall it appears to be able to withstand hunting pressure and in general it remains common and widespread.[1] References1. ^1 2 3 4 {{IUCN2010.4|assessor=Heaney, L.|assessor2=Balete, D.|assessor3=Rosell-Ambal, G.|assessor4=Tabaranza, B.|assessor5=Ong, P.|assessor6=Ruedas, L.|assessor7=Oliver, W.|last-assessor-amp=yes|year=2008|id=17004|title=Phloeomys pallidus|downloaded=10 June 2011}} {{Murinae (Oenomys–Pithecheir)}}{{Taxonbar|from=Q1761999}}2. ^1 2 3 4 {{Cite journal|last=Oliver|display-authors=etal|year=1993|title=Cloud rats in the Philippines--preliminary report on distribution and status|url=|journal=Oryx|volume=27|pages=41–48|via=|doi=10.1017/s0030605300023942}} 3. ^1 2 3 4 5 6 {{Cite web| url=http://archive.fieldmuseum.org/philippine_mammals/species/SP_164.asp| title=Phloeomys pallidus| date=2010| publisher=Field Museum of Natural History, Synopsis of Philippine Mammals|access-date=10 June 2011}} 4. ^{{Cite journal|last=Duya|display-authors=etal|year=2011|title=Chapter 4: Diversity of Small Mammals in Montane and Mossy Forests on Mount Cetaceo, Cagayan Province, Luzon|url=|journal=Fieldiana: Life and Earth Sciences|volume=2|pages=88–95|via=|doi=10.3158/2158-5520-2.1.88}} 5. ^1 {{Cite journal|last=Breed|display-authors=etal|year=2010|title=The spermatozoon of the Old Endemic Australo-Papuan and Philippine rodents--its morphological diversity and evolution|url=|journal=Acta Zoologica|volume=91|pages=279–294|via=|doi=10.1111/j.1463-6395.2009.00407.x}} 6. ^{{Cite book|title=Philippine Rats: ecology and management|author1=Singleton|author2=Ravindra|author3=Sebastian|last-author-amp=yes|publisher=PhilRice|year=2008|isbn=|location=|pages=|via=}} 7. ^{{Cite journal|last=Duya|display-authors=etal|year=2007|title=Report on a Survey of Mammals of the Sierra Madre Rance, Luzon Island, Philippines|url=|journal=Banwa|volume=4|pages=41–68|via=}} 7 : Rats of Asia|Phloeomys|Endemic fauna of the Philippines|Fauna of Luzon|Rodents of the Philippines|Mammals described in 1890|Taxonomy articles created by Polbot |
