Saxatilomys
''Saxatilomys paulinae'' is a species of murid rodent native to central Laos and Vietnam, separated to a monotypic genus ''Saxatilomys''. It was first discovered in the Khammouan Limestone National Biodiversity Conservation Area in Khammouan Province, Laos, and also been found in the Vietnamese province of Quang Bình. It is the only known species in the genus ''Saxatilomys''. The genus name is derived from the Latin ''saxatilis'', meaning "among the rocks" and the Greek ''mys'', meaning mouse or rat. Description It resembles, and is likely closely related to, species in the genera ''Niviventer'' and ''Chiromyscus''. ''Saxatilomys'' is distinguished from these and other Indomalayan genera by "semispinous dark gray upperparts, dark frosted gray underparts, large, extremely bulbous footpads, and a combination of derived and primitive cranial and dental traits". Habitat It is thought to be petricolous and has only been observed in forested, rocky limestone Limestone ( calci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World Rats And Mice
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial placental mammals. They have also been introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangerment and extinction of many native animals. Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently in ...

Khammouan Limestone National Biodiversity Conservation Area
The Phou Hin Poun National Biodiversity Conservation Area, formerly known as the Khammouane Limestone National Biodiversity Conservation Area, is one of 21 National Biodiversity Conservation Areas of the Lao People's Democratic Republic. Located in a limestone tower karst region of the Annamite Range in Khammouane Province, it is home to a number of rare or newly discovered species. National Biodiversity Conservation Areas are not protected by the government of Laos in any meaningful way; the budget for each is about $500. The human population of the NBCA is 29,603. Flora and fauna The vegetation of Phou Hin Poun National Biodiversity Conservation Area is shaped by its tropical savanna climate, and the rugged, cave-riddled and porous karst terrain. Over 50% of the landscape is estimated to be rocky outcroppings, and most of the rest is dry evergreen forest and scrubland. This diverse landscape is home to 113 species of mammal, 160 species of bird, 81 species of reptile, 47 species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guy Musser
Guy Graham Musser (August 10, 1936 – October 2019) was an American zoologist. His main research was in the field of the rodent subfamily Murinae, in which he has described many new species. Musser was born in Salt Lake City, Utah. He attended elementary and secondary public schools until 1955 and in 1967 obtained a PhD at the University of Michigan with a thesis about the taxonomy of the Mexican gray squirrel (''Sciurus aureogaster''). In 1966 he joined the American Museum of Natural History where he became curator of mammals. Since his retirement in 2002 he is curator emeritus. In the 1960s and 1970s he published numerous articles on squirrels, Neotominae and Murinae. In the 1970s he conducted a three-year expedition to the Indonesian island of Sulawesi where he discovered several new mice and rat species. The results of this expedition are still not fully published. In the early 1980s he published some of his most important works including ''Notes on systematics of Indo-Mal ...

Muridae
The Muridae, or murids, are the largest family of rodents and of mammals, containing approximately 1,383 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia. The name Muridae comes from the Latin ' (genitive '), meaning "mouse", since all true mice belong to the family, with the more typical mice belonging to the genus '' Mus''. Distribution and habitat Murids are found nearly everywhere in the world, though many subfamilies have narrower ranges. Murids are not found in Antarctica or many oceanic islands. Although none of them are native to the Americas, a few species, notably the house mouse and black rat, have been introduced worldwide. Murids occupy a broad range of ecosystems from tropical forests to tundras. Fossorial, arboreal, and semiaquatic murid species occur, though most are terrestrial animals. The extensive list of niches filled by murids helps to explain their relative abundance. Diet and dentiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
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 New Zealand, 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/richochetal (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. Rabbits, hares, and pikas, whose i ...

Indomalayan
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia. Also called the Oriental realm by biogeographers, Indomalaya spreads all over the Indian subcontinent and Southeast Asia to lowland southern China, and through Indonesia as far as Sumatra, Java, Bali, and Borneo, east of which lies the Wallace line, the realm boundary named after Alfred Russel Wallace which separates Indomalaya from Australasia. Indomalaya also includes the Philippines, lowland Taiwan, and Japan's Ryukyu Islands. Most of Indomalaya was originally covered by forest, and includes tropical and subtropical moist broadleaf forests, with tropical and subtropical dry broadleaf forests predominant in much of India and parts of Southeast Asia. The tropical forests of Indomalaya are highly variable and diverse, with economically important trees, especially in the families Dipterocarpaceae and Fabaceae. Major ecolog ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
