The Oaxaca giant deer mouse (Megadontomys cryophilus) is a species of rodent in the family Cricetidae. It is found only in Mexico.
Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Its members are formally referred to as carnivorans, though some species are omnivorous, such as raccoons and bears, and quite a few species such as pandas are specialized herbivores. The word "carnivore" is derived from Latin carō "flesh" and vorāre "to devour" and refers to any meat-eating organism. The order Carnivora is the fifth largest order of mammals and one of the more successful members of the group, as it comprises at least 279 species.
Felidae is a family of mammals in the order Carnivora, colloquially referred to as cats, and constitutes a clade. A member of this family is also called a felid. The term "cat" refers both to felids in general and specifically to the domestic cat.
Panthera is a genus within the family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger, lion, jaguar, and leopard on the basis of common cranial features. Results of genetic analysis indicate that the snow leopard also belongs to the Panthera, a classification that was accepted by IUCN Red List assessors in 2008.
A mongoose is a small terrestrial carnivorous mammal belonging to the family Herpestidae. This family is currently split into two subfamilies, the Herpestinae and the Mungotinae. The Herpestinae comprises 23 living species that are native to southern Europe, Africa and Asia, whereas the Mungotinae comprises 11 species native to Africa. The Herpestidae originated about 21.8 ± 3.6 million years ago in the Early Miocene and genetically diverged into two main genetic lineages between 19.1 and 18.5 ± 3.5 million years ago.
The Neotominae are a subfamily of the family Cricetidae. They consist of four tribes, 16 genera, and many species of New World rats and mice, predominantly found in North America. Among them are the well-known deer mice, white-footed mice, packrats, and grasshopper mice.
Batomys is a genus of rodent endemic to the Philippines. It has six described species.
Schizosaccharomyces is a genus of fission yeasts. The most well-studied species is S. pombe. At present four Schizosaccharomyces species have been described. Like the distantly related Saccharomyces cerevisiae, S. pombe is a significant model organism in the study of eukaryotic cell biology. It is particularly useful in evolutionary studies because it is thought to have diverged from the Saccharomyces cerevisiae lineage between 300 million and 1 billion years ago, and thus provides an evolutionarily distant comparison.
Isthmomys is a genus of rodent in the family Cricetidae, belonging to the tribe Reithrodontomyini. Species are:
Megadontomys is a genus of rodent in the family Cricetidae, found in Mexico. It contains the following species:
Nelson's giant deer mouse is a species of rodent in the family Cricetidae. It is found only in Mexico.
Thomas's giant deer mouse is a species of rodent in the family Cricetidae. It is found only in Mexico.
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined.
The giant island deer mouse became extinct approximately 8000 years BP and lived during the late Pleistocene on California’s Channel Islands.
Guy Graham Musser was an American zoologist. His main research is in the field of the rodent subfamily Murinae, in which he has described many new species.
Gigantolaelaps is a genus of mites in the family Laelapidae. It is found in the fur of cricetid rodents, most often from the tribe Oryzomyini, from South America north to the southern United States. They are large (>1 mm) and darkly colored and have a complex life cycle.
The Central Highlands, Central High Plateau, or Hauts-Plateaux are a mountainous biogeographical region in central Madagascar. They include the contiguous part of the island's interior above 800 m (2,600 ft) altitude. The Central Highlands are separated from the Northern Highlands of the northern tip of Madagascar by a low-lying valley, the Mandritsara Window, which has apparently acted as a barrier to dispersal for species in the highlands, leading to species pairs such as Voalavo gymnocaudus and Voalavo antsahabensis in the Northern and Central Highlands. Species restricted to the Central Highlands include the bats Miniopterus manavi and Miniopterus sororculus; the rodents Brachyuromys betsileoensis and Voalavo antsahabensis; the tenrecs Hemicentetes nigriceps and Oryzorictes tetradactylus; and the lemur Cheirogaleus sibreei. Because of the continuous habitat of the Central Highlands, there is little local endemism, unlike the Northern Highlands.
