Laelaps Oryzomydis
''Laelaps manguinhosi'' is a species of parasitic mite in the family Laelapidae. In the United States, it has been found on the marsh rice rat (''Oryzomys palustris'') in Florida, Texas, and South Carolina. Other recorded hosts include the sigmodontine rodents ''Scapteromys aquaticus'', ''Akodon azarae'', ''Oligoryzomys flavescens'', and ''Holochilus brasiliensis'' in Argentina and ''Oryzomys couesi'' and ''Handleyomys melanotis'' in Mexico. In Venezuela, it mainly infects the oryzomyines ''Holochilus sciureus'' and ''Nectomys'', but it has also been recorded on a variety of other mammals and even on a bird. A separate subspecies, ''Laelaps manguinhosi calvescens'', has been described from the ichthyomyine rodent ''Neusticomys venezuelae''.Furman, 1972, p. 24 See also *List of parasites of the marsh rice rat Notes References Literature cited *Estébanes-González, M.L., Sánchez-Hernández, C., Romero-Almaraz, M. de L. and Schnell, G.D. 2011Ácaros parásitos de roedores ...

Laelapidae
The Laelapidae are a family (biology), family of mites in the order Mesostigmata. The family is also referred to in the literature as Laelaptidae, which may be the correct spelling. Description Laelapidae have a shield covering all or most of the dorsal surface (holodorsal shield). Ventrally, there is a sternal shield with 3 pairs of Seta, setae, a tongue- or flask-shaped genital shield (greatly expanded in ''Ololaelaps'') with usually at least 1 pair of setae, and a small anal shield with 3 circumanal setae. The peritremes are typically long and the peritrematal shields often narrow. Ecology Laelapidae is the most ecologically diverse group of Mesostigmata. As of 2012, there were ten laelapid genera known to be free-living Predation, predators in soil, thirty-five that are Parasitism, ectoparasites on mammals (e.g. Rodent, rodents) and forty-three have species associated with arthropods. Laelapidae are the only family in superfamily Dermanyssoidea to include free-living pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animals Described In 1936
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

List Of Parasites Of The Marsh Rice Rat
A variety of parasites have been recorded from the marsh rice rat (''Oryzomys palustris''), a semiaquatic rodent found in the eastern and southern United States, north to New Jersey New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware ... and Kansas and south to Florida and Texas, and in Tamaulipas, far northeastern Mexico. Some of these parasites are endoparasites, internal parasites, while others are ectoparasites, external parasites. Parasitology, Parasitologist John Kinsella compared the endoparasites of marsh rice rats in a saltwater marsh at Cedar Key and a freshwater marsh at Paynes Prairie, both in Florida, in a 1988 study. He found a total of 45 species, a number unequaled in rodents. This may be related to the diverse habitats the rice rat uses and to its Omnivore, omnivorou ...

Nectomys
''Nectomys'' is a genus of rodent in the tribe Oryzomyini of family Cricetidae. Musser and Carleton, 2005. It is closely related to ''Amphinectomys'' and was formerly considered congeneric with ''Sigmodontomys''. It consists of five species, which are allopatrically distributed across much of South America: ''Nectomys grandis'' in montane Colombia; ''Nectomys palmipes'' on Trinidad and in nearby Venezuela, ''Nectomys apicalis'' in the western margins of the Amazon biome, ''Nectomys rattus'' in much of Amazonia, and ''Nectomys squamipes'' in the Atlantic Forest of Brazil. These species are generally semiaquatic In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water. Examples are given below. Semiaquatic animals Semiaquatic animals include: * Verte ..., are normally found near water, and are commonly called water rats.

Holochilus Sciureus
The Amazonian marsh rat (''Holochilus sciureus''), also known as the common marsh rat,Duff, A. and Lawson, A. 2004. ''Mammals of the World: A checklist''.

Oryzomyine
Oryzomyini is a tribe (taxonomy), tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern List of mammals of the United States, United States to the southernmost parts of List of mammals of South America, South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molar (tooth), molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', ''Oecomys'', and ''Oryzomys'' (w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oryzomys Couesi
''Oryzomys couesi'', also known as Coues's rice rat, is a semiaquatic rodent in the family Cricetidae occurring from southernmost Texas through Mexico and Central America into northwestern Colombia. It is usually found in wet habitats, such as marshes, but also lives in drier forests and shrublands. Weighing about , ''O. couesi'' is a medium-sized to large rat. The coarse fur is buff to reddish above and white to buff below. The hindfeet show some specializations for life in the water, such as reduced ungual tufts of hair around the digits. It has 56 chromosomes. There is much geographic variation in size, proportions, color, and skull features. ''Oryzomys couesi'' is active during the night and builds nests of vegetation that are suspended among reeds about above the ground. It is an excellent swimmer and dives well, but can also climb in vegetation. An omnivore, it eats both plant and animal food, including seeds and insects. It breeds throughout the year; females giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsh Rice Rat
The marsh rice rat (''Oryzomys palustris'') is a semiaquatic North American rodent in the family Cricetidae. It usually occurs in wetland habitats, such as swamps and salt marshes. It is found mostly in the eastern and southern United States, from New Jersey and Kansas south to Florida and northeasternmost Tamaulipas, Mexico; its range previously extended further west and north, where it may have been a commensalism, commensal in corn-cultivating communities. Weighing about , the marsh rice rat is a medium-sized rodent that resembles the common black rat, black and brown rat. The upperparts are generally gray-brown, but are reddish in many Florida populations. The feet show several specializations for life in the water. The skull is large and flattened, and is short at the front. John Bachman discovered the marsh rice rat in 1816, and it was formally described in 1837. Several subspecies have been described since the 1890s, mainly from Florida, but disagreement exists over their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
