Aonchotheca Forresteri
''Aonchotheca forresteri'' is a parasitic nematode that infects the marsh rice rat (''Oryzomys palustris'') in Florida. Occurring mainly in adults, it inhabits the stomach. It is much more common during the wet season, perhaps because its unknown intermediate host is an earthworm that only emerges when it rains. The worm was discovered in 1970 and formally described in 1987. Originally classified in the genus ''Capillaria'', it was reclassified in '' Aonchotheca'' in 1999. ''A. forresteri'' is small and narrow-bodied, with a length of 13.8 to 19.4 mm in females and 6.8 to 9.2 mm in males. Similar species such as '' A. putorii'' differ in features of the alae and spicule (organs in the male), the size of the female, and the texture of the eggs. Taxonomy ''Aonchotheca forresteri'' was discovered during a survey of the endoparasites of Florida marsh rice rats (''Oryzomys palustris'') by John Kinsella from 1970 to 1972,Forrester, 1992, p. 100 and is one of s ...

Parasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted parasitism, parasitoidism, and micropreda ...

Oryzomys Palustris Paynes
''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (''O. palustris'') of the United States and '' O. couesi'' of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name ''Oryzomys'' was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in ''Oryzomys''. Species of ''Oryzomys'' are medium-sized rats with long, coarse fur. The upperparts are gray to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levy County
Levy County is a county located on the Gulf coast and in the northern part of the U.S. state of Florida. As of the 2020 census, the population was 42,915. Its county seat is Bronson. History Levy County was created in 1845, after the Seminole Wars. It was named for David Levy Yulee, a planter elected in 1841 as the state's territorial delegate to the US House of Representatives, where he served two terms. Levy provided for long-term development in the state by constructing the first railroad across Florida, the Florida Railroad, linking the deep-water ports of Fernandina (Port of Fernandina) on the Atlantic Ocean and Cedar Key on the Gulf of Mexico. The Rosewood Massacre occurred in Levy County in the first week of January 1923. White citizens from the nearby town of Sumner, reacting to a what turned out to be a false accusation that a black man raped a white woman, burned the predominantly black town of Rosewood to the ground and brutally murdered several of Rosewood's bla ...

Cedar Key
Cedar Key is a city in Levy County, Florida, United States. The population was 702 at the 2010 census. The Cedar Keys are a cluster of islands near the mainland. Most of the developed area of the city has been on Way Key since the end of the 19th century. The Cedar Keys are named for the eastern red cedar ''Juniperus virginiana'', once abundant in the area. History Early While evidence suggests human occupation as far back as 500 BC, the first maps of the area date to 1542, when it was labeled "Las Islas Sabines" by a Spanish cartographer. An archaeological dig at Shell Mound, north of Cedar Key, found artifacts dating back to 500 BC in the top of the mound. The only ancient burial found in Cedar Key was a 2,000-year-old skeleton found in 1999. Arrow heads and spear points dating from the Paleo period (12,000 years old) were collected by Cedar Key historian St. Clair Whitman and are displayed at the Cedar Key Museum State Park. Followers of William Augustus Bowles, self-decl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alachua County
Alachua County ( ) is a county in the north central portion of the U.S. state of Florida. As of the 2020 census, the population was 278,468. The county seat is Gainesville, the home of the University of Florida since 1906, when the campus opened with 106 students. Alachua County is part of the Gainesville Metropolitan Statistical Area. The county is known for its diverse culture, local music, and artisans. Much of its economy revolves around the university, which had nearly 55,000 students in the fall of 2016. History Early history The first people known to have entered the area of Alachua County were Paleo-Indians, who left artifacts in the Santa Fe River basin before 8000 BCE. Artifacts from the Archaic period (8000 - 2000 BCE) have been found at several sites in Alachua County. Permanent settlements appeared in what is now Alachua County around 100 CE, as people of the wide-ranging Deptford culture developed the local Cades Pond culture. The Cades Pond culture gave way ...

Paynes Prairie
Paynes Prairie Preserve State Park is a Florida State Park, encompassing a savanna in Alachua County, Florida lying between Micanopy and Gainesville. It is also a U.S. National Natural Landmark. It is crossed by both I-75 and U.S. 441 (which has a scenic outlook ramp). It is in the center of the Paynes Prairie Basin. The basin's primary source of drainage is Alachua Sink. During occasional wet periods, the basin will become full. A notable period occurred from 1871 to 1891 when the Alachua Sink was temporarily blocked. During this period, shallow draft steamboats were a frequent sight on Alachua Lake in the center of the prairie. The region was also historically known as the Alachua Savannah. Its drainage has been modified by several canals. Since 1927, Camps Canal has linked the basin to the River Styx which leads to Orange Lake and eventually the Atlantic Ocean through the St. Johns River. That reduced the basins water intake by half. Additional changes to the prairie's envi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chipmunk
Chipmunks are small, striped rodents of the family Sciuridae. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia. Taxonomy and systematics Chipmunks may be classified either as a single genus, ''Tamias'', or as three genera: ''Tamias'', of which the eastern chipmunk (''T. striatus'') is the only living member; ''Eutamias'', of which the Siberian chipmunk (''E. sibiricus'') is the only living member; and ''Neotamias'', which includes the 23 remaining, mostly western North American, species. These classifications were treated as subgenera due to the chipmunks' morphological similarities. As a result, most taxonomies over the twentieth century have placed the chipmunks into a single genus. However, studies of mitochondrial DNA show that the divergence between each of the three chipmunk groups is comparable to the genetic differences between ''Marmota'' and ''Spermophilus'', so the three genera classifications have b ...

Cloaca
In animal anatomy, a cloaca ( ), plural cloacae ( or ), is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles and birds, and a few mammals ( monotremes, tenrecs, golden moles, and marsupial moles), have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. Excretory openings with analogous purpose in some invertebrates are also sometimes referred to as cloacae. Mating through the cloaca is known as cloacal copulation, commonly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes. Etymology The word is from the Latin verb ''cluo'', "(I) cleanse", thus the noun ''cloaca'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anus
The anus (Latin, 'ring' or 'circle') is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, the residual semi-solid waste that remains after food digestion, which, depending on the type of animal, includes: matter which the animal cannot digest, such as bones; Summary at food material after the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts. Amphibians, reptiles, and birds use the same orifice (known as the cloaca) for excreting liquid and solid wastes, for copulation and egg-laying. Monotreme mammals also have a cloaca, which is thought to be a feature inherited from the earliest amniotes via the therapsids. Marsupials have a single orifice for excreting both solids and liquids and, in females, a separate vagina for reproduction. Female placental mamm ...

Vulva
The vulva (plural: vulvas or vulvae; derived from Latin for wrapper or covering) consists of the external sex organ, female sex organs. The vulva includes the mons pubis (or mons veneris), labia majora, labia minora, clitoris, bulb of vestibule, vestibular bulbs, vulval vestibule, urinary meatus, the Vagina#Vaginal opening and hymen, vaginal opening, hymen, and Bartholin's gland, Bartholin's and Skene's gland, Skene's vestibular glands. The urinary meatus is also included as it opens into the vulval vestibule. Other features of the vulva include the pudendal cleft, sebaceous glands, the urogenital triangle (anterior part of the perineum), and pubic hair. The vulva includes the entrance to the vagina, which leads to the uterus, and provides a double layer of protection for this by the folds of the outer and inner labia. Pelvic floor muscles support the structures of the vulva. Other muscles of the urogenital triangle also give support. Blood supply to the vulva comes from the t ...
