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 ...

Parasite
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding 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), ...

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 in the North central Florida part of the U.S. state of Florida. As of the 2020 census, the population was 42,915. Its county seat is Bronson. It has been included in the Gainesville, Florida Metropolitan Statistical Area since 2018. History Levy County was created in 1845, after the Seminole Wars, and became Florida's 27th county. It was named for David Levy Yulee, a slave owner 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 original county seat of Levy County was located in a neighborhood locally known as Sodom. This concerned the county commission so much that in April 1854 they changed the name to “Mount Pleasan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cedar Key
Cedar Key is a city in Levy County, Florida, United States. As of the 2020 census, its population was 687, down from 702 at the 2010 census. It is part of the Gainesville, Florida Metropolitan Statistical Area. The Cedar Keys are a cluster of islands near the mainland. Most of the developed area for the City of Cedar Key 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. The city was impacted by Hurricane Helene on September 26, 2024, which caused a 10-foot storm surge that broke the record set during Hurricane Idalia in August 2023. History Early While evidence suggests human occupation as far back as 500 BC, the first maps of the area date to 1542, when a cartographer from Spain labeled it "Las Islas Sabines" (which means "The Cedar Islands" in Spanish). An archaeological dig at Shell Mound, north of Cedar Key, found artifacts dating back to 500 BC in the top of ... [...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. History Prehistory and early European settlements 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 BC. Artifacts from the Archaic period (8000 - 2000 BC) have been found at several sites in Alachua County. Permanent settlements appeared in what is now Alachua County around 100 AD, as people of the wide-ranging Deptford culture developed the local Cades Pond culture. The Cades Pond culture gave way to the Alachua culture around 600 AD. The Timucua-speaking Potano tribe lived in the Alachua culture area in the 16th century, when the Spanish entered Florida. The Potano were incorporated by the colonists in the Spanish mission system, but new infectious diseases, reb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 basin's water intake by half. Additional changes to the prairie's e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chipmunk
Chipmunks are small, striped rodents of subtribe Tamiina. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia. Taxonomy and systematics Chipmunks are classified as four 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; ''Nototamias'', which consists of three extinct species, 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. Joseph C. Moore reclassified chipmunks to form a subtribe Tamiina in a 1959 study, and this classification has been supported by studies of mitochondrial DNA. The common name originally may have been spelled "chitmunk", fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cloaca
A cloaca ( ), : cloacae ( or ), or vent, is the rear orifice that serves as the only opening for the digestive (rectum), reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles, birds, cartilaginous fish and a few mammals ( monotremes, afrosoricids, and marsupial moles, etc.) have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have separate orifices for evacuation and reproduction. Excretory openings with analogous purpose in some invertebrates are also sometimes called cloacae. Mating through the cloaca is called cloacal copulation and cloacal kissing. 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'', " sewer, drain" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anus
In mammals, invertebrates and most fish, the anus (: anuses or ani; from Latin, 'ring' or 'circle') is the external body orifice at the ''exit'' end of the digestive tract (bowel), i.e. the opposite end from the mouth. Its function is to facilitate the defecation, expulsion of wastes that remain after digestion. Bowel contents that pass through the anus include the gaseous flatus and the semi-solid feces, which (depending on the type of animal) include: indigestible matter such as bones, hair pellet (ornithology), pellets, endozoochory, endozoochorous seeds and gastrolith, digestive rocks; Summary at residual food material after the digestible nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; excretion, excreted metabolites like bilirubin-containing bile; and dead mucosal epithelia or excess gut bacteria and other endosymbionts. Passage of feces through the anus is typically controlled by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulva
In mammals, the vulva (: vulvas or vulvae) comprises mostly external, visible structures of the female sex organ, genitalia leading into the interior of the female reproductive tract. For humans, it includes the mons pubis, labia majora, labia minora, clitoris, vulval vestibule, vestibule, urinary meatus, vaginal introitus, hymen, and openings of the vestibular glands (Bartholin's gland, Bartholin's and Skene's gland, Skene's). The folds of the outer and inner labia provide a double layer of protection for the vagina (which leads to the uterus). 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 three pudendal arteries. The internal pudendal veins give drainage. Lymphatic vessel#Afferent vessels, Afferent lymph vessels carry lymph away from the vulva to the inguinal lymph nodes. The nerves that supply the vulva are the pudendal nerve, perineal nerve, ilioinguinal nerve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
