| arbovirus surveillance in florida: wild vertebrate studies 1965-1974. | wildlife species from 38 of florida's 67 counties were surveyed over a 10 year period for the presence of antibody to the five major arboviruses circulating in the state. the routine screening of 7891 sera from wild birds and mammals via the hemagglutination-inhibition (h1) test with selected reactors subjected to serum neutralization testing has 1) provided information regarding geographic distribution and seasonality of circulation of these viruses 2) identified enzootic foci of infection and ... | 1975 | 1152173 |
| organochlorine residues in eggs of loggerhead and green sea turtles nesting at merritt island, florida--july and august 1976. | eggs from nine clutches of loggerhead turtles (caretta caretta) and two clutches of green turtles (chelonia mydas) were collected as they were laid on merritt island, florida. eggs were incubated, frozen, and analyzed for organochlorines. levels of dde and pcb, the major contaminants, averaged less than 0.08 ppm in loggerhead eggs and were even lower in green turtle eggs. these concentrations are far below levels thought to be potentially harmful. loggerhead eggs were frozen after 43-52 days inc ... | 1980 | 6775282 |
| redescription of hapalotrema mistroides (monticelli, 1896) and hapalotrema synorchis luhman, 1935 (digenea: spirorchidae), with comments on other species in the genus. | hapalotrema mistroides (monticelli, 1896) stiles and hassall, 1908 and hapalotrema synorchis luhman, 1935 are redescribed using specimens from the loggerhead turtle. caretta caretta (l.). the redescription of h. mistroides is based on specimens collected by looss and described as hapalotrema constrictum leared, 1862 and renamed hapalotrema loossi price, 1934, which is now considered a junior synonym of h. mistroides. hapalotrema orientalis takeuti, 1942 is considered a junior synonym of hapalotr ... | 1998 | 9645863 |
| association of herpesvirus with fibropapillomatosis of the green turtle chelonia mydas and the loggerhead turtle caretta caretta in florida. | sea turtle fibropapillomatosis (fp) is a disease marked by proliferation of benign but debilitating cutaneous fibropapillomas and occasional visceral fibromas. transmission experiments have implicated a chloroform-sensitive transforming agent present in filtered cell-free tumor homogenates in the etiology of fp. in this study, consensus primer pcr methodology was used to test the association of a chelonian herpesvirus with fibropapillomatosis. fibropapilloma and skin samples were obtained from 1 ... | 1999 | 10494499 |
| survey of florida green turtles for exposure to a disease-associated herpesvirus. | a recently developed enzyme-linked immunosorbent assay (elisa) was used to assess exposure of florida wild green turtles chelonia mydas to letv, the herpesvirus associated with lung-eye-trachea disease (letd). plasma samples from 329 wild juvenile green turtles netted in the indian river lagoon, along the sebastian reef, or in the trident basin (indian river and brevard counties, florida) were tested by elisa for the presence of antibodies to letv. plasma samples from 180 wild juvenile green tur ... | 2001 | 11804414 |
| perfluorinated compounds in the plasma of loggerhead and kemp's ridley sea turtles from the southeastern coast of the united states. | perfluorinated compounds (pfcs) have been measured in blood of humans and wildlife and are considered globally distributed contaminants. we examined 12 pfcs in the plasma of 73 loggerhead sea turtles (caretta caretta) and 6 kemp's ridley sea turtles (lepidochelys kempii) captured from inshore waters of core sound, north carolina (nc), and offshore waters of south carolina, georgia, and florida (sc-fl). perfluorooctanesulfonate (pfos) and perfluorooctanoic acid (pfoa) were the dominant compounds, ... | 2005 | 16382930 |
| temporal and spatial trends of perfluorinated compounds in juvenile loggerhead sea turtles (caretta caretta) along the east coast of the united states. | perfluorinated compounds (pfcs) are globally distributed persistent environmental contaminants. this study provides temporal trends as well as large-scale spatial trends of pfc concentrations in threatened juvenile loggerhead sea turtles near or from florida bay (fl bay), cape canaveral (fl), charleston (sc), core sound (nc), and chesapeake bay (md). pfcs were extracted from 163 plasma and serum samples using solid-phase extraction and quantified with lc-ms/ms. concentrations of six compounds si ... | 2010 | 20521819 |
| multiple paternity in loggerhead turtle (caretta caretta) nests on melbourne beach, florida: a microsatellite analysis. | many aspects of sea turtle biology are difficult to measure in these enigmatic migratory species, and this lack of knowledge continues to hamper conservation efforts. the first study of paternity in a sea turtle species used allozyme analysis to suggest multiple paternity in loggerhead turtle (caretta caretta) clutches in australia. subsequent studies indicated that the frequency of multiple paternity varies from species to species and perhaps location to location. this study examined fine-scale ... | 2002 | 11856428 |
| organochlorine, pcb, pah, and metal concentrations in eggs of loggerhead sea turtles (caretta caretta) from northwest florida, usa. | composite samples of unhatched and physically unaltered loggerhead sea turtle, caretta caretta, eggs collected from 20 nests along northwest florida were analyzed for organochlorine pesticides (ocps), polychlorinated biphenyls (pcbs), polycyclic aromatic hydrocarbons (pahs), and metals. chemical analyses revealed that turtle eggs contained detectable amounts of metals, pahs, and pcbs. only one ocp, p,p'-ddd, was detected, and its presence was restricted to eggs from two nesting sites. none of th ... | 2000 | 11069014 |
| size-dependent, sex-dependent, and seasonal changes in insulin-like growth factor i in the loggerhead sea turtle (caretta caretta). | this study examines size-dependent, sex-dependent, and seasonal fluctuations in plasma insulin-like growth factor-i (igf-i) concentrations in loggerhead sea turtles (caretta caretta). loggerhead turtles (n = 158) were captured in shrimp trawler nets during a 12-month survey in cape canaveral channel, florida. plasma samples were analyzed using a validated heterologous radioimmunoassay. large turtles (> 75 cm straight-line carapace length) had significantly higher plasma igf-i concentrations than ... | 1995 | 7635276 |
| breeding sex ratio and population size of loggerhead turtles from southwestern florida. | species that display temperature-dependent sex determination are at risk as a result of increasing global temperatures. for marine turtles, high incubation temperatures can skew sex ratios towards females. there are concerns that temperature increases may result in highly female-biased offspring sex ratios, which would drive a future sex ratio skew. studying the sex ratios of adults in the ocean is logistically very difficult because individuals are widely distributed and males are inaccessible ... | 2018 | 29370223 |
