| morbidity and mortality factors in key deer (odocoileus virginianus clavium). | the population health of endangered key deer (odocoileus virginianus clavium) was monitored from 10 february 1986 to 28 september 2000 by necropsy of animals that were killed by vehicles, euthanized because of terminal injuries or disease conditions, or found dead. the predominant mortality factor during the period was collision with motor vehicles; however, several infectious diseases were diagnosed, including infections with arcanobacterium pyogenes, haemonchus contortus, salmonella spp., and ... | 2002 | 12528433 |
| paratuberculosis in key deer (odocoileus virginianus clavium). | paratuberculosis was diagnosed in an endangered key deer (odocoileus virginianus clavium) in november 1996. between 10 april 1997 and 28 september 2000, the key deer population was monitored for infection with mycobacterium avium subsp. paratuberculosis by necropsy of available carcasses (n = 170), fecal cultures, and serology. one additional clinically affected key deer was discovered in july 1998, and m. avium subsp. paratuberculosis was cultured from the feces of one live, asymptomatic deer. ... | 2002 | 12528439 |
| seed dispersal by the florida box turtle (terrapene carolina bauri) in pine rockland forests of the lower florida keys, united states. | seed dispersal by animals is one of the most important plant-animal mutualisms, but saurochory, the dispersal of seeds by reptiles, has received little attention. we investigated the role of the florida box turtle (terrapene carolina bauri) as a seed dispersal agent in pine rockland forests of the lower florida keys and examined the effect of turtle digestion on seed germination. we obtained seeds of 11 species with fleshy fruits and 2 species with non-fleshy fruits (a grass and legume) from the ... | 2004 | 14685845 |
| distribution of mycobacterium avium subspecies paratuberculosis in the lower florida keys. | johne's disease, a fatal and contagious gastrointestinal infection caused by mycobacterium avium subsp. paratuberculosis (map), was first diagnosed in an endangered florida key deer (odocoileus virginianus clavium) in 1996 and later in six additional key deer deaths from 1998 to 2004. we investigated the geographic distribution of map in the lower florida keys from february 2005 through may 2006 via collection of blood and fecal pellets from 51 live-captured deer, collection of 550 fecal samples ... | 2008 | 18689642 |
| persistence of mycobacterium avium subspecies paratuberculosis in endangered florida key deer and key deer habitat. | mycobacterium avium subsp. paratuberculosis (map) was first reported in the endangered key deer (odocoileus virginianus clavium) in 1996 on big pine key, florida, usa. by 2008, eight additional map-positive key deer had been identified on big pine key and the nearby newfound harbor keys. this study was conducted to determine if map was still present in key deer and whether natural or man-made freshwater sources were contaminated with map. between november 2009 and september 2012, map was isolate ... | 2014 | 24506424 |
| mosquito fauna of wilderness islands within the national key deer refuge and the great white heron national wildlife refuge, monroe county, florida. | dry ice-baited light traps, counts of mosquitoes biting and landing on technicians, and larval surveillance were used to determine mosquito species abundance on annette key, little knockem-down key, little pine key, raccoon key, and the water keys, all of which are located offshore, within the national key deer refuge and great white heron national wildlife refuge in monroe county, fl. due to the close proximity of these wilderness islands to the inhabited islands of the florida keys, it is impo ... | 2010 | 20649123 |
| interisland dispersal of the black salt marsh mosquito, ochlerotatus taeniorhynchus (diptera: culicidae) in the florida keys. | mark-release-recapture experiments were conducted in 2001 and 2002 to determine whether ochlerotatus taeniorhynchus, black salt marsh mosquitoes, were dispersing from uninhabited islands in the key deer national wildlife refuge to inhabited islands within monroe county, florida. an estimated 1,658,000 mosquitoes were marked during 2001, and an estimated 300,000 mosquitoes were marked during 2002. recapture rates were 0.0061% and 0.0117%, respectively. oc. taeniorhynchus disperse from uninhabited ... | 2006 | 17304926 |
| prion protein gene (prnp) sequences suggest differing vulnerability to chronic wasting disease for florida key deer (odocoileus virginianus clavium) and columbian white-tailed deer (o. v. leucurus). | chronic wasting disease (cwd) is a fatal, highly transmissible spongiform encephalopathy caused by an infectious prion protein. cwd is spreading across north american cervids. studies of the prion protein gene (prnp) in white-tailed deer (wtd; odocoileus virginianus) have identified non-synonymous substitutions associated with reduced cwd frequency. because cwd is spreading rapidly geographically, it may impact cervids of conservation concern. here, we examined the genetic vulnerability to cwd o ... | 2020 | 32945850 |
| genetic and evolutionary considerations of the chronic wasting disease - human species barrier. | transmissible spongiform encephalopathies can jump species barriers. in relatively few cases is the possible route of transmission thought to be known, mostly involving humans, cattle and sheep. it is thought that sheep might be the cause of bovine spongiform encephalopathy (bse) and chronic wasting disease (cwd) in cervids, and that humans might have gotten prion disease (e.g., vcjd) from eating meat from bse+ cows. a looming societal question is whether humans will acquire a prion disease from ... | 2020 | 32731042 |
| geographic variation in the prnp gene and its promoter, and their relationship to chronic wasting disease in north american deer. | prnp genotypes, number of octarepeats (phgggwgq) and indels in the prnp promoter can influence the progression of prion disease in mammals. we found no relationship between presence of promoter indels in white-tailed deer and mule deer from nebraska and cwd presence. white-tailed deer with the 95 h allele and g20d mule deer were more likely to be cwd-free, but unlike other studies white-tailed deer with the 96s allele(s) were equally likely to be cwd-free. we provide the first information on prn ... | 2020 | 32715865 |
| mortality and cholinesterase inhibition in butterflies following aerial naled applications for mosquito control on the national key deer refuge. | natural resource managers are concerned about the impacts of aerial ultra-low volume spray (ulv) of insecticides for mosquito control (i.e., mosquito adulticides) and seek science-driven management recommendations that reduce risk but allow vector control for nearby human populations. managers at the national key deer refuge (florida keys, fl) are concerned for ulv effects upon conservation efforts for imperiled butterflies (florida leafwing [anaea troglodyta floridalis] and bartram's hairstreak ... | 2020 | 32613299 |
| use of a multiagency approach to eradicate new world screwworm flies from big pine key, florida, following an outbreak of screwworm infestation (september 2016-march 2017). | on september 30, 2016, the us national veterinary services laboratory confirmed an autochthonous case of new world screwworm infestation in a key deer (odocoileus virginianus clavium) from big pine key, fla. this case marked the first identification of a sustained and reproducing population of new world screwworm flies in the united states since 1966. multiple federal, state, and local government agencies collaborated to initiate a response to the outbreak. efforts were successful in eradicating ... | 2019 | 31573861 |
| screwworm (diptera: calliphoridae) in the united states: response to and elimination of the 2016-2017 outbreak in florida. | eradicating screwworm, cochliomyia hominivorax (coquerel), from continental north american via the sterile insect technique has provided huge economic benefit to livestock producers by eliminating screwworm myiasis. after confirmatory identification of fly samples from infested deer by the usda national veterinary services laboratory on september 30, 2016, an alert was issued that screwworm myiasis was discovered in the florida keys. personnel from usda animal and plant health inspection service ... | 2018 | 29722869 |
| co-occurrence dynamics of endangered lower keys marsh rabbits and free-ranging domestic cats: prey responses to an exotic predator removal program. | the lower keys marsh rabbit (sylvilagus palustris hefneri) is one of many endangered endemic species of the florida keys. the main threats are habitat loss and fragmentation from sea-level rise, development, and habitat succession. exotic predators such as free-ranging domestic cats (felis catus) pose an additional threat to these endangered small mammals. management strategies have focused on habitat restoration and exotic predator control. however, the effectiveness of predator removal and the ... | 2018 | 29721278 |
| a vulnerability assessment of 300 species in florida: threats from sea level rise, land use, and climate change. | species face many threats, including accelerated climate change, sea level rise, and conversion and degradation of habitat from human land uses. vulnerability assessments and prioritization protocols have been proposed to assess these threats, often in combination with information such as species rarity; ecological, evolutionary or economic value; and likelihood of success. nevertheless, few vulnerability assessments or prioritization protocols simultaneously account for multiple threats or cons ... | 2013 | 24260447 |
| larviciding offshore islands reduces adulticidal treatment of populated areas adjacent to national wildlife refuges. | the florida keys mosquito control district has conducted larvicide missions on uninhabited offshore islands of the great white heron national wildlife refuge and the national key deer refuge since 2003. the objective of these missions is to reduce the need to apply adulticides on nearby populated islands where private lands are interspersed with refuge lands that support a diverse assemblage of native butterflies and insect-pollinated plants on big pine key, no name key, little torch key, middle ... | 2011 | 22329274 |
