| ticks parasitizing reptiles in the bahamas. | two species of reptile ticks, amblyomma dissimile koch and amblyomma torrei pérez vigueras (acari: ixodidae), are reported from the bahama islands for the first time. the widespread neotropical (including the caribbean and southern florida) a. dissimile was recovered on andros island from three species of reptiles all for the first time: the andros iguana cyclura cychlura cychlura cuvier, the andros curly tail lizard leiocephalus carinatus coryi schmidt, and the andros boa epicrates striatus fow ... | 2005 | 16134982 |
| reptile-associated ticks from dominica and the bahamas with notes on hyperparasitic erythraeid mites. | ticks were collected or recorded from 522 individual reptiles on dominica and from 658 reptiles from the bahamas. two species of ticks were collected on dominica: amblyomma antillorum and amblyomma rotundatum. similarly, 2 species were collected in the bahamas: amblyomma albopictum and amblyomma torrei. on dominica, a. antillorum was recorded from 517 lesser antillean iguanas (iguana delicatissima), 2 boa constrictors (boa nebulosa), 1 antilles snake (alsophis sibonius), and 1 dominican ground l ... | 2015 | 25274575 |
| genetic diversity and structure in the endangered allen cays rock iguana, cyclura cychlura inornata. | the endangered allen cays rock iguana (cyclura cychlura inornata) is endemic to the allen cays, a tiny cluster of islands in the bahamas. naturally occurring populations exist on only two cays (<4 ha each). however, populations of unknown origin were recently discovered on four additional cays. to investigate patterns of genetic variation among these populations, we analyzed nuclear and mitochondrial markers for 268 individuals. analysis of three mitochondrial gene regions (2,328 bp) and data fo ... | 2016 | 26989628 |
| inferred vs realized patterns of gene flow: an analysis of population structure in the andros island rock iguana. | ecological data, the primary source of information on patterns and rates of migration, can be integrated with genetic data to more accurately describe the realized connectivity between geographically isolated demes. in this paper we implement this approach and discuss its implications for managing populations of the endangered andros island rock iguana, cyclura cychlura cychlura. this iguana is endemic to andros, a highly fragmented landmass of large islands and smaller cays. field observations ... | 2014 | 25229344 |
| ocular health assessment, tear production, and intraocular pressure in the andros island iguana (cyclura cychlura cychlura). | the purpose of this study was to assess the ocular health of a wild population of andros island iguanas (cyclura cychlura cychlura) and determine reference values for tear production and intraocular pressure (iop) for this species. fifty-two iguanas, 20 males and 32 females, ranging in size from 11.1- to 51.0-cm snout-to-vent length (svl), were included in the sample set, with measurements obtained from each eye. no abnormalities were found on ophthalmic examination, with the exception of mild, ... | 2013 | 23505711 |
| physiological effects of tourism and associated food provisioning in an endangered iguana. | deliberately feeding wildlife is an increasingly popular tourism-related activity despite a limited understanding of long-term impacts on the species being fed. as a result, tourist behaviours that may have adverse impacts on imperiled species have often been encouraged without the necessary evaluation or oversight. here, we report the responses of northern bahamian rock iguanas (cyclura cychlura) to human-visitation pressure and associated food provisioning. we compared a variety of blood chemi ... | 2013 | 27293616 |
| marine subsidies likely cause gigantism of iguanas in the bahamas. | we utilized natural experiment opportunities presented by differential conditions (presence/absence of seabirds and invasive species) on cays in the bahamas to study whether interisland variations in food resources contributed to gigantism in allen cays rock iguanas (cyclura cychlura inornata). we analyzed the stable carbon (δ13c) and nitrogen (δ15n) isotope values from iguana tissues and resources from each island food web to test the predictions that (1) food webs on islands with seabirds exhi ... | 2019 | 30850885 |
| obtaining plasma to measure baseline corticosterone concentrations in reptiles: how quick is quick enough? | there is growing interest in the use of glucocorticoid (gc) hormones to understand how wild animals respond to environmental challenges. blood is the best medium for obtaining information about recent gc levels; however, obtaining blood requires restraint and can therefore be stressful and affect gc levels. there is a delay in gcs entering blood, and it is assumed that blood obtained within 3 min of first disturbing an animal reflects a baseline level of gcs, based largely on studies of birds an ... | 2020 | 31733208 |
| host sex, size, and hemoparasite infection influence the effects of ectoparasitic burdens on free-ranging iguanas. | investigations focusing on host-ectoparasite interactions in animals have revealed asymptomatic to severe health and fitness consequences suggesting that species mobilize different interspecific response mechanisms. fewer studies, however, have examined intraspecific responses to ectoparasitic burdens. in this study, we analyzed host health and fitness responses to increasing ectoparasite burdens along with the presence/absence of hemoparasites of free-ranging insular rock iguanas (cyclura cychl ... | 2019 | 30847084 |
