| helminths and pentastomida of two synanthropic gecko lizards, hemidactylus mabouia and phyllopezus pollicaris, in an urban area in northeastern brazil. | helminths and pentastomids were examined in exotic hemidactylus mabouia and native phyllopezus pollicaris lizards, living synanthropically in an urban area in the municipality of crato, ceará state, northeastern brazil. a total of 194 lizards were collected, being 76 specimens of h. mabouia e 118 specimens of p. pollicaris. six parasite species were found infecting h. mabouia: the cestode oochoristica sp., the nematodes parapharyngodon sceleratus, physaloptera retusa, physalopteroides venancioi, ... | 2014 | 25627607 |
| prevalence and diversity of hepatozoon in native and exotic geckos from brazil. | hepatozoon is a genus of hemogregarines constituting the most widespread and common reptile hemoparasite. although various molecular assessments of these parasites have been conducted in lizards from africa and europe, similar studies are needed for south american lizards. through amplification and sequencing of fragments of the 18s rrna gene, we assess the prevalence of hepatozoon parasites in 230 geckos from south america, including the endemic species hemidactylus agrius, hemidactylus brasili ... | 2015 | 25169765 |
| phylogeny and cryptic diversity in geckos (phyllopezus; phyllodactylidae; gekkota) from south america's open biomes. | the gecko genus phyllopezus occurs across south america's open biomes: cerrado, seasonally dry tropical forests (sdtf, including caatinga), and chaco. we generated a multi-gene dataset and estimated phylogenetic relationships among described phyllopezus taxa and related species. we included exemplars from both described phyllopezus pollicaris subspecies, p. p. pollicaris and p. p.przewalskii. phylogenies from the concatenated data as well as species trees constructed from individual gene trees w ... | 2012 | 22182991 |
| deep diversification and long-term persistence in the south american 'dry diagonal': integrating continent-wide phylogeography and distribution modeling of geckos. | the relative influence of neogene geomorphological events and quaternary climatic changes as causal mechanisms on neotropical diversification remains largely speculative, as most divergence timing inferences are based on a single locus and have limited taxonomic or geographic sampling. to investigate these influences, we use a multilocus (two mitochondrial and 11 nuclear genes) range-wide sampling of phyllopezus pollicaris, a gecko complex widely distributed across the poorly studied south ameri ... | 2012 | 23025595 |
| phylogenetic analysis of hepatozoon spp. (apicomplexa: hepatozoidae) infecting philodryas patagoniensis (serpentes: dipsadidae) in uruguay. | the purpose of this study was to perform a phylogenetic analysis of hepatozoon spp. infecting philodryas patagoniensis in uruguay. twenty-five road-killed specimens of p. patagoniensis from ten departments were obtained. samples of blood and/or heart tissue were taken. polymerase chain reaction (pcr) assay was carried out amplifying a specific target region of the 18s rrna gene of hepatozoon spp. eighteen out of twenty-five samples were positive to hepatozoon spp., which gave an overall prevalen ... | 2020 | 31938888 |
| description of the egg and larva of raillietiella mottae (pentastomida: raillietiellidae). | in the current study, the structural characteristics of the egg and larva of the pentastomid raillietiella mottae (almeida, freire, & lopes 2008), are described and compared with those of other pentastomids. the eggs and larvae were obtained from lizards phyllopezus periosus (rodrigues 1986) and phyllopezus pollicaris (spix 1825) which were collected in the environmental protection area of cachoeira de missão velha, ceará state, northeastern brazil (7° 13' s; 39° 08' w). following collection, th ... | 2020 | 32855614 |
| raillietiella mottae (pentastomida: raillietiellidae) parasitizing four species of gekkota lizards (gekkonidae and phyllodactylidae) in the brazilian caatinga. | we tested the role of sex, size, and mass of the lizards phyllopezus pollicaris, gymnodactylus geckoides, hemidactylus agrius, lygodactylus klugei, and hemidactylus brasilianus on the rates of pentastomid infection in the brazilian caatinga. we collected 355 individuals of these five species, of which four (prevalence of infection: p. pollicaris 15.9 %, g. geckoides 1.4 %, h. agrius 28.57 %, and h. brasilianus 4.16 %) were infected by raillietiella mottae. parasite abundance was influenced by ho ... | 2018 | 31662640 |
