| on the geographical differentiation of gymnodactylus geckoides spix, 1825 (sauria, gekkonidae): speciation in the brazilian caatingas. | the specific concept of g. geckoides was initially ascertained based on a topotypical sample from salvador, bahia. geographic differentiation was studied through the analysis of two meristic characters (tubercles in a paramedian row and fourth toe lamellae) and color pattern of 327 specimens from 23 localities. it is shown that the population from the southernmost locality, mucugê, is markedly divergent in all characters studied. a holocene refuge model is proposed to explain the pattern. a deci ... | 2004 | 15558150 |
| 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 |
