| ecology of the bromeligenous frog phyllodytes luteolus (anura, hylidae) from three restinga remnants across brazil's coast. | in this study, we analyzed diet, sexual dimorphism and bromeliad use in three populations of the hylid frog phyllodytes luteolus from restinga habitats along the brazilian coast. we found 13 arthropods categories in 161 stomachs. ants and termites were the dominant prey items. the similar trophic niche across populations suggests this species has a conservative diet. we found sexual dimorphism regarding body size and jaw width. we recordedp. luteolus in five bromeliad species, but predominantly ... | 2016 | 26871497 |
| effects of insecticides on a phytotelmata-breeding amphibian. | information on the impact of pesticides on amphibian species breeding in phytotelmata (water bodies within plants) is totally lacking. the aim of the present study was to assess the impact of the insecticide malathion on larvae of phyllodytes luteolus. individuals were exposed to ecologically relevant concentrations of malathion (commercial formulation) for 16 d under laboratory conditions. malathion had a lethal effect that allowed the authors to hypothesize that phtytotelmata-breeding species ... | 2017 | 27400022 |
| perspectives on invasive amphibians in brazil. | introduced species have the potential to become invasive and jeopardize entire ecosystems. the success of species establishing viable populations outside their original extent depends primarily on favorable climatic conditions in the invasive ranges. species distribution modeling (sdm) can thus be used to estimate potential habitat suitability for populations of invasive species. here we review the status of six amphibian species with invasive populations in brazil (four domestic species and two ... | 2017 | 28938024 |
| karyotype analysis of seven species of the tribe lophiohylini (hylinae, hylidae, anura), with conventional and molecular cytogenetic techniques. | few species of the tribe lophiohylini have been karyotyped so far, and earlier analyses were performed mainly with standard staining. based on the analysis of seven species with use of routine banding and molecular cytogenetic techniques, the karyotypes were compared and the cytogenetic data were evaluated in the light of the current phylogenies. a karyotype with 2n = 24 and nor in the chromosome 10 detected by ag-impregnation and fish with an rdna probe was shared by aparasphenodon bokermanni m ... | 2012 | 24260681 |
