Diploid Odontophrynus cordobae and tetraploid Odontophrynus americanus coexist in syntopy in central Argentina, and recently a hybrid zone between them with numerous triploid individuals has been reported. Furthermore, hybrid polyploids with odd numb

Polyploidization plays an important role in speciation and evolution in anurans. However, a few stable triploid populations and some isolated triploid individuals have been reported. Here, we report the discovery of naturally occurring triploids in c

We in situ assessed the influence of natural fluoride concentrations in lotic freshwater ecosystems on diet and morphology of Boana cordobae tadpoles. Two streams were sampled in Argentina: Los Vallecitos stream (LF-LV) and Los Cerros Negros stream (

Evaluation in situ of genotoxic and cytotoxic response in the diploid/polyploid complex Odontophrynus (Anura: Odontophrynidae) inhabiting agroecosystems

Autor: Pablo Raúl Grenat, Manuel Alejandro Otero, Nancy Edith Salas, Adolfo Ludovico Martino, Selene Babini, Favio E. Pollo

Polyploidization has been documented across a wide range of vertebrates. Gene duplication could promote better adaptation to environmental changes and to chronic injury or stress. We investigated if genotoxic and cytotoxic responses to agricultural i

Little attention has been paid to the impact of wastewater generated by mining activities on fluoride. In this study, we evaluated the hematology responses of common South American toad Rhinella arenarum inhabiting natural and artificial environments
