Cuando los anfibios fueron expuestos a altas concentraciones de litio, en cantidades similares a las que se encuentran en humedales y fuentes de agua dulce cercanas a zonas mineras, presentaron una mortalidad significativa tras solo una semana de exposición. Leer más.
Ecological groups differ in patterns of disparity, convergence and rates of evolution, indicating that divergent evolutionary mechanisms are responsible for the acquisition of different diets and habitats. Our analyses support that lepidosaurs ancestrally use their jaws to capture prey, contrary to the traditional view favouring lingual prehension as ancestral. Leer más.
This study highlights the importance of continuous monitoring and research to unravel the dynamics and complexity of water frog population systems. Leer más.
When chronic exposure to ammonium and artificial heating were applied to tadpoles, tadpoles in heated water were larger, metamorphosed earlier, and as smaller metamorphs. Heated water produced faster larvae but metamorphs reared in nonheated water jumped farther. Ammonium caused increased mortality. Leer más.
