    We describe adult specimens and tadpoles of a new species of Telmatobius Wiegmann, 1834, Telmatobius mantaro, from the central Cordillera of the Andes in Peru. Specimens were collected in humid lower montane forests and dry lower montane forests between 2240–3170 m elevation at the northern parts of the Departments of Huancavelica and Ayacucho. We also report a range extension of 262 km west of the type locality for Telmatobius mendelsoni De la Riva et al., 2012, which was found in sympatry with T. mantaro in Ayacucho. The new species has a snout–vent length of 48.9–55.8 mm in three adult males, and both sexes have tympanic membrane differentiated and tympanic annulus visible, a feature that distinguishes the new species from the majority of other Peruvian Telmatobius. We propose to assign the IUCN category Critically Endangered to this species because of its small area of distribution and its high likelihood of being infected by Batrachochytrium dendrobatidis.

    The effect of carboxymethylation and NH4I incorporation on the molecular dynamics of carrageenan films was studied. Broadband Dielectric Spectroscopy (BDS) assessed the presence of α and β relaxation processes. The effect of NH4I content was analyzed using the Havriliak-Negami model and parameterizing the temperature dependence of the relaxation times according to the Vogel-Fulcher-Tammann-Hesse (VFTH) equation. The glass transition temperature was found to decrease with the increase of NH4I content. These results suggest that carboxymethylation and the salt doping treatment increase the molecular mobility of NH4+ ions, making the films suitable for the development of solid electrolytes for energy storage applications. © 2018, © 2018 Taylor & Francis Group, LLC.
