aSDMs identified strong associations between calling behaviour and local environmental conditions and showed robust and consistent predictive performance using two alternative models (regression and boundary). Furthermore, these models better captured climatic variation than correlative models as they use observations at higher temporal resolution. Leer más.

Many anuran species remain to be formally named and described in Amazonia, notably in the Guiana Shield, and particularly in megadiverse groups such as Pristimantis. Several species in the Guiana Shield region have been confused with Pristimantis marmoratus and P. ockendeni. Hylodes grandoculis, a taxon previously placed in the synonymy of P. marmoratus, may be available for one of these species.

Aunque dormimos poco, con la víbora otomana como objetivo, nos despertamos con entusiasmo aquella mañana. El mero hecho de visitar el lugar donde se encontraba una de las serpientes más espectaculares de Europa nos hacía mucha ilusión. Antes de buscar las víboras, miramos un apilamiento de escombros que teníamos junto a la tienda de campaña y había 6 lagartos de cristal (Pseudopus apodhttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjdouKEsigif8_deAT3BcTbyJh6yn2dYFZgjuJFOGhYCIIz9S7aXG9Y_uMZvHocp6biR2e-7PcCnmFzXPupEAZJXAL4X1ybSE4KAS0hUGlhirgZSLkggxSSWpqnXOe9585VAOIn-b978XptRZRsFXh5R1Pfb_i8qckrVoRia-Le_mA4BYdCUsm-dXCF7A/w400-h266/7Montivipera%20xanthina.jpgus).

Recent nomenclatural work found that the nomen Salamandra quadramaculata Holbrook, 1840 was unavailable for this species and that no valid nomen had ever been applied at the species level. We erect three new species and resurrect one junior synonym to account for species-level geographic genetic variation in the group.  Leer más
