Recordeu que al llarg de la primavera impartim diverses jornades per combatre la por a les serps. Les serps són uns rèptils sovint temuts i perseguits i és per aquesta raó que creiem que és important tractar la por que algunes persones pateixen. La xerrada serà impartida per una psicòloga professional (Mireia López Riera) amb experiència sobre la por a les serps i personal tècnic de la SCH (Fernando Loras). Inscripcions
Through admixture and phylogenetic analyses of thousands of loci, we provide a comprehensive phylogeographic framework for the A. obstetricans complex, as well as a fully resolved phylogeny for the entire genus. As part of this effort, we carefully explore the influence of different sampling schemes and data filtering thresholds on tree reconstruction, showing that several, slightly different, yet robust topologies may be retrieved with small datasets obtained by stringent SNP calling parameters, especially when admixed individuals are included. In contrast, analyses of incomplete but larger datasets converged on the same phylogeny, irrespective of the reconstruction method used or the proportion of missing data. Leer más.
We found some parasite haplotypes that infected different lizard host genera with ancient diverging histories, which suggested that Karyolysus is less host-specific than other blood parasites of lizards in the region. A co-phylogenetic analysis supported this interpretation because no significant co-speciation signal was shown between Karyolysus and lizard hosts. Leer más.
A new salamander species of the genus Bolitoglossa is here described from the cloud forests of the western slopes of the Cordillera Oriental of Colombia, in the Cundinamarca department. Leer más.
El 2022 inició con la suma de dos nuevas especies de anfibios para la ciencia en Ecuador. En enero, científicos describieron dos ranas ecuatorianas del género Pristimantis en un espacio con gran biodiversidad: el corredor ecológico ubicado en medio de dos de los parques nacionales más importantes de los Andes ecuatorianos, el parque Llanganates y el parque Sangay.
