The results of a review of the chelonian remains retrieved in the excavations carried out in Mealhada (Coimbra, central Portugal) are presented here. Mealhada is a Portuguese Middle Palaeolithic classical site, discovered at the end of the 19th century, and chronologically ascribed to the interglacial Riss-Würm (ca. 120 ka BP). This study has allowed the identification, justification, and figuration of remains attributed to three Iberian chelonian taxa, Testudinidae indet., Mauremys leprosa, and Emys orbicularis, the last one being recognized for the first time in this site.  Leer más.

The book treats biological concepts related to the evolution, ecology, physiology, immunology, behaviour, and morphology of amphibians in their different states. This book constitutes an actualized work indispensable for evolutionary ecologists and herpetologists. Ir al enlace. Previsualización.

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.
