The species, described recently in Amphibian & Reptile Conservation by Fernando Ayala-Varela and colleagues, comes from the western slope of the Andes in Ecuador. In appearance, it’s most similar to A. gemmosus, which occurs to the north. Detailed examination shows it to be most phenotypically similar to that species and A. otongae, and DNA analysis indicates that A. gemmosus is its sister taxon. Leer más.
A new Baurusuchidae (Crocodyliformes, Mesoeucrocodylia), Aplestosuchus sordidus, is described based on a nearly complete skeleton collected in deposits of the Adamantina Formation (Bauru Group, Late Cretaceous) of Brazil. Leer más.
|Three basic conclusions can be drawn with respect to the linkage of individual movement behaviour and spatial or genetic structure of local amphibian populations embedded in a heterogeneous landscape: (1) individual movements or consecutive short-term series of movements are misleading surrogate measures of total movement capacity; (2) probabilistic modelling of movement capacity is the best available behavioural predictor of interpatch gene flow; (3) connectivity of local populations in heterogeneous landscapes is less affected by landscape resistance than previously expected.
