Our results also point to a lower sensitivity of traditional morphological tools to capture the signal that intensive agriculture leaves on development and a lack of capacity of climatic factors in isolation to predict variation in the degree of asymmetry. In addition to encouraging the use of high‐precision methods, we hypothesize on the overall effect of different stressors linked to intensive agriculture as the real constraint. Leer más.

he differences detected in the venom profiles, as well as in presence/absence and relative abundances of toxin families, indicate the occurrence of intraspecific venom variation within V. monticola. The identified patterns of venom similarity between subspecies seem to align more with their phylogenetic relationships than with the reported differences in their feeding habits. Leer más.

Four species of the genus Panaspis – P. cabindae, P. wahlbergii, P. maculicollis and P. mocamedensis – are currently known from Angola. The analysis of recently collected specimens from Serra da Neve Inselberg, an isolated mountain located in northern Namibe Province, revealed unexpected taxonomic diversity in the group. Leer más.

The interplay between morphological (structures) and behavioral (acts) signals in contest assessment is still poorly understood. During contests, males of the common wall lizard (Podarcis muralis) display both morphological (i.e. static color patches) and behavioral (i.e. raised-body display, foot shakes) traits. We set out to evaluate the role of these putative signals in determining the outcome and intensity of contests by recording agonistic behavior in ten mesocosm enclosures.  Leer más.
