ADDRESSING PATTERNS OF VENOM VARIATION IN WESTERN MEDITERRANEAN VIPERS

Snake venoms are complex secretions of bioactive molecules able to disrupt the physiological equilibrium of the organism in which they are injected, known to be used for both predatory and defensive purposes. Several studies have found evidence of adaptation in the composition of snake venoms to diet, reinforcing their role as targets for natural selection, and explaining their geographic variation with different prey preferences. However, other factors (e.g. phylogenetic relationships) might be relevant in shaping the composition of snake venoms, determining the presence of similarities or differences in quantity and/or type of venom components. Vipers (Family Viperidae) are one of the most diverse groups of venomous snakes worldwide, infamous for the generally high potency of their venoms. Leer más.
