vicariance

Innovation between redundancy and vicariance: the rising need for a culture of variety

Innovative processes, by their very definition, relate to phases of instability and transformation, characterized by the circumstances in which traditional schemes and models that belong to the cognitive endowment of the decision maker – and that can be defined as consolidated within its specific context of reference – appear ineffective, ending to be progressively not adequate, when reiterated in the attempt to be used to recover the balance of the organization.

Messinian salinity crisis and Quaternary glacial events shaped genetic diversification in Siculo-Maghrebian blister beetles (Coleoptera: Meloidae)

Three non-phoretic blister-beetle species (Mylabris schreibersi, Actenodia distincta and Cabalia segetum) were investigated to trace their Siculo-Maghrebian biogeographic origins and to understand how Tertiary and Quaternary paleogeographic events (e.g. the ‘Messinian Salinity Crisis’ and the cyclic Quaternary glacio-eustatic marine oscillations) shaped their phylogeographic patterns. Data from CAD and RpP01 nuclear genes highlighted a clear lineage sorting between Sicilian and Maghrebian populations of M.
