An integrated genetic- demographic model to unravel the origin of genetic structure in European eel (Anguilla anguilla L.)

摘要: The evolutionary enlightened management of species with complex life cycles often requires the development mathematical models integrating demographic and genetic data. structure endangered European eel (Anguilla anguilla L.) has been thoroughly analyzed in several studies past years. However, interpretation key biologic processes that determine observed spatio-temporal very challenging owing to cycle this catadromous species. Here, we present first integrated demographic-genetic model applied explicitly accounts for different levels larval adult mixing during oceanic migrations allows us explore alternative hypotheses on differentiation. Our analyses show (i) low occurring dispersal or migration are sufficient erase entirely any differences among sub-populations; (ii) small-scale temporal differentiation recruitment can arise if spawning stock is subdivided distinct reproductive groups; (iii) geographic component might be overestimated a limited number recruits analyzed. study inspire scientific debate other characterized by long-range migrations.
