It is now widely recognized that knowledge on population genetic structure is important to evaluate population viability and persistence or to establish conservation priorities.
The implications of this result depend on whether previous knowledge of population structure is available and whether one is interested in predicting performance within or among breeding populations.
Knowledge of population behaviors should influence the many dimensions of protection, prevention, response, and recovery.
