Animals publishes a ReXenMar study on the EST-Microsatellite Types and Structural Scenarios in European Hake Fisheries

The work was part of María Fernández Míguez‘s doctoral thesis

The scientific journal Animals, belonging to the MDPI group, collects the results of a study led by research staff from the Marine Genetic Resources Group (ReXenMar) of the Marine Research Center (CIM) of the University of Vigo, which the importance of integrating genetic variation in order to infer meaningful units for management and sustainability.

The article, entitled «EST-Microsatellite Types and Structural Scenarios in European Hake Fisheries» is the result of the joint work of Dr. Pablo Presa, Dr. Alfonso Pita and Dr. María Fernández Míguez. In this study the authors claimed «The conservation of the maximum genetic background from all genomic regions matters for sustainability in the changing global scenario. This study focused the importance of integrating such genetic variation in order to infer meaningful units for management and sustainability. We show that knowledge that can be obtained from different marker types should be goal-oriented, i.e., remnant patterns of selection pressures and extreme drift episodes (directional markers, i.e., the evolutionary genetic background), current evolutionary novelty and adaptive potential for fisheries’ sustainability (balanced markers, i.e., the potential genetic drive of the species), and demographic dynamics of genetic relevance for fisheries’ management (neutral markers, i.e., the present-day fishery structure and connectivity). In particular, special attention should be paid to the variation in supergenes or balancing markers, which are a rich source of evolutionary novelty and can be crucial for species welfare and survival.»
