Descripción y contextualización de la asignatura
Genomic research is a powerful tool to provide new knowledge on the demographic and adaptation of marine resources, to support for conservation management and ecosystem health protection.
Seventy-one percent of the earth’s surface is covered by ocean which contains almost 80% of the world’s phyla. In times of overfishing and climate change, marine resources are extremely vulnerable.
The marine environment is dominated by microorganisms from the three domains of life, namely Archaea, Bacteria and Eukarya, being responsible for up to 98% of marine primary productivity and playing key roles in marine food webs as well as in carbon and energy cycles. The unprecedented microbial diversity found on marine realm represents a challenge for the understanding of and exploitation of the biology and biochemistry of the ocean environment. Furthermore, the vast majority of the world’s fish stocks have already collapsed. In this fragile context, the need to drive fisheries towards sustainability has become a priority.
AIM
The course aims to initiate students into population genomic and metagenomic research in the marine world by exploring current research cases, understanding of cutting-edge lab technologies, building bioinformatics/biostatistic skills.

Convocatoria ordinaria: orientaciones y renuncia
• ATTENDANCE IS COMPULSORY. If students have to miss a class it is mandatory to get in contact with the teacher previously.• Proactive participation in the activities, practical and oral sessions, will be evaluated
• MARINE POPULATION GENOMICS topic will be evaluated through a test after the formal lecture and an individual report should be conducted following completion of the computer practices (50% of the total grade)
• METAGENOMICS topic will be evaluated through a report following completion of the computer practices (50% of the total grade).
(The report has to be written in scientific format, and should explain what you did in your computer practices, what you learned, and what the results meant. Thus, argument, research problem statement, methodology and presentation and expression will be evaluated.
Convocatoria extraordinaria: orientaciones y renuncia
