Topic	Sub-topic
Introduction to Marine Ecology	Presentation of the subject. Methodological approximations to the study of marine ecosystems. Scales of the physical processes of interest in Marine Ecology.
Planktonic Ecosystems	Primary production: physical control and variability. Flows of nutrients. New and regenerated production. Secondary production. Food webs, herbivorous and microbial.
Nektonic ecosystems	Global nectonic production. Global data. Life strategies and migrations. Fish abundance and variability. Hydroclimatic processes: effects at the global change. Top-down effects: fishing and changes in community structure.
Soft substrate benthic Ecosystems	Shallow benthic communities on soft substrate. Reactions of oxidation of organic matter. Regression and resilience. Carbon capture. Habitat fragmentation.
Hard substrate benthic ecosystems.	Benthic communities on hard substrate. Factors of control of community structure. Global change and community structure.
Applications of "Omic" technologies in Marine Ecology	From gene to genome in Marine Ecology. Genomics, transcriptomics, proteomics and metabolomics: Sampling and analysis. Application of "omic" technologies in pure cultures: use of model organisms. "Omic" technologies in natural communities. A case of study in marine microbiology: Rhodospsin.
Isotopic ecology	Bases of isotopic ecology. Carbon isotopes: determination of diets, remineralization processes. Nitrogen nitrogen: determination trophic levels, eutrophication. Sulphur Isotopes: sources of matter.
