Jose Marín Jarrín, PhD.

I am interested in the ecology fish and crustaceans, the dynamics of coastal populations and communities, life history diversity and its influence on population resilience, habitat use and selection, and the potential impact of climate change on fish populations. I use a combination of field and laboratory analysis such as multiple modeling and statistical techniques, and otolith, genetic, diet, bioenergetics and individual coupled, physical-biological modeling analysis techniques.
