Biography
Juliana is a biologist with an interest in fisheries and conservation in tropical marine ecosystems. Her research focuses on the interaction between ecological, social, and cultural characteristics of coastal communities, using science to inform best practices and promote sustainable livelihoods. She is a founding director of Talking Oceans (http://talking-oceans.org/) a marine conservation non-profit organization in Colombia. Juliana has a diverse range of experience including work in socio-ecological resilience models, marine protected area effectiveness, parrotfish conservation strategies, elasmobranch critical habitat and ecology, sawfish conservation, and divulgation of science through film festivals. Currently she has focused her research on the role of mangrove nursery grounds in enhancing fisheries yields.

Description of PhD
Title: Mangroves and estuaries protection for fisheries purposes in the Eastern Tropical Pacific

Description of Thesis
Overfishing, pollution and bycatch threaten fisheries health in the Eastern Tropical Pacific (ETP), one of the most productive marine ecosystems of the world and an important migratory route for many marine species. To enhance the ecological resilience of this area, and ensure that it can support sustainable fisheries, there is an urgent need to strengthen existing protection schemes. Current conservation efforts aim predominantly at protecting biodiversity through marine reserves, yet in regional fisheries, success is measured in terms of productivity and recruitment to populations of commercially important species. Effective protection of nursery grounds such as mangroves can ensure a twofold success of protected areas by safeguarding economically important juveniles and habitat, while fostering biodiversity. My research aims to assess the effectiveness of the existent marine protected area network in the ETP in achieving these two complimentary benefits, in order to strengthen the return of healthy fish stocks and support the move towards sustainable regional fisheries. Recommendations from this study will prove especially crucial given system connectivity across international boundaries, as well as provide essential information for fisheries sustainability and marine protected area management.
