From bacteria to tuna: how invisible microbes make marine life possible
Channel: Planet Tuna
Date: 2020-11-24

Currently, the different species of tuna are considered one of the main sources of animal protein in the world. Despite its economic and ecological importance, the mechanisms that sustain the food chain and many aspects of its biology and ecology, such as, the relationship between bacteria and tunas, are still unknown.

There are many studies that have focused on investigating the distribution and biology of different populations of species. This video links all the species that make up the ecosystem through their trophic relationship, dedicating a special interest in the planktonic community, which is what sustains the rest of the food chain.

The video is based on Catalina Mena's doctoral thesis, entitled Microbial communities across the oligotrophic western Mediterranean Sea: spatial and temporal dynamics and it is possible hanks to the collaboration of the University of the Balearic Islands, through Education for Global Citizenship call.
