Update! Watch the recording of this talk.

This talk is an activity from the FEBS Junior Section, an initiative set up by students and young researchers from some of the FEBS Constituent Societies. Each month members of the FEBS Junior Section organize an online event on either a research or a career topic. This talk was coordinated by the junior section of the French Society of Biochemistry and Molecular Biology (SFBBM).

Speaker: Prof. Chris Bowler, from the Ecology and Evolutionary Biology Section, Institut de Biologie de l'École Normale Supérieure (IBENS) in Paris, France.
Topic: "Exploring the Tara Oceans multiverse".
Date and time: 8 May 2025, 19:00 CEST.

Abstract

The ocean is the largest ecosystem on Earth and yet we know very little about it. This is particularly true for the plankton that drift within, even though they form the base of marine food webs and are key players in Earth’s biogeochemical cycles. Ocean plankton are at least as important for the Earth system as the forests on land, but most of them are invisible to the naked eye and thus are largely uncharacterized. To increase our understanding of this underexplored world, a multidisciplinary consortium, Tara Oceans, was formed around the 36-metre research schooner Tara, which sampled plankton at more than 210 sites and multiple depth layers in all the major oceanic regions during expeditions from 2009–2013 (Karsenti et al. Plos Biol., 2011). This talk will summarize the foundational resources from the project, which collectively represent the largest DNA sequencing effort for the oceans (see Science special issue May 22, 2015 and Cell, Nov 14, 2019), and analyses that illustrate several aspects of the Tara Oceans’ eco-systems biology approach to address microbial contributions to ecological and evolutionary processes. The project provides unique resources for several scientific disciplines that are foundational for mapping ocean biodiversity of a wide range of organisms that are rarely studied together, exploring their interactions, and integrating biology into our physico-chemical understanding of the ocean, as well as for identifying new organisms and genes of biotechnological interest. These resources, and the scientific innovations emerging to understand them, are furthermore critical towards developing baseline ecological context and predictive power needed to track the impact of climate change on the ocean.
