[FRB-CESAB] Newsletter 11 CESAB – September 2024

A few words from Denis Couvet, President of the FRB, and Nicolas Mouquet, Scientific Director of CESAB

 

The CESAB – Centre for the Synthesis and Analysis of Biodiversity – is an original, innovative program of the FRB, internationally recognized thanks to the work of an entire team and the support of the founding members of the FRB and the Ministry in charge of research. It provides researchers with a space and time to contribute to addressing the challenges related to biodiversity loss and to implement transformative change. The complexity of these challenges has led the FRB and its board of directors to focus on intermediation, which means connecting knowledge, researchers, and research with stakeholders and society. Innovation is also needed in this area so that knowledge circulates and is embraced by both public and private decision-makers. We can envision the FRB being a driving force in accelerating this flow of knowledge, particularly through the projects funded or hosted by the CESAB, which produce groundbreaking and highly relevant knowledge. This is because the young researchers recruited come from diverse backgrounds and countries, because the project leaders at CESAB are top-level researchers, because the FRB encourages translating these findings into societal issues, and because of its unique position in the research world. Its links with stakeholders make the FRB and its CESAB a laboratory where innovation in science-based messaging is fostered. Next December, two major reports will be published by the IPBES: the first on transformative change, and the second on the Biodiversity Nexus, which includes biodiversity, food, climate, water, and health. It will be interesting to explore how the projects and research results published within the CESAB framework contribute to the intermediation of the key messages from these reports.

We are at a key stage in the trajectory of the CESAB, which is now asserting itself as a major player in biodiversity research. We have reached true maturity, with the stabilization of numerous research groups (over 30 active groups in 2024; 500 researchers involved) producing scientific syntheses of remarkable scope. This positive dynamic also extends to our postdoctoral researchers, several of whom have secured research positions, such as Aurore Receveur from the MAESTRO group, now a research scientist at IRD, Kevin Hoeffner from the LANDWORM group, now a research scientist at INRAE, and Aaron Sexton from the NAVIDIV group, now an assistant professor at Cornell University. Congratulations to them!

At the same time, we launched the CESABinars, a new format of virtual exchanges that has been very successful. These webinars provide a platform where our researchers can share their progress and engage with the international scientific community, further strengthening our network and impact. We are also organizing an international conference in Montpellier in December with the FISHGLOB group, “Fish Biodiversity Facing Global Change.” Finally, we will be welcoming a new data scientist dedicated to the groups formed through the Synthesis call “Human Pressures and Impacts on Terrestrial Biodiversity,” in partnership with MTECT and OFB, where more than 10 groups are creating a true ecosystem within the CESAB. The coming months promise to be just as exciting, with the selection of new groups as part of our 2024 General Call for Synthesis Projects. But it will be in 2025 that we reach a new milestone with the launch of “IdeaShare,” an innovative project call format designed to stimulate creativity and explore new research avenues.

This positive momentum is made possible thanks to the FRB team dedicated to the CESAB, the true driving force of our center. Their expertise, dedication, and passion are at the heart of our success. Thank you to them! We invite you to follow these exciting developments and continue to actively participate in the life of the CESAB.

Nicolas Mouquet, Scientific Director of the CESAB and Research Director at CNRS

[FRB-CESAB] CESABINARs

CESABINARs, which are held in English on Zoom, last approximately one hour: 40 minutes are dedicated to the presentation, followed by 20 minutes of discussion for questions and deeper exploration of the topics covered.

Here, you will find all the information about the upcoming CESABINAR as well as information and recordings of previous sessions.

We look forward to seeing you on Zoom!

 

 

 

NEXT CESABINAR

 

Join us on Friday 7th of March at 2pm (CST) for the seventh Cesabinar! Alienor Jeliazkov (University of Paris-Saclay / INRAE, Antony, France), Aaron Sexton (Technical University of Munich, Germany / Cornell University, USA) and Jean-Nicolas Beisel (Strasbourg University / ENGEES / CNRS, Strasbourg, France) will guide us through the findings of the NAVIDIV group.

 

Exceptionally, this presentation will not be recorded.

Inland navigation infrastructures and biodiversity: impacts and opportunities for waterwayscape management

Facing global change, inland navigation transport is considered as one of the most promising, sustainable transport alternatives to help operate the world ecological transition and achieve climate neutrality. Waterways thus must develop their infrastructures to promote green transport alternatives. However, ecomorphological modifications of rivers will affect biodiversity status and resilience. With the stated objective to sustainable management of waterways, the question therefore remains: what are the impacts of inland navigation on biodiversity, and how to mitigate them? ​

Cues currently available to solve this question rely on scattered case studies whose results are highly context- and scale-dependent. In addition, our knowledge of the processes driving navigation- biodiversity relationships is still limited and requires further research. We thus realised a synthesis project to study the relationships between navigation activity, the associated Inland Navigation Infrastructures (INIs), and biodiversity across different contexts and scales.

Our specific aims are to: ​ (i) Quantify and hierarchize the effects of navigation and INIs on taxonomic and functional biodiversity; (ii) Evaluate the context-dependency and scale-dependency of the INIs-biodiversity ​ relationships; (iii) Assess the potential of restoration plans in mitigating navigation pressures. ​

This work provides impact assessment and synthetic knowledge, offering guidelines on how to prioritize management and restoration actions depending on the context and on which scales to conceive policies that ensure consistency across territories.
