SOUNDSCAPES : A TOOL TO HEAR AND POINT OUT SOCIO-ENVIRONMENTAL CHANGES AND TO FEED LOCAL MOBILIZATION PROJECTS?
Anne Sourdril and Luc Barbaro presented their project Soundscapes at the Blois conference Unheard Soundscapes that took place in Blois, France from October 27-30, 2021.
The project Sonatas (Listening tothe SOunds of NAture to undersTAnd global environmental changeS), a project financed by iGLOBES - LabEx Driihm, seeks to understand how two mining communities in Arizona hear, react and adapt to changes in their territories. Anne, Luc and their team are documenting the impact of mining operations on ecosystems and biodiversity with interviews of local communities and acoustic recordings of soundscapes near the sites.
Mining territories are places of citizen mobilization : inhabitants organize thmselves to stop or minimize the impact of mining, creating more or less institutionalized collectives and promoting protective measures to stop its progression. Through Sonatas, the researchers wish to show how soundscapes can be a tool for local action.

2 ENS DOCTORAL STUDENTS TO PRESENT THEIR RESEARCH AT THE AGU FALL MEETING 2021
Philippe Cherabier and Antonin Affholder, doctoral students at the Ecole Normale Supérieure in Paris will present their research at AGU - Advancing Earth and Space Science, with financial backing from iGLOBES. One of Philippe's presentations will be on Integrating eco-evolutionary dynamics in general circulation models.
General circulation models are a class of models that allow us to simulate the evolution of atmospheric and oceanic circulation under multiple constraints. When coupled to biological models of the oceans, they can be used to predict future carbon fluxes in the Anthropocene, and as such are a cornerstone of the IPCC reports. However, a potentially important component is missing from these models, namely the adaptation through selection of key populations. Bacterial populations in particular can evolve rapidly and exert important variations in carbon fluxes, showing the necessity to take eco-evolutionary processes into account for a precise prediction of the effects of climate change. During the AGU Fall Meeting 2021, I will be presenting a novel method for integrating these processes in general circulation models based on the selection gradient: dx
---- = α ⋅ N ⋅ ∂_1 S(x,x)
dt
where x represents the trait, α an evolutionary speed parameter, N the size of the population and ∂_1 S(x,x) the selection gradient. This method presents multiple perks: it is designed to fit current global circulation models, has a low numerical cost and allows for a biological interpretation at any time step or grid point. It was tested on the NEMO-PISCES coupled model to predict the evolution of bacterial growth efficiency.

1. CALL FOR RESEARCH PROJECTS 2022 LABEX DRIIHM
Deadline: December 5, 2021
The OHMI 2022 call is now open! See here for more information and specific modalities and topic for the Pima County Human-Environment Observatory. Please note than in addition to the PIma County call there is an "inter-OHM" call for projects that will be developed involving at least two different sites. We hope to have as many proposals as possible!
2. STUDY AT A PRESTIGIOUS SCHOOL IN PARIS, FRANCE
Deadline: December 9 (Arts & Humanities) and December 12 (Sciences)
The Ecole Normale Supérieure (ENS) of Paris holds a prestigious place within the best universities worldwide. Students are granted stimulating surroundings and a diversified offer for many formations. International Selection is a great opportunity for students to join a French university of excellence. They can prepare for a Master and ENS graduate degree. With both a personal tutor and a grant, they will be offered the best possible conditions to study. For more information...
