SpringerLinkConsumer coexistence through the gleaner–opportunist trade-off in the light of sigmoidal functional responses - Theoretical EcologySpecies coexistence relies on ecological trade-offs, such as the gleaner–opportunist trade-off, which enables two consumers to coexist on a single shared resource through temporal resource variation and differences in their resource-dependent growth rates. The shapes of the consumers’ functional responses play a central role in this mechanism as they determine the consumers’ effect on the stability of the consumer–resource dynamics and their response to resource variation. While recent studies suggest that sigmoidal functional responses may be more common in nature than previously assumed, their impact on coexistence in the gleaner–opportunist model has not been systematically analyzed. In this study, we compared population growth models of two consumers with one or both exhibiting a sigmoidal functional response to the original gleaner–opportunist model with one consumer exhibiting a linear and the other a saturating functional response. Comparing the size of the parameter space allowing coexistence, we found that coexistence is most likely when consumers exhibit contrasting effects on and responses to resource variation, such as one consumer exhibiting a stabilizing sigmoidal and the other a saturating functional response, or one exhibiting a destabilizing sigmoidal and the other a linear functional response. Through this stabilizer–destabilizer trade-off, coexistence can also arise between two consumers that exhibit sigmoidal functional responses. Overall, sigmoidal functional responses provided the opportunity for coexistence that was of similar magnitude as in the original gleaner–opportunist model. Critically, sigmoidal functional responses allowed coexistence for less extreme handling times than the original model, emphasizing their importance when fitting models to empirical data.

Première semaine de contrat, mais déjà de nombreux projets au programme !
Cette semaine, je participe à deux séminaires pour présenter mes travaux.
Aujourd'hui, je serai au séminaire organisé par les jeunes chercheurs de mon laboratoire, qui portera sur l’incertitude. Lors de ce colloque, je reviendrai sur un élément de ma thèse : les séismes ayant frappé Strasbourg en 2019 et 2020. Il sera bien sûr question d’incertitude, mais surtout de la manière dont ces séismes ont permis une prise de conscience du sous-sol auprès des habitants et des élus locaux. Ces derniers cherchent désormais à reprendre le contrôle de cette question, notamment à travers la mise en place de mécanismes de gouvernance territorialisée.
Demain, direction la région parisienne ! Sur l’invitation de deux chercheurs du LATTS, je montrerai comment le sous-sol peut contribuer à la transition énergétique. Je prendrai l’exemple de deux filières, la géothermie et le lithium, pour illustrer comment une politique publique se traduit par le développement de projets concrets. Je montrerai également comment ces projets « atterrissent » sur les territoires pour y être débattus, soulevant ainsi des questions sur les enjeux démocratiques de la transition et des choix opérés. #PhdChat #ESR

“But that’s the way talks have always been done!” – academia has a huge status quo bias, change is slow.

Embrace your rebellious side and go do your talks differently! Audiences get bored, so novelty is a big asset. And by doing it YOUR WAY, it’ll be more honest, authentic, and genuine.

They can direct the audience’s attention to the right place, add emphasis to what you say, & provide variety to keep the audience engaged.

They can also indicate: big things, small things, precise things, vague things, contrasting things, & connected things.
