Signal emission rate across species

Where: LSCP (Dept d'Etudes Cognitives, ENS) Supervisors: Ambre Salis and Emmanuel Chemla [advisors remote, but even more so reachable!] Topic: Animals emit signals at different rates. The call rate of vocal sequences may vary across species, and also within a species, when the rate may be indicative of varying degrees of emergency, proximity, quality of food, certainty of the information, etc. The goal of this internship is to review the literature on the topic to document precisely how call rate is used in the animal kingdom, and to reveal the phylogenetic history of this feature-meaning mapping. Suggested format: mini-internship Learning/Tasks (depending on time): systematic literature review (manual or automated), construction of the database with (species, baseline call rates, observed effect of varying call rates, reference), qualitative and quantitative analysis, reconstruction of the likely evolutionary history, writing up
