Titre de la thèse : Social networks as a trade-off between optimal information transmission and reduced disease transmission.
Période : 2013-2016
Encadrant(s) : Cédric Sueur, Andrew MacIntosh
Social transmission of behavior and disease can take many forms and may deeply affect an individual’s fitness. In theory, the social network properties optimizing the spreading of information should also increase the disease transmission rate, creating a trade-off between information transmission and infection risk. We aim to explore this trade-off by examining social network properties and investigating how they might interact to maximize information flow and minimize infection risk. First, we are interested to investigate the relationship between network properties and the propagation of a theoretical infectious agent in Japanese macaques (Macaca fuscata, Blyth, 1875) and later, to explore how the removal of central and trait-based individuals affect the spread of pathogens in chimpanzees (Pan troglodytes, Blumenbach, 1776) networks (Task 1). In a second phase, we will measure the efficiency of 95 interactions matrices of 26 primates species (wild and captive) and compare them with artificial social networks in order to define specific or general patterns which could be influencing the information and disease transmission rate (Task 2). Finally, we aim to develop a trade-off model that will provide an optimal scenario of information and disease transmission to a vast range of species (Task 3). Our findings will not only provide information concerning the mechanisms of social transmission within a group, but will also show how social network structures and dynamic vary depending on different factors such as group composition and size, providing further information of how primates lead with the benefits and costs of group-living.
