Visual sensory networks and effective information transfer in animal groups
Social transmission of information is vital for many group-living animals, allowing coordination of motion and effective response to complex environments. Revealing the interaction networks underlying information flow within these groups is a central challenge. Previous work has modeled interactions between individuals based directly on their relative spatial positions: each individual is consi...
متن کاملDeciphering Interactions in Moving Animal Groups
Collective motion phenomena in large groups of social organisms have long fascinated the observer, especially in cases, such as bird flocks or fish schools, where large-scale highly coordinated actions emerge in the absence of obvious leaders. However, the mechanisms involved in this self-organized behavior are still poorly understood, because the individual-level interactions underlying them r...
متن کاملSupporting Information for How perceived threat increases synchronization in collectively moving animal groups
Here we present supplementary information for the article ”How perceived threat increases synchronization in collectively moving animal groups” in the Proceedings of the Royal Society B. 1 Theoretical methods 1.1 Justification for asynchronous updating scheme Asynchronous updates are integral to our model. Consider a synchronous analogue of our model in which all individuals update at the same ...
متن کاملBayesian Inference for Identifying Interaction Rules in Moving Animal Groups
The emergence of similar collective patterns from different self-propelled particle models of animal groups points to a restricted set of "universal" classes for these patterns. While universality is interesting, it is often the fine details of animal interactions that are of biological importance. Universality thus presents a challenge to inferring such interactions from macroscopic group dyna...
متن کاملDistinguishing social from nonsocial navigation in moving animal groups.
Many animals, such as migrating shoals of fish, navigate in groups. Knowing the mechanisms involved in animal navigation is important when it comes to explaining navigation accuracy, dispersal patterns, population and evolutionary dynamics, and consequently, the design of conservation strategies. When navigating toward a common target, animals could interact socially by sharing available inform...
