Model Problems for Fish Schooling
We review recent work on model systems for body-vortex and body-body interactions in a fluid, related to fish schooling. The studies show a variety of structured and disordered dynamics which can occur when vortices interact with passive and actively-driven deformable bodies. The energy savings due to body-vortex interactions depend strongly on the geometric arrangement of multiple bodies and/o...
متن کاملAssessing learned models of fish schooling behavior
Agent-based simulation is a valuable tool for validating the theoretical models biologists and ethologists use to explain animal behavior. By automating the process of constructing agent-based models (ABM) directly from observation data we can enable researchers to focus more of their time on the analysis of the behaviors and animals in question. We present experimental results using a modified...
متن کاملSchooling properties of an obligate and a facultative fish species
Schooling fish species are conventionally subdivided into obligate and facultative species, depending on the proportion of the time spent in structured schools, but little is known about the factors affecting the group structure in the absence of external structuring stimuli such as food sources, risk of predators or water flow. Changes in attraction and repulsion indicators, depending on the s...
متن کاملInferring the structure and dynamics of interactions in schooling fish.
Determining individual-level interactions that govern highly coordinated motion in animal groups or cellular aggregates has been a long-standing challenge, central to understanding the mechanisms and evolution of collective behavior. Numerous models have been proposed, many of which display realistic-looking dynamics, but nonetheless rely on untested assumptions about how individuals integrate ...
متن کاملCollective States, Multistability and Transitional Behavior in Schooling Fish
The spontaneous emergence of pattern formation is ubiquitous in nature, often arising as a collective phenomenon from interactions among a large number of individual constituents or sub-systems. Understanding, and controlling, collective behavior is dependent on determining the low-level dynamical principles from which spatial and temporal patterns emerge; a key question is whether different gr...
