Fish schooling is a phenomenon of long-lasting interest in ethology and ecology, widely spread across taxa and ecological contexts, and has attracted much interest from statistical physics and theoretical biology as a case of self-organized behaviour. One topic of intense interest is the search of specific behavioural mechanisms at stake at the individual(More)
We determine the basic phase diagram of the fish school model derived from data by Gautrais et al (PLoS Comp. Biol. 8, e1002678 (2012) [1]), exploring its parameter space beyond the parameter values determined experimentally on groups of barred flagtails (Kuhlia mugil) swimming in a shallow tank. A modified model is studied alongside the original one, in(More)
Fish schools are able to display a rich variety of collective states and behavioural responses when they are confronted by threats. However, a school's response to perturbations may be different depending on the nature of its collective state. Here we use a previously developed data-driven fish school model to investigate how the school responds to(More)
BTX (benzene, ethylbenzene, toluene and p-xylene) and meteorological parameters were measured in ambient air of an urban site located in Carmen City, Campeche, Mexico. A total of 412 samples were collected for BTX and analyzed by Gas Chromatography with Flame Ionization Detection (GC-FID). Meteorological parameters were measured by a portable station. A(More)
Tounderstand the collective behaviors of biological swarms,flocks, and colonies, we investigated the non-equilibriumdynamic patterns of self-propelled particle systems using statisticalmechanics methods andH-stability analysis ofHamiltonian systems. By varying the individual vision range, we observed phase transitions between four phases, i.e., gas,(More)
