Collective motion, where large numbers of individuals move synchronously together, is achieved when adopt interaction rules that determine how they respond to their neighbors’ movements and positions. These group-living animals move, make decisions, transmit information between individuals. Nonetheless, few studies have explicitly determined these in moving groups, very little known about the fish. Here, we identify three key for social interactions mosquitofish ( Gambusia holbrooki ): i )...
We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spatial positions in experimental arena different times. Then derived response function individual to looking correlations between changes speed or direction ants. Ants were found turn local concentrations, while their was largely unaffected these concentrations. did not integrate over time, with concentration 1 cm...
Predation is thought to shape the macroscopic properties of animal groups, making moving groups more cohesive and coordinated. Precisely how predation has shaped individuals' fine-scale social interactions in natural populations, however, unknown. Using high-resolution tracking data shoaling fish (Poecilia reticulata) from populations differing pressure, we show adapts interaction rules. Fish originating high environments formed larger, cohesive, but not polarized than low environments. a...
Significance Social insects build some of the most complex nests found in animal kingdom. Here, we use experiments and modeling to decipher mechanisms involved coordination nest building ant Lasius niger : first characterize architecture its growth with 3D imaging techniques; then, test responses individual ants artificial stimuli. A model entirely based on experimental data confirms that level interactions rules are sufficient reproduce dynamics spatial patterns observed for real nests. Our...
Travelling in groups gives animals opportunities to share route information by following cues from each other's movement. The outcome of group navigation will depend on how individuals respond other within a flock, school, swarm or herd. Despite the abundance modelling studies, only recently have researchers developed techniques determine interaction rules among real animals. Here, we use high-resolution GPS (global positioning system) tracking study these interactions pairs pigeons flying...
Collective animal behaviour is the study of how interactions between individuals produce group level patterns, and why these have evolved. This has proved itself uniquely interdisciplinary, involving physicists, mathematicians, engineers as well biologists. Almost all experimental work in this area related directly or indirectly to mathematical models, with regular movement back forth data statistical fitting. In paper, we describe modelling cycle works collective behaviour. We classify...
Schools of fish and flocks birds can move together in synchrony decide on new directions movement a seamless way. This is possible because group members constantly share directional information with their neighbors. Although detecting the directionality other known to be important maintain cohesion, it not clear how many neighbors each individual simultaneously track pay attention to, what spatial distribution these influential is. Here, we address questions shoals Hemigrammus rhodostomus,...
Purpose: In business markets, working with customers and users has become increasingly important to get knowledge about customer needs develop new products. The purpose of this article is twofold: (1) a framework for analyzing involvement in product development market context, (2) apply particular company describe analyze how it practices involvement. Methodology/approach: takes its main theoretical starting point the industrial network approach, but also uses other literature from...
Value co-creation is a core focus area in both B2B marketing and strategy research, necessitating resource utilization within across organizational boundaries. In the Industrial Marketing Purchasing (IMP) group, scholars have focused on interactions among resources as one important way to analyze central questions about business relationships networks. This has produced breadth of investigations concepts that are locally defined utilized. may hamper further theoretical development inhibit...
Inference of interaction rules animals moving in groups usually relies on an analysis large scale system behaviour. Models are tuned through repeated simulation until they match the observed More recent work has used fine motions to validate and fit groups. Here, we use a Bayesian methodology compare variety models collective motion glass prawns (Paratya australiensis). We show that these exhibit stereotypical 'phase transition', whereby increase density leads onset one direction. this data,...
Environmental temperature influences the physiology and behaviour of ectothermic organisms, including ants. However, complex collective exhibited by ant colonies means that it is difficult to predict how effects translate colony-level functioning features, such as form their nests. This study aims determine environmental on nest excavation rate morphology excavated To this end, we characterized digging activity yellow meadow Lasius flavus confined dig in a nearly two-dimensional experimental...
During simple sensorimotor decision making, neurons in the parietal cortex extract evidence from sensory information provided by visual areas until a is reached. Contextual can bias activity during task and change decision-making parameters. One type of contextual availability reward for correct decisions. We tested hypothesis that frontal lobes basal ganglia use to making maximize reward. Human volunteers underwent functional MRI while decisions about motion dots on computer monitor. On...
Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal can have direct influences on fitness individuals, whereas shape structure influence community dynamics facilitating contacts between different individuals species. In this review, we discuss three key areas in study animal networks: topological properties networks, network morphogenesis growth, behaviour...
We understand little about the energetic costs of flight in free‐ranging birds, part because current techniques for estimating energetics wild are limited. Accelerometry is known to estimate energy expenditure through body movement terrestrial animals, once calibrated using a treadmill with chamber respirometry. The equivalent, wind tunnel mask respirometry, particularly difficult instigate, and has not been applied calibrate accelerometry. take first steps exploring novel method calibrating...
We propose a new method for quantitative characterization of spatial network-like patterns with loops, such as surface fracture patterns, leaf vein networks and urban streets. Such are not well characterized by purely topological estimators: also that both look different result from morphogenetic processes can have similar topology. A local geometric cue -the angles formed the branches at junctions- complement information allow to quantify large scale coherence pattern. For grow over time,...
Background: Recent research in animal behaviour has contributed to determine how alignment, turning responses, and changes of speed mediate flocking schooling interactions different species. Here, we address specifically the problem what interaction responses support nearest neighbour configurations terms mutual position distance. Results: We find that rules observed species may be a simple consequence relative positions individuals assume when they move together, noise inherent with...
