Geometrical Structure of Bifurcations during Spatial Decision-Making Open
Animals must constantly make decisions on the move, such as when choosing among multiple options, or “targets,” in space. Recent evidence suggests that this results from a recursive feedback between the (vectorial) neural representation of…

Models of Animal Behavior as Active Particle Systems with Nonreciprocal Interactions Open
Active particle systems of interacting self-propelled particles offer a versatile framework for modeling complex systems. When employed to describe aspects of animal behavior, the complexity of animal movement and decision-making often req…

An effective hydrodynamic description of marching locusts Open
A fundamental question in complex systems is how to relate interactions between individual components (‘microscopic description’) to the global properties of the system (‘macroscopic description’). Furthermore, it is unclear whether such a…

A simple cognitive model explains movement decisions in zebrafish while following leaders Open
While moving, animals must frequently make decisions about their future travel direction, whether they are alone or in a group. Here we investigate this process for zebrafish ( Danio rerio ), which naturally move in cohesive groups. Employ…

The geometry of decision-making in individuals and collectives Open
Significance Almost all animals must make decisions on the move. Here, employing an approach that integrates theory and high-throughput experiments (using state-of-the-art virtual reality), we reveal that there exist fundamental geometrica…

Spatiotemporal dynamics of animal contests arise from effective forces between contestants Open
Significance To obtain and defend resources, animals often participate in contests that involve complex trade-offs between risk and reward. Although it stands to reason to invoke cognitive decision-making schemes to analyze and model these…

The geometry of decision-making Open
Choosing among spatially-distributed options is a central challenge for animals, from deciding among alternative potential food sources or refuges, to choosing with whom to associate. Using an integrated theoretical and experimental approa…

Dynamics on the web: spiders use physical rules to solve complex tasks in mate search and competition Open
A long-standing question in animal behaviour is how organisms solve complex tasks. Here we explore how the dynamics of animal behaviour in the ubiquitous tasks of mate-search and competition can arise from a physics-based model of effectiv…

Pair formation in insect swarms driven by adaptive long-range interactions Open
In swarms of flying insects, the motions of individuals are largely uncoordinated with those of their neighbours, unlike the highly ordered motion of bird flocks. However, it has been observed that insects may transiently form pairs with s…

Stable swarming using adaptive long-range interactions Open
Sensory mechanisms in biology, from cells to humans, have the property of adaptivity, whereby the response produced by the sensor is adapted to the overall amplitude of the signal, reducing the sensitivity in the presence of strong stimulu…

Long-range Acoustic Interactions in Insect Swarms: An Adaptive Gravity Model Open
The collective motion of groups of animals emerges from the net effect of the interactions between individual members of the group. In many cases, such as birds, fish, or ungulates, these interactions are mediated by sensory stimuli that p…
