Lévy walkers inside spherical shells with absorbing boundaries: Towards settling the optimal Lévy walk strategy for random searches
L. G. P. Caramês, Y. B. Matos, F. Bartumeus +5
The Lévy flight foraging hypothesis states that organisms must have evolved adaptations to exploit Lévy walk search strategies. Indeed, it is widely accepted that inverse square Lé…
Comment on "Inverse Square Lévy Walks are not Optimal Search Strategies for d 2" [Phys. Rev. Lett. 124, 080601 (2020)]
S. V. Buldyrev, E. P. Raposo, F. Bartumeus +4
It is widely accepted that inverse square Lévy walks are optimal search strategies because they maximize the encounter rate with sparse, randomly distributed, replenishable targets…
A signal of competitive dominance in mid-latitude herbaceous plant communities
Jose A. Capitan, Sara Cuenda, Alejandro Ordoñez +1
Understanding the main determinants of species coexistence across space and time is a central question in ecology. However, ecologists still know little about the scales and condit…
Active and reactive behaviour in human mobility: the influence of attraction points on pedestrians
Mario Gutiérrez-Roig, Oleguer Sagarra, Aitana Oltra +4
Human mobility is becoming an accessible field of study thanks to the progress and availability of tracking technologies as a common feature of smart phones. We describe an example…
First-passage times in multi-scale random walks: the impact of movement scales on search efficiency
Daniel Campos, Frederic Bartumeus, E. P. Raposo +1
An efficient searcher needs to balance properly the tradeoff between the exploration of new spatial areas and the exploitation of nearby resources, an idea which is at the core of…
Expectation-Maximization Binary Clustering for Behavioural Annotation
Joan Garriga, John R. Palmer, Aitana Oltra +1
We present a variant of the well sounded Expectation-Maximization Clustering algorithm that is constrained to generate partitions of the input space into high and low values. The m…
