Understanding movements of organisms: it's time to abandon the Lévy foraging hypothesis

GH Pyke - Methods in Ecology and Evolution, 2015 - Wiley Online Library
Interest in L évy walks within the context of movement of organisms has recently soared, with
some now referring to this approach as the L évy walk/flight paradigm. The principal …

Assessing Lévy walks as models of animal foraging

A James, MJ Plank… - Journal of the Royal …, 2011 - royalsocietypublishing.org
The hypothesis that the optimal search strategy is a Lévy walk (LW) or Lévy flight, originally
suggested in 1995, has generated an explosion of interest and controversy. Long-standing …

Modelling the scaling properties of human mobility

C Song, T Koren, P Wang, AL Barabási - Nature physics, 2010 - nature.com
Individual human trajectories are characterized by fat-tailed distributions of jump sizes and
waiting times, suggesting the relevance of continuous-time random-walk (CTRW) models for …

Optimal diffusive search: nonequilibrium resetting versus equilibrium dynamics

MR Evans, SN Majumdar, K Mallick - Journal of Physics A …, 2013 - iopscience.iop.org
We study first-passage time problems for a diffusive particle with stochastic resetting with a
finite rate r. The optimal search time is compared quantitatively with that of an effective …

Air pollutants degrade floral scents and increase insect foraging times

JD Fuentes, M Chamecki, T Roulston, B Chen… - Atmospheric …, 2016 - Elsevier
Flowers emit mixtures of scents that mediate plant-insect interactions such as attracting
insect pollinators. Because of their volatile nature, however, floral scents readily react with …

Multi-scale spatio-temporal analysis of human mobility

L Alessandretti, P Sapiezynski, S Lehmann… - PloS one, 2017 - journals.plos.org
The recent availability of digital traces generated by phone calls and online logins has
significantly increased the scientific understanding of human mobility. Until now, however …

Survival in patchy landscapes: the interplay between dispersal, habitat loss and fragmentation

BBS Niebuhr, ME Wosniack, MC Santos, EP Raposo… - Scientific reports, 2015 - nature.com
Habitat loss and fragmentation are important factors determining animal population
dynamics and spatial distribution. Such landscape changes can lead to the deleterious …

Long-range navigation on complex networks using Lévy random walks

AP Riascos, JL Mateos - Physical Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
We introduce a strategy of navigation in undirected networks, including regular, random, and
complex networks, that is inspired by Lévy random walks, generalizing previous navigation …

On the random search for a randomly moving particle

MAA El-Hadidy - Journal of Taibah University for Science, 2022 - Taylor & Francis
This paper discusses some methods based on the random search problem over the bound
domain. The particle moves randomly with a bounded two-dimensional stochastic process in …
