TLDR
A procedure for quantifying movement sequences in terms of move length and turning angle probability distributions is developed and it is shown this displacement formula can be used to highlight the consequences of different searching behaviors.Citations

The Problem of Pattern and Scale in Ecology: The Robert H. MacArthur Award Lecture
TL;DR: The second volume in a series on terrestrial and marine comparisons focusing on the temporal complement of the earlier spatial analysis of patchiness and pattern was published by Levin et al..

TL;DR: This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments, and highlights the experimental relevance of various semimicroscopic derivations of the continuum theory for describing bacterial swarms and suspensions, the cytoskeleton of living cells, and vibrated granular material.
Journal ArticleDOI
Causes and consequences of animal dispersal strategies: relating individual behaviour to spatial dynamics.
Diana E. Bowler,Tim G. Benton +1 more
TL;DR: Logistical difficulties preclude a detailed study of dispersal for many species, however incorporating unrealistic dispersal assumptions in spatial population models may yield inaccurate and costly predictions, and further studies are necessary to explore the importance of incorporating specific condition‐dependent dispersal strategies for evolutionary and population dynamic predictions.
Journal ArticleDOI
Random walk models in biology.
TL;DR: The mathematical theory behind the simple random walk is introduced and how this relates to Brownian motion and diffusive processes in general and a reinforced random walk can be used to model movement where the individual changes its environment.
Book
Spatial Analysis A Guide for Ecologists
TL;DR: In this paper, the authors present a spatial analysis of complete point location data, including points, lines, and graphs, and a multiscale analysis of the data set, including spatial diversity analysis and spatial autocorrelation.

Random dispersal in theoretical populations.
TL;DR: In this paper, the authors used the random walk problem as a starting point for the analytical study of dispersal in living organisms and applied the law of diffusion to the understanding of the spatial distribution of population density in both linear and two-dimensional habitats.

Random dispersal in theoretical populations
TL;DR: The random-walk problem is adopted as a starting point for the analytical study of dispersal in living organisms and the law of diffusion is deduced and applied to the understanding of the spatial distribution of population density in both linear and two-dimensional habitats.

The search for resources by cabbage butterflies (pieris rapae): ecological consequences and adaptive significance of markovian movements in a patchy environment'
Richard B. Root,Peter Kareiva +1 more
TL;DR: A simulation of the flight behavior of ovipositing P. rapae results in the placement of more eggs on isolated hosts to demonstrate the effectiveness of egg spreading in averaging out observed variations in larval survivorship and to estimate the potential advantages accrued by egg spreading.
Journal ArticleDOI
The Food Searching Behaviour of Two European Thrushes. Ii: the Adaptiveness of the Search Patterns
TL;DR: Although there were suggestions of differing capture rates, unforeseen errors in experimental procedure did not allow firm conclusions on the effects of thrush predation on the different prey distributions within each density, it is suggested that the increases in move lengths were an adaptive reaction by the blackbirds to increases in prey detectability.
Journal ArticleDOI
Movement patterns and egg distribution in cabbage butterflies
TL;DR: Butterfly density tends to vary inversely with host density, despite aggregative behaviour identical to that which, in predator-prey systems, leads to a direct correlation between the densities of searcher and resource.
