  • spatial synchrony of insect outbreaks;
  • “spatial synchrony,” spatially disjunct populations correlated in time;
  • quantifying synchrony, using Pearson product–moment correlation;
  • ubiquity of spatial synchrony in forest outbreaks, and “inverse problem”;
  • trophic interactions;
  • food web interactions in population synchrony;
  • spatial synchrony in population dynamics, weather varying with time;
  • outbreak synchrony, insect populations and management


This chapter contains sections titled:

  • Introduction

  • Quantifying synchrony

  • Causes of spatial synchrony

  • The ubiquity of synchrony and its implications
