Searching for mechanisms of synchrony in spatially structured gamebird populations
1. Time series data on five species of gamebird from the Dolomitic Alps were used to examine the relative importance of dispersal and common stochastic events in causing synchrony between spatially structured populations. 2. Cross‐correlation analysis of detrended time series was used to describe th...
