Data on orientation angle for fall migratory monarch butterflies exposed to experimental magnetic conditions north of, at, and south of their overwintering sites in Mexico. Additional orientation data for butterflies consistently exposed to either fall-like or colder temperatures.
Data set and code for paper "Population extinction and metapopulation synchrony: a reassessment"
The data consists of Z-transformed correlations and ranks in population growth among treatment and experimental populations of the butterfly Parnassius smintheus before during and after experimental extinction.
A second file contains the number of pair-wise dispersal events for these populations during the same period.
R files used to run the analysis are also included.
