From: Barn swallows long-distance migration occurs between significantly temperature-correlated areas
Temporal sensitivity analysis. (A) The number of significant positive partial correlations for barn swallows in cluster N at different temporal shifts (positive meaning delay) of the departure date from Africa (x-axis) and the arrival date in Europe (y-axis). (B) Sensitivity of significant correlations between τA,t and τE,t to temporal shifts of the departure date using actual positions in Africa (red circles) or 999 local randomized positions (gray squares, see Methods). Dotted gray lines indicate the 25–75 percentiles.
