This website presents the full reproducible workflow for our study of how increasing environmental unpredictability affects bloom timing, phenological mismatch, and reproductive success in the Blue-footed Booby.

ImportantCore idea

Climate change may erode reproductive performance not only by shifting the average timing of environmental events, but by making those events less predictable from year to year.
