Supplementary material from Landfast ice: a major driver of reproductive success in a polar seabird

In a fast-changing world, polar ecosystems are threatened by climate variability. Understanding the roles of fine-scale processes, linear and nonlinear effects of climate factors on the demography of polar species are crucial for anticipating the future state of these fragile ecosystems. While the e...
