Sea ice and local weather affect reproductive phenology of a polar seabird with breeding consequences
International audience Abstract Breeding at the right time is essential for animals living in seasonal environments to ensure that energy requirements for reproduction, especially the nutritional needs for rearing offspring, coincide with peak food availability. Climate change is likely to cause mod...
