Arctic seasonality is one of the most extreme in the world with the unforgiving cold and seemingly lifeless winters followed by cool summers teaming with life. Even if this extreme cold represent a major challenge for life itself, the wildlife has adapted multiple ways to exploit simultaneously the not-so-obvious advantages of living on the tundra. The short summer seasons drive many of these adaptations and strongly shape Arctic biodiversity. In this session, we will address questions such as: what are the seasonal strategies of each species to survive in this poorly productive landscape? What are the seasonal strategies of migratory animals and those that are more sedentary? How does climate change affect the phenology of migratory and resident species? Could we anticipate a trophic mismatch between resident and migratory species? what are the cascading consequences of the highly asymmetrical food web between winter and summer?
