Bird migration in the Eastern Hemisphere
Copyright National Geographic Society.
Movement of an organism, defined as a change in the spatial location of the whole individual in time, is a fundamental characteristic of life, driven by processes that act across multiple spatial and temporal scales. It plays a major role in determining the fate of individuals; the structure and dynamics of populations, communities, and eco-systems; and the evolution and diversity of life.
Coupling both movement and environmental big data could help determine impacts of major environmental and climate changes on animal - environment interactions, ultimately informing biodiversity conservation and ecosystem management.

Key question: Is the current spatial configuration of conservation areas able to cope with changing habitat conditions to sustain migratory flows?
How to: Linking climate data and spatial attributes within a graph-theoretic modeling framework.
Take home message: Future conservation approaches should take in account the role of conservation areas in maintaining the functional connectivity of migrants be- tween different periods of the annual cycle.

Key question: How phenological adjustments relate to the rewiring of potential associations in co-migrating species?
How to: By using temporal co-occurrence networks we can determine whether and how species follow a consistent order of association over time.
Take home message: Birds tend to aggregate in semi-independent groups of species characterized by common responses to changes in migration timing, showing strong co-migration fidelity over the years.
