Due to these shifts in so many ecosystem dynamics, such as flower timing, herbivore interactions, and seasonal breeding, climate change is causing a large shift in the possibilities of population trajectories for migratory bird populations (Johansson & Jonzén, 2012).	cache/concept-1522.pdf	txt/concept-1522.txt
