The frequency of study of different components of the movement ecology framework. (Upper) Compared with the framework, published studies frequently omit feedbacks from movement path to internal state or external factors and links between internal and external factors. Arrow thickness represents the percent of focal studies in which each link was studied. Letters next to arrows label links and give percentages of cases. (Lower) The bar chart breaks the frequency of study into different taxa. *, the three taxa differed at P < 0.05; **, P < 0.005 in G tests. An overall G test for all links simultaneously (thereby protecting alpha) is given.
