Fig 2. Percent frequency of occurrence in number of significant distributional shifts and significant directional shifts for taxon and life stages in the Northeast U.S. Shelf Ecosystem.

Significant differences in annual relative proportions were used to examine three directional shifts of larvae and spring- and fall-collected adults separately; therefore, individual taxon could have shifted in as many as three directions (A). Slopes that were significantly different than zero indicated a significant change in distribution in one of the directions: along-shelf, cross-shelf, or depth (B).
