Fig 4. Change in distribution of larval Gadus morhua (Atlantic Cod) in the Northeast U.S. Shelf Ecosystem.

Fig 4

Locations of strata with significant differences in annual relative proportions of larval Gadus morhua between 1977–1987 and 1999–2008 in January—February (A), March—April (B), and May—June (C), were used to examine directional shifts. Linear regressions of the Kruskal-Wallis chi-square (Chi H) for each stratum were tested for each direction: along-shelf (C), cross-shelf (D), and depth (E) to determine if slopes were significantly different than zero, and classify the significant directional shifts. Larval Gadus morhua shifted significantly northward and deeper.
