Percentage of taxa classified by change in timing of larval occurrence and examples of earlier and later shifts in the Northeast U.S. Shelf Ecosystem.

Changes in relative proportion of larvae in bi-monthly seasonal larval collections between 1977–1987 and 1999–2008 were tested using Kruskal-Wallis chi-square. Seasonal changes were classified as no change, earlier, or later and grouped by the larval season of occurrence in the NEUS Shelf (A). Examples of temporal shifts include: Limanda ferruginea (B), which occurred earlier in the season during the 1999–2008 period and Lophius americanus (C), which occurred later in the season. * 0.025 < p ≤ 0.05, ** 0.001 < p ≤ 0.025, *** p ≤ 0.001.
