Figure 3: Distance-based redundancy (dbRDA) plots illustrating distance-based linear modeling (DistLM) of the similarities among stations and their relationships with environmental variables for 18S rRNA [A] and cytochrome oxidase c subunit I (COI) [B] . The axis legends include the percent (%) of variation explained by the fitted model and the % of total variation explained by the axis. Stations are highlighted according to the proposed partitioning of the Gulf of Mexico (N = northern, green triangles; S = southern, blue squares; Y = Yucatan peninsula, blue triangles).
