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).
