    <p>Overlap with <i>N. fasciata</i> (a, b) and <i>N. sipedon</i> (c, d). The dotted horizontal line represents the maximum of the sum of sensitivity and specificity threshold; the larger the proportion of the boxplot above this line, the larger the proportion of the native species' range that is projected to be suitable for introduced watersnakes. The thick line in each boxplot represents the median suitability of each native species' range for the watersnake species, and the bottom and top of the box represent the first and third quartiles respectively. The whiskers extend to the most extreme data point that is within 1.5 times the interquartile range from the box.</p

    <p>Suitability from an ensemble model representing the average output from a MaxEnt, Boosted Regression Tree, and Random Forests model.</p

    <p>Connectivity to established populations for (A) <i>Nerodia fasciata</i> and (B) <i>Nerodia sipedon</i>. Classification into suitable and unsuitable areas was done using the maximum of the sum of sensitivity and specificity threshold for ensemble species distribution models.</p

    <p>Overlap with <i>N. fasciata</i> (a, b) and <i>N. sipedon</i> (c, d). The dotted horizontal line represents the maximum of the sum of sensitivity and specificity threshold; the larger the proportion of the boxplot above this line, the larger the proportion of the native species' range that is projected to be suitable for introduced watersnakes. Abbreviations for steelhead populations are as follows: KSβ€Š=β€Š Klamath summer, NCS β€Š=β€Š North Coast summer, CCW β€Š=β€Š Central Coast winter, CVW β€Š=β€Š Central Valley winter, KW β€Š=β€Š Klamath winter, NCW β€Š=β€Š North Coast winter, SCCW β€Š=β€Š South Central Coast winter, SCW β€Š=β€Š South Coast winter. The thick line in each boxplot represents the median suitability of each native species' range for the watersnake species, and the bottom and top of the box represent the first and third quartiles respectively. The whiskers extend to the most extreme data point that is within 1.5 times the interquartile range from the box.</p
