FIGURE 1: Geographic map showing the sampling sites of the
Batillaria attramentaria snails used in the present study. Gray color
represents continental area and white color represent oceanic areas.
Black dots indicate sampling sites of the
snails.
FIGURE 2: Generic Exposure Salinity-response functions of the movement
distance of the B. attramentaria under the effects of (A) Origin,
(B) Location, (C) Population, and (D) Lineage. Gradient blue color boxes
represent the movement distance of the snails exposed to different
salinities. The black and dash curves represent the statistically
significant and insignificant difference between two means. The bottom
and top of the box are the 25th, and
75th percentile of the movement distance, the dash
lines in the box show the 50th percentile, and the
ends of the whiskers represent the minimum and maximum estimates of the
movement distance. Outliers are represented by black dots beyond the
whiskers. Lower panel illustrates definition of ecological factors of
(E) Origin, (F) Location, and (G) Lineage. Blue and red colors in E
represent for native and introduced groups of snails. Curly arrows in F
indicate daily salinity fluctuation from 0 to 33 PSU throughout the
year. The phylogenetic tree in G was built based on mitochondrialCO1 gene sequences (286bp) applying the Maximum Likelihood method
and HKY85+G+I substitution model. Vertical black and white bars
represent for the two distinct lineages of Tsushima and Kuroshio,
respectively.
FIGURE 3: Generic (A) Exposure Salinity, (B)
Origin, (C) Location, (D) Population, (E) Lineage-response function of
the movement distance of the B. attramentaria. The predicted
variables-response derived from the LMM tests, specifying random
intercept for subject, with N = 280 individuals split into groups of
snails acclimating to different salinities of 13, 23, 33, and 43 PSU
(A), from native and introduced ranges (B), coming from different
locations (C) and population (D), and having different genetic
composition (E). The bottom and top of the box are the
25th, and 75th percentile of the
movement distance, the straight dash lines show the
50th percentile, and the ends of the whiskers
represent the minimum and maximum estimates of the movement distance.Outliers are represented by black dots beyond the whiskers. The
solid and dashed black curves represent the statistically significant
and insignificant difference between two means,
respectively.
FIGURE 4: Generic (A) Kuroshio
lineage–response function of the movement distance of B. attramentaria
and (B) Salinity Exposure–response functions of the movement distance
of the Kuroshio B. attramentaria under the effects of Origin. Gradient
blue colored boxes represent the movement distance of snails exposed to
different salinities. The solid and dashed black curves represent
statistically significant and insignificant differences between means,
respectively. The bottom and top of the boxes are the
25th, and 75th percentiles, the
dashed vertical lines show the 50th percentiles, and
the ends of the whiskers represent the minimum and maximum estimates of
the movement distance. Outliers are represented by black dots
beyond the
whiskers.
