Histograms of the ages of the diversification events.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Histograms are shown for (a) all species found in the Mediterranean Sea, (b) exotics only, (c) non-endemic natives, and (d) endemics. Dashed lines indicate the median based on the mean (M) node age estimates as well as based on the lower (L) and upper (U) bounds for each node's 95% credibility interval. Asterisks near the letters indicate significantly different ages than those expected by a random draw of the same number of species from the global chronogram (P<0.05, two-tailed bootstrap test).
