For leaf area Epilobiumciliatum shows rates of change from Eleaf area(t) 0.001-0.21, with the maximum rate of change observed in 1927 (Figure 2). Seneciosqualidus leaf area rates of change ranges from Eleafarea(t) = 0.07-0.29, with the maximum rate of change in 1907 (Figure 2). For Seneciosqualidus leaf area was the trait with the highest rate of change. Veronica persica’s leaf area rates of change ranges from Eleafarea(t) 0.03-0.27, with the maximum rate of change in 1985 (Figure 2).
In the case of leaf shape Epilobiumciliatum shows rates of change between Eleafshape(t) = 0.01-0.21, with the maximum rate of change observed in 1934 (Figure 2; coinciding with the release of the song “What a diff’rence a day made”). Seneciosqualidus rate of change in leaf shape ranges from Eleaf shape (t) = 0.02-0.22, with the maximum rate of change observed in 1907, as its’ leaf area does (Figure 2). For Veronica persica the rates of change on leaf shape ranged from Eleafshape(t) = 0.04-0.3, with the maximum rate of change observed in 2005 (Figure 2). For Veronica persica leaf shape was the trait that registered the highest rate of change.
For Epilobiumciliatum plant height rate of change varies from E plant height (t) = 0.005-0.31, with the maximum rate of change observed in 1930 (Figure 2). This is the trait that shows the highest rate of change for this species. In the case of Seneciosqualidus the rate of change on plant height ranges from E plant height (t) = 0.04-0.24 (Figure 2). For this trait for this species the maximum rate of change was observed in 1980 (Figure 2). For Veronica persicathe rates of change for plant height ranged from E plant height (t) = 0.07-0.16 (Figure 2). We observed the maximum rate of change on plant height for this species on 1937.
