Temporal trends in numbers of documents reporting costs (left y-axis) and cost entries (right y-axis) concerning invasive alien species within the Mediterranean basin published during 1990–2020. Note the different scales for the two vertical axes. All data shown here reflect costs occurring in 2017 or earlier, as used in our analysis (note that some of these costs were published after 2017).
