Fig. 2: Current and potential exposure to 94 invasive species regulated in Europe.
From: Risks posed by invasive species to the provision of ecosystem services in Europe
A Current exposure is measured based on the real number of invasive species currently present using occurrences. B Potential exposure is based on species distribution model predictions of invasive species establishment. C Barplot showing the average area (+SD) under current and potential exposure to invasive species of concern in Europe, respectively. Please note that, to facilitate visualization, the area has been log-transformed. Differences between Current and Potential are highly significant according to a paired Student’s t test (t = −7.14, df = 93, P < 0.001).
