Null model 1 yielded the highest SES values of disappearances
(SESdisp) in the Northern part of the study area (i.e. Luxembourg
and several neighboring administrative units from North Western
to North Eastern France and in Belgium, Fig. 1A). The administrative
unit ‘Walloon Brabant’ (Belgium) showed significantly more
disappearances than in the null model (P < 0.05, Fig. 1A).
