Estimates (and 95% credible intervals; some intervals are smaller than the symbols) are shown for four decades for the common toad (Bufo bufo) and the common frog (Rana temporaria) in Switzerland (left panel) and for three decades for the common toad (Bufo bufo) in five regions of the United Kingdom (right panel).
