  abstract = {{A}im {T}o estimate population extinction rates within freshwater fish communities since the fragmentation of palaeo-rivers due to sea level rise at the end of the {P}leistocene; to combine this information with rates estimated by other approaches (population surveys, fossil records); and to build an empirical extinction-area relationship. {L}ocation {T}emperate rivers from the {N}orthern {H}emisphere, with a special focus on rivers discharging into the {E}nglish {C}hannel, in north-western {F}rance. {M}ethods (1) {F}rench rivers. {W}e used a faunal relaxation approach to estimate extinction rates in coastal rivers after they became isolated by the sea level rise. {T}ributaries within the {S}eine were used to build a species-area relationship for a non-fragmented river system to predict species richness in coastal rivers before their fragmentation. (2) {O}ther rivers. {E}xtinction rates obtained for four other {H}olarctic river systems fragmented at the end of the {P}leistocene, the fragmented populations of one salmonid species ({J}apan) and the fossil records from the {M}ississippi {B}asin were included in the study. {R}esults (1) {F}rench rivers. {W}ithin strictly freshwater fish species, rare and/or habitat specialist species were the most affected by fragmentation. {I}n contrast, euryhaline species were not affected. {A} negative relationship between extinction rate and river basin size was observed. (2) {O}ther rivers. {O}ur study established a common scaling relationship for freshwater fish population extinction rates that spans seven orders of magnitude in river basin size. {M}ain conclusions {T}his study strongly suggests that extinctions of fish populations occurred within {F}rench coastal rivers after they became isolated 8000 years ago. {T}he patterns observed at regional and inter-continental scales are consistent with the expectation that large populations are less prone to extinction than small ones, resulting in a strong extinction-area relationship coherent over a large spatio-temporal scale. {O}ur study is the first multi-scale quantitative assessment of background extinction patterns for freshwater fishes.},
