  abstract = {{F}reshwater fish species richness on 132 {W}est {E}uropean and {N}orth {A}merican rivers is analysed using eleven variables related to contemporary ecology (nine) and history (two). {T}his is done in order to examine the relative and joint effects of both historical and ongoing processes on the contemporary richness of these two regional fish faunas. {R}elationships are quantified by simple and stepwise multiple regression procedures. {S}pecies-area curves are presented for the fish faunas within both continents. {W}e show that ecological factors statistically explain most of the variation in freshwater fish species richness for both continents. {E}ffects of historical factors are shown to be statistically significant, but add only a little to the variance already explained by ecological factors. {O}ur analyses further indicate that rivers (which flow directly into the ocean) support fewer species of fish than do similarly sized tributaries. {T}he immigration-extinction hypothesis appears to provide a plausible explanation for this observed pattern. {T}he fact that in our final model, a continental effect is still highly significant, leads us not to exclude the possibility of some other historical influences in generating different overall species richness levels on the two continents.
