Are alien fish disadvantaged by extremely variable flow regimes in arid-zone rivers?
The proliferation of alien fish in dryland rivers potentially obstructs the maintenance of river health. Modified flow regimes are hypothesised to facilitate invasions by alien fish but in unregulated dryland rivers, large floods provide a recruitment advantage for native over alien species whereas droughts favour alien species. We tested these hypotheses by using data from a 3-year study (20002003) of fish populations in the unmodified rivers of the Lake Eyre Basin (LEB) of Australia. Results...[Show more]
