Résumé

Synopsis: The tolerance of fantail, rainbow, and greenside darters to low oxygen was determined by exposing fish to conditions of progressively decreasing oxygen levels and recording the oxygen concentration at which loss of equilibrium occurred. The greenside darter was least tolerant to low oxygen levels in summer, with loss of equilibrium occurring at a mean O2 concentration of 3.39 mg l?1. Tolerances then increased through spring. A similar trend was observed for the fantail darter, with the lowest tolerance occurring in summer (2.36 mg ?1). and greatest tolerance in spring (2.03 mg l?1). The rainbow darter exhibited its greatest tolerance to low oxygen in summer and spring (1.64 and 1.93 mg l?1, respectively). Interspecific differences were greatest in summer, with greenside darters being the least tolerant to low oxygen levels and the rainbow darter being the most tolerant. No differences in tolerance among the species were noted in winter. The low oxygen tolerance exhibited in summer by the greenside darter may be due to a higher metabolic cost and a higher critical oxygen tension at maximal stream temperatures (>25° C). The observed differences in oxygen tolerance may influence the longitudinal distribution and habitat selection of darters, especially in the summer months.
