Effects of collection site and acclimatization treatment on cytochrome c oxidase activities in tissues of the African cyprinid Barbus neumayeri. Samples were collected from Inlet Stream West or Rwembaita Swamp and acclimatized in the normoxic stream site (open bars) or the hypoxic swamp site (filled bars) for four weeks. P values are from two-way ANOVAs with site of origin and acclimatization treatment as main effects (see Methods). Error bars represent one SEM and sample sizes for each tissue are given above the bars.
