Abstract
I conducted an experiment to assess the effects of aeration on the growth of bullfrog tadpoles (Rana catesbeiana). Tadpoles in the non-aerated treatment grew slower than tadpoles in the aerated treatment. Tadpoles in the nonaerated treatment were observed at the water's surface more often and on food resources less often than tadpoles in the aerated treatment. Oxygen concentrations in natural aquatic habitats varied greatly (encompassing the range of the experimental treatments), suggesting the results of this study may be applicable to natural situations. The results suggest oxygen content (and/or disturbance) of aquatic habitats may influence the distribution and success of Rana catesbeiana.
