Currents Produced By The Gills Of Mayfly Nymphs
Currents Produced By The Gills Of Mayfly Nymphs BABAK and Foustka1 were able to show that the movements of the gills of ephemerid nymphs were dependent on the oxygen tension of the water. Later, Dodds and Hisaw2 demonstrated a relation between the gill area per gram weight of the animal and the oxygen tension of the water inhabited by these animals. That the currents produced by the gills might differ in different species, and that such currents might have an adaptive significance, appear to have escaped notice.
