202 CHAPITRE 5. ADAPTATIONS RESPIRATOIRES DE S. MESATLANTICA FIG. 5.14 – Urate effect on Segonzacia mesatlantica Hc affinity. Functional parameters P 50 and n 50 were measured with several urate concentrations. Experiments were performed at 15°C on physiological saline buffer washed hemocyanin from a single individual. Given the smaller pH range and number of points compared to the L-lactate experiment, simple linear regression was used to fit the data. For comparison, data for Hc from the shore crab Carcinus maenas is also presented on the graph (Lallier et Truchot, 1989).

5.4. MANUSCRIT : RESPIRATORY ADAPTATIONS OF S. MESATLANTICA 203 FIG. 5.15 – Magnesium effect on Segonzacia mesatlantica and Carcinus maenas Hc affinity. Functional parameters P 50 and n 50 were measured with several magnesium concentrations for each species. Experiments were performed at 15°C on physiological buffer washed hemocyanin from a single individual. Data were fitted using simple linear regression. The magnesium effect is quantified by the slope ∆log(P 50) ∆log[Mg 2+ ] .
