Effect of ambient temperature on persistence. The figure depicts the relationship between temperature and the number of dives per a cluster and b aquatic activity session for females (red) and for males (black). The slopes for significant relationships for females are included in the figures (clusters: persistence [no. of dives] = −0.53(ambient temperature)[oC] + 21.93; F1,8 = 8.89, R2[adjusted] = 0.47, P = 0.0175. AAS: persistence [no. of dives] = −1.76 (ambient temperature)[°C] + 58.92; F1,8 = 6.19 R2[adjusted] = 0.37, P = 0.038).
