Sentence examples for copulation rate from inspiring English sources

Dreghorn males had a lower copulation rate, lower display rate, and lower theft rate, and they received less rainfall during the experiment (rainfall: Dreghorn, 0 mm; Townsville, 10 mm; N.R. Doerr, unpublished data, Queensland Bureau of Meteorology, personal communication).
The copulation rate was higher, though not significantly, when males were supplemented (0.09 ± 0.11 copulations per day) than under control conditions (0.02 ± 0.08 copulations per day; Z = −1.859, n = 14, P = 0.063).
