Sentence examples for copulation duration of from inspiring English sources

Comparisons of parental and hybrid males copulation durations showed no significant reduction in copulation duration of F1QW males.

Copulation duration of the original mating did not differ between females that went on to remate and those that never remated (all data pooled, square root transformed, N = 893, Welch's t-test, t 1, 188 = 0.617, p = 0.538).

For instance, it may be the result of failure by the male to successfully inseminate the female during copulation (all species reported to show mating failure have complex genitalia, and a minimum copulation duration of 1h is necessary for sperm transfer: Micholitsch et al. 2000; Higgins et al. 2009; Dougherty and Shuker 2014).

Since copulation duration of F1QW and F1WQ hybrid males is similar to that of the female parent used to produce each particular hybrid, the result suggests that copulation duration is strongly influenced by the X-chromosome origin of the hybrid genome.

The copulation duration of Greek males was only increased when males were exposed to four or more rivals prior to mating (Tukey post-hoc comparisons with lone male: vs. one rival, p = 0.741; vs. four rivals, p < 0.005; vs. nine rivals, p < 0.005).

Given that there were significant differences in copulation duration of the sterile F1QW male hybrids based on whether they mated to D. w. willistoni or D. w. quechua females (F1,58 = 4.27; P = 0.004) (Additional file 1: Table S1), we re-analyzed the data by partitioning the mating types by both females and males involved.

While there was not a significant reduction of copulation duration for the F1QW hybrid males with respect to the D.w. quechua parents, it is still possible that they either failed to transfer sperm or that there was either passive sperm spillage or active dumping by females.

In addition to swelling size, we noted the following variables: identity of mating partners, presence/absence of copulation call, temporal occurrence of call in relation to copulation, aggressive behaviours following a copulation, duration to next copulation and composition of the audience during copulation.

If the male mounted the female, the time in the mating position (used as a proxy of copulation duration) and the number of pedipalp insertions was recorded.

Copulation duration data, presence of sperm in female storage for interrupted copulations, presence of sperm in storage of fully mated females, and data on female sperm spillage.

Furthermore, studies on sexual selection and male-female coevolution in Finnish D. montana suggest a conflict of interest between the sexes in the length of copulation duration [ 38].
