Sentence examples for mating propensity in from inspiring English sources

To investigate how population density might influence mating propensity in the two different ecotypes, we measured the degree of pair formation in experimentally created high and low densities.

Here we have demonstrated that in Asellus aquaticus, the adult sex ratio affects mating propensity in the novel stonewort ecotype but not in the ancestral reed ecotype.

However, from our experimental set up alone, we cannot distinguish whether the plastic increase in mating propensity in the stonewort (Fig. 3) is due to changes in the male behaviour, the female behaviour or both.

Assuming this is the natural mating propensity for the stonewort population under a balanced sex ratio, our results indicate that this ecotype adjusts mating propensity in both the male biased treatment (increasing mating propensity) and in the female biased treatment (decreasing mating propensity) (Fig. 3).

This increases mating propensity in females as they acclimatise to the vial [ 69].

In addition, we have previously documented lower mating propensity in the stonewort ecotypes [21].

Unlike Murphy et al [ 15], we detected no differences in mating propensity between the strains in each pair, but we had limited power to detect small differences.

Differences in mating propensity between the species in each pair would mean that a higher proportion of trials would result in zygotes when the species with a high mating propensity was "chooser" than when the species with a low mating propensity was chooser.

According to theory, we a priori expect mating propensity to increase in a lower population density and in a male biased population [cf. 20, 21], while we would expect mating propensity to decrease in a higher population density and in a female biased population [cf. 20,21].

Therefore, population density does not seem to affect the intrinsic differences in mating propensity between these two different ecotypes.

The differences in mating propensity under different sex ratios we have seen here might thus partly reflect flexible male mate choice.
