Sentence examples for multiple matings and from inspiring English sources

In addition, the cost to females of mating, multiple matings, and male harassment to females was evaluated.

Last, the fitness costs to females by multiple matings and male harassment were investigated by comparing individually housed mated females and mated females exposed to males.

Previous work has shown that androchrome females are less fecund than infuscans females [ 22, 39] and this suggest that androchrome females would gain less from accepting multiple matings and consequently might be less willing to engage in additional mating interactions after they have mated once.

To test the effect of multiple matings and male harassment on fitness of females, two treatments were established: (1) 1 mated female (n = 58, paired with a single male companion for 2 days) kept alone and (2) 1 female and 1 male kept together until the female's death (n = 56).

Examples include the hypothesis that multiple matings and orgasms are physiologically beneficial to females and the hypothesis that females have sex with subordinate males to stop these males from leaving the social group.

They can collect sperm through multiple matings, and only the most competitive of this "sperm cocktail" will fertilize their eggs, says Nina Wedell, an evolutionary biologist at the University of Exeter in the United Kingdom.

Thus, it is possible both that matings failed to occur during the 24-h period that males and females were housed together, or indeed that multiple matings occurred and that this varied between conspecific and heterospecific matings, for instance if matings take longer to initiate in heterospecific crosses.

In Nasonia, post-copulatory behaviour by males greatly reduces female receptivity to future mating, making multiple matings by females uncommon and sperm competition relatively unimportant in this system (Leonard and Boake, 2008; Whiting, 1967).

By combining an experimental evolution approach with genomic techniques, we investigated the effects of single and multiple matings on female fecundity and gene expression.

Typically each male has zero or multiple matings to make, and there is a ranking for each mating, rather than for each male, such that matings for a given male are generally dispersed throughout the ranked list.

Males have a higher interest in multiple matings than females and may thus try to coerce females into being polygamous.
