For nests that produced at least one chick, T f depended on whether the parents deserted their broods and on chick survival. The asterisks show peak correlations in each year.

Advance article alerts. The aim of this study was to characterize social interactions and calculate OSR in a wild population of this species and to assess, for the first time, the effects of familiarity and body size on subsequent mate choice in both males and females in a free-living population.

Second, snowy plovers have variable breeding behavior: both sexes incubate Vincze et al. Male choice and sperm competition as constraints on polyandry in the red-necked phalarope Phalaropus lobatus. View Metrics. If a population is male biased then there are a lot more rival males to compete for a mate, meaning that those who have a mate already are more likely to guard the mate that they have.

All parameters. Trials were undertaken in 5 sets of 4 days each 1 day for animal collection followed by 3 days of trials.

  • Oct 01,  · The intensity of competition for access to mates will become more intense as the OSR (operational sex ratio) deviates from 50%, in either direction. Any excess of either sex will be least when the OSR is around 50%.Cited by: The operational sex ratio (OSR) is central in predicting the intensity of mating competition and which sex is competing for which. Thanks to recent theoretical and empirical advances, particularly by exploring the concept of OSR, sexual selection studies today are becoming more fine-tuned and writenshare.info by:
