Data from: Siring success in kangaroos: size matters for those in the right place at the right time
In polygynous species, male reproductive success is predicted to be monopolized by a few dominant males. This prediction is often not supported, suggesting that ecological and alternative mating tactics influence siring success. The spatiotemporal distribution of individuals and the number of males competing for each receptive female are often overlooked, because they are difficult to monitor in wild animals. We examined how spatial overlap of female-male pairs, the time spent by a male on the breeding site, number of competitors and morphological traits influence siring probability in eastern grey kangaroos (<i>Macropus giganteus</i>). We compared home range overlap for 12,208 dam-male pairs and 295 known dam-sire pairs to define local competitive groups and to estimate every male's opportunity to sire the young of each female. We compared models considering morphological traits relative to the entire population or to local competitive groups. Including local competition improved model performance because it estimated the intensity of competition and compared each male's morphological traits to those of its competitive group. Regardless of size, males can increase their probability to sire a young by increasing their <i>mating opportunity</i> relative to the mother. We underline the importance of considering spatial structure to assess the intensity of competition in species where males cannot equally access all females in a population. The estimation of mating opportunity and intensity of local competition improves our understanding of how morphological traits affect siring success when each mating event involves a different set of competing males, a characteristic of most wild species.

Data for: Ranking the importance of factors driving siring success during sperm competition in the North African houbara bustard
<p><span>Sperm competition is a powerful force driving the evolution of ejaculate and sperm traits. However, the outcome of sperm competition depends on many traits that extend beyond ejaculate quality. Here, we studied male North African houbara bustards (</span><em><span>Chlamydotis undulata undulata</span></em><span>) competing for egg fertilization, after artificial insemination, with the aim to rank the importance of 14 parameters as drivers of siring success. Using a machine learning approach, we showed that traits independent of male quality (i.e., insemination order, delay between insemination and egg laying) were the most important predictors of siring success. Traits describing intrinsic male quality (i.e., number of sperm in the ejaculate, mass motility index) were also positively associated with siring success, but their contribution to explaining the outcome of sperm competition was much lower than for insemination order. Overall, this analysis shows that males mating at the last position in the mating sequence have the best chance to win the competition for egg fertilization. This raises the question of the importance of female behavior as determinant of mating order. </span></p>

Data for: Experimentally advancing morning emergence time does not increase extra-pair siring success in blue tit males
<p>Extra-pair paternity occurs frequently in socially monogamous birds, but there is substantial variation in extra-pair siring success among males. Several studies have shown that siring success relates to the timing of morning activity, with the earliest active males being more successful, which suggests that early activity is important for acquiring extra-pair copulations. However, these studies are correlational, and it therefore remains unclear whether the relationship between timing and extra-pair siring success is causal. An alternative explanation is that successful extra-pair sires tend to be active earlier (e.g. because they are of high quality or in good condition), but that early activity in itself does not increase siring success. We experimentally advanced the emergence time of male blue tits by exposing them to light about half an hour before their natural emergence time. Although males that were exposed to the light treatment emerged from their roost substantially earlier than males that were exposed to a control treatment, light-treated males were not more likely to sire extra-pair offspring. Furthermore, whereas control males showed the expected relation between emergence time and siring success (although not statistically significant), there was no relation between emergence time and extra-pair siring success among light-treated males. Our results challenge the hypothesis that the timing of morning activity per se is an important factor underlying extra-pair siring success.</p>
