Data from: Love the one you're with: proximity determines paternity success in the barnacle Tetraclita rubescens

A species' mating system sets limits on the strength of sexual selection. Sexual selection is widespread in dioecious species, but is less well documented in hermaphrodites, and may be less important. We used four highly polymorphic microsatellite markers to assign paternity to broods of the hermaphroditic eastern Pacific volcano barnacle Tetraclita rubescens. These data were used to describe the species' mating system and to examine factors affecting male reproductive success. Tetraclita can sire broods over distances of 11.2 cm, but proximity to the sperm recipient had a highly significant effect on the probability of siring success. There was no effect of body size or the mass of male reproductive tissues on siring success. Broods showed relatively low frequencies of multiple paternity; even at high densities, 75% of broods had only one father. High frequencies of single-paternity broods imply either that this species does not compete via sperm displacement, or that sperm displacement is extremely effective, potentially explaining the lack of a positive relationship between male investment and paternity. In addition, there was low variance in siring success among individuals, suggesting a lack of strong sexual selection on male traits. Low variance among sires and the strong effect of proximity are likely driven by the unusual biology of a sessile copulating species.

Data from: Love them all: mothers provide care to foreign eggs in the European earwig Forficula auricularia

The rejection of foreign individuals is considered a central parameter in the evolution of social life. Within family units, parents are typically thought to reject foreign offspring to ensure that their investment into care is directed towards their own descendants. Whereas selection for such kin bias is expected to be high when parental care is extended and involves numerous and energetically costly behaviours, it can be reduced when the acceptance of foreigners provide subsequent benefits to offspring and when alternative parental strategies limit the risk of clutch parasitism. In this study, we investigated the outcome of these conflicting selection pressures in the European earwig. Our results overall demonstrate that mothers do not eliminate foreign eggs, provide the same level of care to both foreign and own eggs (egg grooming, egg defense and maternal return) and pay the same costs of care in terms of weight loss and immunity when tending each type of eggs. We also show that foreign and own eggs exhibit similar development time, hatching success and lead to comparable juvenile quality. Interestingly, our results reveal that tending eggs (of any origin) reduces mothers' weight loss during this long period, possibly due to egg cannibalism. Hence, these findings emphasize the difficulty to predict the occurrence of kin bias, and stress the need to broaden our knowledge on the net benefits of egg rejection for parents to better understand the general importance of kin bias in the evolution of pre-hatching parental care.

Data from: Home loving boreal hare mitochondria survived several invasions in Iberia: the relative roles of recurrent hybridisation and allele surfing

Genetic introgression from a resident species into an invading close relative can result from repeated hybridisation along the invasion front and/or allele surfing on the expansion wave. Cases where the phenomenon is massive and systematic, such as for hares (genus Lepus) in Iberia, would be best explained by recurrent hybridisation but this is difficult to prove since the donor populations are generally extinct. In the Pyrenean foothills, Lepus europaeus presumably replaced Lepus granatensis recently and the present species border is parallel to the direction of invasion, so that populations of L. granatensis in the contact zone represent proxies of existing variation before the invasion. Among three pairs of populations sampled across this border, we find less differentiation of mtDNA across than along it, as predicted under recurrent hybridisation at the invasion front. Using autosomal microsatellite loci and X and Y-linked diagnostic loci, we show that admixture across the border is quasi-absent, making it unlikely that lack of interspecific mtDNA differentiation result from ongoing gene flow. Furthermore, we find that the local species ranges are climatically contrasted, making it also unlikely that ongoing ecology-driven movement of the contact account for mtDNA introgression. The lack of mtDNA differentiation across the boundary is mostly due to sharing of mtDNA from a boreal species currently extinct in Iberia (Lepus timidus) whose mitochondria have thus remained in place since the last deglaciation despite successive invasions by two other species. Home loving mitochondria thus witness past species distribution rather than ongoing exchanges across stabilised contact zones.

Finding love: fruit fly males evolving under higher sexual selection are inherently better at finding receptive females

Courtship is an important component of male reproductive behaviour that enables males to learn about the suitability of their mating partners. Experimental evidence suggests that Drosophila melanogaster males can learn to modify their courtship behaviour based on their prior experience with unreceptive females. This courtship learning is expected to provide a fitness advantage to males and could therefore evolve given suitable heritable variation. We investigated the role of sexual selection in the evolution of courtship learning ability of males, using populations of D. melanogaster evolving under high and low levels of sexual selection for over 170 generations. We exposed males from both types of population to unreceptive females and then tested their ability to discriminate between receptive and unreceptive females in a complex mating environment. After being exposed to unreceptive females, males from both types of population (1) courted females less (both receptive and unreceptive), (2) took longer to initiate courtship, but took less time to start mating after initiating courtship and (3) increased the proportion of courtship directed towards receptive females, indicating the ability of both types of male to learn from experience. We did not find any difference in the courtship learning ability of males from the two types of population. However, males from populations with higher levels of sexual selection were better able to recognize and court receptive females, even when they were not previously exposed to unreceptive females. Taken together, these results show that sexual selection may not result in improved learning abilities but can lead to the evolution of an improved innate ability of males to assess the receptivity of females.
