Population genomics and sexual signals identify reproductive interference in Uperoleia
<p>When closely related species come into contact via range expansion, both may experience reduced fitness as a result of the interaction. Selection is expected to favor traits that minimize costly interspecies reproductive interactions (such as mismating) via a phenomenon called reproductive character displacement (RCD). Research on RCD frequently assumes secondary contact between species, but the geographic history of species interactions is often unknown. Landscape genomic data allows tests of geographic hypotheses about species origins and secondary contact through range expansion. We used landscape genomic data from single nucleotide polymorphisms (SNPs), mitochondrial sequence data, advertisement call data, and morphological data to investigate a species complex of toadlets (<em>Uperoleia borealis, U. crassa, U. inundata</em>) from northern Australia. Although the three species of frogs were morphologically indistinguishable in our analysis, we determined that <em>U. crassa</em> and <em>U. inundata</em> form a single species (synonymized here) based on an absence of genomic divergence. SNP data identified the phylogeographic origin of <em>U. crassa </em>as the Top End, with subsequent westward invasion into the range of <em>U. borealis</em> in the Kimberley. We identified six F1 hybrids, all of which had the <em>U. borealis</em> mitochondrial haplotype, suggesting unidirectional hybridization. Consistent with the RCD hypothesis, <em>U. borealis</em> and <em>U. crassa</em> sexual signals differ more in sympatry than in allopatry. Hybrid males have intermediate calls, which likely reduces attractiveness to females. Integrating landscape genomic data, mitochondrial sequencing, morphology, and behavioral approaches supplies us an unusually detailed collection of evidence for reproductive character displacement following range expansion and secondary contact.</p>

Data from: Co-occurrence of related asexual, but not sexual, lineages suggests that reproductive interference limits coexistence
We used randomizations to analyse patterns of co-occurrence of sexual and apomictic (asexual) members of the North American Crepis agamic complex (Asteraceae). We expect strong asymmetry in reproductive interactions in Crepis: apomicts produce clonal seeds with no need for pollination and are not subject to reproductive interference from co-occurring relatives. However, because they still produce some viable pollen, apomicts can reduce reproductive success of nearby sexual relatives, potentially leading to eventual local exclusion of sexuals. Consistent with this, randomizations reveal that sexuals are over-represented in isolated sites, while apomicts freely co-occur. Incorporation of taxonomic and phylogenetic evidence indicates that this pattern is not driven by local origins of asexuals. Our evidence that patterns of local co-occurrence are structured by reproductive interference suggests an underappreciated role for these interactions in community assembly, and highlights the need for explicit tests of the relative contributions of ecological and reproductive interactions in generating patterns of limiting similarity.

Data from: Sexual selection in complex communities: integrating interspecific reproductive interference in structured populations
The social structure of populations plays a key role in shaping variation in sexual selection. In nature, sexual selection occurs in communities of interacting species, however heterospecifics are rarely included in characterisations of social structure. Heterospecifics can influence the reproductive outcomes of intrasexual competition by interfering with intraspecific sexual interactions (interspecific reproductive interference; IRI). We outline the need for studies of sexual selection to incorporate heterospecifics as part of the social environment. We use simulations to show that classic predictions for the effect of social structure on sexual selection are altered by an interaction between social structure and IRI. This interaction has wide-ranging implications for patterns of sexual conflict and kin-selected reproductive strategies in socially structured populations. Our work bridges the gap between sexual selection research on social structure and IRI, and highlights future directions to study sexual selection in interacting communities.
Data from: Phenotypic plasticity of mate recognition systems prevents sexual interference between two sympatric leaf beetle species
Maladaptive sexual interactions among heterospecific individuals (sexual interference) can prevent the coexistence of animal species. Thus, the avoidance of sexual interference by divergence of mate recognition systems is crucial for a stable coexistence in sympatry. Mate recognition systems are thought to be under tight genetic control. However, we demonstrate that mate recognition systems of two closely related sympatric leaf beetle species show a high level of host-induced phenotypic plasticity. Mate choice in the mustard leaf beetles, Phaedon cochleariae and P. armoraciae, is mediated by cuticular hydrocarbons (CHCs). Divergent host plant use causes a divergence of CHC phenotypes, whereas similar host use leads to their convergence. Consequently, both species exhibit significant behavioral isolation when they feed on alternative host species, but mate randomly when using a common host. Thus, sexual interference between these syntopic leaf beetles is prevented by host-induced phenotypic plasticity rather than by genotypic divergence of mate recognition systems.
Data from: Heterostyly promotes disassortative pollination and reduces sexual interference in Darwin's primroses: evidence from experimental studies
Different strategies to reduce selfing and promote outcrossing have evolved in hermaphroditic flowers. Heterostyly, a complex floral polymorphism that occurs in at least 27 families of angiosperms, is hypothesized to achieve both goals by optimizing cross-pollination (via disassortative pollen transfer) and restricting gamete wastage to autogamy (via the reduction of sexual interference between male and female organs). In heterostylous flowers, the reciprocal positioning of sexual organs in different morphs and the pollen incompatibility-system within flower or between flowers of the same morph are thought to optimize both male and female functions, reducing the conflicts inherent to the occurrence of both sexual organs in the same reproductive unit. Specific elements of the disassortative-pollination and sexual-interference hypotheses have been tested individually before. However, despite the long-standing interest in heterostyly – ever since Darwin's seminal work on primroses – the predictions derived from these two hypotheses have never been experimentally and systematically examined in the same system. Using distylous primroses (Primula elatior, P. vulgaris) we compare pollen transfer (i) between reciprocal and non-reciprocal flowers; (ii) from anthers onto different parts of the pollinator's body; (iii) within flower and between flowers of the same morph. We further test whether (iv) anther-stigma distance correlates with self-pollen transfer; (v) seed-set differs after pollinations with compatible, incompatible, and both pollen types. Reciprocal herkogamy promotes differential placement of pollen onto different parts of the pollinator's body, thus effecting transfer of more pollen to reciprocal than non-reciprocal stigmas and realizing the key predictions of the disassortative-pollination hypothesis. However, short-styled flowers transfer pollen more disassortatively than long-styled flowers in both species, whereas long-styled flowers export more pollen to non-reciprocal than reciprocal stigmas in P. vulgaris, thus compromising male function in this species. Furthermore, larger distance between sexual organs lowers self- and intra-morph pollination and the pollen incompatibility-system decreases seed production after self-pollination, thus diminishing sexual interference. Our results help us understand how the morphological and physiological components of heterostyly contribute to optimizing pollen transfer and minimizing self- and intra-morph pollination, thus promoting more efficient outcrossing in species with this floral polymorphism.
