Summary: Different sperm traits between Lampetra fluviatilis and Lampetra planeri can affect male reproductive success and gene flow. However, there is no evidence for cryptic female choice or postmating prezygotic barriers, explaining the partial reproductive isolation between the two lamprey ecotypes.

Summary: The study found that host-associated incompatibility contributes 1.5 times more than Wolbachia-induced incompatibility in reducing hybrid production, and the two sources of incompatibility act through different mechanisms in an additive fashion. In addition, near-complete F1 hybrid sterility was observed between populations of the two forms, with no contribution from Wolbachia.

Summary: Comparison of global gene expression patterns in con- and heterospecifically mated Drosophila mojavensis and Drosophila arizonae suggest that mating-responsive genes with divergent expression also exhibit more disrupted transcriptional profiles in heterospecifically mated females, providing further insight into the evolution of postmating-prezygotic reproductive isolation.

Summary: Sexual barriers associated with mate choice are often linked with ecological isolation between species, but the strength of sexual isolation can be difficult to assess. In a study of two marine isopod species, sexual isolation was found to be strong regardless of the presence of ecological isolation, but was asymmetric and did not completely prevent gene flow between the species. This suggests that sexual isolation alone may not be enough for complete speciation.

Summary: This study confirmed the prevalent view on the evolution of reproductive barriers in haplodiploid spider mites and found variations and asymmetries in the degree of reproductive isolation, emphasizing the importance of reinforcement of prezygotic reproductive isolation through incompatibility and the role of cytonuclear interactions for reproductive isolation in haplodiploid spider mites.

Summary: This study develops a mathematical model to predict the effect of relative species abundance and mate choice errors on hybridization patterns. The results show that when mate choice errors are low, hybridization occurs most frequently when one of the hybridizing species is rare, while when mate choice errors are high, hybridization frequency is highest when species occur in equal proportions. In addition, females of the less abundant species play a significant role in mixed-species matings.

Summary: Researchers filled the gap in literature by analyzing hybridization in natural populations using databases and case studies, indicating that citizen scientists underreport hybrids compared to experts. The results suggest that geographic range and cryptic hybrids need to be considered when estimating hybridization rates in birds.

Summary: Estimating per-individual rates of hybridization in wild birds involves challenges related to the definition of hybrid, distinguishing between shared DNA sequences and ongoing hybridization, the dangers of focusing only on known hybrid zones, and the implications of very low rates of per individual hybridization. Recognizing hybrids based on phenotype, quantifying ongoing between-species mating, and not prejudging which birds are presumed to engage in hybridization are important considerations in this field. Additionally, evidence for strong prezygotic sorting does not necessarily indicate that mate choice drives speciation.

Summary: This study investigates the proteomic composition of the female reproductive tract (FRT) tissue and luminal fluid before and after mating in Drosophila melanogaster, revealing distinct characteristics between the fluid proteome and tissue proteome. The fluid proteome is encoded by genes with higher FRT gene expression levels and tissue specificity, enriched for metabolic functions, and exhibits significant postmating compositional changes. These findings enhance our understanding of secretion mechanisms in the FRT, provide insights into female contributions to reproductive interactions, and underscore the importance of proteomic approaches in studying the dynamics of the FRT environment.

Summary: Saltmarsh sparrow and Nelson's sparrow differ in ecological niche, mating behavior, and plumage, but they hybridize where their breeding distributions overlap, resulting in substantial genomic introgression. Although few hybrids are currently produced, strong postcopulatory sexual selection on sperm cells may explain the divergence in sperm length between the two species in the hybrid zone. Sperm appears to act as a prezygotic barrier, while sperm from hybrids was unexceptional as a postzygotic barrier.

Summary: Speciation is driven by reproductive isolating barriers, with prezygotic barriers generally stronger than postzygotic ones. Ecological divergence and extrinsic factors play important roles in plant speciation and species boundary maintenance.

Summary: Divergence in phenotypes and reproductive environments may contribute to postmating prezygotic isolation between species. In this study, differences in sperm morphology and velocity were examined in two hybridizing passerine species. Additionally, the proteome of the female reproductive tract fluid was characterized for the first time. The results showed that the size differences in the flagellum and acrosome of the sperm did not affect sperm velocity. Furthermore, the reproductive tract fluid did not have different effects on the velocity of conspecific and heterospecific sperm. These findings suggest that the observed differences may impact other postcopulatory processes related to sperm storage, longevity, or sperm-egg interaction.

Summary: This study found the presence of precopulatory behavioral isolation in tidepool copepod species, indicating that interspecific differences in behavior during the mating process can lead to mating failure. These findings suggest that prezygotic behavioral factors play an important role in the isolation of copepod species.

Summary: Hybridisation between different species can result in maladapted or nonviable offspring due to genetic incompatibilities. Mating with close relatives or self-fertilisation can lead to inbreeding depression. Therefore, organisms need to carefully choose their mating partners to avoid both of these problems. In plants, pollen-pistil interactions play a crucial role in avoiding inbreeding and hybridisation with other species. This review focuses on the mechanisms of pollen-pistil interactions and their importance in maintaining species integrity.

Summary: Comparative genomics has shown that sexual selection plays a significant role in evolutionary divergence and speciation, but accurately determining the relative importance of natural selection, demography, and neutral processes is challenging. Experimental evolution allows for controlled treatments over multiple generations to investigate genomic divergence.

Summary: For 43 Drosophila species, global distributions better match male-sterilizing temperatures than lethal temperatures. This suggests that species distributions may be determined by thermal limits to reproduction, rather than survival, potentially underestimating the impacts of climate change for many organisms.

Summary: The study reveals that fertilization mode is a key factor influencing the evolution of sperm length across animals. Species with sperm diluted in aquatic environments (external fertilizers and spermcasters) have shorter sperm, while species with sperm directly transferred to females (internal fertilizers) have longer sperm. Additionally, sperm length evolves faster and with more adaptive shifts in species where sperm operate within females (e.g. spermcasters and internal fertilizers).
