Summary: The study revealed that different sexes of fish in sympatric hybridization contribute differently to behavioral isolation, possibly due to the impact of asymmetric postzygotic isolation and sex-specific preference costs.

Summary: This study highlights the formation of a set of closely related tree species in the Mascarene Islands that actively exchange genes, instead of evolving as completely independent species. The findings provide valuable insights into diversification and emphasize the importance of considering the entire network of potentially interfertile species.

Summary: Fish are affected by environmental variables and show physiological responses to maintain homeostasis. Xiphophorus maculatus can acclimatize and reproduce in saltwater, with offspring surviving when adults are gradually acclimatized to different salinities. Abrupt exposure to high salinity can be a stressor causing mortality.

Summary: Reproductive investment was initially believed to drive male mate preference, but even in polygynous species where male reproductive investments are relatively inexpensive, male preference has been observed. This study compared two livebearing fish species with differing reproductive investments and found that males exhibited different mate preference patterns based on their investment levels, with potential implications for future research on the interaction of reproductive investment with mate choice.

Summary: Genetic, ecological and simulation data demonstrate that the origin and coexistence of reproductively isolated sympatric groups in a fungus is driven by pleiotropic vegetative incompatibility genes under balancing selection.

Summary: The study found variation in epicuticular hydrocarbons (CHCs) as a potential factor in mate choice among adults of six Rhagoletis taxa, including the apple and hawthorn-infesting host races. Gas-chromatography-mass-spectrometry revealed 36 repeatable and quantifiable hydrocarbon components across all six fly taxa, with at least 53 different CHC compounds present, consisting of n-alkanes, mono-, dimethyl-, and trimethyl-alkanes, alkenes, and alkadienes. The results suggest that CHC variation may contribute to patterns of premating isolation between Rhagoletis taxa, potentially driven by sexual and host-related selection.

Summary: In many species, both males and females possess sexual signals, but most research focuses on understanding signal expression in males. However, increasing evidence demonstrates functional explanations for variation in female signals, highlighting the need for further research in this area.

Summary: This study found that sexual conflict can lead to coercive mating, while sexual selection through consensual mate choice can cause divergence in mate recognition cues among species, leading to more accurate species recognition. Male guppies and mosquitofish showed imperfect species recognition, but accurate recognition disappeared when attempting coercive copulation. Heterospecific sexual interaction had little effect on the fecundity of gravid females, suggesting that prepregnancy interactions likely contribute to the exclusion of mosquitofish by guppies.

Summary: The study compared the life performance and mating choice of Spodoptera litura reared on different diets, showing significant effects on developmental stages, fecundity, and mate choice. Artificial diet may promote behavioral isolation, impacting mating outcomes. Host plant preference during the larval stage may shape phenotypic plasticity and behavioral isolation in S. litura populations.

Summary: When populations come into secondary contact, speciation with gene flow can be promoted by 'magic trait' loci, which are pleiotropic loci subject to divergent ecological selection and non-random mating. In this study, a population genetics model is used to investigate the effectiveness of 'pseudomagic trait' complexes, physically linked loci with the same functions, in promoting premating isolation. Surprisingly, pseudomagic trait complexes, as well as physically unlinked loci, can lead to stronger assortative mating preferences compared to magic traits, as long as polymorphism is maintained.

Summary: A new evolutionary model proposes that juvenile females mistakenly imprint on male phenotypes that were not preferred by the female they copied, aiming to reconcile mismatches between theory and data.

Summary: In this study, two different approaches were used to investigate the presence of color polymorphism in the Cuban Limia fish. It was found that the frequency of black-spotted morphs was higher in brackish and saltwater environments, possibly due to higher predation pressure. The results suggest that habitat variation, particularly salinity levels, plays a key role in maintaining color polymorphism in this species.

Summary: This study used RNA-Seq to investigate the impact of an endocrine-disrupting pharmaceutical on reproductive behavior in wild guppies, revealing transcriptome-wide changes associated with courting behavior. Results showed that male guppies exposed to EE2 displayed significantly different gene profiles compared to other treatment groups, with the highest levels of courtship behavior. The study highlights the importance of exploring the effects of pharmaceutical compounds on gene networks rather than individual genes.

Summary: Researchers investigated the genetic architecture and evolutionary loss of a sexually selected ornament in swordtail fish, finding that the sword ornament is polygenic and one major-effect quantitative trait locus explains a significant portion of the variation. They also identified candidate genes related to fin regeneration and growth within the large QTL interval. Selection against the sword ornament was observed in natural hybrid populations.

Summary: The study evaluates the robustness of geographic cline analysis under different evolutionary scenarios using simulations. It found that drift can distort cline shapes and increase false positive rates for signatures of selection, particularly in older hybrid zones with low migration rates. The results suggest that geographic clines are most useful for outlier analysis in young hybrid zones with large populations of hybrid individuals.

Summary: Darwin's theory of sexual selection revolutionized our understanding of sex and evolution, highlighting the role of mating and fertilization in driving species diversification. Both male and female mate choice play a crucial role in sexual selection, contrary to the contemporaries' dismissal of Darwin's idea. Mate choice mechanisms can evolve in response to selection pressures unrelated to sexual selection, and the coevolution of traits and preferences can occur regardless of the fitness effects on the choosers. The interplay between traits, preferences, social effects, and broader-scale processes like reproductive isolation and population responses to environmental change determine the influence of sexual selection and mate choice.

Summary: With the direct or indirect effects of human activity on nearly all life forms on Earth, it is crucial to understand how organisms adapt to human-induced environmental change. Domestication, as an early event in the Anthropocene, provides insights into the response of animal populations to human-altered environments. Evaluating domestication as a source of anthropogenic selection can inform conservation efforts and shed light on mechanisms of behavioral adaptation.

Summary: The negative consequences of inbreeding have led animal biologists to assume that mate choice is generally biased against relatives. However, inbreeding avoidance is highly variable and by no means the rule across animal taxa. Balancing inbreeding avoidance with conspecific mate preference may drive the evolution of multivariate sexual communication.
