Summary: The transition from sexual reproduction to parthenogenesis has profound evolutionary consequences for sex-related traits, which are expected to decay. This study examined the population structures of pea aphids in cold-winter and mild-winter regions and found distinct multilocus genotypes (MLGs) representing cyclically parthenogenetic (CP) lineages in cold-winter regions and obligately parthenogenetic (OP) lineages in mild-winter regions. Male production was reduced in OP lineages, but there was no clear pattern observed for male reproductive success. These findings suggest that traits in OP lineages may degenerate due to lack of selection. The overall effective reproductive capacity of OP males may be due to recent sex loss or underestimated reproductive opportunities.

Summary: This study explores the repeated evolution in stickleback to identify key genomic loci that change during colonization of freshwater habitats by marine fish, showing rapid genotypic and phenotypic changes within 5 years. The speed and location of these changes can be predicted using empirical observations or fundamental genomic features, suggesting the importance of similar features for evolution across diverse taxa.

Summary: The study found significant differences in the morphology of epandrial posterior lobes and claspers of male individuals of the Drosophila simulans species clade, likely influenced by sexual selection. Through analysis of introgression lines and RNA-seq, new genes involved in the development and evolution of genital structures were identified, shedding light on the key genes regulating these evolutionary processes.

Summary: Results suggest that male humpback whales are capable of assessing eavesdropping risk and modifying their signaling behavior accordingly. The decisions made by humpback whale singers depend on a combination of social factors, including a social trigger, eavesdropping risk, and whether the singer is escorting a female. Humpback whale males are selecting the most appropriate singing strategy based on their assessment of the constantly changing, complex social environment.

Summary: This study hypothesizes that male-male courtship display evolved as a response to intrasexual competition, and the research found more evidence of eavesdropping, exploitation, and audience effect related to this competition.

Summary: Allele frequencies can change rapidly in natural populations. Recent studies of Drosophila melanogaster have shown that this phenomenon is more common than previously thought and is often driven by balancing selection. Large-scale population genomic studies have provided general insights into rapid evolutionary change, while single-gene studies have uncovered the functional and mechanistic causes of rapid adaptation.

Summary: By studying the preferences of both sexes in response to novel mating signals in grey treefrogs, evidence of sensory bias was found in both males and females: males exhibited more intense responses to complex stimuli, while females sometimes preferred complex stimuli.

Summary: The study demonstrates that female redeyed treefrogs are more likely to choose a male mating call when airborne sound is paired with its corresponding substrate vibrations. Furthermore, males of the same species are more aggressive towards and display a greater range of aggressive behaviors in response to bimodal calls than unimodal calls.

Summary: This study investigates the mechanisms underlying avian responses to heterospecific chick-a-dee calls. The results show that different resident bird species responded by approaching the chick-a-dee calls, and this response was not associated with their body mass or the similarity of their calls to chick-a-dee calls. The study demonstrates that these responses are innate and cannot be fully explained by learning, suggesting that the structural features of chick-a-dee calls are important.

Summary: Gene repertoire turnover is a characteristic of genome evolution. This study focuses on Macrostomum, a genus of flatworms, to analyze the presence/absence patterns of genes associated with different mating strategies. The results show that genes in the testis region of species that mate by hypodermic injection of sperm evolve more rapidly and have a lower probability of being observed in other species.

Summary: Behavioural traits are more likely to persist after the relaxation of selection pressure compared to morphological traits. However, little research has been conducted on non-adaptive vestigial behavioural variation. These vestigial behaviours may hinder adaptive evolution or contribute to future evolutionary trajectories. The persistence of these behaviours may be due to high levels of non-genetic variation and association with morphological features.

Summary: The study found that the peak song frequency of passerine species is related to body mass and sexual size dimorphism, but did not support the predicted relationship between frequency and habitat. This suggests that global variation in passerine song frequency is driven by evolutionary shifts in body size caused by natural and sexual selection, rather than by habitat-related selection on sound propagation.

Summary: This study demonstrates that plant density can induce age-dependent and sex-specific evolution in the ontogeny of vegetative organs. High-density and low-density populations of wind-pollinated plants showed divergence in vegetative traits after three generations of evolution, while reproductive traits remained unchanged. Furthermore, the expression of sexually dimorphic traits in young plants evolved differently in high-density and low-density populations.

Summary: This study investigates brain neuroanatomy in 18 wild guppy populations and finds extensive variation in brain size and brain region volumes across populations in different environments and with varying degrees of predation risk. Unlike laboratory studies, differences in allometric scaling of brain regions lead to variation in brain region proportions across populations. The study also reveals an association between sexual traits and brain size.

Summary: This study investigates the evolution of female ornamentation in Anolis lizards. The results show that female dewlaps are evolutionarily labile and species with larger females and reduced sexual size dimorphism are more likely to possess female dewlaps. Furthermore, the presence of female dewlaps influences diversification rates in anoles, but only as a secondary effect to a hidden state.

Summary: This study found that even a small number of male field crickets singing can reduce female response rates and prevent mate choice. This can be due to either acoustic interference or choice overload. The results suggest that in noisy natural environments, receivers may not always be able to express their well-documented mating preferences.

Summary: The study investigated the impact of acoustic signals on adult female mating preferences and found that some measures of female response are plastic and mediated by song quality, but effects were population specific and not entirely consistent with predictions.

Summary: When closely related species come into contact via range expansion, selection favors minimizing costly interspecies reproductive interactions. In a study on a toadlet species complex from northern Australia, population genomic data revealed the geographic origin and secondary contact, providing evidence for reproductive character displacement following range expansion.
