Summary: In this study, the researchers investigated the mating preferences of zebrafish and examined the influence of personality traits, such as boldness. The results showed that female zebrafish did not change their mate preferences by observing other females, and the mate copying behavior was not affected by personality traits.

Summary: Mate copying is a social phenomenon in which individuals evaluate opposite-sex others based on their relationship history. Women are aware of mate copying when evaluating potential male romantic partners, but seeing a man pictured with another woman does not provide additional information about his specific traits.

Summary: Research on wild northern map turtles reveals that males use public information to select mates and reduce sperm competition. They tend to avoid females affiliated with rival males, show eavesdropping behavior, and exhibit different interactions based on the presence or absence of rivals. Male-male interactions also play a role in reducing sperm competition, although the exact nature of these interactions remains unclear.

Summary: The SD allele in Drosophila melanogaster distorts Mendelian inheritance in heterozygous males by causing developmental failure of non-SD spermatids, leading to greater than 90% of sperm carrying SD. Sexual selection may limit the natural frequencies of SD when sperm competitive ability and female remating rate equal the values observed for one SD variant, SD-5, but is unable to explain the rarity of SD when parameterized with the values found for two other SD variants.

Summary: Under experimental conditions, female mate choice copying in fruit flies appears to be less robust than previously suggested, indicating a need for further research to assess its prevalence in different laboratory lines and natural populations.

Summary: Understanding the dynamics of mutual mate choice requires investigation of mate preferences of both sexes using a variety of designs, but fewer studies have focused on male choice in avian models. The results of the study suggest that experimental design can significantly impact the preferences of male zebra finches, highlighting the importance of considering design considerations in mate choice experiments.

Summary: The study found that in mate selection, women make choices based on a trade-off between social and personal information. Women no longer rely on others' choices when they have access to personal information about a potential mate.

Summary: Cryptic male mate choice refers to the differential allocation of resources by males to females during or after copulation. In the fruit fly Drosophila melanogaster, males mate longer and allocate more resources to larger females compared to smaller females. However, it is unclear if this increased investment in larger females has any impact on the males' subsequent matings.

Summary: Male superb lyrebirds create elaborate acoustic illusions to deceive avian receivers and prevent premature termination of crucial sexual interactions by females, thus triggering an intersexual co-evolutionary arms race between male mimetic accuracy and female discrimination. This suggests that the development of complex avian vocalizations known as 'song' may be driven by sexual conflict rather than female preference for male extravagance.

Summary: Sexual selection shapes the details and breadth of nature, but there is still much unexplained variation. Nonmodel organisms challenge our assumptions and push our understanding of sexual selection forward. Integrating empirical surprises is important for generating new questions and learning more about sexual selection.

Summary: The study found that mate choice copying behavior was only present in females, and existed in both males and females under high-quality models, but not under low-quality models. There was no significant difference between making decisions for oneself and for close friends, but there was a significant difference between making decisions for oneself and for strangers.

Summary: This article discusses how anisogamy leads to the emergence of separate sexes in multicellular organisms and introduces the phenomenon of sperm competition. In large populations, the sex ratio tends towards unity, while in small inbred populations, skewed sex ratios can occur. Recent research has revealed the mechanisms underlying highly skewed sex ratios in nematodes.

Summary: In principle, temporal fluctuations in sexual selection potential can be estimated by changes in reproductive success variance. However, little is known about how opportunity measures vary over time and the role of stochasticity. This study uses mating data to investigate temporal variation in sexual selection opportunity and finds that it changes rapidly, is influenced by random matings, and may be slowed by intrasexual competition. The study emphasizes the importance of simulations in understanding sexual selection and avoiding misinterpretation.

Summary: Sexual selection plays a crucial role in driving phenotypic diversity and diversification in animals. Female mate choice is the most common mechanism of sexual selection, but male-male competition and male mate choice also exist. Tactile traits are more widespread, while auditory traits are less common. These different types of sexual selection traits are mainly confined to arthropods and chordates, where accelerated rates of evolution are observed. Additionally, these traits are strongly correlated with each other in their evolution across animals. However, there is limited evidence supporting the idea that sexual selection traits drive large-scale patterns of diversification and species richness across all animals.
