Summary: Darwin's theory of sexual selection, proposed one hundred fifty years ago, focuses on female preferences for elaborately ornamented males due to their taste for beauty. Research has since explored fitness advantages, sensory ecology, signal design, neural circuits, and neurochemistry, providing insight into the mechanisms behind mate choice. Recent studies inspired by human research in psychophysics, behavioral economics, and neuroaesthetics have further advanced our understanding of mate choices.

Summary: A novel application of acoustic camera technology was used to investigate the influence of individual wood frogs' calls on chorus properties and mating opportunities. The results showed that males and females preferred choruses with low variance in dominant frequency, and females preferred choruses with low mean peak frequency. Field studies revealed that more egg masses were laid in ponds where male frogs chorused with low variance in dominant frequency.

Summary: This study revealed the relative importance of male and female identity in male courtship behavior, as well as the increased male responsiveness to stimulus females as the breeding season progressed. Furthermore, the results suggest that invitation latency is a consistent courtship attribute in males that can be adjusted plastically according to perceived female quality and environmental conditions.

Summary: In contrast to pre-mating sexual selection, little theoretical research has focused on the coevolution of postmating traits via cryptic female choice. This study used simulation models to investigate the impact of nondirectional cryptic female choice on male-mediated postmating processes, as well as the interaction between sperm competition risk, cryptic female choice strength, and sperm traits. The results showed that incorporating cryptic female choice can result in reduced male investment in ejaculates. It also revealed that genetic correlations between cryptic female choice and sperm traits can evolve even with weak cryptic female choice and low sperm competition risk.

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: The aesthetic preferences of potential mates play a significant role in the evolution of elaborate ornaments. Females tend to prefer ornaments that signal a male's quality and have preexisting perceptual biases. The costs of preference expression and the potential genetic benefits associated with offspring attractiveness are important factors in shaping female preferences.

Summary: The evolution of sexual signals is influenced by whether one or both sexes engage in mate choice. In the case of the noctuid moth Chloridea virescens, both males and females emit sex-specific pheromones, but females tend to choose larger males for mating. Female mate choice in this moth species is not influenced by male pheromones, and females use behavior and tactile stimuli to make decisions during courtship.

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.

Summary: Sexual competition depends on the ability to impress, drive away, or attract conspecifics. The selective environment, which consists of evaluations made by individuals, can be hedonic or affective. The range of evaluations can be from positive to negative, rather than just positive to neutral. This suggests that mate choice selection may be stronger than previously thought.

Summary: Male insects use female sex pheromones to assess female quality and reproductive potential. The ratio of components in the sex pheromone blend conveys honest information about the female's phenotypic conditions, and males use this information to choose their mates. Pheromones have evolved as sexual traits under directional, sexual selection, with the blend serving as a multicomponent signal reflecting the female's current condition.

Summary: There is no consensus on why females prefer mates with rare phenotypes, but sexual selection can maintain genetic variation. We examined the fitness consequences of female preference for rare male color patterns in Trinidadian guppies over 10 generations and found that rare males have a reproductive advantage and mating with them gives females an indirect fitness advantage through the success of their sons. However, the fitness benefit disappears for grandsons as the rare phenotype becomes common. Contrary to prevailing theory, our study shows that female preference can be maintained through indirect selection.

Summary: The study examines the relationship between post-pairing male behaviors and female trait evolution using theoretical models. It finds that male mate choosiness can have surprising influence on the evolution of costly female traits. The study suggests that choosy males can have different post-pairing behaviors, which has been overlooked in previous studies. The findings show that both male preferences and female traits can evolve more easily than previously expected.

Summary: The study found that the impact of partner and alloparental support on child social development is mainly mediated by its effects on parental psychological condition and parenting style, which subsequently improve children's outcomes. However, a greater availability of childcare support was directly associated with more behavioral difficulties in children.

Summary: This study examines the geographic variation of traditional songs in the Ryukyu Archipelago, Japan, and explores the cultural evolution of music. The research suggests that cultural traits, such as music, are more likely to be horizontally transmitted between populations in this region than linguistic traits. Additionally, the social context in which songs are sung influences their transmission within and between populations. Interestingly, the study finds no association between the variation of songs and genetic diversity, but a correlation with linguistic diversity.

Summary: The spatial distribution of human culture reflects both shared ancestry and transmission among neighboring populations. This study proposes a spatially explicit model using Bayesian statistics to analyze the geographic variations in cultural repertoire. By incorporating a network model representing populations, the method considers both horizontal transmission and mutation of cultural traits. The results show that the proposed algorithms can compute the posterior distribution of model parameters within a reasonable computation time.

Summary: Natural movement is related to health, but it is difficult to measure. Existing methods cannot capture the full range of natural movement. Comparing movement across different species helps identify common biomechanical and computational principles. Developing a system to quantify movement in freely moving animals in natural environments and relating it to life quality is crucial. This study proposes a theoretical framework based on movement ability and validates it in Drosophila.

Summary: Fisher's geometric model is a useful tool for predicting key properties of Darwinian adaptation, and here it is applied to predict differences between the evolution of altruistic versus nonsocial phenotypes. The results suggest that the effect size maximizing probability of fixation is smaller in the context of altruism and larger in the context of nonsocial phenotypes, leading to lower overall probability of fixation for altruism and higher overall probability of fixation for nonsocial phenotypes.

Summary: Cell competition is a process where cells interact in multicellular organisms to determine a winner or loser status, with loser cells being eliminated through programmed cell death. The winner cells then populate the tissue. The outcome of cell competition is context-dependent, as the same cell type can win or lose depending on the competing cell type. This paper proposes a mathematical framework to study the emergence of winner or loser status, highlighting the role of active cell death and identifying the factors that drive cell competition in a cell-based modeling context.

Summary: This study forecasts the evolution of the COVID-19 pandemic in Germany using a network-based inference method and compares it with other approaches. The results show that the network-inference based approach outperforms other methods in short-to mid-term predictions, even with limited information about the new disease. Furthermore, predictions based on the estimation of the reproduction number in Germany can yield more reliable results with increasing data availability, but still cannot surpass the network-inference based algorithm.

Summary: Mathematical modeling is crucial in understanding radiobiology and designing treatment approaches in radiotherapy for cancer. This study compares three tumor volume dynamics models and analyzes the implications of model selection. A new metric, the point of maximum reduction of tumor volume (MRV), is introduced to quantify the impact of radiotherapy. The results emphasize the importance of caution in selecting models of response to radiotherapy due to the artifacts imposed by each model.
