Summary: This article discusses the importance of kinship dynamics and their impact on social behavior and life history evolution, highlighting new insights brought by the kinship dynamics approach in behavior and life history evolution, and exploring new research directions that analyzing kinship dynamics could provide.

Summary: Sociality is common among animals, but intergroup cooperation is rare. This study explores the reasons for its rarity and the conditions that promote its evolution. The researchers find that dispersal modes play a crucial role in intergroup interactions, and that localized dispersal is more likely to lead to the evolution of intergroup aggression, tolerance, or even altruism. However, the evolution of intergroup cooperation may have ecological impacts that affect its own evolution. The study also discusses empirical evidence of intergroup cooperation in ants and primates.

Summary: Helping strangers at a cost is difficult to justify from the perspective of natural selection, but reputational scoring and mutual consent can enable cooperation without oversight. The most successful strategy resembles token exchange in money transactions but is not physically realizable in a decentralized way. When conservation of score is enforced, more money-like strategies dominate.

Summary: Social behaviors often rely on kin recognition, and recent research suggests that altering host-associated microorganisms may provide insights into the mechanisms of kin recognition. This study investigates the effects of larval rearing environment and relatedness on gut microbiota and cuticular hydrocarbons in the fruit fly Drosophila melanogaster. The results show that rearing environment strongly influences microbiota composition and hydrocarbon profiles, while relatedness mainly affects microbiota diversity, which in turn covaries with hydrocarbon profiles.

Summary: This study investigated conflict initiation and participation in groups, finding that small group size, low migration rate, and frequent interaction between groups increased intergroup competition and the evolution of "exploitative" leadership. Conversely, patterns favoring increased intragroup competition led to the emergence of "heroic" leaders. An alternative leader/follower "shared effort" outcome was also observed.

Summary: By averaging the payoff values of neighbors, ambiguity can be avoided and cooperation level can be improved. The positive impact can be strengthened by increasing the role of the environment and the size of the evaluation circle in the self-organizing process.

Summary: This paper uses spatial evolutionary game theory to model the social dilemma of involution on a square lattice. The study investigates the impact of the abundance of social resources, the social temperature in resource distribution, and the cost of more effort on involution. The results show that more abundant social resources lead to the involution, an increase in social temperature in resource distribution suppresses the involution, and an increase in the cost of more effort does not always aggravate or suppress the involution.

Summary: This paper extends the classical Banzhaf index of power to voting games with players who have weights representing different cooperation or bargaining abilities. The obtained value does not satisfy the classical total power property, but is monotonic in the weights. Three different characterizations of the value are obtained, and it is related to the Owen multilinear extension.

Summary: This study compares public goods game (PGG) and reversed public goods game (R-PGG) and finds that they are equivalent in some cases but behave differently in others. Heterogeneous parameters impede cooperation in R-PGG but promote it in PGG.

Summary: In public goods games, rewards have been shown to be an effective mechanism for sustaining cooperation. However, pure cooperators become second-order free-riders because they are not willing to bear additional costs. To address this issue, introducing a tax mechanism can effectively incentivize cooperation.

Summary: This study analyzes the replicator dynamics of tax-based punishment in the public goods game and finds that the combination of taxation and punishment can stabilize cooperation. Interestingly, tax-based punishment and tax-based pure reward can stabilize the same level of cooperation with the same conditions despite their opposite mechanisms.

Summary: Evolutionary game theory is an interdisciplinary subject that extends beyond biology, attracting mathematicians, social scientists, and computer scientists. The field has the potential for convergence or continued cross-fertilization between different disciplines, as insights are discovered and applied in various fields. The popularity of evolutionary game theory lies in its explanatory power and intuitive models.

Summary: Human-automation conflict is a frontier subject that needs to be vigilant against, especially under cyberattacks. This study transforms common attacks into understandable representations and explores the conflict under five generalized attacks using game theory. The results show that cyberattacks can significantly cause conflicts, and the control actions can buffer the impact of attacks within a limited range. The conflict risk can be used to distinguish faults and attacks, and appropriate measures can be taken accordingly.

Summary: In ant societies, multiple queens may compete over reproduction. The study shows that in Formica fusca ants, queens adjust their egg laying rate based on the kinship of their nestmates. When exposed to odor of a highly fecund non-kin queen, queens increase their egg laying rate, while if the queen is a close relative, queens decrease their egg laying rate to reduce competition. This demonstrates that cooperative breeding behaviors in Formica fusca queens are influenced by kinship and fecundity of others.

Summary: Individual and societal reactions to a pandemic can create social dilemmas. The extent of regulations to reduce transmission is small in most countries, resulting in interventions driven by individual decision-making. We propose a framework to quantify this situation based on protection, infection risk, and intervention costs, and discuss the tension between individual and societal benefits.
