Summary: Sexual prejudice refers to negative attitudes towards individuals based on their sexual orientation. The study found that social dominance orientation, femininity (among females), and masculinity (among males) are positively related to prejudiced attitudes toward gay men and lesbians. It was also discovered that social dominance orientation interacts with femininity, but not with masculinity, in predicting sexual prejudice.

Summary: This study aimed to explore how the social environment influences the spring migration traits of male yellow-rumped warblers. The results showed that sex ratio did not affect body mass or molt progression, but males in the male-biased treatment exhibited significantly less locomotor movement. These findings suggest that the social environment can impact the behavior of songbirds, but do not support the hypothesis that a male-biased sex ratio accelerates migration.

Summary: This study examines intersexual power dynamics in primates and finds that while male-biased power is most common, there are societies without such bias. Factors such as differing fighting ability and mating opportunities contribute to power imbalances. Male-biased power is associated with males being larger and more females in social groups, while non-male-biased power is associated with a higher demand for mating opportunities with females. Non-male-biased power has evolved independently multiple times in primates.

Summary: This study examines the relationship between social factors (perceived social injustice and social dominance orientation) and the likelihood of cyberbullying. Online experiments with adult samples from the USA and China tested the impact of these factors on cyberbullying likelihood using hypothetical social injustice scenarios in the workplace. The results show that perceived distributive injustice positively predicts cyberbullying likelihood, while social dominance orientation negatively predicts perceived social injustice and positively predicts cyberbullying likelihood. There was only one significant difference between the USA and Chinese samples. These findings suggest that social factors can influence cyberbullying dynamics across different nationalities.

Summary: The people and leaders of Africa have always viewed education as a catalyst for development and freedom. This view is supported by international institutions, as education provides significant economic and non-economic benefits, especially in low-income areas. This study examines the educational progress across different religious groups in postcolonial Africa, with a focus on Christian and Muslim communities. The findings show that Christians have better educational outcomes compared to Traditionalists and Muslims, even among households with similar economic and family backgrounds. Furthermore, Muslims have lower internal mobility, residing in less urbanized and remote areas with limited infrastructure, which contributes to the educational gap between Christians and Muslims.

Summary: This study examines parents' preference for school segregation and its association with social dominance orientation, intergroup contacts, belief in traditional schooling, and the absence of Roma children in school. The results suggest that ethnically motivated school withdrawal is a result of individual attitudes and situational factors.

Summary: Research on vespertilionid bats revealed that males and non-breeding females are often segregated from large maternity groups, while breeding females are separated from non-breeding females and males during the lactation period. Factors such as group size, female reproductive condition, and time period were found to be key factors associated with sexual segregation within bat roosts. This study contributes valuable insights into inter- and intra-sexual segregation in vespertilionid bats and suggests that sexual size dimorphism is not a prerequisite for sexual segregation.

Summary: Sexual dimorphism is widely believed to be an adaptive trait, with males and females evolving towards different fitness optima. Evolution of sexual size dimorphism, shape dimorphism, and their allometric relationship were investigated in 82 taxa in the family Drosophilidae, showing remarkable similarities in shape dimorphism among species and quantitative variation in both size and shape dimorphism. The evolution of dimorphism was constrained by allometry for some traits, but was evolutionarily labile in others, suggesting different evolutionary optima among species over millions of years.

Summary: In many species, sexual dimorphism increases with body size when males are the larger sex but decreases when females are the larger sex, a macro-evolutionary pattern known as Rensch's rule. In this study, it was found that males were slightly smaller than females and body size did not follow Rensch's rule, whereas the length of the fourth pair of legs in males followed Rensch's rule. It is suggested that sexual selection might be stronger on the length of the fourth pair of legs than on body size in males, and the potential role of condition dependence in the emergence of Rensch's rule is discussed.

Summary: This article examines the social forces that limit migration, focusing on internal migration in the United States. By proposing a systemic, network model of migration flows, the study reveals the pattern of segmented immobility, where fewer people migrate between counties with dissimilar political contexts, levels of urbanization, and racial compositions. The findings suggest that approximately 27% more intercounty migrants could be observed if the segmented immobility mechanisms were not in place.

Summary: The study found that lesser black-backed gulls exhibit consistent individual strategies for non-breeding distributions, winter site fidelity, migration routes, and timing of migration, regardless of migration distance. However, there are still individual differences in behavior, and these differences are not related to migration distance. This suggests that individuals have the capacity to adjust to current conditions within their individual strategies, and occasionally even change their strategy.

Summary: Non-frugivorous waterbirds play a crucial role in dispersing weed plants over long distances, exchanging species between human-dominated and natural areas. The study demonstrates that about 92% of weed seeds are dispersed within the birds' activity area, while the remaining 8% reach other habitats, with 42% reaching moist environments suitable for weed establishment. This research emphasizes the significance of non-frugivorous birds in long-distance plant dispersal, an often overlooked mechanism in weed plant expansion studies.

Summary: Individual niche variation is common within animal populations and may temporally vary due to behavioural plasticity. This study found that breeding female lesser black-backed gulls showed pronounced shifts in habitat use and almost disappeared individual variation in foraging behavior during the breeding season, which suggests a complex interplay between competitive constraints, resource reliability, and shifting time- and energy budges in shaping temporal dynamics in individual niche variation.

Summary: This study found that Daphnia spp. are effective at removing Bd zoospores, while high concentrations of the algae P. subcapitata may interfere with pathogen removal rates. It suggests potential management actions for biological disease mitigation, with the goal of optimizing conditions for filter feeders like Daphnia to reduce pathogen densities and infection pressure in amphibian hosts. Additional field trials are needed to further confirm these findings and evaluate the impact of intervention actions.

Summary: The nutrient composition in the diet of brown bears has metabolic significance and is related to their foraging behavior. The study found that brown bears have a diet dominated by vertebrates and ants in spring and early summer, and berries in fall, resulting in protein-rich and carbohydrate-rich diets, respectively. Although there were differences in dietary ingredient proportions between reproductive classes, the nutrient concentrations in the diet were similar, indicating that bears are able to maintain a consistent nutrient profile by selecting different ingredients. The study also showed that the bears' diets provided sufficient glucogenic substrate for efficient metabolism throughout the year, suggesting either a driving force of metabolic efficiency in diet selection or abundant natural resources available to the bears.
