Summary: Prestige-biased social learning occurs when individuals prefer to learn from prestigious group members. While previous research has confirmed the adaptive use of prestige-bias, the domain-specificity and generality of this bias has not been explicitly addressed experimentally.Results from an online experiment suggest that individuals overwhelmingly prefer domain-specific prestige cues, but also show a preference for domain-general cues when only cross-domain cues are available. This indicates that people may vary in the extent to which they employ domain-specific or domain-general prestige-bias depending on their experience and understanding of different domains.

Summary: Toxoplasma gondii infections in hyena cubs lead to them approaching lions more closely and experiencing higher rates of lion mortality, suggesting the possibility of parasite manipulation of host behavior for transmission to feline hosts. Both scenarios, where the behavior is an extended phenotype of the parasite or where the parasite has not undergone selection for behavior manipulation, have important implications for T. gondii's effects on host behavior and fitness in the wild.

Summary: Providing a natural diet is crucial for improving animal welfare and reducing stereotypic behaviors in captive slow lorises. Confiscated animals in rescue centers are often fed fruit and vegetables instead of their natural diet, which can compromise their welfare. By modifying their diet and using environmental enrichment devices, researchers were able to increase feeding and foraging behaviors while reducing stereotypic behaviors in these globally threatened primates.

Summary: Individual and prey traits play a significant role in shaping the dietary habits of the Savi's pipistrelle in agricultural ecosystems across the Mediterranean region. DNA metabarcoding identified 173 distinct prey taxa in bats sampled in Southern Italy, with agricultural pests dominating the diet. The study highlights the importance of understanding the functional relationships between individual bats and their prey for ecosystem services and the surveillance of relevant arthropod species.

Summary: This focused review introduces the ubiquity of dominance across the animal kingdom and the modern approach of measuring dominance using Percolation and Conductance (Perc). Perc takes into account the nonlinear hierarchical structure and provides a complementary metric of 'dominance certainty' to assess the degree of ambiguity in rank relationships. The review summarizes studies on the importance of 'dominance certainty' in large captive rhesus macaque breeding groups and concludes with suggestions for future research directions in dominance hierarchy.

Summary: A study on female common vampire bats revealed that their social rank was not influenced by body size, age, reproductive status, or kinship, grooming, and food sharing. Competitive interactions did not affect the social hierarchy among female vampire bats, possibly due to limited direct competition for food in the wild among frequently roosting females.

Summary: The study found that higher consumption of red meat was associated with an increased risk of frailty in older women, even after adjusting for lifestyle factors, medication use, and dietary factors. Each additional serving of red meat per day was associated with a relative risk of 1.13 for total red meat, 1.08 for unprocessed red meat, and 1.26 for processed red meat.

Summary: Variation in social status can impact gene regulation, glucocorticoid physiology, and mitochondrial DNA phenotypes in animals. Behavioral interactions associated with dominance rank play a significant role in these effects, often serving as better predictors of molecular and physiological outcomes than dominance rank itself.

Summary: This study investigated the effects of PEF processing and chilled storage on volatile composition and sensory properties of lamb cuts. PLSR was used to determine the relationships between volatile compounds, fatty acids, amino acids profiles, and sensory responses. The results showed that specific volatile compounds, fatty acids, and amino acids were correlated with meaty, juicy, livery, and browned flavors of PEF treated lamb cuts.

Summary: This study investigated the relationship between social behavior and parasite richness in a community of wild chimpanzees. The findings showed that individuals who spent more time with others in the same space had higher parasite richness, while grooming contact did not affect parasite richness. These results contribute to understanding the complex interplay between parasitism and sociality in group-living primates.

Summary: Individual participation in patrols varies based on several factors, rather than conforming to expectations from collective action theory. Sighting frequency, age, and hunting participation were the best predictors of patrol participation. Current and former alpha males did not participate at a higher rate than males that never achieved alpha status. These findings suggest that individual participation in group territorial behavior is influenced by multiple factors.

Summary: Through studying seven long-term continuous primate populations, we found that age has a significant impact on female reproductive performance and offspring survival in most species. This includes longer inter-birth intervals, reduced number of completed interbirth intervals, and lower survival rates among offspring born to older mothers. Maternal age also affects the age at which daughters first reproduce, particularly in species with female-biased dispersal.

Summary: Chimpanzees serve as reservoirs for malaria parasites, including those closely related to the most dangerous human malaria parasite. The age of onset and prevalence of malaria infection in chimpanzees vary seasonally, and temperature and forest cover are important factors affecting infection.

Summary: Populations on the edge of a species' distribution may be fragmented and geographically isolated, leading to lack of genetic exchanges and compromising adaptive potential. A study on chimpanzees in western Tanzania revealed two isolated populations, but with evidence of high gene flow within each cluster. The presence of barriers to gene flow, such as rivers and bare habitats, was confirmed by landscape genetic analyses. Advances in sequencing technologies and landscape genetics approaches can inform conservation efforts of endangered species.

Summary: To address the debate about human exceptionalism, this study examined the reproductive inequality of humans and their position among other mammalian species. The findings show that while humans exhibit lower reproductive skew among males and smaller sex differences compared to other mammals, they still fall within the mammalian range. The study also found that polygynous human populations have higher female reproductive skew compared to nonhuman mammals. These patterns of skew can be attributed to factors such as the prevalence of monogamy, limited degree of polygyny in human societies, and the importance of unequally held rival resources for women's fitness.

Summary: Personality traits in many taxa relate to fitness, but few studies have tested trade-off models in long-lived species. Using behavioral and genetic data from male chimpanzees, we found that Dominance and Conscientiousness traits were consistently associated with rank and reproductive success across the life course. These findings suggest that the trade-off model may not hold in long-lived species and highlight the validity of personality ratings in studying animal behavior.

Summary: This study investigated the gestation length and its impact on offspring survival in chimpanzees. The results showed that, similar to humans, chimpanzees had shorter gestations after short inter-gestational intervals (IGIs), and shorter gestations were associated with lower offspring survival.
