Summary: This study examines the effects of rearing environment and relatedness on male aggression, harassment, and harm towards females in Drosophila melanogaster. Contrary to previous findings, the study reveals that unrelated-unfamiliar males are just as likely to fight and harass females as related-familiar males, and overall levels of male harm to females are similar across treatments.

Summary: Behavioral discrimination of kin is an important process in structuring social relationships in animals. This study provides evidence of discrimination towards non-kin through phenotype matching. In mandrills, mothers guide their offspring's social opportunities towards infants who resemble their own offspring. Results show that mothers are spatially closer to similar-looking infants, indicating adaptive maternal behavior.

Summary: Social animals, like ants, display a range of cooperative behaviors, including rescuing trapped group members. In this study, researchers investigated how ants prioritize rescues and whether they prioritize feeding over rescuing. They found that ants invested more time in rescuing pupae than adult workers and used different rescue behaviors based on the individual being rescued. Interestingly, ants recognized trapped individuals chemically rather than by appearance or behavior. However, foraging took precedence over rescuing, likely due to a smaller number of specialized rescue workers.

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: Negative relationships between the degree of parental investment and the presence of unrelated offspring in the nest due to extra-pair paternity (EPP) or conspecific brood parasitism (CBP) are predicted in monogamous species. This study examined the relationship between parental care and EPP or CBP in a semi-colonial Eurasian Tree Sparrow population. The results showed a negative relationship between male parental care and EPP, while CBP was linked to male parental investment.

Summary: It has been found that mothers in better physical condition tend to produce male offspring, while those in worse condition tend to produce female offspring. Competitive interactions within families and relative maternal condition both influence the offspring sex ratio, with no strong support for any single-factor model.

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: In monogamous birds, the maintenance of pair bond relies on previous breeding success and parental effort. Red-necked grebes, a long-lived species with parent-fed young, showed high pair fidelity regardless of recent breeding success. The study revealed that early brood abandonment by females may confer fitness benefits to males and reflect cooperation rather than conflict.

Summary: This study examined the association between parental cardiovascular health and the time to onset of cardiovascular disease in their offspring. It found that offspring of parents with ideal cardiovascular health had a greater CVD-free survival. Maternal cardiovascular health was a more accurate predictor of offspring's CVD-free survival than paternal cardiovascular health, emphasizing the importance of interventions involving mothers to break the intergenerational cycle of CVD-related morbidity and mortality.

Summary: Parent-offspring cannibalism is a common behavior in the animal kingdom, but the reasons behind this behavior are still not well understood. Factors such as parental energy reserves, brood sizes, parentage, and brood densities have been hypothesized to explain the occurrence of parent-offspring cannibalism. The behavior varies across different taxa and is thought to provide adaptive benefits to the cannibals. It also has the potential to generate conflict between sexes and there are still many aspects that require further research.

Summary: Studies on common tern populations have shown no clear signs of senescence in haemagglutination titre and haptoglobin concentration, possibly due to immune parameter canalisation or the colonial breeding behavior of the study species. Further longitudinal studies are needed to investigate the links between species characteristics and immunosenescence in wild animals.

Summary: This study investigated additive genetic variance in lifetime and annual fitness components in common terns. The results showed that the heritable variance in fitness of common terns is rather low, if not zero, and the estimates were associated with high uncertainty. The study highlights the importance of maintaining long-term individual-based studies of natural populations.

Summary: This study investigates the shared phenological responses to environmental drivers among different seabird populations. The results show that populations of different species sharing the same breeding site or small-scale breeding region have positively correlated laying dates, suggesting shared phenological responses to the same environmental conditions. However, no positive phenological covariation was found among populations across species at larger spatial scales. The study also highlights the idiosyncratic responses of populations to local environmental conditions.

Summary: Senescence, an age-related decline in survival and/or reproductive performance, occurs in various species. We explored the age-specific changes in DNA methylation in common terns, a relatively long-lived migratory seabird species known to undergo senescence. Our findings showed a decrease in autosomal methylation levels with age in females, but not in males, and no evidence of selective appearance/disappearance of birds based on their methylation level. These results lay the foundation for further investigations on the functional consequences of methylation patterns and their relationship to the ageing phenotype.

Summary: By analyzing the arrival dates of 1,715 individual common terns over a 27-year period, researchers found that their spring migration time had advanced by 9.3 days, with about 5% of the change attributed to advances in breeding values. Through estimation of genetic patterns, the study also found that the observed genetic changes were consistent with theoretical predictions. Overall, this study provides rare evidence for micro-evolution in the wild as an adaptive response to climate change, and illustrates how a combination of adaptive micro-evolution and phenotypic plasticity facilitated an earlier spring migration in common terns.

Summary: Sex-specific foraging behavior was observed in common terns, with females resting less and foraging closer to the colony in more coastal waters compared to males. Males showed higher variability in their foraging distribution throughout the tide cycle and foraged more outside of protected areas. This study highlights the importance of considering sex-specific foraging distributions when assessing the impact of at-sea threats on seabirds.
