Summary: Sexual selection plays a crucial role in the evolution of phenotypic traits and patterns of biodiversity. This study investigates the link between resource acquisition and sexual selection on mate-acquisition traits, providing testable predictions. The findings suggest that selection on mate-acquisition traits is influenced by various factors such as the stage of selection, the association between resource and mate acquisition traits, and the proportion of males with these traits.

Summary: Hamilton's theory of local mate competition explains female-biased sex ratios in various organisms, but in some wasp species, the bias is more extreme than predicted. Research shows that cooperation between related females can result in even more female-biased sex ratios, especially when cooperation occurs between mothers and offspring before dispersal. This suggests that additional factors, such as cooperative interactions, play a role in determining sex ratio biases in certain species.

Summary: Melittobia australica females exhibit a sophisticated sex ratio behavior, producing consistently female-biased offspring sex ratios when they have not dispersed and adjusting their sex ratio based on the number of females laying eggs when they have dispersed. This indicates that dispersal status serves as an indirect cue for relatedness and influences their sex ratio adjustments.

Summary: The study investigated the dispersal dynamics of the endangered Crested Ibis population in China. Natal dispersal was found to be common, while breeding dispersal was rare. Density-dependent effects and intraspecific competition played a role in the expansion of the population. Conservation efforts should focus on identifying and protecting potential reintroduction areas for the Crested Ibis to settle in low-density breeding areas.

Summary: We investigated the properties and qualities of both ancient and alternative Kriab mirrors, finding that the alternative mirrors have potential in heritage conservation and restoration work. Due to this, Thai professional conservators have embraced their use in restoration projects. However, the weathering durability of the alternative mirrors is poor, highlighting the need for further development of mirrors with similar properties or even more environmentally friendly alternatives.

Summary: The study reveals that German creative writers in the 18th and 19th centuries had a long-term trend of movement, initially to small university towns and later to larger cities like Berlin and Munich. Migration and yearly publication output were strongly linked to age. These relationships followed similar patterns across different subperiods.

Summary: Our investigations at the Sotomeyachi site in Japan revealed three sandy event deposits, with E2 and E3 likely corresponding to historical tsunamis caused by earthquakes, while E1 is unlikely to be a tsunami deposit.

Summary: This research investigates the effect of weaning after similar to 6 months of age on cholera mortality among 18th-19th-century Italian populations. The results show that age-at-weaning completion was not a predisposing factor in cholera mortality in adulthood, possibly because weaning completion likely occurred after infants had adapted to consuming contaminated weanling foods.

Summary: This study examines the effects of resource restriction on pre- and post-copulatory traits in male pygmy halfbeaks. The results show that resource restriction leads to reduced body size, beak size, courtship behavior, and testes size, but unexpectedly, the restricted-diet group had a larger area of red color on the beak and fins after the diet treatment.

Summary: The study demonstrates that physiological costs of intrasexual competition in male spotted hyenas vary with social rank, shaping behavioral trade-offs between social integration, reproduction, and self-maintenance. This suggests that physiological and social constraints play a key role in the emergence of rank-related male reproductive success.

Summary: This study examines the juvenile dispersal of the poorly studied Black-shouldered Kite in southwestern Spain and provides evidence supporting the Resources Competition Hypothesis. The study also analyzes the dispersal distance of the juveniles and provides crucial demographic parameters for future conservation plans.

Summary: The external geometry of the human femur changes significantly during early ontogeny, corresponding to key stages of childhood locomotor development. The Metaphyseal bicondylar angle (BCA) increases throughout growth, especially between 1 to 2 years when children begin to walk, while the neck-shaft angle (NSA) increases in the first few months after birth, then rapidly declines around 7 months and steadily decreases during the second year as children learn to walk.

Summary: This article explores the marriage payments in late Ottoman Greece, focusing on the payment called "egenliki" made by a bride entering a second marriage to a groom who has never been married before, and the rarer payment made by the groom to the bride for her virginity. By examining dowry contracts and tracing the historical trajectory of such payments, the article argues that these rare payments were symbolic, aiming to address perceived inequality in marriage and prevent societal disapproval of marriages where only one member had been previously married.

Summary: Bocage and other contemporary poets in Portugal faced censorship during their time, leading to the clandestine circulation and delayed publication of their works until the 19th century. However, the interest sparked by these texts among 19th-century poets and editors eventually led to the emergence of some works. This article argues that the integration of the Portuguese libertine tradition of the 18th century into the literary canon is a result of the triumph of Liberalism and its impact on literary and editorial dynamics.
