Summary: This study proposes a new genetic similarity index based on genetic marker loci, which focuses on shared heterozygosity and improves the ability to distinguish sample pairs belonging to different clones. The method successfully detects clonemates in a location dominated by a single clone and can also be used to detect parent-descendant pairs under selfing.

Summary: This study investigates the reproductive responses of Stipa breviflora to warming and increased precipitation. The results showed that increased precipitation benefits sexual reproduction, while the effects of warming on reproductive and vegetative ramets vary depending on precipitation conditions. The findings suggest that there is no trade-off between sexual and clonal reproduction in S. breviflora.

Summary: This study investigates the genet dynamics and variability among neighbouring genets in Convallaria keiskei based on the ramet demography data. The study finds that the variation in genet dynamics is primarily caused by differences in clonal growth rather than survival-transitions between ramet size classes. The study also highlights the importance of clonal growth frequencies and connecting patterns of ramets in determining genet dynamics.

Summary: The costs of immune response can lead to trade-offs with other physiological functions such as reproduction, and these trade-offs are influenced by environmental variability. Higher environmental variability results in increased investment in the immune system at the cost of decreased reproduction, showing that optimal strategies are contingent on environmental conditions. This has implications for various aspects of infectious disease dynamics and evolution.

Summary: The fall armyworm has invaded large parts of Africa and Asia since 2016, impacting millions of hectares of maize crops and posing a major threat to food security. Limited research has been conducted on the physiological determinants of their flight and migration abilities. This study found that mating and oviposition affects the flight ability of S. frugiperda females, with a possible trade-off between flight and reproduction.

Summary: The leaky expression of male and female reproductive traits in Mercurialis annua is enhanced in response to simulated herbivory, resulting in increased probability and degree of leakiness in both sexes. The leakiness is more prominent in larger females, but not in larger males.

Summary: Animals regulate their food intake to maximize fitness traits, but they must trade off optimal expression of some traits due to differences in nutrient requirements. Previous methods to measure nutritional trade-offs were subjective, conceptually difficult, computationally expensive, and sometimes inaccurate. This study presents a simple trigonometric model, nutrigonometry, to measure nutritional trade-offs in multidimensional landscapes, which is easier to understand and use than previous approaches. The results show that polynomial (Bayesian) regressions can accurately predict peaks and valleys in performance landscapes, irrespective of data structure. Nutrigonometry enables fast, reliable, and reproducible quantification of nutritional trade-offs, broadening the potential for evolutionary nutrition research.

Summary: Exposure to low maternal investment is associated with trade-offs between life history functions in sons, helping to explain the clustering of adverse outcomes. The results indicate that reduced maternal investment is associated with early reproduction but less investment in growth, education, or healthy behavior.

Summary: The aim of this study was to examine the role of temperature in latitudinal patterns of egg size and maternal investment trade-offs in coral taxa. A comprehensive global dataset was compiled, and Bayesian phylogenetic multilevel models were used to analyze the data. The results showed a significant relationship between coral egg size and symbiont transmission, but no significant relationship with sea surface temperature and fecundity for broadcast spawning corals. The findings have important implications for understanding population maintenance and connectivity in corals.

Summary: A study in Belgium restricted watering of Frangula alnus Mill. potted cuttings, leading to reduced total berry count across different provenances. The different origins of the plants also showed slight differences in average stone count and weight of the berries.

Summary: In the study of a female-only parthenogenetic lizard, clutch size and body size were found to be key factors influencing follicle size, with investments in larger clutches and follicles associated with increased oxidative damage. The relationship between follicle size and clutch size was not linear, and factors like oxidative stress played a role in explaining variability in this relationship.

Summary: This study highlights the potential trade-offs between growth, defense, and reproduction in plants, especially uncovering potential induced defenses in the invasive wineberry. The results also indicate significant trade-offs between reproduction and growth, reproduction and defense, and defense and growth in both native blackberry and invasive wineberry species.

Summary: This paper estimates the dimensional and dynamic trade effects of monetary integration in the African Franc Zone. The results show heterogeneous effects, with both dimensional and time-related effects. While the average effect of monetary integration is positive and significant, different countries experience different effects and the time-related effects are not uniform. However, when considering the Franc Zone as a consolidated entity, absolute trade losses disappear. Furthermore, economies of scale are found for low trade intensities. Based on these findings, a set of policies is proposed to implement resilience mechanisms and reform the monetary structure of the Franc Zone.

Summary: This study found that severely infected ant males have a lower fighting success rate compared to mildly infected males. Males with a strong immune response are more likely to die during combat shortly after pathogen exposure, indicating a trade-off between immune investment and competitive ability. Additionally, worker aggression towards infected males further contributes to their failure in male-male competition. The study reveals a novel social immunity mechanism employed by social insect workers to protect the colony against disease risk.

Summary: Polyploidy is a major driver of evolutionary change in plants, and urban landscapes provide a unique opportunity to study polyploidy in action. By integrating polyploid biology and urban evolutionary ecology, researchers can predict and understand the ecological and evolutionary processes of polyploid plants in urban environments.

Summary: Polyploidy plays a significant role in the evolution of many taxa, but the factors influencing polyploid establishment in natural populations are often unclear. Our study shows that a perennial life history and clonal propagation facilitate the early stages of polyploid establishment and persistence.
