Summary: The prenatal environment can affect the performance of cattle. The offspring of cows in a better gestation environment show better productive and reproductive performances. Genetic merit can vary depending on the gestational environment. Genomic regions that affect economic traits in cattle were identified. Breeders should consider the genotype by prenatal environment interaction and provide proper care for pregnant cows.

Summary: This study investigated the QTL-by-QTL, QTL-by-environment, and QTL-by-QTL-by-environment interactions by targeting four loci controlling grain length in rice. Through the development of near-isogenic lines with different genetic combinations and the analysis using linear models and interaction principal component analysis, the variations of additive effects, QQ effects, and environmental effects were estimated. The results showed differential responses of QQ effects to different environments, as well as differences between QQ effects including the long-grain allele at LKF and those excluding this allele.

Summary: Long-term evolution experiments have demonstrated the importance of genetic and environmental factors in influencing evolutionary outcomes. This study tracked the evolution of four strains of E. coli bacteria for 2000 generations in different environments. The results suggest that both deep and shallow phylogenetic histories play a significant role in evolved fitness, but their effects vary in different selection environments.

Summary: Edge computing offers lower end-to-end latency and enables real-time, latency-sensitive applications to be deployed on servers closer to end-users. This article focuses on the cost-effectiveness of user allocation solutions, aiming to maximize the number of users allocated to edge servers and minimize the required number of servers to reduce operating costs. A heuristic approach is proposed to efficiently find sub-optimal solutions to large-scale user allocation problems.

Summary: The study found that the critical periods in which heifer reproductive performance is more sensitive to heat stress vary depending on the trait, highlighting the need for detailed analysis to determine the appropriate period for other fertility traits. Significant GxE effects were detected for all three traits, emphasizing the importance of considering GxE in dairy cattle breeding schemes. Additionally, candidate genes identified through genome-wide association studies provide insights into selecting heat-tolerant animals with high reproductive efficiency.

Summary: This simulation-based study assessed the impact of linkage disequilibrium (LD) and epistasis on Hayman's diallel and generation mean analysis. The results showed that under low LD and no epistasis, the diallel analysis provided confident results about the inheritance of the quantitative trait, but had biased estimates of the dominance components and genetic parameters. High LD under no epistasis led to the rejection of the additive-dominance model.

Summary: This article studies the mutual effect of environment and resources allocation on cooperation using a spatial multigame model. It redefines the fitness of individuals in the multigame by incorporating environmental factors and limited resources. The relationship between resource quantity and strategy selection is analyzed, along with the evolutionary dynamics of cooperation clusters and the impact of resources on the multigame system's evolution behaviors.

Summary: The emergence of sixth-generation wireless communication technology has led to the rapid increase of real-time applications. Edge computing driven by Cybertwin is proposed as a promising solution to meet user demand, but it comes with challenges. This work proposes a joint resource allocation and computation offloading scheme using deep reinforcement learning in Cybertwin-enabled 6G wireless networks. The results show that the proposed scheme can reduce latency and energy consumption while improving task completion rate compared to traditional methods.

Summary: Temperature plays a key role in shaping organisms, particularly ectotherms. The study on European grayling embryos revealed differences in genome-wide methylation patterns and genetic polymorphisms among populations from different thermal origins. The findings support the significant role of epigenetic mechanisms in modulating plastic responses to environmental changes.

Summary: This study constructed a transcriptome for Atlantic salmon whole blood using RNA-seq and identified transcriptomic proxies for the major maturation timing gene vgll3. Differentially expressed genes related to early and late maturing genotypes were associated with ribosomal subunit genes. Comparing the blood transcriptome to reference transcriptomes of other tissues, it was found that the blood transcriptome was unique compared to other tissues' transcription profiles.

Summary: The study introduces a new analytical framework for quantifying ongoing natural selection at the transcriptome level in wild vertebrates. By integrating mark-recapture field sampling and RNA-sequencing with regression-based selection analysis, the study estimated selection on transcript abundance in wild salmonid fish affected by an extracellular parasite. The results reveal upregulation of mitotic cell cycle process in infected hosts and disruptive selection signals on transcripts related to host immune defense, host-pathogen interactions, cellular repair, and maintenance.

Summary: The fishery for Northern Atlantic cod off Newfoundland and Labrador witnessed a dramatic decline from sustainable fishing to collapsed stock due to industrial trawl fishing under a seemingly sophisticated management regime. Research suggests that if fishing effort and mortality had been stabilized in the 1980s, precautionary annual yields could have been sustained, highlighting the importance of incorporating prior knowledge to inform sustainable management practices.

Summary: The study found that the trends in marine survival varied among different populations of Atlantic salmon, with the changes in marine survival primarily affecting the returning numbers after one year for the fish. However, other factors also played a role in the variations in return abundances among populations.

Summary: In this study, the role of developmental stage in resistance and tolerance in Atlantic salmon was investigated. The results showed that developmental transition is associated with reduced resistance but does not affect tolerance. Additionally, it was observed that tolerance slopes can be largely independent of infection. These findings suggest that the relative importance of different defense types may vary with host development.

Summary: Research shows that there are differences in activity expression among Atlantic salmon life-history genotypes. The vgll3*E allele is associated with increased activity in females, while the vgll3*L allele is associated with increased activity in males. These sex-dependent effects may contribute to maintaining genetic life-history variation within populations.

Summary: The environment, including temperature and diet, affects reproductive traits in female fish. In this study, the effect of temperature and diet on maturation and egg traits in Atlantic salmon was investigated. A temperature difference of 2 degrees Celsius delayed maturation in female salmon, while a reduction in dietary energy content had no effect. Diet did not impact body size, condition, fecundity, egg size, or protein content, but a higher energy diet increased egg lipid content. These findings suggest that the nutritional quality of the female's diet can impact the energy provisioning of eggs and potentially affect the fitness of offspring.

Summary: Sexual dimorphism may evolve under antagonistic selection, where different optimal traits for the sexes are favored. Sexual-size dimorphism (SSD) is often assumed to indicate the resolution of sexual conflict, but the decoupling of trait architecture between sexes remains largely unknown. We tested the architecture of body size in the African hermit spider and found that the genetic and maternal effects on body size differed between sexes, suggesting a sex-specific architecture that allows for independent body-size evolution.
