Summary: Optimal timing for diapause induction through sexual reproduction of dormant propagules is expected in organisms with temporary populations, where genetic variation in propensity to produce dormant propagules may be maintained by a genotype-by-environment interaction in clonal reproductive rates. However, empirical studies do not support this hypothesis, suggesting that genetic variation in the timing of diapause may not be maintained by genetic differences in thermal clonal reproduction reaction norms.

Summary: In this study, 20-year-old Castanopsis hystrix experimental forests in Yulin, Liuzhou, and Pingxiang, Guangxi Province, China were used to assess the genetic variations and estimate the genetic parameters of growth and morphological traits. The average values for tree height, diameter at breast height (DBH), volume, height to live crown base (HCB), crown width (CW), and branch angle were determined. The block and family were found to be the most important sources of variance for growth and morphological traits, and the genotype x environment interaction effects were significant. Family heritability was also calculated for each trait. Excellent families with strong adaptability and genetic stability were identified using BLUP-GGE biplots. The results of this study provide a theoretical basis for efficient cultivation of C. hystrix in South China.

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: Genotype by environment interaction (G x E) is important in aquaculture species breeding, as selection in one environment may not have the same response in other environments. This study used a multiple trait reaction norm model to analyze the genetic relationship between growth traits of Nile tilapia in a (sub)tropical environment and found the presence of G x E. The genetic correlations may differ across different environments.

Summary: The use of plant-based proteins as a substitute for fishmeal and fish oil in aquaculture feeds has gained attention due to the high cost of nutrition. This study found that using a standard commercial diet instead of a plant-based one can achieve higher genetic gain, although it may reduce the genetic gain per generation. Therefore, establishing a breeding strategy based on plant-based diets is feasible but requires balancing the reduction in feed cost and the decrease in genetic gain.

Summary: Global food trade plays a crucial role in food security and availability. Research shows that there is a competitive relationship between efficiency and resilience in food trade networks when only network topology is considered, but a cooperative relationship exists when trade connection intensity is taken into account. This complex network framework can assist policymakers in evaluating the relationship between efficiency and resilience in critical supply chains.

Summary: Sustainable livestock production requires animals with high production potential and resilience to environmental challenges. This study used simulations of sheep populations to assess the effects of genomic data, genetic evaluation models, and phenotyping strategies on prediction accuracies and bias for production potential and resilience. The results showed that repeated measurements and genomic information greatly improved the estimation of both traits. However, the prediction accuracy for production potential was compromised and resilience estimates were biased when families were clustered in groups, even with genomic information. The study also demonstrated that genetic gains in both traits could be achieved across a range of environments, but simultaneous genetic improvement benefitted greatly from using genomic evaluation, reaction norm models, and phenotyping in diverse environments.

Summary: This study investigated the genetic and phenotypic background of energy reserves in Amur mirror carp and their impact on fish performance during the first winter. Results showed most traits related to energy reserves significantly decreased after the first winter, with differing genetic correlations and heritability before and after the winter. Interestingly, genetic correlations between HP glycogen traits and survival in the third growing season were positive, suggesting a genetically based strategy for energy mobilization in common carp. Monitoring FC and HSI could be useful for managing carp stocks.

Summary: This study investigated the relationships between off-flavor compounds, lipid contents, and fatty acids in rainbow trout reared in a recirculating aquaculture system (RAS). The results showed that fish with high lipid contents accumulated high concentrations of off-flavor compounds, but these compounds were negatively correlated with health-promoting fatty acids. Excessive lipid contents may reduce the nutritional value of the fish.
