Summary: Scott et al. bring attention to species conservation by demonstrating heterozygote superiority among translocated tortoises, but their recommended decision rule may risk setbacks in conservation genomics. Further assessment and improvement are needed to guide conservation management effectively.

Summary: Recently, populations with very low genetic diversity have been found, some of which can persist in the long term, while others may face extinction. This study focuses on the Iberian desman population, which exhibits extremely low heterozygosity values and high levels of inbreeding. Some individuals in the population appear to be genetically identical, posing challenges for genetic identification and parentage analysis. However, characterizing these genetically impoverished populations and improving genomic methodologies for their study are crucial for scientific and conservation purposes.

Summary: The use of genomic data allows for more accurate assessment of inbreeding level and depression. Genome-based inbreeding coefficients show stronger correlations with pedigree-based inbreeding coefficients, particularly those based on runs of homozygosity (ROH) segments and heterozygosity by descent segments (HBD). Genome-based inbreeding coefficients have more significant effects on reproductive traits compared to pedigree-based inbreeding coefficients.

Summary: The European red mite has successfully invaded new habitats by overcoming barriers such as inbreeding depression and adjusting resource allocations for reproduction, leading to its invasion success in successive generations.

Summary: The study on cassava breeding analyzed various factors affecting flower abortion and proposed strategies to overcome them, providing new insights and methods for efficient breeding. Through experiments and analysis, reproductive barriers and pollen-pistil interactions were studied, leading to the identification of population structure of elite parental clones. Significant parental effects were identified, indicating the existence of reproductive barriers among certain cassava clones, and non-additive genetic effects played a role in trait inheritance. Pollen viability and pollen-stigma interactions were found to be significant for successful fertilization, with variations in pollen viability and stigma receptivity depending on clone and flowering stage.

Summary: Across the animal kingdom, little is known about the development of social environments, particularly in wild populations. This study examines how associations among young animals form and are influenced by environmental or genetic conditions established by parents. The results suggest that the natal environment created by parents, rather than genetic condition, establishes the foundation for social associations in offspring.

Summary: This study examines sexual selection and mating preferences in the campo flicker, finding assortative mating for neck and throat coloration. Additionally, individuals with larger crowns and a lighter yellow neck coloration were more likely to reproduce. These findings have important implications for understanding the mechanisms of sexual selection and population genetics in cooperative breeders.

Summary: Reproductive success and offspring survival of fish are important for fish fitness and aquaculture development. The variance in offspring survival and its impact on genetic diversity were studied in rainbow trout. The results showed unbalanced dam contributions to survival at different stages and low heritability of early survival traits, with maternal effects playing a larger role. Phenotypically, offspring early survival was correlated with dam fecundity and dam post-spawning weight. Promoting high fecund females could help improve offspring early survival and maintain genetic diversity in breeding programs.

Summary: The Chinese Crested Tern is one of the most endangered seabird species in the world, with lower genetic diversity and signals of post-bottleneck population expansion observed. The study also found introgression between Chinese Crested Tern and Great Crested Tern.

Summary: The study revealed similar levels of genetic diversity between cultured and wild fish populations. Global genetic differentiation was low, indicating that genetic variation mainly occurred within populations. However, a reduced contemporary effective population size was observed in farmed fish populations, possibly reflecting a bottleneck caused by founder effect.

Summary: This study conducted in Belgium found that populations of Juniperus communis have high genetic diversity, low to moderate genetic differentiation, and no clear geographic structure. The populations showed predominantly sexual reproduction, with no clonality observed. High positive inbreeding coefficients were explained by null alleles, population substructuring, and biparental inbreeding. Patterns indicated historical gene flow through pollen and seed dispersal at both short and long distances.

Summary: The outcrossing species C. remanei can recover from inbreeding, but the recovery is limited by the presence of a large number of segregating deleterious variants in natural populations.

Summary: The study found that Sonneratia griffithii is suffering from inbreeding depression and is dependent on pollinators, particularly bats, for reproduction. Recommendations include protecting pollinators and creating corridors between mangrove forest patches to protect this endangered species.

Summary: The goal of genetic selection is to improve genetic progress, but it can lead to inbreeding and accumulation of harmful alleles, reducing genetic diversity. The study on Mexican Romosinuano cattle revealed a decreased effective population size, genetic bottlenecks, and declining genetic diversity as potential challenges.

Summary: The study analyzed the genetic parameters for reproductive traits in mares of the PRE horse breed and estimated, for the first time, the inbreeding depression load associated with common ancestors of the breed. The results showed significant correlations between additive genetic values and inbreeding depression load, indicating the potential to select horses with genetic value resistant to the deleterious effects of inbreeding.
