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 article proposes an alternative formulation of quantitative genetics based on information theory, which provides sensitive and unbiased measures of statistical dependencies among variables. This new theoretical framework offers a novel approach for studying genetic interactions and relationships.

Summary: The Ziziphus jujuba var. spinosa has a strong breeding system adaptation, relies on pollinators, and has a low fruit setting rate that is not influenced by self-pollination.

Summary: Conservation genetics aims to evaluate population health and extinction risk based on genetic diversity levels, but neutral genetic diversity is not the only factor affecting species extinction risk. A deeper understanding of functional genetic diversity, demographic history, and ecological relationships is necessary for developing effective conservation genetic strategies.

Summary: During epidemics of a virulent bacterial pathogen, the proportion of resistant phenotypes in a natural host population increased significantly due to selection from the local parasite. A genetic model was built through genome-wide association study, identifying two genomic regions controlling resistance polymorphism in the host with dominance and epistasis. The findings underscore the importance of epistatic effects in host-parasite coevolution, particularly in the Red Queen model for the evolution of genetic recombination.

Summary: Inbreeding can cause bias in estimating quantitative genetic parameters, affecting the selection response in species with both hermaphroditism and self-fertilization. This study assessed the biases caused by self-fertilization on heritability estimates for productive traits in the tropical hermaphrodite pectinid Argopecten nucleus. The study found that self-fertilization resulted in inbreeding depression and an overestimation of h2 for productive traits, but did not affect estimates of genetic correlations or genotype-environment interactions.

Summary: Adaptive coevolution of Y- and mitochondrial genes in male fertility is hindered by their uniparental inheritance, but potentially counteracted through compensatory evolution of gene mutations, especially in inbred populations where positive effects on male fertility exist in Y-mt gene combinations.

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: Rapid environmental change poses a significant challenge to natural populations, and evolutionary rescue can prevent extinction by enabling rapid adaptation. This study found that the demographic history of populations plays a crucial role in evolutionary rescue. Populations without a history of bottleneck avoided extinction entirely, whereas more than 20% of populations with an intermediate or strong bottleneck went extinct. These results emphasize the importance of considering population history when making conservation decisions and management strategies to address environmental change.

Summary: Most flowering plants rely on animal pollination, but the effects of different pollinators on plant fitness have not been fully understood. This study shows that non-native honeybees tend to visit more flowers on individual plants compared to native insect visitors, resulting in increased self-pollination. Offspring produced after honeybee pollination have similar fitness to those resulting from hand self-pollination but are less fit than those produced after pollination by native insects or cross-pollination. This study is the first to directly compare the fitness of offspring resulting from honeybee pollination with that of other floral visitors.

Summary: This study analyzed genomic data of three isolated populations of Brown eared pheasant in China, showing low genome-wide diversity and declining effective population size. The comparison with a closely related species revealed detrimental genetic consequences in the Brown eared pheasant genomes, indicating a potential risk of deleterious mutations in wild populations undergoing long-term decline. This comprehensive conservation genomic analysis could help improve conservation planning for threatened species and promote population recovery.

Summary: Androdioecy, the coexistence of hermaphrodites and males, is rare in vertebrates, but occurs in mangrove killifish. The advantages of outcrossing-oriented hermaphrodites and the production of males strongly affect each other. Different models are studied to explain the discrepancy between the predicted high male fraction and the observed low male fraction.

Summary: We studied the spatial patterns of kinship in the offspring of the endangered Lodoicea maldivica. Our findings suggest that restricted seed and pollen dispersal in populations have led to a strong spatial genetic structure. The study also revealed that mother trees were often pollinated by multiple fathers, and parental pairs were more closely related than expected by chance, indicating a preference for close kin in mate choice.

Summary: This study investigated the relationship between genetic variation and population dynamics in Boechera fecunda. The results showed a weak positive correlation between genetic diversity and demographic performance. The inbreeding coefficient was not strongly correlated with demographic performance. Conservation of distinct B. fecunda populations is recommended.

Summary: Seed banking is a common strategy that reduces genetic drift and population overlap. However, its impact is often ignored in the detection of selective sweeps. By simulating weak seed banks, we found that seed banking does not affect fixation probability but increases fixation time and alters genomic signatures of selection.

Summary: Seed banking is a widespread bet-hedging strategy that decreases the magnitude of genetic drift and changes the genomic signatures of selection. By integrating simulation programs with seed banking, footprints of selection can be predicted and past evolutionary events can be inferred.
