Summary: Genetic diversity within species is essential for population and ecosystem persistence and integrity, influenced significantly by factors such as population size and connectivity. This study highlights the importance of historic bottlenecks, contemporary colony size, and connectivity in shaping genetic diversity, with contemporary connectivity having the most profound impact at a large geographic scale. Understanding the relative importance of these factors over time is crucial for effective conservation planning.

Summary: Despite population recovery, the Channel Island fox has experienced a decrease in genetic diversity, and genetic divergence between populations has increased over time. This poses challenges for species conservation, as certain subspecies are having difficulties in recovering genetic variation.

Summary: This study investigated the genetic diversity and inbreeding situation of Saanen x Beetal goats. The results showed a high level of inbreeding in the reference population, with only a few ancestors contributing to the genetic diversity. Inbreeding had non-significant effects on reproductive traits, except for age at first service and age at first kidding. To reduce inbreeding and increase genetic diversity, a stratified breeding plan and the introduction of unrelated crosses should be followed.

Summary: The critically endangered Rhododendron meddianum exhibits high genetic diversity among populations, moderate genetic differentiation, and clustering into three distinct genetic groups. A population bottleneck was detected approximately 70,000 years ago, and divergence with its relative species occurred about 3.05 million years ago.

Summary: Conservation policies for declining wildlife species are challenging due to multiple environmental changes impacting population declines. Targeted actions to improve local productivity within Europe, combined with large-scale environmental protection across non-breeding ranges, could help halt migrant landbird declines. Such demographic approaches are increasingly necessary to address global wildlife declines.

Summary: Greater emissions of greenhouse gases and climate variability are primary constraints in causing biotic and abiotic stresses. Utilizing genetic diversity among Gossypium species is crucial for the long-term persistence of cotton crops, and utilizing crop wild relatives can help overcome the narrow genetic base of modern cultivars. This review article explores how crop wild relatives can improve tolerance against stresses and discusses the integration of genomic and phenomic platforms for cotton improvement.

Summary: The aim of this study was to investigate the genetic diversity and population structure in the Alpine x Beetal goat population. The results showed that the average inbreeding coefficient and average relatedness were 4.77% and 7.84% for the whole population, and 9.65% and 11.98% for the reference population, respectively. The high inbreeding coefficient and average relatedness in the reference population indicated the impact of a closed gene pool, emphasizing the need for immediate intervention to manage genetic diversity.

Summary: Crozier's paradox suggests that genetic kin recognition is not evolutionarily stable. However, this study shows that allowing for multiple social encounters before each interaction can eliminate this paradox and stabilize genetic kin recognition. Rare tags are better indicators of relatedness and help individuals avoid interactions with non-cooperative cheats.

Summary: Large-scale whaling in the 19th and 20th century led to a significant reduction in cetacean populations, but its impact on the genomic diversity of the fin whale remained unclear. This study examined the effect of whaling on the North Atlantic fin whale and found a noticeable drop in population size a century ago. However, the genome-wide heterozygosity and inbreeding indicators did not show significant changes.

Summary: This study investigates the heterozygosity and population size dynamics of migratory insects using genomic data. The findings show that migratory species have higher levels of genome-wide heterozygosity than nonmigratory species. The study also reveals that migratory Lepidoptera maintain overall genetic diversity and demographic stability despite the risks associated with migration and local environmental fluctuations.

Summary: The study found that Athenaea fasciculata, a plant mainly distributed in the Brazilian Atlantic Forest, was impacted by Pleistocene climate changes. Through genetic and population structure analysis, it was revealed that Athenaea fasciculata differentiated into two groups of populations during the Pleistocene climate changes, each influenced by different climates.

Summary: High-coverage genome-wide sequencing of 14 out of the 15 species of Otariidae revealed a well-supported species tree despite extreme topological discordance among gene trees. The study showed a relatively recent trans-hemispheric dispersal leading to rapid diversification within the southern Glade, with evidence for incomplete lineage sorting and introgression playing a role in explaining genealogical discordance.

Summary: The genetic consequences of the geographic distribution of rookeries in Galapagos fur seals were investigated. The results showed that the rookeries on four islands were genetically structured into three main groups. Gene flow analysis suggested migration from west Isabela to Fernandina islands, with limited migration in other directions.

Summary: This study analyzed the genetic structure of black and gold howler monkeys in 22 study sites in South America. The results showed that the populations in flooded areas had higher genetic diversity, likely due to dam construction. Genetic structure analysis identified differences between regions, and geographic distance influenced gene flow. The study emphasized the importance of considering genetic data in conservation management and environmental impact assessments.

Summary: The study on marine turtles' historical biogeography provides insight into the genetic diversity, connectivity, and population demography of globally distributed species. The findings reveal significant genetic structure among different regions, with the Atlantic Ocean and Indo-West Pacific being more closely related. The dispersal pattern of olive ridleys suggests a male-biased dispersal, and the Atlantic Ocean exhibits the lowest genetic diversity.

Summary: Despite some recent progress, the systematics of the diverse fauna of Neotropical snakes is still controversial. The phylogenetic position of the rare species Echinanthera amoena within the Echinantherini tribe was assessed for the first time in this study. Our results support the monophyly of Echinantherini and indicate a unique lineage for E. amoena. Additionally, the genera Echinanthera and Taeniophallus were redefined based on the results.

Summary: Hybridization is an important source of genetic diversity and evolution, and its role in generating novel lineages has been debated in animals. We provide genomic evidence that the Peruvian fur seal (Pfs) is a genetically distinct species resulting from hybridization between the South American fur seal (SAfs) and the Galapagos fur seal (Arctocephalus galapagoensis) around 400,000 years ago. Our findings support the occurrence of homoploid hybrid speciation in Pfs and highlight the significance of hybridization in promoting biodiversity in large vertebrates.
