Summary: In this study, the genetic diversity and population structure of C. balansae in Vietnam were evaluated using microsatellite analysis. The results showed low genetic diversity but high genetic differentiation in the species. Evidence of population size reduction was found in two populations. The study also found a significant positive correlation between genetic distance and geographic distance in C. balansae.

Summary: This study assessed the genetic variation and phylogeographic structure of dolphinfish in the Tropical Eastern Pacific (TEP) using mitochondrial genes and nuclear DNA microsatellite loci. The results showed genetic homogeneity across locations but also genetic differentiation. This could be related to seasonal temperature changes and oceanographic dynamics. Despite the species' abundance, the low effective population size is a conservation concern.

Summary: The European Turtle Dove, a vulnerable species undergoing a long-term population decline, was studied for genetic divergence based on mitochondrial DNA analysis of birds from Spain, Ukraine, and Morocco. Results showed high genetic diversity and distinct genetic groups among the populations, highlighting the need for specific conservation strategies for different regions. Further research and studies are necessary to fully understand the genetic structure of this species.

Summary: Accelerating climate change is causing severe habitat fragmentation in the Arctic, which is threatening the persistence of cold-adapted species. The Scandinavian arctic fox population is highly fragmented and its future survival depends on the northernmost subpopulations to maintain connectivity with the Siberian population. Analysis of arctic fox genomes revealed increasing signs of genome erosion from Siberia to northern Sweden, indicating a stepping-stone model of population connectivity. Inbreeding and the presence of deleterious mutations were more common in the northern Fennoscandian population, while Siberia had more heterozygous mutations. Understanding the genomic consequences of population fragmentation is crucial for conservation efforts in the face of global warming.

Summary: Compared with traditional genetic markers, genomic approaches are valuable for the conservation of endangered species. This study used genome-wide single nucleotide polymorphisms to analyze the genetic diversity and population structure of Paeonia ludlowii, a famous tree peony with rare and pure yellow flowers. The results revealed spatial patterns of genetic variation and suggested that shared ancestry among remnant populations contributes to the subtle population structure. Demographic inference indicated a history of population decline and bottleneck events in P. ludlowii. These findings improve our understanding of the genetic characteristics of this endangered species and have important implications for its conservation.

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: The study reveals a close relationship between American Criollo pigs and Iberian breeds, with Criollo pigs showing higher levels of genetic diversity. Criollo breeds have their own unique identity and share a common genetic background, clustering together even with differences among them.

Summary: Small effective population sizes increase the probability of extinction by increasing potentially deleterious alleles and reducing fitness. It is unknown to what extent cancers contribute to the fitness reduction of genetically depauperate wildlife populations. The study on Santa Catalina island foxes revealed that they have a high prevalence of ceruminous gland tumors, which are associated with chronic ear mite infections and bacterial infections. Several candidate loci associated with cancer susceptibility were identified through whole genome sequencing. The increase in population size and weak fitness effects of late-onset disease may allow selection to effectively remove these slightly deleterious alleles. Long-term monitoring of disease alleles and genetic diversity is crucial for the long-term survival of this threatened population.

Summary: This study examines the influence of landscape features on the genetic connectivity of Thryophilus sinaloa, a common bird species associated with tropical dry forests. The results show that open-areas resistance surface and geographic distance reduce genetic connectivity, indicating that protected areas are partially isolated from other non-protected areas.

Summary: This study aimed to identify the species of and genetic diversity in three populations of Morinda officinalis in Vietnam. The results showed a high similarity between the gene sequences of M. officinalis and the known sequences, as well as high levels of genetic diversity among populations. These findings provide important information for future conservation plans of M. officinalis.

Summary: Population sizes of endemic songbirds on Kaua'i have decreased significantly over the last 10-15 years, primarily due to the threat of invasive mosquitoes and avian malaria. Conservation breeding programs have shown that there is high genomic diversity within individuals, but the populations are still declining.

Summary: Species range contractions, which are both a result and a cause of biological annihilation, do not receive the same attention as extinctions. There are three distinct patterns of range contraction: shrinkage, amputation, and fragmentation. These patterns have significant impacts on population abundance, relatedness, and genetic diversity, with the fragmentation pattern having the strongest effects. Defining and quantifying range contraction patterns and their consequences is crucial for combating biological annihilation.

Summary: The Rufous-backed Bunting in Inner Mongolia exhibits high genetic diversity but shows high levels of gene flow and minimal genetic structuring among fragmented breeding populations. Despite the overall genetic diversity, local populations remain at risk of extinction due to habitat loss, with a high risk of inbreeding within the population. Conservation efforts in Inner Mongolia should focus on protecting breeding habitats and preventing over-grazing to preserve the genetic diversity of this endangered species.
