Summary: This study revisited 100 populations of slender wild oat that were screened genetically 40 years ago. The results showed that the mesic ecotype, which is associated with moist environments, had higher adaptability in both moist and dry habitats, while the xeric ecotype, associated with dry environments, had declined in range and frequency. The genetic sequencing of modern populations revealed genetic uniformity within each ecotype, and additional introduced genotypes have spread even further than the mesic ecotype into the former range of the xeric ecotype.

Summary: Genomic network analysis of 430 modern individuals across 21 Pacific island populations sheds light on the settlement history of Polynesia. The reconstruction reveals a serial founder expansion originating in Samoa, spreading through various islands over centuries. This detailed genetic history provides insights into the migration patterns and connections between different Polynesian cultures.

Summary: Simple models have been widely used in theoretical ecology to understand population dynamics, with the Levins model serving as a seminal example for continuous-time metapopulation dynamics. Our study aims to develop a discrete-time metapopulation model using difference equations, focusing on colonization and extinction processes. Through our approach, we illustrate how properties of colonization and extinction functions can impact metapopulation dynamics, with the potential for complex behavior such as cyclic and chaotic dynamics in non-monotone models.

Summary: By utilizing molecular phylogenetic analysis, this study investigated the evolutionary history of the land snail genus Acusta in East Asia, revealing that the recognized species in Acusta are polyphyletic and challenging previous assumptions about the colonization of East Asian islands via land bridges during the Pleistocene glaciations. The genus originated in the late Miocene-Pliocene from an area around North and Northeast China to South China and East Asian islands, leading to three major evolutionary lineages with distinct evolutionary histories.

Summary: This study explores the effects of introgression and historical demography on the genetic variation of two independent-originated endemic snakebark maples in Taiwan. It finds that recent introgression, rather than common ancestral polymorphism, is the main cause of genetic admixture between species. Furthermore, the study reveals that the impact of introgression on demographic history differs between the two species, especially in terms of altitude expansion directions.

Summary: In this study, a freshwater snail attached to a Latham's snipe was identified as the genus Glyptophysa through morphological and molecular identification. Considering the migration route of the bird and the distribution of the molluscan genus, it was concluded that the snail was attached to a bird which migrated over 4000 km across the ocean. This finding demonstrates long-distance dispersal on an intercontinental scale by a migratory bird, confirming a long-standing presumption in biology.

Summary: Repeated colonizations and resultant hybridization have increased lineage diversity on Muna Island. The history of multiple colonizations and hybridization events were reconstructed using genetic analyses. These mutual colonizations and introgressive hybridizations shaped the current biodiversity of the Oryzias woworae species group in this area.

Summary: The relationship between population genetic structure and metacommunity structure is still unknown, but regional variation in environmental characteristics and spatial structure influences resulting biodiversity patterns differently. Metapopulations and metacommunities both exhibit greater spatial and environmental structuring at larger spatial scales, responding to different subsets of environmental variables.

Summary: It is found that the mutation load in an admixed population resulting from introgression between individuals with different N-e is intermediate between those of the parental populations and positively correlated with the proportion of ancestry of the subspecies. Therefore, considering the genetic admixture of populations is crucial in estimating mutation loads.

Summary: This study investigates the phylogeography and connectivity of the deep-sea hydrothermal vent snails of the genus Alviniconcha in the Western Pacific and Indian Ocean. The study reveals the divergence and population structure between different vent fields, suggesting possible allopatric speciation. The findings contribute to the understanding of speciation and connectivity of vent species in the Indian Ocean.

Summary: The study focused on the toxicity test of cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) using juvenile and adult apple snail Pomacea insularum as test organisms. The results showed that Cu was the most toxic metal to the snails, and the juveniles were more sensitive than the adults. The study demonstrated that P. insularum can be recommended as a good biomonitor for these metals in freshwater ecosystems.

Summary: The maintenance and use of the immune system is energetically costly and dependent on the nutritional state of the host. The condition dependence of immune function in freshwater snails was examined, revealing that the type and level of resources consumed influenced their immune activity. Additionally, the snails' energy reserves were found to be negatively correlated with immune activity.

Summary: Estimating contemporary effective population size, sibship, and parentage is crucial for designing and monitoring plant translocations. These analyses provide valuable insights into genetic relatedness, selfing rates, and the genetic quality of transplants, contributing to a more precise evaluation of population viability and extinction risk.

Summary: The study describes the isolation of two strains of PUUMALA orthohantavirus from two distinct French geographical areas: Ardennes (endemic area) and Loiret (non-endemic area). By selecting wild bank voles, cultivating the strains efficiently in Vero E6 cells, and propagating them in immunologically neutral bank voles, the impact of isolation methods on viral diversity was better assessed through high-throughput and Sanger sequencing results.

Summary: Toll-like receptors play a central role in host defence against pathogens, with recent studies showing high polymorphism in Tlr genes. Research on the relationship between Tlr genotypes and pathogen infections reveals the impact of pathogen-mediated selection on innate immunity genetic diversity. These findings emphasize the importance of looking beyond MHC genes in wildlife immunogenetic studies and considering multiple pathogen challenges for a better understanding of vertebrate defence evolution.

Summary: This study investigated the circulation of PUUV in its animal reservoir during a large outbreak of NE in the southern Jura Mountains in France. The results showed a higher abundance of bank voles in 2021 compared to previous years and a high seroprevalence of PUUV in the captured animals during the human NE epidemic. Genetic analysis revealed clustering of PUUV strains without significant genetic variation.
