Summary: This study assessed the level of genetic introgression between red foxes bred on fur farms in Poland and the native wild population, finding significant genetic differentiation and no strong admixture signals between the two groups. The genetic structure analysis showed distinct clusters for farm and wild foxes, with no threat to the genetic integrity of the species.

Summary: The study conducted on Indo-Pacific bottlenose dolphins in Perth found four behavioral communities with similar genetic structures but small differentiation due to related individuals within communities. The high levels of contemporary migration and related individuals among communities suggest a panmictic genetic population with continuous gene flow. Despite genetic similarity, each social community should be considered a distinct ecological unit for conservation due to exposure to different threats and occurrence in different habitats.

Summary: Cryptic species are closely related taxa that are difficult to distinguish morphologically but are reproductively isolated. The warbling vireo complex was found to have eastern and western genetic groups that have been reproductively isolated for a long period of time, suggesting they may be best treated as separate species. Further research is needed to clarify differences within the western genetic groups.

Summary: Mediterranean finfish aquaculture mainly focuses on the production of gilthead sea bream and sea bass in marine cage farms. Fish escapes pose potential ecological risks to wild populations. The escape rate in the studied fish farm in the Aegean Sea ranges from 0 to 2% per event, occurring 5-8 times a year. Although Mediterranean finfish populations have low genetic differentiation, the risk of genetic introgression still exists.

Summary: Plants and pollinators may have different responses to environmental changes. This study investigated the ability of a specific pollinator species to track the range expansion of its host plant. The results showed that the pollinator species was able to track the host plant's expansion, but there was a reduction in genetic variation and increased differentiation among populations within the expanded range. The findings suggest that plant range expansion caused by artificial introduction may not result in the loss of pollinators, even in obligate mutualisms.

Summary: This study re-assessed the genetic structure of the eastern sand darter using genotype data from microsatellite loci and COI sequencing. A newly discovered population in West Lake, Ontario exhibited a divergent genetic structure, indicating the importance of considering it as a separate conservation unit.

Summary: Genetic variability of Varroa destructor mites varies between different regions, possibly due to the movement of infested bees and climate factors. Mites collected in Canada showed higher variability compared to those in Mexico, which could be attributed to the cooler climate or earlier invasion.

Summary: This study investigates the recolonization of roe deer in Switzerland in the early 1800s and finds evidence of natural immigration from neighboring countries. The study also reveals weak genetic differentiation among different topographic regions in Switzerland. The genetic data support the recognition of a single roe deer management unit in Switzerland and the potential for geographic origin assignment using nuclear markers for law enforcement purposes.

Summary: This study evaluated and characterized the genetic potential of a collection of local onions from the arid region of southern Tunisia for the first time. Genetic diversity was assessed using SSR markers and phenotypic information. The results showed significant genetic variation among individual onions and significant environmental effects on most traits. The findings suggest that new onion varieties adapted to local conditions can be created through hybridization breeding using appropriate parents.

Summary: Estimating turnover in a population provides information on population dynamics, such as dispersal and mortality. By studying genetic diversity and population structure in the Finnish golden eagle population, we found no notable changes in genetic diversity during the 15-year study period and did not discover any population structure. We also examined the turnover rate and found a rate of 23%, which correlated with the breeding success of the previous year.

Summary: The research discussed the genetic diversity distribution and postglacial migration history of grayling in Poland, revealing clear differences in genetic diversity among different populations. The findings indicate that grayling in Poland experienced two distinct postglacial colonization waves.

Summary: CRISPR-Cas9 gene editing was used to establish the conditional viability of knockouts in key proteins involved in mitochondrial DNA replication. The GeneSwap approach was developed for in situ reverse genetic analysis. The functional independence of HMG domains in TFAM opens opportunities for engineered chimeric TFAMs for studying mitochondrial DNA replication, mitochondrial transcription, and respiratory chain function. Furthermore, evidence suggests the leading role of the HMG2 domain in TFAM species-specificity, indicating a potential pathway for TFAM-mtDNA evolutionary co-adaptations.

Summary: Genetic diversity and gene flow barriers are important factors for conserving endangered species. In the case of the endangered yellow-bellied toad in Germany, two genetic clusters were identified, with road densities and urban areas acting as barriers to gene flow. Special attention is needed for isolated populations with low genetic diversity and signs of inbreeding to prevent extinction. Cross-cluster natural gene flow is recommended, but translocation between clusters should be avoided.

Summary: SARS-CoV-2 evades direct killing by natural killer (NK) cells by downregulating ligands for the activating receptor NKG2D. The viral protein Nsp1 mediates the downregulation of NKG2D ligands and alone is sufficient to confer resistance to NK cell killing.

Summary: The peregrine falcon populations show low genetic diversity and some level of genetic structure across Europe. It is suggested that the Sussex peregrines did not originate from escaped domestic birds or adjacent European populations. The study concludes that genetic conservation measures may not be necessary for the Sussex peregrines as long as current protection measures remain in place.
