Summary: The genetic diversity and structure of European bison in Lithuania were examined using microsatellite markers and mtDNA sequences. The study found that the Lithuanian population has a different genetic structure compared to populations in Poland, Germany, and Sweden. It also revealed low genetic variation in the Lithuanian bison population, with two haplotypes observed in the mtDNA sequences.

Summary: The study highlights the importance of genetic diversity for species adaptability and survival, emphasizing the need for monitoring to ensure maintenance. Data showed that some species may have an effective population size, while information on remaining populations or historical range was available for only 20% of species. Additionally, genetic diversity in some species is being monitored using DNA-based methods.

Summary: Urban landscapes pose barriers to wildlife movement and gene flow, impacting genetic diversity and structure of large terrestrial mammals such as the eastern grey kangaroo. This study examined the genetic profile of kangaroo populations in a rapidly urbanising region of Southeast Queensland, Australia and found regional genetic differentiation and declines in effective population size. The findings highlight the need for localized management and improved landscape connectivity to preserve genetic diversity and structure in the face of ongoing urbanization.

Summary: Chloroplast assembly is challenging due to large inverted repeats, but accurate assemblies are important for biogeography and population genetics studies. A study on European Beech chloroplast genomes revealed an inverted orientation of the single-copy region and potential loci for future SNP-based studies. The low divergence suggests limited seed dispersal but high pollen dispersal, with implications for tracing migration history in the Holocene.

Summary: This study investigated the genetic resources of black poplar from the Oder valley in Poland, revealing high genetic variability and past bottlenecks in the populations. The findings suggest genetic substructuring and potential conservation units for this species in Europe. The Oder River valley still holds substantial genetic resources of black poplar, but there are signs of isolation by distance and genetic erosion.

Summary: This study investigated the potential drivers of genetic diversity in different semi-natural grassland types, revealing clear differences in genetic diversity drivers between calcareous grasslands, hay meadows, and litter meadows. The results showed that landscape structure was the primary driver of genetic diversity in calcareous grasslands, while habitat age, habitat quality, and population size were additional drivers in hay meadows and litter meadows. The study concludes that maintaining high levels of intraspecific diversity in different grassland types requires considering different drivers of genetic diversity.

Summary: This study evaluated the genetic diversity of Astragalus cyclophyllon populations in Iran and found that genetic diversity is high. The major threat to this species is not inbreeding depression, but instead changes to the population structure due to livestock grazing.

Summary: Habitat fragmentation has negative effects on population sex ratios, genetic diversity, gene flow, mating patterns, and early progeny vigor in dioecious, wind pollinated trees, which poses a serious threat to their long-term persistence.

Summary: This study aimed to characterize the genetic variability and structure of Mangaba genebank of Embrapa Tabuleiros Costeiros, and define a core collection. The results showed that the genetic variation of Mangaba genebank mainly exists within accessions, indicating high genetic diversity. The core collection retained 94.9% of the identified alleles.

Summary: This study proposes a new approach for selecting target sites for a network of genetic conservation areas (GCAs), taking into account the current genetic variation. It suggests that the inclusion of further sites is necessary when establishing GCA networks for multiple species. However, it also emphasizes that genetic variation is not the only relevant parameter, and other factors such as property situation, funding availability, and land use history should be considered in the decision-making process.

Summary: This study found that short-term climate fluctuations can significantly alter the genetic composition and diversity of certain populations, which has rarely been addressed in previous literature. The intensity of environmental selection is expected to be greatest in regions with the least stable short-term climatic conditions.

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: When new mutations arise at functional sites, they are more likely to have negative effects on fitness. This is particularly important for the inbred Scandinavian wolf population, which was founded by a small number of wolves in the 1980s and suffers from inbreeding depression. The study reveals that genetic drift and inbreeding in this population have led to an increase in deleterious mutations, but the arrival of immigrants temporarily rescued the genetic load. However, without permanent connectivity to other populations, inbreeding again exposed the population to deleterious mutations, highlighting the importance of gene flow in managing endangered populations.

Summary: This study aimed to investigate the impact of introducing Scots Pine on the mesofauna of the forest floor in Central European oak-hornbeam forests, particularly focusing on terrestrial gastropods. The presence of pine trees was found to significantly reduce the abundance and diversity of gastropods, leading to an overall negative effect on the gastropod assemblage in the long term. A multifactorial combination of habitat factors, including herb layer cover, moisture, fertility, calcium content in the soil, and insolation, was identified as significant in shaping the gastropod community structure. This highlights the importance of considering both macro- and micro-level environmental factors for biodiversity management in forests.
