Summary: Bs in Apodemus flavicollis are genetically similar across geographically distinct populations and play a significant role in gene expression, particularly for genes related to age and sex. The preservation of Bs in all samples indicates their biological importance and challenges the notion that Bs are genetically inert.

Summary: The Rustrela virus (RusV) was found in yellow-necked field mice as a reservoir and showed high diversification in northeastern Germany. The virus had a high level of genetic variability and was mainly distributed in the central nervous system. The study suggests the need to assess the zoonotic potential of RusV and investigate encephalitis cases in mammals.

Summary: This study investigated the spatial organization of Bs in the interphase nucleus of the yellow-necked mouse through microdissection and DNA probe experiments. It was found that Bs are located peripherally within the nucleus and may interact with the nuclear envelope, indicating a potential role in nuclear architecture regulation similar to pericentromeric regions of autosomes and sex chromosomes. This suggests that Bs may utilize a mechanism similar to sex chromosomes to avoid meiotic checkpoint.

Summary: New information on the distribution of the yellow-necked mouse to the east is presented, with the species recorded for the first time in the northern part of the Ilmenskii Reserve. Conformational and craniometric characteristics of individuals are provided, suggesting the invasion occurred due to climate change. The easternmost point of the modern range of the species was found in the Ilmenskii Nature Reserve.

Summary: This study investigated the presence and potential causes of sex bias in ectoparasite infestations in yellow-necked mice. The results showed that male mice had a higher tick burden compared to females, but this difference was driven by their body mass rather than their sex. Additionally, the abundance of ticks and fleas infesting yellow-necked mice varied over time.

Summary: The karyotypes of 95 specimens of yellow-necked field mouse caught in Eastern Europe were studied. Only one specimen had an extra chromosome. It was shown that the frequency of individuals with B chromosomes in Sylvaemus flavicollis from the surveyed sites in Eastern Europe is very low and probably not influenced by ecological conditions.

Summary: The study shows that rule changes such as the introduction of the 'Half-Game Rule' in youth rugby lead to increased enjoyment and engagement among players, ultimately raising their intentions to continue playing the sport. This supports the use of Competitive Engineering (CE) to enhance player enjoyment in team sports and potentially reduce drop out rates in youth sport.

Summary: The study found that one-quarter of children aged 2-5 in Turkey play video games, with a higher prevalence among older children, males, families with lower parental education and more children. Parents should be informed about supervising their children's video game habits and choosing games with appropriate content.

Summary: The new game NinjaMath is designed to help undergraduate students at the Metropolitan Technological Institute of the city of Medellin in Colombia learn factorization to reduce high dropout rates in math subjects. The game considers three key elements - game rules and mechanics, narrative, and aesthetics - that contribute to developing students' cognitive skills.

Summary: This study aimed to investigate the species assemblage, genetic diversity, and host specificity of bat flies and wing mites found on Schreiber's bent-winged bat Miniopterus schreibersii and greater horseshoe bat Rhinolophus ferrumequinum in Serbia and Bosnia and Herzegovina. The findings show that despite direct contact among hosts, there is a high degree of host specificity and segregation among ectoparasite species.

Summary: This study analyzed intestinal nematodes in three small rodent species and found that animals in better condition had higher parasite species richness. In A. flavicollis, females had more parasite species than males of the same body condition. Contrary to expectations, spleen mass did not reflect changes in parasitism level, but in M. glareolus, a smaller spleen was related to a higher parasite load.

Summary: In this study, we describe the satellite DNA families found in two snake species from different families. Contrary to common belief, we found high conservation of these satellites in terms of nucleotide sequences and chromosomal localizations. Satellite DNA sequences make up a large portion of animal genomes, and they are typically located in heterochromatin clusters near centromeres or telomeres. The function of these clusters is to maintain chromosome and nuclear structure, and regulate chromosome behavior during cell division. Understanding satellite DNA diversity is important for studying sex chromosome evolution, hybridization, and speciation. Through our research, we identified four satellite DNA families in two snake species and determined their chromosomal localization. We found that one family is localized in the centromeres of both species, while the others form clusters on specific chromosomes or subsets of chromosomes. Our results demonstrate the high conservation of satellite DNA in snakes and support the library model of satellite DNA evolution.

Summary: The media plays a crucial role in shaping people's attitudes towards conservation issues. Understanding how bats are portrayed in the media is important for bat conservation, especially given recent fearmongering and misinformation about bat-related risks. In this study, we reviewed bat-related articles published in 15 newspapers from Western Europe's five most populated countries before 2019. We analyzed the portrayal of bats as a threat to human health, the general attitudes towards bats in these articles, and the readers' responses.

Summary: This study investigated the prevalence and distribution of Polychromophilus parasites in European bats and their nycteribiid vectors. A total of 215 bat flies collected from two bat species in Serbia were screened for Polychromophilus infections and analyzed by gene sequencing. The results showed a high diversity of P. melanipherus parasites in Miniopterus hosts and suggested regular encounter with this parasite in secondary hosts.

Summary: We studied the variation of constitutive heterochromatin in the genome by analyzing a group of species with conserved euchromatin. Our findings showed the distribution of different tandemly repeated sequences and the conservation of euchromatin among these species. The variation and prevalence of these repetitive sequences are responsible for the species-specific variation of heterochromatic blocks.

Summary: This study aimed to expand our knowledge on the genetic diversity of Altai horses in Siberia. By studying modern horses from two Altai regions and ancient horse bone samples, the study confirmed the hypothesis that Altai horses are represented by two populations (Eastern and Southern) and that Mongolian horses have a closer genetic relationship with Eastern Altai horses. The results also showed that most ancient horse haplotypes are present in modern Altai horses, and the differences between the mitochondrial gene pools of ancient Altai and Mongolia horses are more significant than those of modern horses in the respective regions due to increased migration processes.

Summary: Researchers have described the karyotype of the small-toothed mole from Vietnam for the first time and identified cytogenetic signatures for this species and other related moles. They have also proposed a possible ancestral karyotype and found that pericentric inversions and heterochromatin amplifications are the most occurring types of chromosomal rearrangements in moles.

Summary: B chromosomes are additional chromosomes beyond the standard chromosome set, and Leisler's bat is one of the few bat species with detected B chromosomes. The number of B chromosomes varies among individuals and populations, as well as within individual cells. B chromosomes are more common in rodents than in bats.
