Summary: Global warming, eutrophication, fisheries overexploitation, species invasions, and habitat loss pose major threats to freshwater biodiversity. A study in 535 Polish lakes of varying morphometry and trophic status revealed 39 fish species, with eight being alien invasive. The number of fish species in the lakes ranged from 1 to 19, and it decreased with increasing eutrophication conditions but increased with larger lake areas and maximum depths.

Summary: Observed range shifts of numerous species into the Arctic and sub-Arctic seas due to ocean warming have led to an increase in local and regional species richness, driven by an increase in sea bottom temperature. While the probability of occurrence for Arctic species generally declined over time, the enrichment of the Arctic and sub-Arctic marine fauna is attributed to an increase in species from southern latitudes, consistent with climate change.

Summary: This study investigated the chromosome evolution of Crepis plants by analyzing the chromosome base number and organization of rDNA loci in 39 species. The results showed that despite variations in rDNA loci organization, most species had rDNA loci on the same chromosome arm. Comparative analysis revealed multiple independent gains of rDNA loci and repositioning during diversification and speciation. These findings provide important insights into the evolutionary mechanisms and speciation of Crepis plants.

Summary: The study models the response of fish diversity to climate variables and finds significant increasing trends in fish diversity in eight major bays along the coast of Texas in fall and spring. Temperature, salinity, and sea level are identified as the most important factors driving the increase in fish diversity. Observed increases are likely attributed to changing habitat availability resulting from sea-level rise and increasing winter temperatures.

Summary: Ocean heat content is crucial for estimating Earth's energy imbalance. A recent intercomparison study of eight oceanic objective analysis products found significant differences in the warming trends in different ocean layers and regions. The study highlights the importance of caution when using a single OA product for OHC studies due to potential product-dependent conclusions.

Summary: Climate change has had apparent impacts on natural systems worldwide, leading many species to struggle to survive in changing environments. Traditional conservation efforts focusing on genetic diversity have shifted towards more active interventions such as protected areas, rewilding, and genetic engineering in order to address the rapid loss of biodiversity.

Summary: Barley, an important feed crop in Iran, is threatened by increased drought frequency. Increasing diversity through evolutionary populations (EPs) and mixtures is a strategy to enhance crop resilience. Evaluations of four barley EPs, two landraces, and one improved variety showed modest differences only in plant height and indicated superior stability of EPs in terms of grain yield reliability. Recurrent droughts may affect diversity within EPs. The nutritional value of EPs will be addressed in future research.

Summary: In this study, we conducted detailed cytogenetic analyses of two caryophyllidean species and found that they have the same chromosome number. Additionally, we identified specific chromosome bands in the caryophyllidean species and confirmed the presence of a major rDNA cluster using fluorescence in situ hybridization. Comparisons between populations from different water bodies also revealed a slightly increased incidence of chromosomal abnormalities in polluted environments.

Summary: By analyzing the U snRNA genes in Apareiodon sp., this study identified nine snRNA multigene families and recognized functional/defective copies. In addition, in situ localization of snDNAs revealed their involvement in chromosomal location changes and dispersion. The findings suggest that defective copies trigger chromosome differentiation and diversification events in Parodontidae.

Summary: This study investigates the differentiation processes and evolutionary history of the rare XX/XY1Y2 sex chromosome system in Harttia species. By using whole chromosome painting probes, the study reveals the existence of homeologous chromosome blocks and the impact of Robertsonian fusions and fissions on sex chromosome origins. The data also support the presence of unstable genomic sites promoting chromosomal differentiation and remodeling within the genus Harttia.

Summary: Population dynamics are influenced by environmental variability, and estimating demographic parameters is crucial for understanding temporal and spatial dynamics. This study used capture-mark-recapture methods to estimate survival rates and population size of a stream-living frog species in a Brazilian state park. Despite seasonal reproduction, the low monthly survival rate suggests that individuals move rather than die, highlighting the importance of recognizing population lability.

Summary: Satellite DNAs (satDNAs) are repeated sequences located on heterochromatin and evolve by concerted evolution. In this study, two satellitomes of Characiformes fish were characterized, showing conservation between species despite divergence 30 million years ago. The results suggest that long-life cycles and few genomic changes may slow down satDNA differentiation rates.

Summary: Cytogenetic studies in armored catfishes revealed that chromosomal rearrangements, particularly Robertsonian (Rb) rearrangements, are responsible for intensive karyotypic diversification. This study focused on the numerical chromosomal polymorphism observed in Rineloricaria pentamaculata and identified a centric fusion event between acrocentric chromosomes 15 and 18. Repetitive sequences, such as microsatellites, played a role in facilitating this rearrangement.

Summary: In this study, the similarity of X and Y chromosomes in four Omophoita species was examined, and genomic differentiation was compared to better understand the evolutionary process of the giant sex chromosomes. The results showed significant genomic similarity between the sexes and a sex-specific region on the Y chromosome, as well as genomic divergence between species. However, whole chromosome painting experiments revealed high intra- and interspecific similarity of the sex chromosomes in O. octoguttata. Our data support a common origin and canonical evolution of the sex chromosomes in this group, as they have high genomic similarity between them.

Summary: A new species of Rhyacoglanis has been discovered in the upper rio Tocantins basin, characterized by its distinct color pattern, caudal fin shape, hypural bones fusion pattern, pectoral-fin spine shape, and barcode sequence of cytochrome oxidase subunit I (COI). This study proposes two putative monophyletic groups of Rhyacoglanis based on morphology - one group consisting of species with a short post-cleithral process and caudal fin with rounded lobes, and another group with a longer post-cleithral process and caudal fin with pointed lobes, including the new species described here.

Summary: In this study, specific probes were used to detect the Gamma, Delta, and Omicron variants of SARS-CoV-2 in 317 COVID-19 positive individuals from Ponta Grossa, Brazil. The Omicron variant, with its high transmissibility, caused a significant increase in COVID-19 infections. Mass testing is considered crucial for controlling COVID-19, and accurate detection of new strains can enhance understanding of the virus's behavior and aid in the development of drugs and optimized vaccines.

Summary: This article revisits the central role of telomeres in chromosomal stability events, discussing their organization, function, and maintenance mechanisms, as well as the involvement of ITS in chromosome changes. While vertebrate telomeres typically consist of a (TTAGGG)(n) sequence, insects show greater diversity in their telomeric motifs. Studies have observed the relationship between ITS and chromosome rearrangements in various species groups, highlighting different types of genome organization and distribution.
