Summary: The genus Rineloricaria is a highly diverse group, but only three formally described species have been found in the Tocantins-Araguaia River basin. A recent study discovered a previously undescribed species from the same basin, which can be distinguished from its congeners by its greater number of teeth.

Summary: The study investigated the karyotypes of six species of whiptails armoured catfishes from the South Atlantic hydrographic basin, revealing interspecific diploid number variations. Species with the same diploid number can be easily discriminated by karyotype formulas and the number of 5S rDNA sites. The research suggests that successive vicariant processes promote geographical isolation, enhancing the fixation of chromosomal rearrangements leading to observed karyotypic variabilities.

Summary: Since its discovery in early 1916, dengue fever has caused extensive urban outbreaks in Brazil, posing a serious threat to public health. A genomic surveillance training program was conducted in collaboration with local health authorities, resulting in the generation of 177 DENV genome sequences collected during a period of high dengue fever cases. The study identified the co-circulation of different dengue serotypes and diverse viral lineages, indicating multiple introduction events of viral strains in the region. The findings highlight the complex and changing dynamics of DENV transmission and emphasize the value of ongoing surveillance activities in informing public health actions.

Summary: The study aimed to adjust different probability distribution models to monthly, seasonal and annual rainfall data in the Pantanal of Mato Grosso do Sul, Brazil, and evaluate their performance using quality and information criteria, finding that the 3-parameter Lognormal distribution performed the best in all twelve months. It was observed that the 3-parameter Lognormal distribution is suitable for spring and summer, while the 2-parameter Gamma and 3-parameter Gamma distributions are better suited for winter and autumn seasons, and the 3-parameter Weibull distribution is the best fit for annual observations.

Summary: With the expansion of urban areas, the preservation of fragments and trees has become crucial for biodiversity as they offer both food and nesting sites. This research examines the use of dead palm tree trunks as nesting sites by blue-and-yellow macaws over a period of seven breeding seasons in Campo Grande, Mato Grosso do Sul. The study reveals that out of the 146 natural nests recorded, a majority were found in residential yards (55.5%) and public areas (32.9%). These nests were constructed on dead palm trees of various species. Additionally, 46 nests were lost, with over half being removed by residents (58.7%) and the rest falling naturally (41.3%). Given the significance of vegetation, particularly native palm trees, for breeding and feeding of blue-and-yellow macaws, conservation efforts and encouragement of planting native palm trees in urban areas are essential.

Summary: This study investigates the differences in functional diversity between resident and migratory bird species in Neotropical habitats. The results show that migratory birds add new traits to aquatic groups, indicating high functional turnover, while forest and non-forest groups exhibit greater functional redundancy. There is also higher overlap in functional volume between migratory and resident groups in forest and non-forest habitats compared to aquatic habitats.

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.

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: The study found that repetitive DNAs in Rineloricaria latirostris are predominantly DNA transposons, with A/T-rich expansions being the most abundant. A/T-rich repetitive sequences were scattered on the chromosomes, while A/G-rich microsatellite units were accumulated in some regions. The findings indicate that repetitive sequences such as rDNAs, hAT transposons, and microsatellite units flank probable evolutionary breakpoint regions in R. latirostris.

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, 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.
