Summary: This study focused on analyzing the repeatome content and abundance patterns in the genomes of 10 gymnosperm species using raw genomic NGS reads. The results showed that known and newly discovered putative repeats in the genomes were specific to phylogenetically close groups of species and aligned with biological taxa. The abundances of known and newly discovered putative repeats closely matched the known taxonomic relations among the species.

Summary: This study analyzed Oligosarcus acutirostris using various cytogenetic techniques and identified the diploid number, karyotypic formula, and chromosomal characteristics of this species. The findings suggest that Oligosarcus genus is prone to chromosomal rearrangements and may be used to detect biogeographical subunits within the coastal Brazilian basins.

Summary: This study investigated the presence of rare earth elements (REEs) in different trophic levels of wild fish species for the first time, showing significant bioaccumulation of LREEs in most species. Based on estimated daily intake (EDI) levels, the consumption of these fish species poses a negligible risk to consumer health.

Summary: Inferring patterns of speciation in marine organisms is challenging due to the lack of species-level phylogenies and information on species' distributions, as well as conflicting relationships between species' dispersal, range size, and co-occurrence. However, a recent study on Carangoidei fish species found that there is widespread sympatry among sister species pairs, regardless of node age, and most species pairs coexist across large portions of their ranges.

Summary: This study identified and characterized the tandem repeats in the genome of Dendrobium officinale using graph-based clustering and FISH. Six major clusters, including satellite DNAs and a rDNA repeat, were identified as tandem repeats. The organization of one cluster was confirmed using PCR amplification and southern blotting. The chromosomal locations and distribution of the repetitive DNAs were investigated, revealing complex chromosomal fusion/segmentation and rearrangements during the evolution of Dendrobium species. This study provides new insights into the differentiation of Dendrobium chromosomes and the chromosome evolution in Dendrobium species.

Summary: This study investigated the karyotype diversity and DNA C values of Dorstenia spp. from the Neotropical region and examined the genomic sequencing of African and Neotropical species. The results showed that polyploidy plays a significant role in karyotype differentiation, but there is no clear relationship between DNA C values and karyotype features or rDNA sites. Dysploidy events and rearrangements involving repetitive fractions are suggested to be responsible for chromosome number variations and changes in genome size.

Summary: Microsatellites (SSRs) and compound microsatellites (CSSRs) in Leptolyngbya-like strains showed diverse patterns of distribution, abundance, density, and diversity in genomes. The numbers of SSRs and CSSRs were unevenly distributed and correlated with genome size and GC content, with differences in distribution patterns among phylogenetic groups. These microsatellites were predominantly located in coding regions, with unique motifs identified in CSSRs in multiple genomes.

Summary: Blue whiting, pouting, and common dab are underutilized fish species with high sustainability potential. They were found to be valuable dietary sources of selenium, with pouting rich in iodine and mussels good sources of iodine and iron. Despite comparatively higher levels of mercury and lead in some species, the contaminants were generally of no concern in both raw materials and products. The semi-industrial products were good sources of selenium and provided appreciable amounts of calcium, iron, copper, and zinc.

Summary: The study shows that healthy aging interventions globally reduce transcripts of noncoding repetitive elements, while aging and high-fat diet increase their expression. The reduction of RE transcripts with healthy aging interventions is associated with biological/physiological processes linked to aging.

Summary: A new species of Thoropa, previously identified as T. lutzi, has been described from the northern region of the Serra da Mantiqueira in Southeast Brazil. The new species is characterized by a combination of features including small size, slender body, and specific characteristics of the nuptial pads. Furthermore, it is only known to exist outside of Rio de Janeiro.

Summary: Mammalian captives, especially folivores and primate dietary specialists, are prone to gastrointestinal distress and suffer the greatest gut microbiome diversity losses in captivity. This study focuses on another dietary specialist group, marmosets, which eat plant exudates. The research reveals that the captive marmosets have a gut microbiome composition similar to that of humans with gastrointestinal diseases, suggesting the need for husbandry modifications to improve the welfare of captive exudivores.

Summary: By documenting and reviewing literature, we have expanded our understanding of the domestic cats' predation on native species in Brazil. The results show that the number of wild species preyed upon by domestic cats may be even higher in other countries with comparable land size and species diversity. Therefore, cat population control measures are recommended, especially in protected areas.
