Summary: The study introduces a new empirical ground-motion prediction model for subduction events in northern South America, utilizing an updated ground-motion database curated by the Colombian Geological Survey. Regional terms are estimated with records from 60 subduction events in Colombia and Ecuador, considering different geological factors that may influence ground motions.

Summary: Differences in tree species richness between South America and Africa are primarily due to certain key families in South American moist forests and dry vegetation types. The tree floras of South America and Africa are organized similarly, and further research on these key families could provide insights into the processes leading to South America's exceptional plant species diversity.

Summary: This study explores the distribution patterns of Neotropical odonates and finds a Rapoport effect in the Amazon biome and an inverse Rapoport effect in the Amazon-Cerrado Transition Forest and Cerrado biome. Regarding the Latitudinal Diversity Gradient (LDG), there is no significant correlation between species richness patterns and latitude for all species, but there is a significant relationship between species richness and latitude for zygopterans.

Summary: In South America, the rise of shell mound cultures along the Atlantic Forest coast of Brazil was dependent on fishing for sustenance, with its significance growing over time. However, around 2200 years ago, a sharp decline in the frequency of shell mound sites and radiocarbon dates occurred, likely due to the fragmentation of social units and changes in coastal environments.

Summary: This article presents a regional ground-motion model developed using earthquake data from Colombia, Ecuador, and Venezuela for seismic hazard assessment in northern South America. The model corrects the misfit of global ground-motion models in the region for moderate magnitudes and intermediate to large distances.

Summary: The study found that the spread of Aedes aegypti populations to southern locations may be the result of the mosquito's adaptation rather than directly caused by climate change. As the geographical location moves southward, the impact of diapause on the population becomes increasingly significant.

Summary: This study reported the emergence and molecular characterization of the IBV GI-23 in South Brazil, being detected for the first time in South America. A total of 82 broiler flocks were tested and most of them belonged to GI-23.

Summary: In this study, a ground-based camera technology was used to retrieve atmospheric precipitable water vapor (PWV), and it was shown that PWV can be retrieved from prior knowledge of the local humidity profile. This method can be used for daytime or nighttime retrievals under partly cloudy sky conditions.

Summary: The Great Acceleration since the mid-20th century has caused significant losses in ecosystems, biological species, languages, and cultural diversity. To address this, the integration of ecological calendars and the 3Hs model of the biocultural ethic can reconnect society with biocultural diversity. Biocultural calendars emphasize the co-constitutive nature of dynamic biophysical and cultural processes and enhance the integration of Indigenous and scientific knowledge to confront climate change challenges. This concept can be applied to different ethnolinguistic communities to understand the links between cultural practices and the life cycles of biocultural keystone species.

Summary: This study aims to evaluate the interaction between climate and biome structure in explaining changes in species richness of soil-associated communities due to tree plantations. Through a meta-analysis of 127 study points across South America, the response of plants, soil invertebrates, and soil microorganisms to tree plantations was compared. The influence of biome structure and climatic factors on species richness was assessed, and both anthropogenic variables significantly reduced the change in species richness.

Summary: In this study, the genetic diversity of Epstein-Barr virus (EBV) in Brazil was characterized. Four main EBV clades were identified, with the Raji/Argentine and Mediterranean clades being the most prevalent in South America. The Raji/Argentine clade showed associations with certain polymorphisms and high haplotype diversity.

Summary: This study analyzes the evolution of population structure and genetic diversity of Braford cattle in South America from 1949 to 2019 and suggests effective breeding strategies for the future. The study found that the percentage of bulls in the breed has increased over time, while the average generational interval has decreased. Inbreeding and coancestry rates have been historically low but show an increasing trend. The study also observed a shift towards mating similar individuals and an increase in the relatedness coefficient. A single ancestor explains a significant proportion of the breed's gene pool. While genetic diversity loss is small, overuse of individual bulls may lead to long-term reduction in diversity.

Summary: This study identified four genetic groups in the lowlands of South America based on maize dispersal patterns correlated with endosperm types. Spatial analysis of genetic variation suggests different dispersal routes for each endosperm type, potentially associated with expansions of different indigenous groups in the region.
