Summary: Arsenic enrichment in groundwater resources in deltas and floodplains of large sediment-rich rivers poses a worldwide natural hazard to human health. The high spatial variability of arsenic concentrations in affected river basins hinders the implementation of cost-effective mitigation strategies. Linking the chemical composition of groundwater with topography and fluvial geomorphology shows promise in predicting arsenic pollution on a regional scale. In the Amazon basin, arsenic contamination in wells was found to be correlated with fluvial dynamics.

Summary: This study reviews the biodiversity of Liogenys species in northern South America and Central America, describing four new species and providing gender descriptions for two known species for the first time. A new junior subjective synonym is identified, and three species are transferred to a different genus. An identification key to northern South American Liogenys is presented.

Summary: This paper investigates the origins, trend, and drivers of institutional timberland investment in South and Central America. It notes that domestic institutions in South America have been a distinctive source of, and a significant contributor to, the rise of institutional timberland investment globally in the past six-plus decades. The paper further shows that foreign institutions have increased their timberland investment in the region since the 1990s, motivated by seeking high risk-adjusted returns.

Summary: Latin American countries face challenges in defining and understanding their culturally diverse region. The fragmented health systems, combined with a rapidly ageing population and increasing demands for care, contribute to the unpreparedness of health systems and the burden of disease. This article analyzes the burden of disease and identifies priorities to improve care and quality of life in the region.

Summary: This paper assesses the state of knowledge of climate change and tourism in South and Central America, focusing on the characteristics of the tourism sector, climate risks, and GHG contribution. The authors conducted a literature review and searched for institutional publications, programs, and strategies. The analysis identified the main challenges and potentialities between tourism and climate change, including the limited number of studies and lack of primary data, as well as scarce tourism-specific policies and recent development of multisectoral climate plans.

Summary: This study analyzes the geographic variation of lightning characteristics using data from the Earth Networks Total Lightning Network. The results show significant differences in lightning characteristics in different regions, such as higher average peak current in Northern Argentina and a localized minimum in a specific region North of S??o Paulo, Brazil. The study also observes a higher proportion of positive cloud-to-ground lightning in Central and Northern Argentina compared to conventional thunderstorms.

Summary: This study analyzed the mitogenome of the South American parthenogenetic lizard Loxopholis percarinatum from the Rio Negro region in Brazil, finding typical vertebrate mitochondrial gene content and order. Additionally, a phylogenetic analysis placed L. percarinatum with the only other available species in GenBank from the Gymnophthalmidae family, Iphisa elegans.

Summary: The study highlights the increasing trend in heat wave frequency, intensity, and duration in central South America since the 1980s. Based on data from September to November 2020, an intense heat wave resulted in record-breaking high temperatures in several locations in central South America, with temperatures rising about 10 degrees Celsius above normal and exacerbating severe drought and wildfires.

Summary: This study constructed the first Pn velocity and anisotropy model of the uppermost mantle in Central and Northwestern South America. The results showed significantly low Pn velocities and arc-parallel anisotropic structures beneath the volcanic arc in Central America. Furthermore, a separate, low Pn velocity was observed beneath a back-arc volcano in Nicaragua, indicating the separation of hot material upwelling in the uppermost mantle beneath this volcano from the main volcanic arc. Additionally, the stable Caribbean Plate exhibited high Pn velocities.

Summary: Podostemaceae are a widespread family of aquatic angiosperms, and their associations with arthropods have been understudied. This study examined Podostemaceae samples from Brazil, Costa Rica, Suriname, and Venezuela and found over 9000 arthropods representing 12 different orders. The findings contribute to the understanding of the arthropod-Podostemaceae associations.

Summary: Speleothems can provide continuous and high-quality records of the geomagnetic field. The paleomagnetic records of a mid-to-late Holocene stalagmite from Brazil show small angular variations and relatively steady paleointensity, contrasting with the fast variations observed in younger speleothems from the same region.
