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: The study found that there is a significant but varied relationship between air pollution and the spread of COVID-19 in different cities across South America. Even for the same region, different models may provide inconsistent results, suggesting the need to select models based on local conditions.

Summary: This article suggests a regional approach to achieving energy security in South America, using an Open Source energy Modelling System to create scenarios with different levels of energy integration. The study shows that more integrated scenarios lead to a reduction in the need for increased installed capacity, lower geographic and socio-environmental impacts, and mitigation of greenhouse gas emissions.

Summary: ENSO events have been studied extensively due to their significant impact on climate and weather in South America. Most attention has been given to the warm phase (El Nino events) during the austral summer. However, it is still unclear how the teleconnection patterns are modified based on the different intensities of ENSO events in different seasons, and the subsequent impact on South America. This study aims to investigate how the different phases, intensities, and seasons of ENSO events modulate the Stationary Rossby Waves that impact South America. A tool called raytracing was developed for this purpose. The distribution of SST anomalies influences ENSO intensity, with higher and wider anomalies leading to stronger ENSO events. Weak ENSO events result in weak anomaly precipitation over South America, particularly in the southeast region. The position of stationary Rossby waves varies during El Nino and La Nina events, with El Nino causing them to be slightly closer to the equator and La Nina positioning them poleward. The wave shape and amplitudes remain constant during summer events regardless of ENSO intensity, demonstrating the robustness of precipitation anomaly patterns over South America. However, in other seasons, these wave features exhibit larger variations and heavily influence the position and signal of precipitation anomalies over South America, with positive anomalies associated with downstream crests and negative anomalies associated with downstream troughs/upstream crests.

Summary: Dams and their reservoirs play a significant role in society and the environment, facilitating water resource management while potentially causing adverse impacts related to safety, ecology, and biodiversity. Studies suggest that climate change could exacerbate these impacts, underscoring the importance of continuous monitoring and research on dams.

Summary: This study revisited Kelvin waves over tropical South America, identifying two main types associated with Pacific and South American precursors. Events with a Pacific precursor are more common during ENSO warm events, while those with South American precursors show stronger activity during La Nina events. Other triggering mechanisms of CCKWs over the Amazon were also explored in the analysis.

Summary: This study used a cultural evolutionary perspective to analyze musical instrument data in South America, finding correlations between geographic patterns, language families, and instrument collections of different populations, particularly the distribution of wind instruments like panpipes and cultural clusters. A network analysis revealed four distinct regional/cultural clusters, and showed that European contact led to a reduction in indigenous cultural diversity.

Summary: Oceanic heat sources disrupt the atmosphere, leading to waves that affect climate in remote regions like South America. Eight teleconnection patterns, including ENSO, PDO, AMO, TAD, SAD, SAM, MJO, and IOD, play significant roles in influencing precipitation and wind anomalies in the region. The most affected areas are southeastern South America and the north sector of Brazil, characterized by a precipitation dipole pattern between them during each teleconnection pattern.

Summary: A tooth from the Late Cretaceous in Argentina suggests the presence of monotremes in South America at the end of the Mesozoic Era. Monotremata, a group of egg-laying mammals represented by the platypus and echidnas, is endemic to Australia and nearby islands. The discovery of a Late Cretaceous monotreme in southern Argentina indicates their presence in circumpolar regions and suggests that their distinctive anatomical features were already present in ancient forms.

Summary: This work evaluates the ability of 28 CMIP6 models to represent the South American climate during the reference period and finds that some models perform poorly in representing specific systems, with most models overestimating the intensity of the subtropical and polar jets.

Summary: This study describes the climatological characteristics of regional heat waves (HWs) over southern South America (SSA) for the warm seasons of 1979-2018. It identifies regional HW events in five homogeneous regions based on clustering of stations with high co-occurrence of simultaneous HW days. The analysis reveals differences in duration, intensity, and extension of HWs among the regions, with the southernmost region exhibiting the most severe HWs. Long-term assessments indicate significant increases in the frequency of regional HW days over central Argentina and central Chile, and the severity of HWs has increased only in the southernmost region.

Summary: The article describes the rare Late Triassic large tetrapod tracks found on the shoreline near Penarth, south Wales, UK, as well as the digital mapping of site erosion during 2009-2020 using historical photogrammetry. The loss of over 1 meter of the surface exposure and the deterioration of the tracks highlight the transient and vulnerable nature of fossil resources, emphasizing the importance of efficient data collection.

Summary: The family Nemesiidae was once species-rich but is now considered paraphyletic. Recent studies have led to controversial changes in the systematics of Nemesiidae, with some genera transferred to the family Pycnothelidae. This study aims to evaluate the phylogenetic relationships of South American nemesioid species and genera for proper family level placement, providing a robust framework for the family Pycnothelidae.
