Summary: Over the past three decades, studies on tree diversity in South America have mainly focused on trees with certain stem diameters, while neglecting the largest canopy and emergent trees. In this study, a machine learning approach was used to analyze the importance of environmental factors in predicting tree species diversity in the Brazilian Amazon. Environmental variables related to disturbances were found to influence the diversity of large trees, while variables related to resources were more important for overall tree diversity. The study also identified specific regions with high diversity of large trees and general tree species diversity, highlighting the role of climatic and topographic stability in promoting species diversity.

Summary: The high rates of N-2 fixation in the Western Tropical Atlantic Ocean are mainly due to the influx of nutrients from the Amazon River. In this study, a regional model was used to investigate the impact of the Amazon on different factors controlling N-2 fixation. The simulations showed that the Amazon enhances marine N-2 fixation, with most of the enhancement driven by DDAs.

Summary: The expansion of livestock production and agriculture has led to an increase in deforestation rates in the Amazon rainforest, impacting climate and biodiversity. Studies show that deforestation increases the diversity and abundance of antibiotic resistance genes in soil, posing a potential threat to global health and food security. Further research is needed to understand the transfer of these genes through food chains and their impact on antibiotic treatment effectiveness and public health.

Summary: A review of unpublished archival material in Peru revealed over 400 known but unpublished archaeological sites in the Department of Loreto, challenging the idea that the region was sparsely occupied in prehistory. The database provides geolocation and references for each site, aiding scientists in understanding Pre-Columbian human occupation, cultural change, and landscape legacies in the Amazon basin. These data are crucial for informing current land use policies, forest conservation efforts, and initiatives supporting indigenous rights in the region.

Summary: The red king crab (RKC) larvae have an important impact on the spread and recruitment of the population in the Barents Sea. They have different characteristics compared to their counterparts in the North Pacific. RKC larvae can be found in coastal plankton from late January to mid-July, with the highest densities in semi-enclosed bays with weak water exchange. They perform daily vertical migrations, diving during daylight and rising at night. RKC larvae feed on both phyto- and zooplankton.

Summary: Viruses play diverse and important roles in ecosystems, and trade-offs between host and virus traits are crucial in viral ecology and evolution. An individual-based evolutionary model is developed to study ecological interactions and evolution between bacteria and viruses, focusing on the impacts of trade-offs between competitive and defensive host traits on population dynamics and trait diversification. The model demonstrates the importance of trade-offs in shaping biodiversity and provides insights into the effects of environmental and organismal parameters on virus-host dynamics.

Summary: Life on Earth has evolved from simplicity to complexity, with bacteria and archaea excelling in metabolic diversification and eukaryotes displaying morphological innovation. The Earth BioGenome Project proposes sequencing the genomes of all known eukaryotic species to create a digital library of life, which will help address evolutionary and ecological questions and provide insights into speciation, adaptation, and organismal dependencies within ecosystems.

Summary: Taxonomical and functional facets of diversity play a crucial role in understanding the effects of landscape transformation on species assemblages. This study found that anthropogenic land cover types have an impact on anurans, with larger species showing a preference for anthropogenic land cover. The congruence between functional diversity and taxonomic diversity metrics changed when comparing different land cover types, and certain diversity indices were more sensitive to land-use change.

Summary: The Amazon River plume has a significant impact on the carbonate chemistry in the western tropical North Atlantic. By conducting sensitivity tests, we found that adding alkalinity through quicklime in the Amazon River watershed can alter carbonate chemistry and reduce carbon dioxide emissions at the river mouth.

Summary: This study analyzed the morphology and suspended sediment concentration (SSC) dynamics of the Mocajuba estuary. It found that the estuary is tide-dominated with rectangular areas instead of the typical funnel-shaped morphology. The estuary's deep characteristics and estuarine circulation resemble fjord systems, influenced by tectonic events and structural evolution. The seasonal conditions affected the salinity and SSC, with higher salinity in the dry season and higher SSC in the rainy season. The Amazon River Plume played a significant role in providing fine sediments to the estuary and adjacent mangroves.

Summary: We studied the ice-nucleating particles (INPs) in the plumes of the Tocantins and Amazon rivers, which have varying proportions of degraded land. The concentration of INPs active at -15 degrees C (INP-15) was significantly lower in the Tocantins compared to the Amazon and Atlantic surface waters. The differences in heat tolerance suggest that the sources of INPs from the Amazon rainforest vary depending on their location within or below the canopy.

Summary: The aim of this study was to assess the environmental factors that modulate the spatiotemporal distribution of Petrolisthes armatus and analyze their population structure, dynamics, and secondary production in an Amazon estuary. It was found that crab density was positively correlated with salinity and negatively correlated with temperature. Factors such as dry season, eastern bank, lower estuary, larger rock substrate, and lower intertidal zone contributed to higher crab density. This study provides valuable insights into the population dynamics and ecological role of P. armatus in the Amazon estuary.
