Large and increasing methane emissions from eastern Amazonia derived from satellite data, 2010–2018 by C. Wilson, C. Wilson, M. P. Chipperfield, M. P. Chipperfield, M. Gloor, R. J. Parker, R. J. Parker, H. Boesch, H. Boesch, J. McNorton, L. V. Gatti, J. B. Miller, L. S. Basso, S. A. Monks, S. A. Monks, S. A. Monks

“…<p>We use a global inverse model, satellite data and flask measurements to estimate methane (CH<span class="inline-formula">₄)</span> emissions from South America, Brazil and the basin of the Amazon River for the period 2010–2018. We find that emissions from Brazil have risen during this period, most quickly in the eastern Amazon basin, and that this is concurrent with increasing surface temperatures in this region. …”

Proliferation of hydroelectric dams in the Andean Amazon and implications for Andes-Amazon connectivity. by Matt Finer, Clinton N Jenkins

“…We examined the potential ecological impacts, in terms of river connectivity and forest loss, of the planned proliferation of hydroelectric dams across all Andean tributaries of the Amazon River. Considering data on the full portfolios of existing and planned dams, along with data on roads and transmission line systems, we developed a new conceptual framework to estimate the relative impacts of all planned dams. …”

Diversification of Amazonian spiny tree rats in genus Makalata (Rodentia, Echimyidae): Cryptic diversity, geographic structure and drivers of speciation by Cleuton Lima Miranda, Izeni Pires Farias, Maria Nazareth F. Da Silva, Alexandre Antonelli, Arielli Fabrício Machado, Rafael N. Leite, Mario Da Silva Nunes, Tadeu Gomes De Oliveira, Julio Cesar Pieczarka

“…We identify two key events for the expansion and diversification of Makalata species: the presence of geologically stable areas in the Guiana and Brazilian shields and the transition from lacustrine conditions in western Amazonia (Acre system) to a river system, with the establishment of the Amazon River transcontinental system and its tributaries. …”

Dispersal and Diving Adjustments of the Green Turtle Chelonia mydas in Response to Dynamic Environmental Conditions during Post-Nesting Migration. by Philippine Chambault, David Pinaud, Vincent Vantrepotte, Laurent Kelle, Mathieu Entraygues, Christophe Guinet, Rachel Berzins, Karin Bilo, Philippe Gaspar, Benoît de Thoisy, Yvon Le Maho, Damien Chevallier

“…The dispersal and diving patterns of the turtles revealed several behavioral adaptations to the strong hydrodynamic processes induced by both the North Brazil current and the Amazon River plume. All green turtles migrated south-eastward after the nesting season, confirming that they coped with the strong counter North Brazil current by using a tight corridor close to the shore. …”

Larval dispersal of Brachyura in one of the largest estuarine/marine systems in the world. by Francielly Alcântara de Lima, Davi Butturi-Gomes, Marcela Helena das Neves Pantoja, Jussara Moretto Martinelli-Lemos

“…The probability of occurrence of Portunidae is higher in ocean water (≥ 33.5); Grapsidae, Panopeidae, and Pinnotheridae is higher in intermediate and ocean salinity waters (25.5 to 33.5); Ocypodidae, Sesarmidae and Calappidae is higher in estuarine and intermediate salinity waters (5 to 25.5), whereas Leucosiidae, euryhaline, occur in all salinities (5 to 33.5). Furthermore, the Amazon River seasonal flow and plume movement throughout the year not only regulate the larval distribution and dispersion of estuarine species but are also fundamental for the ACS species, providing the necessary nutrient input for larval development in the region.…”
