The Amazon basin is the largest watershed on Earth. Although the variability of the Amazon hydrological cycle has been increasing since the late 1990s, its underlying causes have remained elusive. We use water levels in the Amazon River to quantify changes in extreme events and then analyze their cause. Despite continuing research emphasis on droughts, the largest change over recent decades is a marked increase in very severe floods. Increased flooding is linked to a strengthening of the Walker circulation, resulting from strong tropical Atlantic warming and tropical Pacific cooling. Atlantic warming due to combined anthropogenic and natural factors has contributed to enhance the change in atmospheric circulation. Whether this anomalous increase in flooding will last depends on the evolution of the tropical inter-ocean temperature difference.

One of the major challenges in ecology is to understand how ecosystems respond to changes in environmental conditions, and how taxonomic and functional diversity mediate these changes. In this study, we use a trait-spectra and individual-based model, to analyse variation in forest primary productivity along a 3.3 km elevation gradient in the Amazon-Andes. The model accurately predicted the magnitude and trends in forest productivity with elevation, with solar radiation and plant functional traits (leaf dry mass per area, leaf nitrogen and phosphorus concentration, and wood density) collectively accounting for productivity variation. Remarkably, explicit representation of temperature variation with elevation was not required to achieve accurate predictions of forest productivity, as trait variation driven by species turnover appears to capture the effect of temperature. Our semi-mechanist...

Donde habitan los neba es un libro que recoge los resultados de las investigaciones realizadas durante casi una década en los territorios de varias comunidades urarinas asentadas en el río Chambira y en uno de sus auentes, el río Tigrillo, en pleno corazón de uno de los complejos de humedales más importantes del planeta, el Abanico del Pastaza. Representa el trabajo multi e interdisciplinario y colaborativo llevado a cabo entre las comunidades, las federaciones locales (FEPIURCHA y FEIURCHA), la Universidad de St Andrews en el Reino Unido y el Instituto de Investigaciones de la Amazonía Peruana - IIAP. La información contenida en su interior amplía el conocimiento existente sobre este importante paisaje biocultural de nuestra Amazonía, mostrando la riqueza cultural y ecológica de los territorios urarinas y desvelando el vínculo todavía existente entre naturaleza y cultura en ...
