Owing to the extraordinary latitudinal extent, a strong orographic variability with very high
mountain tops, and the presence of deep valleys and steep slopes, the Andes and the …

This paper reviews the state of the art in the concept as well as in the application of sediment
budgets in sedimentary research. Sediments are a product of mass dispersal at the Earth …

Due to rising energy demands and abundant untapped potential, hydropower projects are
rapidly increasing in the Neotropics. This is especially true in the wet and rugged Andean …

We report Li isotope composition (δ 7 Li) of river-borne dissolved and solid material in the
largest River system on Earth, the Amazon River basin, to characterize Li isotope …

Increased energy demand has led to plans for building many new dams in the western
Amazon, mostly in the Andean region. Historical data and mechanistic scenarios are used to …

We use cosmogenic nuclide-derived denudation rates from in situ–produced 10Be in river
sediment to determine sediment production rates for the central Amazon River and its major …

The aim of the present study is to estimate the export fluxes of major dissolved species at the
scale of the Amazon basin, to identify the main parameters controlling their spatial …

Large river sediments are mostly derived from tectonically active mountain belts, but then
undergo a series of sedimentation, temporary storage and reworking episodes on their …

Aim Little is known about factors affecting the elevational and longitudinal zonation of
tropical Andean stream communities. We investigated epilithon, macroinvertebrate and fish …

Anthropogenic activities performed in the Ecuadorian Amazon have released potentially
toxic elements (PTEs) into the rivers, causing severe environmental pollution and increasing …
