For the first time, multi-layered quantitative data is used to analyze the production impact of specific commodities on deforestation in the Amazon. Operating at a sub-national level, this granular understanding can empower (sub-)regional, national and international actors to support sustainable land-use and forest conservation...

Understanding the spatial and temporal variability of methane ebullition is key to mitigating its release into the atmosphere. Through an acoustic survey of ebullition along 274 km of the Amazon River, spanning four ecosystem types in three different river types, this article aims to assess the variability and characteristics of ebullition across the basin.

To address both the light conditions and practical concerns, the authors investigated whether supplementary light from a hand-held LED torch might offer a viable solution.

Management strategies such as rewetting and revegetation have been employed to improve them, but it has not been clear how these efforts have impacted the functioning of blanket bogs. Here, the authors assessed the composition and responses of testate amoebae communities to restoration and investigated their potential as bioindicators of peatland health.
