Community‐Level Metabolic Shifts Following Land Use Change in the Amazon Rainforest Identified by a Supervised Machine Leaning Approach

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 2, April 2025.
A machine learning (ML)‐derived metagenomic analysis of soils collected from Amazon forests and long‐term established pastures showed different microbial community strategies towards carbohydrate metabolism and energy allocation. The ML approach allowed the development of metabolic maps that explained process‐level modifications to the C and N ...

Yield and Stability of Three Tropical Forage Grasses Cultivated as Pure or Mixed Stands

open access: yesGrass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Multispecific pastures are considered more sustainable to animal production than monocultures. However, studies on mixtures of tropical grasses are underexplored. We aimed to assess whether a mixture of three contrasting growth strategies of perennial tropical forage grasses could outperform their respective monocultures in terms of forage ...
