1 Introduction Woods are renewable, abundant, and essential for many industrial segments [1]. In Brazil, the intense exploration of this highly useful and exquisitely designed natural material has placed some valuable woods such as Pau-Brasil (Paubrasilia echinata), rosewood (Dalbergia nigra), pine (Araucaria augustifolia), and Brazilian mahogany (Swietenia macrophylla, also known as Honduran mahogany) on the list of endangered species [2, 3].

Abstract Advances in omics technologies have enabled the in-depth study of microbial communities and their metabolic profiles from all environments. Here metagenomes were sampled from piranha (Serrasalmus rhombeus) and from river water from the Rio São Benedito (Amazon Basin). Shotgun metagenome sequencing was used to explore diversity and to test whether fish microbiomes are a good proxy for river microbiome studies.
