Coevolutionary transitions from antagonism to mutualism explained by the Co-Opted Antagonist Hypothesis

open access: yesNature Communications, 2021
While there is strong evidence that many mutualisms evolved from antagonism, how or why remains unclear. A study combining theory and a data-based model sheds light on how mutualisms evolve without extremely tight host fidelity and how ecological context

Welcome to the big leaves: Best practices for improving genome annotation in non‐model plant genomes

open access: yesApplications in Plant Sciences, 2023
Premise Robust standards to evaluate quality and completeness are lacking in eukaryotic structural genome annotation, as genome annotation software is developed using model organisms and typically lacks benchmarking to comprehensively evaluate the ...

The meta-gut: community coalescence of animal gut and environmental microbiomes

open access: yesScientific Reports, 2021
All animals carry specialized microbiomes, and their gut microbiota are continuously released into the environment through excretion of waste. Here we propose the meta-gut as a novel conceptual framework that addresses the ability of the gut microbiome ...

Microplastic exposure across trophic levels: effects on the host–microbiota of freshwater organisms

open access: yesEnvironmental Microbiome, 2022
Background Microplastics are a pervasive pollutant widespread in the sea and freshwater from anthropogenic sources, and together with the presence of pesticides, they can have physical and chemical effects on aquatic organisms and on their microbiota ...
