A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Complex interactions in ant–plant mutualisms: The role of multiple ant food resources in mediating plant defence, pollination and fitness in a tropical shrub

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1137-1147, December 2025.
Our results show that ants reduced leaf herbivory on plants offering both EFN and trophobiotic insects. Although ants did not directly affect pollinator behaviour, leaf herbivory in plants hosting treehoppers indirectly influenced pollination by reducing both visit duration and frequency.

Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

open access: yesJournal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Influence of environmental conditions and seasonality on the metabolome and lipidome of Psychotria viridis leaves

open access: yesThe Plant Journal, Volume 123, Issue 2, July 2025.
Significance Statement The metabolic pathways presenting significant variation in response to seasonality were associated with energy production through the biosynthesis and consumption of carbohydrates. In contrast, the biosynthesis of flavonoids, flavones, and flavonols was linked to the cultivation location, whether in full sunlight or shaded ...
