This study identifies a common core microbiota in adult butterflies across continents, showing host taxonomy drives microbiota structure more than environment.

The paper examines how canopy structure influences pollinator community recovery and interaction networks during tropical forest succession, finding that stratification is a stronger predictor of diversity than forest legacy.

This study examines how nutritional preferences influence pollen foraging networks in alpine pollinator communities, finding that both bumblebees and hoverflies prefer pollen with low fatty and amino acid content.

The paper examines sex-specific foraging strategies and sensory traits in Heliconius himera butterflies, finding females carry more pollen but both sexes forage on similar plants, with males having larger eyes and females larger mushroom bodies.

This study combines NLP and genome analysis to predict bacterial phenotypes by integrating literature and genomic data, revealing gene-phenotype correlations and hub species in microbial communities.

The paper develops new allometric equations to estimate proboscis length in tropical bees, finding that existing temperate models lack accuracy for tropical species.

The paper shows that reducing land use increases invertebrate abundance but not diversity in grasslands, with effects influenced by surrounding land use practices.

The paper investigates the genomic capabilities of bacteria in grapevine crown galls, finding that opine utilization genes are widespread among both virulent and non-virulent strains, supporting coexistence and community shaping.

The paper curates and expands reference databases for ITS2 DNA barcoding in vascular plants by automating curation and manually adding new sequences.

The paper uses CRISPR/Cas9 to introduce nonsense mutations in honeybee AmGr3 gene, demonstrating its specificity for fructose detection and showing measurable behavioral changes in mutants.
