Host-structured adult butterfly microbiomes share a common core across continents

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

Democratizing three-dimensional surface phenotyping: an open structured-light platform reveals and removes the projection bias in biological imaging

The paper introduces an open structured-light platform to measure 3D surface phenotypes, revealing that projection bias significantly underestimates surface area and can confound phenotype comparisons.

Canopies drive the reassembly of pollinator communities and interaction networks along tropical forest succession

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.

The floral illusion: A parasitic beetle mimics the scent of flowers to attract bees

The paper shows that beetle larvae mimic floral scents to attract bees by biosynthesizing volatile compounds similar to those of flowers.

UV photogrammetry for transparent and composite surfaces

This paper introduces UV speckle photogrammetry to enable 3D reconstruction of transparent and composite surfaces, achieving high accuracy and completeness.

Do camera light traps for moths provide similar data as conventional funnel light traps?

This study compares automated camera light traps (CLTs) with conventional funnel light traps (FLTs) for moth monitoring, finding CLTs perform well overall but under-sample active species like Sphingidae and over-sample calmer species like Geometridae.

Improving allometric models to estimate the proboscis length of tropical bees

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

Applying telecentric stereo 3D-measurement to small Lepidopterans - bridging the macro and the microscale with isotropic micrometer resolution

This paper develops a telecentric stereo 3D-measurement system for high-precision, isotropic micrometer-resolution imaging of small Lepidoptera moths.
