Implication

Comparative evaluation finds pan traps provide the most efficient, unbiased measurement of bee diversity across habitats, highlighting their suitability for standardized long-term monitoring.

Key Points

To systematically evaluate and compare the performance of six widely used bee sampling methods across multiple European biogeographical regions and habitat types for standardized monitoring.
Evaluated six sampling methods (observation plots, pan traps, standardized transect walks, variable transect walks, and trap nests using reed internodes or paper tubes) across European agricultural and seminatural habitats.
Assessed performance metrics including sample coverage, observed species richness, richness estimators, species composition, and collector bias evaluated via subunit-based rarefaction curves.
Pan traps were the most efficient method across all regions and habitat types, achieving the highest sample coverage and species richness with negligible collector bias.
Transect walks were relatively efficient but exhibited significant collector bias, whereas observation plots demonstrated poor sampling performance.
Trap nests had naturally low sample coverage due to specialization on cavity-nesting species, but both trap nest types collected unique species not detected by any other method.
