Optimizing survey effort for Euglossine bees in tropical forests

Research reveals that sampling Euglossine bees over larger areas—rather than small plots—increases the cost-benefit ratio of biodiversity monitoring while capturing diverse species compositions. The study, conducted across a 25 km² gradient in central Amazonia, found that bee assemblages varied significantly with soil nutrient levels, particularly phosphorus, and were sensitive to landscape quality changes driven by deforestation. This suggests that Euglossine bees can serve as effective bioindicators for conservation efforts, providing rapid insights into environmental stressors. The findings underscore the need for broader sampling strategies to better understand and address biodiversity loss in tropical forests.
