Effects of floral resources on honey bee populations in Mexico: Using dietary metabarcoding to examine landscape quality in agroecosystems

Ecology and Evolution, Volume 14, Issue 6, June 2024.
This study investigates how landscape diversity and climatic factors affect the populations and nutritional health of honey bee colonies in Mexico. It was found that greater landscape diversity correlates with higher pollen diversity, while areas with more agriculture and urbanization show lower bee densities.
