Supplemental data for: Dominant wild pollinators of Moroccan crops are soil nesting and pollen generalist bees

Crop pollination by animals is a crucial ecosystem service that enhances the yield and the quality of 75 % of major food crops worldwide. Wild bees play a significant role in this process as they are diverse and abundant visitors to crops and are known for their efficiency. However, in many parts of the world, including Morocco, there is no available commented list of wild bee species responsible for crop pollination. Here, we investigated the presence of wild bees associated with agricultural landscapes and described key trait characteristics of these bee species. Pollinator communities were sampled by sweep net and pan trapping across a total of 263 fields containing nine flowering main crops in 2018-2019. Key crop-pollinating species were identified as those species which made up 5% or more of the individuals visiting the flowers of each crop.  Out of the 359 pollinator species occurring in agroecosystems, 156 were crop-associated bee species and only 26 bee species were classif..., , # Supplemental data for: Dominant wild pollinators of Moroccan crops are soil nesting and pollen generalist bees Dataset DOI: [10.5061/dryad.0gb5mkmgj](https://doi.org/10.5061/dryad.0gb5mkmgj) ## Description of the data and file structure The Supporting Information includes supplementary details on the study design, including the geographical framework, study sites, crop selection, and pollinator surveys (adapted from El Abdouni et al., 2022). It also presents the dominance of key crop-visiting bee species across different agroecosystems and crops, as well as the ratio of each species’ relative abundance on focal crops compared to their abundance outside the crops. Bees outside the crops include all individuals collected along transects on other flowering plants (crops and wild plants) as well as those captured using pan traps. In addition, it provides field occupancy values for each KCVBS recorded across the four studied regions. ### Files and variables #### File: Supporting_Infor..., ,
