State of the art of knowledge of pollinators biodiversity in Mexico

Pollinator conservation is of great interest to humanity. Pollinators help to maintain the assembly of ecosystems, as well, allow the production of more than 75% of food crops. In recent decades, a decrease in the diversity and abundance of pollinating species has been documented, mainly in countries of Europe and North America. This highlights the need for policies for the conservation of pollinating species in the world. In Mexico, there are important gaps in the knowledge of pollinators. With exceptions, there is not a list of pollinator species, nor studies on their distribution, and only in a few cases are details of their natural history known. In this document, we present the first list of species of the main pollinator families in Mexico, which includes species of pollinating insects within the order Hymenoptera and Lepidoptera, and species of pollinating vertebrates within the order Chiroptera and Apodiformes. Likewise, we report information on the conservation status of the species as reported in NOM-059-SEMARNAT-2010 and the IUCN, on ecological interactions and endemism for 2,405 reported pollinator species and completeness of knowledge at different spatial resolutions. With this information, we fill in some of the gaps around the knowledge of biodiversity (Linnean, Wallacean, and Eltonian) of pollinators in one of the countries with the greatest diversity, such as Mexico.
