Overview
This study addresses deficiencies in global bee species richness estimates through statistical modelling to establish lower bounds at global, continental, and country scales. Bees function as keystone pollinators in ecosystems, yet comprehensive species inventories remain incomplete. The research quantifies undescribed biodiversity and identifies systematic taxonomic gaps across geographic regions.
Methods and approach
The authors employed statistical estimation techniques to generate species richness lower bounds using existing occurrence data and taxonomic records. The analysis examined correlations between taxonomic gaps and multiple variables including gross domestic product per capita, observed species richness, occurrence record density, and database completeness. A statistical R-package framework was developed to enable reproducible estimation of species richness for additional taxa and geographic scales.
Key Findings
Global bee species richness is estimated between 24,705 and 26,164 species, representing an 18-25% increase above currently recognized diversity. This gap corresponds to approximately 32-45 years of continued taxonomic research at current rates. Substantial undescribed biodiversity concentrations were identified in Asia, Africa, and the Americas. Taxonomic gaps demonstrated significant correlations with economic development indicators, regional species richness patterns, sampling effort metrics, and data infrastructure completeness.
Implications
The results establish quantitative baselines for bee diversity assessment and highlight systematic regional disparities in taxonomic knowledge. The disproportionate concentration of undescribed species in developing regions of Asia, Africa, and the Americas reflects geographic and economic biases in taxonomic research capacity and infrastructure. These findings support prioritization frameworks for conservation efforts and ecosystem assessment in understudied regions.
