Important Crop Pollinators Respond Less Negatively to Anthropogenic Land Use Than Other Animals.

Area of Science:

• Ecology
• Conservation Biology
• Agricultural Science

Background:

• Animal-mediated pollination is vital for global food security, supporting most major food crops.
• Anthropogenic pressures like habitat loss and land-use intensification threaten pollinator communities and pollination services.
• Previous studies often overlooked species-specific contributions to pollination, impacting biodiversity-pollination relationship assessments.

Purpose of the Study:

• To investigate how terrestrial species with varying crop pollination contributions respond to land-use type, intensity, and surrounding habitat availability.
• To analyze the global impact of anthropogenic landscapes on pollinator communities and their ecosystem service provision.

Main Methods:

• Utilized a novel species-level ecosystem service contribution matrix.
• Employed mixed-effects models to analyze global responses to land-use variables.
• Assessed the relationship between species' pollination contribution and their sensitivity to human disturbance.

Main Results:

• Species with higher crop pollination contributions showed less negative, and sometimes positive, responses to human land disturbance.
• High-contribution pollinators appear less sensitive to anthropogenic land conversions.
• Humans have become more reliant on these high-contribution species for crop pollination.

Conclusions:

• Crop pollination may exhibit resilience to anthropogenic land conversions due to the differential responses of key pollinator species.
• Understanding landscape impacts on pollinator communities is critical for maintaining pollination services and ensuring food security.
• Conservation strategies should consider the varying roles of species in ecosystem service provision.
