The ecosystem services provided by social insects: traits, management tools and knowledge gaps

Area of Science:

• Ecology
• Conservation Biology
• Entomology

Background:

• Social insects (ants, bees, wasps, termites) are vital ecological community components.
• They are significant providers of ecosystem services (ESs), yet many are undervalued.
• Their unique traits contribute to their role as ecosystem engineers and service providers.

Purpose of the Study:

• Analyze traits of social insects that enhance their ecosystem service (ES) provision.
• Compile and assess management strategies to improve social insect-mediated ESs.
• Identify knowledge gaps concerning social insect-provided ESs.

Main Methods:

• Literature review and synthesis.
• Analysis of social insect traits (biomass, abundance, mutualisms, biogenic structures, chemical defenses, caste systems, communication, food storage, lifespan).
• Assessment of management strategies and conservation approaches.

Main Results:

• Social insects provide at least 10 distinct ESs, though many are poorly understood.
• Key traits include high biomass, mutualistic associations, biogenic structure creation, and efficient cooperation.
• These traits enhance their potential, constancy, and efficiency as ES providers.

Conclusions:

• Social insects' traits support their role as effective ES providers, adaptable to management.
• Conservation approaches are vital for managing these services, with potential for habitat restoration.
• Integrated evaluation of services and disservices (e.g., invasive species) is necessary.
