A trait-based framework for dung beetle functional ecology.

Area of Science:

• Ecology
• Zoology
• Environmental Science

Background:

• Trait-based approaches are established for plants but less developed for animals.
• Dung beetles are crucial decomposers with limited trait-based ecological frameworks.
• Understanding organismal traits is vital for ecological roles and environmental responses.

Purpose of the Study:

• To propose a trait-based response-effect framework for animal functional ecology.
• To use dung beetles as a model system to develop and test this framework.
• To identify key traits and relationships for dung beetle ecological function.

Main Methods:

• Reviewed dung beetle traits responding to environmental variations (temperature, water, soil, etc.).
• Assessed trait-mediated effects on ecosystem processes (nutrient cycling, bioturbation, etc.).
• Categorized 66 identified traits into morphology, feeding, reproduction, physiology, activity, and movement.

Main Results:

• Identified 66 dung beetle traits as response, effect, or both.
• Documented 136 trait-response and 77 trait-effect relationships.
• Highlighted interrelationships between traits, environmental responses, and ecosystem effects.

Conclusions:

• The proposed framework provides a foundation for trait-based dung beetle ecology.
• The study identifies knowledge gaps and biases in current dung beetle research.
• The framework serves as a model for developing trait-based ecology in other animal taxa.
