Alternative plant designs: consequences for community assembly and ecosystem functioning.

Area of Science:

• Ecology
• Evolutionary Biology
• Trait-based Ecology

Background:

• Alternative organism designs, where distinct trait combinations achieve the same function, are prevalent in nature and drive species diversity.
• Current ecological studies often overlook alternative designs, assuming linear trait trade-offs influence species fitness and niche differentiation.

Purpose of the Study:

• Review the concept of alternative designs and their empirical support in plants.
• Discuss how trait integration levels affect performance and function.
• Highlight the implications of alternative designs for understanding species coexistence and ecosystem functioning.

Main Methods:

• Literature review on alternative designs and trait-based ecology.
• Analysis of empirical evidence in plants demonstrating complex trait-fitness relationships.
• Conceptual framework integrating trait hierarchy and organism integration levels.

Main Results:

• Alternative designs can lead to increased functional diversity and support species coexistence.
• Ignoring complex trait interactions can obscure mechanisms of coexistence and ecosystem effects.
• Considering trait integration levels aids in selecting traits directly linked to performance and function.

Conclusions:

• Alternative designs significantly impact trait patterning and community assembly processes.
• Environmental filtering can lead to decreased or increased functional diversity depending on the consideration of alternative designs.
• Alternative designs enhance ecosystem functioning stability under environmental changes.
