Evolutionary approaches for studying functional morphology: examples from studies of performance capacity

Area of Science:

• Evolutionary Biology
• Ecology
• Biomechanics

Background:

• Performance studies are crucial for understanding adaptation and fitness.
• The mechanistic links between habitat use, morphology, and performance are often unclear.
• Behavior's role in morphology-performance relationships is understudied.

Purpose of the Study:

• To explore the interplay of habitat use, morphology, and performance in lizards.
• To investigate how behavior influences the link between morphology and performance.

Main Methods:

• Phylogenetic analyses of Anolis lizard habitat use and perch diameter.
• Kinematic studies of high-speed locomotion in diverse lizard species.

Main Results:

• Anolis lizards select perches that optimize their locomotor performance.
• A trade-off exists between sprinting on broad surfaces and maneuvering on narrow ones.
• Behavioral strategies significantly enhance lizard performance, bridging morphology and function.

Conclusions:

• A mechanistic approach integrating habitat use, morphology, and behavior is vital for evolutionary studies.
• Behavior plays a critical role in mediating the relationship between physical traits and performance.
• Understanding these links provides insights into adaptation and niche partitioning.
