Mussels as a model system for integrative ecomechanics

Area of Science:

• Marine biology
• Ecological modeling
• Biomechanics

Background:

• Mussels are ecologically dominant on rocky shores and crucial for aquaculture.
• Coastal environments face dynamic changes in abiotic conditions.
• These changes impact mussel structure, physiology, growth, and reproduction.

Purpose of the Study:

• To describe four categories of ecomechanical models for mussel biology.
• To link models across molecular, material, organismal, and population scales.
• To provide predictions for mussel populations under changing climatic conditions.

Main Methods:

• Development of four ecomechanical model categories: biochemical, mechanical, energetic, and population.
• Integration of models across different scales of biological organization.
• Application of mechanistic modeling to understand mussel responses.

Main Results:

• Ecomechanical models cover diverse aspects of mussel biology, including byssal attachment, energetics, population growth, and fitness.
• Recent advances allow linking these models across organizational scales.
• The integrated approach yields explicit predictions.

Conclusions:

• The integrated ecomechanical approach offers novel insights into mussel population dynamics.
• This framework is essential for predicting the fate of natural and farmed mussel populations in changing climates.
• Mechanistic models are key tools for understanding ecological responses to environmental change.
