Utility of the cellular energy allocation model for assessing food limitation stress in freshwater mussels.

ABSTRACT: Freshwater mussel populations are declining worldwide, but the causes and mechanisms of these declines are poorly understood. Biomarkers that reflect the health or fitness of individual mussels are needed for understanding causes of mussel declines, but existing approaches each have weaknesses. We conducted two laboratory experiments to examine the utility of the cellular energy allocation (CEA) model for assessing juvenile mussel responses to stress induced by food limitation. The CEA assesses the energetic status of an organism as CEA = E _a/E _c, where E _a is available energy reserves (total carbohydrates, protein, and lipids) and E _c is energy consumption, estimated using electron transport system (ETS) activity as a
