Understanding Temperature Constraints on Fish Performance
Temperature shapes the physiology and performance of ectotherms, driving species redistributions on a global scale. When physiological rates are measured across temperatures, they typically form a curve where performance rises to an optimal temperature before dropping to zero. My project builds a global database of thermal performance curves from existing literature for key traits in marine and freshwater fish. By analyzing temperature-dependent traits, we aim to understand how temperature limits performance across fish species and how these patterns aligns with their natural thermal ranges. These insights are key to predicting species range shifts and ecosystem impacts under climate change.
