Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature
Abstract Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study assessed individual thermal plasticity of Atlantic cod ( Gadus morhua...
