INS 15-8 - Synergy among scientists aids synergism study: redband trout resilience facing hypoxic and thermal stress

Redband trout (Oncorhynchus mykiss gairdneri) are an integral component of their local ecosystem. This study aims to understand how genetic diversity and phenotypic plasticity affect this sensitive species’ response to hypoxic and thermal stress induced by anthropogenic climate change. With collaborative efforts from several groups, age-0 trout were collected from 3 distinct habitats and reared in a common garden environment at 15°C or 21°C modeling cold montane and desert streams, respectively. We found that thermal and hypoxia tolerance phenotypic responses significantly differed as a result of plasticity, while the combination of both stressors had an additive effect.
