Geographic Variation of UV Stress Tolerance in Red Seaweeds Does Not Scale with Latitude Along the SE Pacific Coast

Geographic variation of phenotypic traits affects the capacity of species to withstand and adapt to environmental stress. Here, we examined how geographic origin influences UV stress tolerance of the red seaweeds Chondracanthus chamissoi and Gelidium lingulatum distributed along the South‐East Pacific coast between 20° S and 42° S. Seaweeds from six ( C. chamissoi ) and five ( G. lingulatum ) populations were grown under common‐garden conditions...
