mayo 12th, 2017 Mario Loyola

Biólogo Marino de la Universidad de Los Lagos, Chile; PhD en fisiología de macroalgas de la Universidad de Otago, New Zealand. Mi experiencia en investigación incluye cultivo de micro- y macroalgas, y evaluación de parámetros fisiológicos de macroalgas (e.g., reproducción, crecimiento, fotosíntesis y captación de nutrientes) bajo diferentes factores abióticos en condiciones controladas de laboratorio y terreno. Actualmente, mi interés de investigación se enfoca en el efecto de factores relacionados al cambio climático global (acidificación y calentamiento del océano) en la ecofisiología de macroalgas.
