Línea 3: Fisiología del cambio global

DESCRIPCIÓN:

Mis intereses de investigación abarcan una amplia gama de temas, pero en su mayoría, dedicados a la fisiología ecológica con fuertes lazos en la ecología del comportamiento, ecología evolutiva y la biogeografía. En mi opinión, la comprensión de los procesos ecológicos y patrones evolutivos globales subyacentes sólo puede lograrse mediante una integración de estas disciplinas. El estudio de los mecanismos, los rendimientos y las tolerancias fisiológicas, contribuyen, según el taxón y la escala de estudio, a explicar la distribución, la abundancia y el éxito evolutivo de las especies y poblaciones endémicas, como introducidas (pestes, vectores de enfermedades) y de valor comercial (cultivos). En mi opinión, este esfuerzo se está convirtiendo cada vez más importante debido al ritmo acelerado de las perturbaciones ambientales inducidos por el hombre.

OBJETIVOS:

• Estudiar las respuestas fisiológicas, ecológicas y evolutivas al  cambio global
• Integrar aspectos de fisiología con manejode la biodiversidad
• Utilizar nuevas herramientas experimentales (genómica, biología molecular, toxicología) y teóricas (modelos matemáticos) para entender y predecir el impacto de  los cambios ambientales sobre la biodiversidad.

PROYECCIONES:

Entregar explicaciones y transferir a la sociedad conocimiento y propuestas sobre los impactos y respuestas de los organismos nativos, introducidos y pestes a los cambios ambientales rápidos.
