LÍNEA DE INVESTIGACIÓN

El foco principal de nuestras investigaciones es la ecofisiología, entendida como aquella aproximación mecanicista y funcional que permite comprender los patrones de distribución y abundancia de las poblaciones y comunidades vegetales. Estamos interesados en comprender como las interacciones planta-planta y planta-microorganismos pueden facilitar y mejorar el desempeño ecofisiológico de plantas nativas e invasoras en ambientes extremos, y como estas interacciones pueden verse afectadas por el cambio climático. Finalmente, estamos interesados en promover estrategias de reintroducción de la flora nativa y mejoramiento de cultivos agrícolas mediante el uso de biorecursos antárticos.
