Visitas de investigadores

Dr. Donat-P Häder, Friedrich Alexander Universität (FAU), Alemania

El Dr. Donat Häder realizó ocho visitas para realizar trabajos de investigación en la EFPU en el período 2000-2013, que enfocaron principalmente en evaluar los efectos de la radiación ultravioleta en macroalgas de la costa Patagónica. También se realizaron otros estudios puntuales a lo largo del río Chubut, destinados a determinar sus condiciones físico-químico-biológicas.

Los trabajos realizados por el Dr. Häder en la región Patagónica fueron financiados por Consejo Nacional de Investigaciones Científicas y Técnicas, Secretaría de Ciencia y Técnica / BMBF (Alemania), Fundación Antorchas, Agencia Nacional de Promoción Científica y Tecnológica (ANPCyT) / DAAD (Alemania) y Soriano S.A.
