Wilmer Adelso Tezara Fernández Dr. in Sciences, mention in Botany, 1996. B.Sc. in Biology, 1991. Faculty of Sciences, Universidad Central de Venezuela (UCV). Professor-Researcher (since 1996/2022), Full Professor, Exclusive Dedication (UCV). Assistant Professor 1 2023 at FACAP-UTLVTE. Theses supervised: 3 Doctors of Science, 4 Master's Theses, 16 Bachelors in Biology, and 6 Agronomists. Due to eminent climate change, knowing the mechanisms of acclimatization to drought, as well as studying the photosynthetic response to the increase in [CO2] is of great interest. In 1991, he started his research career in the area of Plant Ecophysiology, studying mechanisms of photosynthesis regulation in different species in xerophytic ecosystems in Venezuela. During his PhD and Postdoctoral internship, he studied the photosynthetic response to water deficit and elevated [CO2] in sunflower at Rothamsted Experimental Station, England. He demonstrated that water deficit inhibits photosynthesis by decreasing the coupling factor and thus ATP synthesis, reporting a positive effect when growing plants at high [CO2]. Currently, his efforts have been carried out in cocoa ecophysiology; providing information on tropical woody crops within the benefits of agroforestry systems.
