Tyeen Taylor, a Ph.D. student in the UA’s department of ecology and evolutionary biology, focuses his research on tropical forest responses and feedbacks to climate change. His study sites are The University of Arizona’s Biosphere 2 and the Amazon forest. The Amazon forest contains a quarter of the world’s land species, and, through photosynthesis and respiration, processes twice the amount of carbon dioxide that is emitted by humans each year. Any responses of the Amazon forest to climate change will have large feedbacks to global climate and biodiversity. Ty identifies forest microhabitats that resemble the projected future climate (i.e., drier and hotter in the Amazon). He uses these to analyze the effects of the future climate on forest composition and function. Specifically, he analyzes the differences in tree functional characteristics, like wood and leaf traits, and the (phylogenetic) structure of tree species assemblages between these microhabitats and the surrounding matrix of forest living under normal climate conditions. Results from his research will inform more accurate climate models and the identification of conservation priorities in the Amazon.
