The plant danger zone: Assessing different strategies to deal with abiotic factors
Our changing climate is exposing plants to higher CO2 levels, warmer temperatures, and greater frequency of droughts, yet we know surprisingly little about how these changes affect plant structure and function in many species. My talk will consist of four short stories examining these responses. First, I will review what we know about how plants alter their xylem structure and function in response to high CO2 concentrations. Second, I will present results on how plant hydraulics were affected by a constant increase in air temperature relative to ambient. Third, I will discuss results on the physiological responses of two species to repeated heatwaves and drought. And, finally, I will present a case study of why some tree species die during a severe drought while others do not. This talk will hopefully highlight the importance of a better understanding of plant responses to these stresses.
