Description Permafrost and post-fire stand density influence plant water relations and hydraulic traits in a Siberian boreal forest

Abstract:
Boreal forests may experience increased water stress under global climate change as rising air temperatures increase evaporative demand and decrease soil moisture. Increases in plant water stress can decrease stomatal conductance, and ultimately, decrease primary productivity. A better understanding of variability in transpiration and the drivers of plant water use can help elucidate the implications of climate change on boreal forest productivity and demographics. A large portion of boreal forests are located in Siberia. Plant water stress may be heightened in high latitude Siberian boreal forests, since the forests are underlain by permafrost, characterized by short growing seasons, and receive low amounts of precipitation (< 300 mm per year). This presentation focuses on a study of plant water relations and hydraulic traits in northeastern Siberia across two different stand densities that arose from differing fire severity.

The Asa Gray Seminar Series is sponsored by the Asa Gray Biological Society, and is the longest running seminar series at Utica College. Scientists are invited from throughout the region to present seminars on their ongoing research. All lectures are held in Donahue Auditorium, Gordon Science Center, at 4:00 p.m. An informal reception immediately follows. Call (315) 792-3028 for more information.
