lasse.tarvainen[at]bioenv.gu.se

Lasse Tarvainen

Lasse’s research focuses on understanding the processes controlling the gas exchange, resource use efficiency and performance of boreal and tropical tree species. Within Rwanda TREE, he explores the large interspecific variation in photosynthetic heat tolerance/avoidance strategies. He also uses novel experimental approaches to elucidate the links between carbohydrate starvation and hydraulic failure in predisposing trees to climate-induced mortality.
