Instantaneous Photosynthetic Response To Temperature Of Mature Forest Canopies And Experimentally Warmed Seedlings, Alida C. Mau Jan 2015

Instantaneous Photosynthetic Response To Temperature Of Mature Forest Canopies And Experimentally Warmed Seedlings, Alida C. Mau

Dissertations, Master's Theses and Master's Reports - Open

Tropical trees have been shown to be more susceptible to warming compared to temperate species, and have shown growth and photosynthetic declines at elevated temperatures as little as 3oC above ambient. However, regional and global vegetation models lack the data needed to accurately represent physiological response to increased temperatures in tropical forests. We compared the instantaneous photosynthetic responses to elevated temperatures of four mature tropical rainforest tree species in Puerto Rico and the temperate broadleaf species sugar maple (Acer saccharum) in Michigan. Contrary to expectations, leaves in the upper canopy of both temperate and tropical forests had temperature …


Investigating The Effects Of Short- And Long-Term Climatic Variation On The Water Use Of Three Northern Hardwood Tree Species, Alex R. Collins Jan 2015

Investigating The Effects Of Short- And Long-Term Climatic Variation On The Water Use Of Three Northern Hardwood Tree Species, Alex R. Collins

Dissertations, Master's Theses and Master's Reports - Open

Many tree species are expected to decline in the northern Midwestern United States due to climate change increasing annual temperature 3-5º C by 2100. Sugar maple (Acer saccharum), an economically important timber and syrup species, is not expected to be sustainable in its current range under projected future climate, while trembling aspen (Populus tremuloides) and red maple (Acer rubrum) are expected to react more favorably to climate change. The success of individual tree species is dependent on how climate change will alter a species environment in regards to water use. Climate change could …
