Outline of Research at the Start

A new analytical approach to how global warming might affect regenerating tree seedlings in the forest understory. This study will provide quantitative fitness data on representative species grown under a climate warming scenario useful in predicting forest structure changes in the future.

Outline of Final Research Achievements

We have achieved the objective of quantifying tree seedling fitness for several species by using their photosynthetic response profiles in simulated effects of climate warming on seedling fitness (which we named LFP). Our findings suggest 1) forest canopy type has a large effect on LFP where the deeply shaded deciduous forest offer insufficient energy to sustain seedling fitness (LFP < 0); 2) simulated warming (current +1.5oC) has a species-specific effect on LFP and not all species showed a negative impact; 3) in a future with a longer canopy cover duration, LFP will decline in all species examined, some below the break-even point of LFP < 1.

Academic Significance and Societal Importance of the Research Achievements

Facing the onslaught of climate change, it is incumbent upon us to anticipate its impact- on forest dynamics, in this case. This study addressed the issue of quantifying the fitness of tree seedlings under simulated climate change and found a surprising diverse response to a +1.5oC warming.
