We study plant ecology based on plant functions and physicochemical processes. We focuse on interactions between plants and environment with spcial reference to physiological mechanisms such as photosynthesis, growth and resource acquisition and utilization.
Our recent interests are (1) plant responses to global climate change and (2) plant adaptation to local environment.
For (1), we have conducted experimental studies for functions of plants grown under elevated CO2 and warming. We also performed theoretical or simulation study to predict plant functions in future environment. Recently, we have started remote sensing study to assess plant and ecosystem functions using satellite and UAV.
For (2), we have studied "ecotypes" adapted to contrasting environments. Ecotype is a genetically differentiated type found in a single species. Because genetic differentiations among ecotypes are expected to result from local adaptation
We study how plants respond to environmental changes at various spatial scales from molecular to community and at various time scales from instantaneous to evolution with various approaches from field observation, experiment and theory. We are interested in optimization of plant productivity, which is a result of natural selection in the habitat of the plants. Mechanisms and significance of plant traits and behaviour are our targets, We are also interested in plant responses to global climate change.
The following are recent research themes:
Responses, acclimation and adaptation of plants to environmental changes
Ecophysiology of photosynthesis
Inter- and intraspecific interactions in plant communities
