The truth is out there.
Research in the Ohashi Lab (aka Ecological Interactions Lab) covers a wide range of topics, with the common theme that they all involve plant-animal interactions. The Ohashi Lab uses field, indoor experimental, and computational approaches to elucidate how plants have evolved various floral traits and combinations to maximize fitness, mediated through interactions with diverse organisms. We often focus on how flower visitors such as bumble bees and other insects respond to variation in a set of floral traits at different spatial scales, based on foraging economics that has been neglected in the past studies of floral evolution. We have learned from our research that one could effectively predict and test what behavioral responses floral traits have evolved to elicit from animals by incorporating knowledge from behavioral ecology, animal physiology, and animal psychology. To promote such interdisciplinary research in evolutionary ecology, we have also collaborated with researchers from diverse fields, such as behavioral ecologists, animal physiologists, plant taxonomists, chemical ecologists.
Our current collaborators are: James Thomson (Emeritus Professor, University of Toronto, Canada), Tetsukazu Yahara (Emeritus Professor, Kyushu University, Japan), Andreas Jürgens (Professor, Technical University Darmstadt, Germany), Klaus Lunau (Emeritus Professor, Heinrich Heine University Düsseldorf, Germany), Nobumitsu Kawakubo (Professor, Gifu University), Lina Kawaguchi (Research Administrator, Kyoto University), Miki Suzuki (Reserach Associate, Yamanashi University), Daichi Funamoto (PhD Student, Kobe University), Martin Burd (Associate Professor, Monash University, Australia; with many others in international project on the evolution of floral color in angiosperms).
The followings are some selected topics on which we are currently working. We are also interested in the interactions between a wide range of other "living" organisms, such as the relationships between individuals of the same species, between prey and predator, and between human activities and organisms. Those who wish to work on a slightly different topic than below are also welcome to contact us.
Strangely enough, the higher you climb,
the more you could see the other peaks.
A feeling of recognition and respect
for others will grow within you.
