Research topics: Coexistence mechanism of plants under the pollinator-mediated competition

Keyword

Summary: Many plant species depend on pollinators such as bees and birds for reproduction, and when multiple species share the same pollinator, pollinator-mediated competition occurs. Although classical theories have pointed out that such competition makes coexistence difficult, the coexistence of species-sharing pollinators is often observed in the field. In this study, we aim to elucidate the mechanism of species coexistence by combining experiments simulating field biological communities with a framework known as the modern coexistence theory.

Comment

We can easily find that multiple flower species grow sympatrically outside. However, "What kind of species pairs or environmental conditions enable stable coexistence?" is a classic but unclear question in ecology. It is extremely difficult to fully understand the mechanisms of natural ecosystems, where various species and environments interact in complex ways. I will continue my research activities to contribute to understanding even a small part of the complex ecological process.
