環境変動に対する生態系機能および生態系サービスの安定性やその維持メカニズムの解明は、生態学の主要課題の一つである。生物多様性は、生態系の安定性(ecosystem stability)を向上させる最も基盤的な要因である。とくに近年は、時間的安定性(temporal stability/invariability)、抵抗性(resistance)、回復性(recovery)、レジリエンス(resilience)といった生態系の安定性のさまざまな側面に対して、生物種の環境応答の多様性(応答多様性:response diversity)や、種間での環境応答の非同調性(species asynchrony)の効果の検証が急速に進んでいる。

There is an urgent need to understand the stability of ecosystem functions and services in response to environmental change. The insurance effect of biodiversity posits that biodiversity enhances and stabilizes ecosystem functioning. However, the precise mechanisms through which this stabilization occurs remain an open question, and likely vary across contexts. Moreover, ecosystem stability is a multidimensional concept, including temporal and spatial invariability, resistance to and recovery from disturbance, further hindering identification of a single causal driver of stability. Recent work demonstrates the contributions to ecosystem stability of variations in direction and/or magnitude in species responses to environmental changes (that is, response diversity) and the variation in timing of environmental responses among species (species asynchrony). Particularly, response diversity has been theoretically demonstrated to reduce the negative impact of environmental fluctuations on communities, acting as a potentially key determinant of ecosystem stability, perhaps indirectly, through its effects on species asynchrony. However, a uniform method for evaluating response diversity has not been established so far.
Through this symposium, we will bring together researchers working on the diversity–stability relationship in Japan. The keynote presentation will propose a new indicator of response diversity for use in empirical studies. There will also be case studies on species asynchrony and response diversity from manipulative experiments and observations. We will review diversity–stability studies, including topics such as the relationship between species coexistence and ecosystem functioning and stability. We hope this symposium will catalyze a new wave of mechanistic diversity–stability studies in Japan, with a focus on response diversity and species asynchrony at their core.
