【Abstract】
The significance of individual variation, beyond the scope of the group averages, has been acknowledged within the field of ecology. In particular, in behavioral science, the concept of “animal personality” has emerged as a burgeoning research topic over the past two decades. Currently, the majority of behavioral ecologists (though not all) recognize the impact of animal personality on various ecological contexts. However, the extent of our understanding regarding its implications remains uncertain. It is timely to review the accumulated knowledge on the implications of animal personality. This symposium specifically aims to elucidate the consequences of animal personality in the contexts of social interactions, group dynamics, and inter-specific interactions.
Moreover, the symposium will include a discussion session focusing on human-induced rapid environmental changes (HIREC). While the original framework of HIREC considers substantial individual differences in behavioral responses to novel challenges or resources, addressing more specific scenarios is valuable. Key questions include: (1) Does HIREC change the composition of individual behavioral types, resulting in modified populations (referred to as personality bias)? and (2) How does personality bias influence the outcomes of social, group, and interspecific dynamics? By gathering feedback from a diverse group of ecologists, we aim to integrate the research topics of animal personality and HIREC, thereby establishing a new direction for future research.
