Investigating over 7,500 ecological facts recorded in the “Pokémon Encyclopedia.” A book that all generations can get lost in!
The “Pokémon Ecological Encyclopedia” summarizes Pokémon ecology through the new lens of real-world behavioral ecology. This book is based on over 7,500 ecological facts listed in the “Pokémon Encyclopedia” featured in the “Pokémon” series. The authors are Yoshinari Yonehara and Chihiro Kinoshita, both experts in behavioral ecology with Ph.D.s in Agriculture who have studied animal behavior. They go beyond the information in the “Pokémon Encyclopedia” to observe the movements and physical characteristics of Pokémon in the games, unraveling the relationship with their ecology.

The book is composed of four chapters: “Appearance and Form,” “Life,” “Interactions Between Pokémon,” and “Movement Ability.” In the third chapter, “Interactions Between Pokémon,” the authors summarize concepts like “symbiosis,” “territorial disputes,” and “herds” from an expert’s perspective. For example, small Pokémon like Metapod and Kakuna gather on Torterra’s back to build nests. You can truly observe how Pokémon “live together.”

In addition, the book delves into various aspects of Pokémon ecology, such as “differences between males and females,” “forms that change based on habitat,” and “ingenuity in obtaining food.” By using the information in this book as a reference, you might make new discoveries when thinking about your favorite Pokémon or playing the games. Please experience the magnificent world of “Pokémon” through this book.
