This recently published volume was prepared in commemoration of the 40th anniversary of the chimpanzee research project at Taï Forest, Côte d’Ivore. As already introduced by Wittig (2018), the Taï Chimpanzee Project began in 1979 by Christophe and Hedwige Boesch. The project has been continued since then and is now one of the world’s most eminent primate research projects.
From this volume, we can learn how long-term logistic efforts have been essential to run a large research project as well as to continue conservation actions for the target species. It is also interesting to see that some chapters are allocated for observation protocols and data sharing methods. Such common protocols are essential for long-term monitoring by various researchers and contributed to elucidation of very basic, yet very important findings about demography, life history, culture, diet, behavioral diversity, etc. of this long-living species.
Although the direct behavioral observation is a basic research protocol employed at chimpanzee field sites, there are growing importance of contributions from lab works in recent decades, such as genetic analyses, endocrinological analyses, identifying microorganism ecology and cause of infectious diseases. Such field–lab collaborative works have been conducted since relatively early days at Taï, and several chapters in this volume are allocated for reviews of such types of studies there.
More specific research topics found in this volume are very wide: adoption, spatial integration of females, tool use, social play, female rank changes, association networks, sharing meat, vocalizations, gesture, spatial and temporal cognitive abilities and so on.
Altogether 42 authors have contributed to 28 chapters in this volume.
We sincerely congratulate the 40-year achievement of the Taï Chimpanzee Project and acknowledge their very important contributions to the primatological literature.
